== Description ==

The '''{{Specs|name}}''' is the introductory helicopter of the Swedish helicopter tech-tree. The model is originally based on the Italian license manufactured variant of the Bell 204B (UH-1). Originally acquired in 1962 for helicopter rescue services, the platform saw extensive use in both the Swedish Air Force and Army. Serving for nearly 40 years, the HKP3 went through two modernization programs relating to its powerplant. Originally being delivered as the HKP3A, the type was quickly deemed underpowered prompting the decision to give it a more capable engine, redesignating it as the HKP3B. While this solved the problem of handling, the Army saw more potential in increasing the lift further by lengthening the tail and extending the rotor, thus creating the {{PAGENAME}} we see represented in game. While the platform was not originally designed for anti-tank missions, the Army did extensive trials to incorporate the BANTAM missile to the HKP3. Although these tests were deemed successful, the military opted to not procure any missile armament for the type.

In game, the {{PAGENAME}} is the introductory helicopter for Sweden. As it is one of the earliest examples of ATGM carrying helicopters it faces much less advanced threats while still being able to engage from a safe distance. While these missiles pack a significant punch compared to unguided rockets, the tradeoff comes at velocity as they take an extreme amount of time to reach the target, requiring patience and strategy to utilize correctly.

== General info ==
=== Flight performance ===
{{Specs-Heli-Flight}}

As the {{PAGENAME}} is a utility helicopter by nature, the flight performance is mostly a result from the carrying capacity the platform was made for. As the Huey family was primarily designed for troop transportation the resulting agility is favourable compared to usually larger or weaker utility helicopters. The {{PAGENAME}} sports a fantastic climb rate that holds up even against more modern examples. Keeping the nose pointed at targets is easily done thanks to the well responding control surface, albeit with slight limitations. Since the helicopter was mostly designed to quickly move between locations, it struggles to perform more advanced combat manoeuvres, especially when trying to roll the aircraft.

=== Modifications and economy ===

As the {{PAGENAME}} gets its full weaponry stock, all research can be dedicated to flight performance and survivability. It is recommended to focus on engine upgrades for greater climb rate. Quickly researching Flak jacket is also preferable as it greatly increases pilot survivability, which comes in handy when in close combat against machine guns.

{{main|RB 53 Bantam}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 6 x RB 53 Bantam missiles

== Usage in battles ==

Since the {{PAGENAME}} is one of the first examples of anti-tank helicopters available for research, the characteristics and gameplay usually revolves around its limitations. While the improved Huey platform offers great power, mobility and carrying capacity, the nature of it being primarily for utility limits both how agile and survivable the helicopter is. This means the {{PAGENAME}} can easily get into position, but often struggles to defensively act when confronted by enemy vehicles.

Counteracting these downsides can be done in two different approaches, depending on situation and terrain. The first being a more distanced gameplay, focusing on utilizing the 2 km range the BANTAM missiles offer. While these travel at painstakingly slow speeds, the damage and pinpoint accuracy they provide more than offsets the problem. Since the {{PAGENAME}} is situated at a low battle rating, there is rarely any SPAA that can have a clear shot when using terrain to its advantage. The only counterbalance of this playstyle is how much it relies on enemy positioning. While other missiles usually reach the target before it relocates, the BANTAM requires a firing window that's usually far over 20 seconds in travel time, giving opponents ample time to avoid the missile by driving into cover either on purpose or by accident. Since the missiles require visual with the target to guide, trying to accurately guide them onto an opponent from a distance leaves the {{PAGENAME}} vulnerable for an equal amount of time, making SPAA countering, one of the strengths of helicopters, near impossible to perform.

The second playstyle is centered around trying to maximize the efficiency of the BANTAM missiles by closing the traveling distance, lowering the amount of time spent on each target. The best way to perform this playstyle is by staying low to the ground while approaching the battlefield, then using the horizontal momentum to gain altitude over the target area. By pivoting the helicopter to fire straight downwards, players can essentially use the low speed of the BANTAM to accurately guide them onto the rooftops of unsuspecting tankers below. This requires a lot of practice and getting familiar with helicopter controls, but can allow for multiple threats to be dealt with in a short timeframe. While this can on paper be the most effective way to play the {{PAGENAME}}, put into practice the reckless approach will often leave the craft vulnerable to SPAA and roof-mounted machine guns. Selecting between the two different playstyles should as such be done by evaluating which one seems the most effective given the map and state of the match. Spawning the helicopter early in a smaller map will often favour the second approach, while a later spawn on more open large-scale maps more commonly favour the first approach.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish utility helicopter {{Battle-rating}}. It was introduced in [[Update "Wind of Change"]].

== General info ==
=== Flight performance ===
{{Specs-Heli-Flight}}

The {{PAGENAME}} is a light utility helicopter operated by the Swedish army. Although different in designation the helicopter is identical in flight performance to the German [[BO 105 CB-2]], only being differentiated in loadout options. This family of helicopters are some of the most agile helicopters in game, able to perform most advanced maneuvers without sacrificing a lot of altitude. All control surfaces are incredible responsive and quickly react to any input a pilot throws at it. This can often allow pilots to be much more aggressive when facing gunfire, as the helicopter can change directions almost immediately. On top of this, the {{PAGENAME}} is one of the smallest helicopters in the game, making it difficult to both spot and shoot down. It is this small profile that allows the helicopter to maneuver with ease, as it is very lightweight. A consequence, however, of this weight saving, is the lackluster engine power that despite its size makes the {{PAGENAME}} slow in both top speed and climb rate. Although not detrimental to its general combat effectiveness, it can be a noticeable downside especially when avoiding incoming aircraft, or trying to gain altitude over mountains.

=== Survivability and armour ===
{{Specs-Heli-Armour}}

As the {{PAGENAME}} is a light utility helicopter, the vehicle lacks any form of protection against small arms fire. The helicopter has directly exposed pilots at the front, and a fuel tank stretching the entire underside of the vehicle. This makes it so that a lot of hits from below sets the helicopter ablaze, while most hits from the front knocks out both crew members. This makes the flak jacket modification a vital component for protection as it can allow the crew to survive longer in battle. The engine is also prone to catching fire, and the lack of significant thrust makes the loss of one of the two powerplants enough to take it down.

{{main|RB 55B Heli TOW|FN M3P (12.7 mm)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 8 x RB 55B Heli TOW missiles

The eight TOW missiles is the most ideal loadout for the {{PAGENAME}} as it allows for a lot of stopping power against ground vehicles. Having this amount of missiles is fantastic, especially for its class, where four or six missiles is usually the average. Despite this quantity the general flight performance stays almost identical, still allowing for aggressive maneuvering

* 2 x 12.7 mm FN M3P machine guns (150 rpg = 300 total)
* 1 x 12.7 mm FN M3P machine gun (400 rpg) + 4 x RB 55B Heli TOW missiles

A researchable modification on the {{PAGENAME}} is the installation of 12.7mm gunpods fixed against the fuselage. This weapon type can be carried one on each side or in combination with the TOW launcher. Although this weapon type limits the quantity of missiles the helicopter is able to carry, it gives the {{PAGENAME}} some form of self defense against flying targets, as it lacks any sort of air to air capabilities otherwise. It can be worthwhile for a player to carry a combination of missiles and guns if they are expected to face off against other helicopters.

== Usage in battles ==

As this helicopter is incredibly light with a lot of firepower for its class, the general playstyle should be one of risk-reward. The {{PAGENAME}} can be played effectively in both long range and close range territory, depending on what a pilot prefers. Both playstyles can be equally effective employed correctly but have their own drawbacks.

'''Defensive playstyle'''

As the {{PAGENAME}} carries missiles with almost 4 kilometers of firing range, staying out of sight from close range SPAA is one way to approach the helicopter. A pilot can in this case decide to utilize cover around the map, hiding behind buildings and mountains peeking out of cover to fire on stationary targets. This playstyle is most optimal when the enemy has a lot of SPAA active. Most of these players will be stationary in their spawn point looking for enemy helicopters, which the {{PAGENAME}} can take full advantage of.

As a downside to this playstyle the {{PAGENAME}} is very vulnerable to incoming aircraft, as the helicopter has to operate entirely by itself. Being situated in a high battle rating without any strong defensive weaponry makes it a perfect prey for enemy pilots. The playstyle also limits the offensive capabilities of the {{PAGENAME}} as the missiles are much slower than its soviet counterparts. This means that moving targets can escape into cover before the missile impacts, resulting in wasted time. On top of this the helicopter requires visual contact with the enemy while firing, sometimes requiring upwards of 20 seconds spent outside of cover.

'''Aggressive playstyle'''

Almost opposite to the defensive one, the {{PAGENAME}} can counteract the slow guidance speed and weak air-to-air protection by playing inside the map boundaries. This allows the {{PAGENAME}} to take advantage of allied SPAA units using them as cover, allowing a player to spend more time focusing on ground targets instead. On top of this, the closer distance between the helicopter and target allows for less time where the enemy can retaliate. The slow travel speed of the TOW missiles will instead work in a players favor as it allows for better accuracy when guiding.

This way of fighting requires a bit of map knowledge, and spacial awareness as enemies can spawn in their own SPAA to retaliate almost immediately. On top of this, a closer proximity puts the {{PAGENAME}} in range of roof mounted machine guns, which are heavily prominent at this battle-rating. Although you can hide behind cover or stay directly above a target to counter it, this only works in the short term as the longer you stay alive the more people will become aware of your presence, putting more and more emphasis on staying out of sight.

'''Pros:'''

* Great agility - One of the most maneuverable helicopters in the game
* Large missile payload
* Small profile
* Great stock performance - Comes with all eight missiles from the start

*

'''Cons:'''

* Weak powerplant - Slow climb and top speed
* Poor survivability
* Lackluster air-to-air protection - only has access to optional 12.7mm machine guns
* No Night Vision Devices (NVD)
* No Radar Warning Receiver (RWR)
* Missiles have to be guided manually
* Small firing window - helicopter must be pointed at target to guide effectively.

| usage = other versions
| link = SAAB 37 Viggen (Family)
}}
{{Specs-Card
|code=saab_aj37
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish strike aircraft {{Battle-rating}}. It was introduced in [[Update "Ground Breaking"]]. Being the first Viggen variant produced and intended to replace the [[A32A]], the {{PAGENAME}} offers the air-to-ground capability that the later [[JA37C]] lacks.

== General info ==
=== Flight performance ===
{{Specs-Avia-Flight}}


Entering service in 1971, the {{PAGENAME}} is almost 10 years older than the [[JA37C]] found in the fighter line beside it. Despite being almost indistinguishable from each other visually, both aircraft differ heavily in flight performance. The {{PAGENAME}} is noticeably more primitive than its fighter brethren, requiring suspended ordnance to compensate for the lack of internal weapons. This, combined with the weaker powerplant, makes the {{PAGENAME}} feel a lot heavier when fully kitted out. Despite this, the performance is not something to underestimate, as the Viggen platform still offers almost unmatched 'jack of all trades' performance, with excellent manoeuvrability, acceleration, and top speed.
[[File:AJ37 Scenery.png|left|537x537px|AJ37 viewed from behind, making a right turn.|thumb]]
For better or worse, flying the {{PAGENAME}} is comparable to the Draken family of fighters preceding it. The overall flight performance is so extreme that most opponents the {{PAGENAME}} comes across cannot keep up with it. But a trade-off is still the lack of significant energy retention. When flown recklessly, the {{PAGENAME}} has a hard time keeping its speed up, which can be exploited by more powerful opponents. However, an opponent that does commit to these low speeds is likely to lose due to the low-speed handling of the Viggen. All variants, including the {{PAGENAME}}, come fit with flap systems designed to push air under the main wing, allowing the aircraft to manoeuvre efficiently even when stalling. Because of this, dogfighting often comes down to managing your speed, and ensuring that your manoeuvrability is better than your opponent's, either by forcing an overshoot, or baiting them into committing to a low-speed engagement.

=== Survivability and armour ===
{{Specs-Avia-Armour}}

Although designed with air-to-ground missions in mind, the {{PAGENAME}} does not come equipped with pilot protection. Despite its size, the {{PAGENAME}} is not well-suited for handling incoming damage. The fuselage is noticeably tanky, but due to the large engine and control surfaces, the likelihood of surviving hits without consequence is fairly small.

{{main|m/71 (120 kg)|psrak m/70|Akan m/55 (30 mm)}}
{{main|RB24|RB24J|RB 75|Rb05A}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 2 x 30 mm Akan m/55 cannons (150 rpg = 300 total)
* 2 x RB24J missiles

The two stock loadouts on the {{PAGENAME}} allow for either two gun pods, or two RB24J missiles. The performance of the RB24J often allows two guaranteed air kills, which can be important when spading the aircraft. However, more skilled pilots might find more use out of the Akan gun pods as they can down significantly more aircraft in one go and still engage ground targets if needed. They can be somewhat tricky to get used to, however, as they are spaced out from the center of the aircraft, both horizontally and vertically.

* 24 x psrak m/70 rockets
* 12 x psrak m/70 rockets + 48 x countermeasures

[[File:AJ37 Countermeasures.png|thumb|410x410px|AJ37 dispensing countermeasures]]
The m/70 rockets are the only air-to-ground ordnance shared with the JA37C. The rockets allow for great precision attacks from far range thanks to the ballistic computer, and due to the large explosive filler, a single accurate hit is more than enough to deal with any armoured threat. The rocket placement can be somewhat tricky as they are not centred with the aircraft, similar to the gun pods.

* 2 x Rb05A missiles
* 2 x Rb05A missiles + 48 x countermeasures

The Rb05A is unique in its class, as this manually guided air-to-ground missile features a proximity fuze for attacking airborne threats. Although very unconventional to use, this missile is highly potent in ground battles, as the explosive can kill any tank it hits, while also destroying helicopters with ease if needed.

* 2 x RB 75 missiles

The RB 75 is identical to the [[AGM-65A]] found on other aircraft and performs equally well. This air-to-ground missile uses optical guidance to distinguish targets, allowing it to guide itself after launch. Since the missile is capable of gliding up to 20 km of distance, altitude is preferred when deploying for the best distance and target visibility. When employed correctly, the {{PAGENAME}} can safely stay away from SAM systems while engaging ground vehicles.

* 48 x countermeasures + 2 x RB 75 missiles
* 48 x countermeasures + 2 x RB24 missiles
* 48 x countermeasures + 2 x RB24J missiles

The countermeasures used by the {{PAGENAME}} are carried in two pods, one on each wing. Both come equipped with 24 slots each, dispensing in unison when activated. These flares require some manoeuvring and throttle management to deploy efficiently, especially since the direction they dispense is straight behind the nozzle. Cutting afterburner and banking slightly is always optimal when flaring, and will throw off most heat-seeking missiles.

* 16 x 120 kg m/71 bombs (1,920 kg total)
* 8 x 120 kg m/71 bombs + 48 x countermeasures (960 kg total)

[[File:AJ37 bombs.png|thumb|410x410px|AJ37 bombing targets]]
The 120 kg m/71s are the only type of bombs found on this aircraft. Carried in groups of four, these bombs are dispensed singularly starting from the left. Their limited explosive mass makes them fairly inefficient at destroying bases in air battles. However, the precision offered by the ballistic computer allows for plenty of stopping power against ground vehicles. These bombs are also a lot safer to use than unguided rockets, as they do not require the pilot to look directly at the target.

* 2 x 30 mm Akan m/55 cannons + 2 x Rb05A missiles
* 2 x 30 mm Akan m/55 cannons + 2 x RB 75 missiles
* 2 x 30 mm Akan m/55 cannons + 12 x psrak m/70 rockets
* 2 x 30 mm Akan m/55 cannons + 2 x RB24J missiles
* 2 x 30 mm Akan m/55 cannons + 2 x RB24 missiles

The Akan-paired loadouts give a lot more flexibility when engaging both ground and air targets. The RB24J missiles paired with the 30 mm Akan pods is the most optimal setup for air battles, as it essentially combines the two stock loadouts found early on.

== Usage in battles ==


'''Air Realistic Battles'''

* Use flares when uptiered
* Always carry RB24J missiles
* Take as much fuel as possible
* Avoid higher altitudes
* Stay as fast as possible when engaging aircraft

[[File:AJ37 Climb.png|thumb|540x540px|AJ37 seen climbing]]
The {{PAGENAME}} has no limitations when it comes to flight performance. The acceleration, manoeuvrability, and top speed outclasses almost any aircraft it faces, giving it plenty of wiggle room for engaging anything it wants. The downside lies in the suspended weaponry, which is very limited for a plane its size. Being unable to carry more than two missiles, and having to choose between countermeasures or gun pods makes engaging air targets in this aircraft troublesome. These downsides are entirely dependent on the opponents a pilot is going against, as some aircraft might have even less to work with than the {{PAGENAME}}, making them easy prey. In downtiers, the {{PAGENAME}} can become unstoppable as the armament becomes secondary. Since the {{PAGENAME}} is one of the best handling supersonic aircraft, facing subsonic and transonic opponents is a walk in the park. When facing these sorts of aircraft, firepower should always be prioritized to maximize the amount of damage the plane can put out. Here, a pilot should focus on going straight in, keeping opponents busy for allied teammates.

When facing more potent opponents, however, especially those at higher tiers, the lacklustre weaponry becomes apparent. The {{PAGENAME}} carries half the expected amount of missiles and has no all-aspect capability. On top of this, opponents at this tier often carry potent missiles that require flares to properly avoid. This forces a decision to be made before battle. Since the {{PAGENAME}} is unable to carry flares and guns simultaneously, a pilot has to decide between having better defensive options, or more offensive capability. This often boils down to pilot skill and playstyle, as flying around without countermeasures requires careful planning and split-second decision-making to avoid incoming missiles. In these matches, especially when playing without flares, the {{PAGENAME}} should stay behind teammates, flanking towards the sides in hope of catching opponents off-guard or by themselves.

'''Ground Realistic Battles'''

* Use countermeasures when facing SAM systems
* Use suspended weaponry of your choice
* Gain altitude quickly when using RB 75
* Stay as low and fast as possible when using rockets, bombs, cannons, or the Rb05As

Using the AJ37 for its intended purpose can sometimes be trickier than fighting aircraft, especially due to the prominent threat of SAM systems. The AJ37 is much more potent compared to the earlier [[A32A]] in almost every regard, but that does not make it immune to anti-air equipment. The best way to counter SAM systems is by flying at high speeds while deploying chaff simultaneously. This forces radar locks to reset, allowing for short timeframes of efficient ground striking. Staying above Mach is almost a requirement, unless terrain can be worked with to avoid sightlines with the SAM launcher. A more daring tactic is to forego countermeasures altogether, and focusing on destroying the SAM system before it even locates the aircraft. This allows for more variety in the suspended ordnance, doubling the number of bombs or rockets, or allowing the use of Akans to combat air targets at the same time.

This mentality does not apply when using the RB 75, as this missile allows for much further distance when engaging. With over 20 km of launch range, the Maverick missile is able to stay out of the range of ground-based SAM equipment, while still engaging ground targets. The optimal strategy here is to gain altitude directly after spawning, trying to separate a great distance from the battlefield. A great way to check for optimal distance is watching the capture-point marker that tells distance, as it gives a rough estimate of your current range. When beyond 12 km, the average distance a SAM system can reach, a pilot can begin checking for targets on the ground through the sight. Once a target is acquired, turn back and repeat the process. Due to the limited armament, it can be quite handy to carry a second ordnance option or to simply climb near the airfield for quick rearming.

{{Notice|Remember to check for helicopters when using the Rb05A missile! The proximity fuze allows for them to be easily taken down.}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish strike aircraft {{Battle-rating}}. It was introduced in [[Update "Ground Breaking"]]. Being the first Viggen variant produced and intended to replace the [[A32A]], the {{PAGENAME}} offers the air-to-ground capability that the later [[JA37C]] lacks.

== General info ==
=== Flight performance ===
{{Specs-Avia-Flight}}


Entering service in 1971, the {{PAGENAME}} is almost 10 years older than the [[JA37C]] found in the fighter line beside it. Despite being almost indistinguishable from each other visually, both aircraft differ heavily in flight performance. The {{PAGENAME}} is noticeably more primitive than its fighter brethren, requiring suspended ordnance to compensate for the lack of internal weapons. This, combined with the weaker powerplant, makes the {{PAGENAME}} feel a lot heavier when fully kitted out. Despite this, the performance is not something to underestimate, as the Viggen platform still offers almost unmatched 'jack of all trades' performance, with excellent manoeuvrability, acceleration, and top speed.
[[File:AJ37 Scenery.png|left|frame|532x532px|AJ37 viewed from behind, making a right turn.]]
For better or worse, flying the {{PAGENAME}} is comparable to the Draken family of fighters preceding it. The overall flight performance is so extreme that most opponents the {{PAGENAME}} comes across cannot keep up with it. But a trade-off is still the lack of significant energy retention. When flown recklessly, the {{PAGENAME}} has a hard time keeping its speed up, which can be exploited by more powerful opponents. However, an opponent that does commit to these low speeds is likely to lose due to the low-speed handling of the Viggen. All variants, including the {{PAGENAME}}, come fit with flap systems designed to push air under the main wing, allowing the aircraft to manoeuvre efficiently even when stalling. Because of this, dogfighting often comes down to managing your speed, and ensuring that your manoeuvrability is better than your opponent's, either by forcing an overshoot, or baiting them into committing to a low-speed engagement.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish strike aircraft {{Battle-rating}}. It was introduced in [[Update "Ground Breaking"]]. Being the first Viggen variant produced and intended to replace the [[A32A]], the {{PAGENAME}} offers the air-to-ground capability that the later [[JA37C]] lacks.

== General info ==
=== Flight performance ===
{{Specs-Avia-Flight}}


Entering service in 1971, the {{PAGENAME}} is almost 10 years older than the [[JA37C]] found in the fighter line beside it. Despite being almost indistinguishable from each other visually, both aircraft differ heavily in flight performance. The {{PAGENAME}} is noticeably more primitive than its fighter brethren, requiring suspended ordnance to compensate for the lack of internal weapons. This, combined with the weaker powerplant, makes the {{PAGENAME}} feel a lot heavier when fully kitted out. Despite this, the performance is not something to underestimate, as the Viggen platform still offers almost unmatched 'jack of all trades' performance, with excellent manoeuvrability, acceleration, and top speed.

For better or worse, flying the {{PAGENAME}} is comparable to the Draken family of fighters preceding it. The overall flight performance is so extreme that most opponents the {{PAGENAME}} comes across cannot keep up with it. But a trade-off is still the lack of significant energy retention. When flown recklessly, the {{PAGENAME}} has a hard time keeping its speed up, which can be exploited by more powerful opponents. However, an opponent that does commit to these low speeds is likely to lose due to the low-speed handling of the Viggen. All variants, including the {{PAGENAME}}, come fit with flap systems designed to push air under the main wing, allowing the aircraft to manoeuvre efficiently even when stalling. Because of this, dogfighting often comes down to managing your speed, and ensuring that your manoeuvrability is better than your opponent's, either by forcing an overshoot, or baiting them into committing to a low-speed engagement.

=== Survivability and armour ===
{{Specs-Avia-Armour}}

Although designed with air-to-ground missions in mind, the {{PAGENAME}} does not come equipped with pilot protection. Despite its size, the {{PAGENAME}} is not well-suited for handling incoming damage. The fuselage is noticeably tanky, but due to the large engine and control surfaces, the likelihood of surviving hits without consequence is fairly small.

=== Suspended armament ===

{{main|m/71 (120 kg)|psrak m/70|Akan m/55 (30 mm)}}
{{main|RB24|RB24J|RB 75|Rb05A}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 2 x 30 mm Akan m/55 cannons (150 rpg = 300 total)
* 2 x RB24J missiles

The two stock loadouts on the {{PAGENAME}} allow for either two gun pods, or two RB24J missiles. The performance of the RB24J often allows two guaranteed air kills, which can be important when spading the aircraft. However, more skilled pilots might find more use out of the Akan gun pods as they can down significantly more aircraft in one go and still engage ground targets if needed. They can be somewhat tricky to get used to, however, as they are spaced out from the center of the aircraft, both horizontally and vertically.

* 24 x psrak m/70 rockets
* 12 x psrak m/70 rockets + 48 x countermeasures

The m/70 rockets are the only air-to-ground ordnance shared with the JA37C. The rockets allow for great precision attacks from far range thanks to the ballistic computer, and due to the large explosive filler, a single accurate hit is more than enough to deal with any armoured threat. The rocket placement can be somewhat tricky as they are not centred with the aircraft, similar to the gun pods.

* 2 x Rb05A missiles
* 2 x Rb05A missiles + 48 x countermeasures

The Rb05A is unique in its class, as this manually guided air-to-ground missile features a proximity fuze for attacking airborne threats. Although very unconventional to use, this missile is highly potent in ground battles, as the explosive can kill any tank it hits, while also destroying helicopters with ease if needed.

* 2 x RB 75 missiles

The RB 75 is identical to the [[AGM-65A]] found on other aircraft and performs equally well. This air-to-ground missile uses optical guidance to distinguish targets, allowing it to guide itself after launch. Since the missile is capable of gliding up to 20 km of distance, altitude is preferred when deploying for the best distance and target visibility. When employed correctly, the {{PAGENAME}} can safely stay away from SAM systems while engaging ground vehicles.

* 48 x countermeasures + 2 x RB 75 missiles
* 48 x countermeasures + 2 x RB24 missiles
* 48 x countermeasures + 2 x RB24J missiles

The countermeasures used by the {{PAGENAME}} are carried in two pods, one on each wing. Both come equipped with 24 slots each, dispensing in unison when activated. These flares require some manoeuvring and throttle management to deploy efficiently, especially since the direction they dispense is straight behind the nozzle. Cutting afterburner and banking slightly is always optimal when flaring, and will throw off most heat-seeking missiles.

* 16 x 120 kg m/71 bombs (1,920 kg total)
* 8 x 120 kg m/71 bombs + 48 x countermeasures (960 kg total)

The 120 kg m/71s are the only type of bombs found on this aircraft. Carried in groups of four, these bombs are dispensed singularly starting from the left. Their limited explosive mass makes them fairly inefficient at destroying bases in air battles. However, the precision offered by the ballistic computer allows for plenty of stopping power against ground vehicles. These bombs are also a lot safer to use than unguided rockets, as they do not require the pilot to look directly at the target.

* 2 x 30 mm Akan m/55 cannons + 2 x Rb05A missiles
* 2 x 30 mm Akan m/55 cannons + 2 x RB 75 missiles
* 2 x 30 mm Akan m/55 cannons + 12 x psrak m/70 rockets
* 2 x 30 mm Akan m/55 cannons + 2 x RB24J missiles
* 2 x 30 mm Akan m/55 cannons + 2 x RB24 missiles

The Akan-paired loadouts give a lot more flexibility when engaging both ground and air targets. The RB24J missiles paired with the 30 mm Akan pods is the most optimal setup for air battles, as it essentially combines the two stock loadouts found early on.

== Usage in battles ==


'''Air Realistic Battles'''

* Use flares when uptiered
* Always carry RB24J missiles
* Take as much fuel as possible
* Avoid higher altitudes
* Stay as fast as possible when engaging aircraft

The {{PAGENAME}} has no limitations when it comes to flight performance. The acceleration, manoeuvrability, and top speed outclasses almost any aircraft it faces, giving it plenty of wiggle room for engaging anything it wants. The downside lies in the suspended weaponry, which is very limited for a plane its size. Being unable to carry more than two missiles, and having to choose between countermeasures or gun pods makes engaging air targets in this aircraft troublesome. These downsides are entirely dependent on the opponents a pilot is going against, as some aircraft might have even less to work with than the {{PAGENAME}}, making them easy prey. In downtiers, the {{PAGENAME}} can become unstoppable as the armament becomes secondary. Since the {{PAGENAME}} is one of the best handling supersonic aircraft, facing subsonic and transonic opponents is a walk in the park. When facing these sorts of aircraft, firepower should always be prioritized to maximize the amount of damage the plane can put out. Here, a pilot should focus on going straight in, keeping opponents busy for allied teammates.

When facing more potent opponents, however, especially those at higher tiers, the lacklustre weaponry becomes apparent. The {{PAGENAME}} carries half the expected amount of missiles and has no all-aspect capability. On top of this, opponents at this tier often carry potent missiles that require flares to properly avoid. This forces a decision to be made before battle. Since the {{PAGENAME}} is unable to carry flares and guns simultaneously, a pilot has to decide between having better defensive options, or more offensive capability. This often boils down to pilot skill and playstyle, as flying around without countermeasures requires careful planning and split-second decision-making to avoid incoming missiles. In these matches, especially when playing without flares, the {{PAGENAME}} should stay behind teammates, flanking towards the sides in hope of catching opponents off-guard or by themselves.

'''Ground Realistic Battles'''

* Use countermeasures when facing SAM systems
* Use suspended weaponry of your choice
* Gain altitude quickly when using RB 75
* Stay as low and fast as possible when using rockets, bombs, cannons, or the Rb05As

Using the AJ37 for its intended purpose can sometimes be trickier than fighting airplanes, especially due to the prominent threat of SAM systems. The AJ37 is much more potent compared to the earlier A32A in almost every regard, but that does not make it immune to Anti-Air equipment. The best way to counter SAM systems is by flying at high speeds while deploying chaff simultaneously. This forces radar locks to reset, allowing for short timeframes of efficient ground striking. Staying above mach is almost a requirement, unless terrain can be worked with to avoid sightline with the SAM launcher. A more daredevilish tactic is foregoing countermeasures altogether, and focusing on destroying the SAM system before it even locates the aircraft. This allows for more variety in the suspended ordinance, doubling the number of bombs or rockets, or allowing the use of Akans to combat air targets at the same time.

This sort of mentality does not apply to using the RB 75, as this missile allows for much further distance when engaging. With over 20km of launch range, the Maverick missile is able to stay out of range from ground-based SAM equipment, while still engaging ground targets. The optimal strategy here is to gain altitude directly after spawning, trying to separate a great distance from the battlefield. A great way to check for optimal distance is watching the capture-point marker that tells distance, as it gives a rough estimate of your current range. When beyond 12km, the average distance a SAM system can reach, a pilot can begin checking for targets on the ground through the sight. Once a target is acquired, turn back and repeat the process. Due to the limited armament, it can be quite handy to carry a second ordinance option or to simply climb near the airfield for quick rearming.

{{Notice|Remember to check for helicopters when using the Rb05A missile! The proximity fuze is often a guaranteed kill against them.}}

Since the missile is capable of gliding up to 20 km of distance, altitude is preferred when deploying for the best distance and target visibility. When employed correctly, the {{PAGENAME}} can safely stay away from SAM systems while engaging ground vehicles.

* 48 x countermeasures + 2 x RB 75 missiles
* 48 x countermeasures + 2 x RB24 missiles
* 48 x countermeasures + 2 x RB24J missiles

The countermeasures used by the {{PAGENAME}} are carried in two pods, one on each wing. Both come equipped with 24 slots each, dispensing in unison when activated. These flares require some maneuvering and throttle management to deploy efficiently, especially since the direction they dispense is straight behind the nozzle. Cutting afterburner and banking slightly is always optimal when flaring, and will throw off most heat-seeking missiles.

* 16 x 120 kg m/71 bombs (1,920 kg total)
* 8 x 120 kg m/71 bombs + 48 x countermeasures (960 kg total)

The 120kg m/71s are the only type of bombs found on this aircraft. Carried in groups of four, these bombs are dispensed singularly starting from the left. Their limited explosive mass makes them fairly inefficient at destroying bases in air battles. However, the precision offered by the ballistics computer allows for plenty of stopping power against ground vehicles. These bombs are also a lot safer to use than unguided rockets, as they do not require the pilot to look directly at the target.

* 2 x 30 mm Akan m/55 cannons + 2 x Rb05A missiles
* 2 x 30 mm Akan m/55 cannons + 2 x RB 75 missiles
* 2 x 30 mm Akan m/55 cannons + 12 x psrak m/70 rockets
* 2 x 30 mm Akan m/55 cannons + 2 x RB24J missiles
* 2 x 30 mm Akan m/55 cannons + 2 x RB24 missiles

The Akan-paired loadouts give a lot more flexibility when engaging both ground and air targets. The Rb24J missiles paired with the 30mm Akan pods is the most optimal setup for air battles, as it essentially combines the two stock loadouts found early on.

== Usage in battles ==

'''Air Realistic Battles'''

* Use flares when uptiered
* Always carry Rb24J missiles
* Take as much fuel as possible
* Avoid higher altitudes
* Stay as fast as possible when engaging aircraft

The {{PAGENAME}} has no limitations when it comes to flight performance. The acceleration, maneuverability, and top speed outclasses almost any aircraft it faces, giving it plenty of wiggle room for engaging anything it wants. The downside lies in the suspended weaponry, which is very limited for a plane its size. Being unable to carry more than two missiles, and having to choose between countermeasures or gun pods makes engaging air targets in this aircraft troublesome. These downsides are entirely dependent on what aircraft a pilot is going against, as some airplanes might have even less to work with than the {{PAGENAME}}, making them easy prey. In downtiers, the {{PAGENAME}} can become unstoppable as the armament becomes secondary. Since the {{PAGENAME}} is one of the best handling supersonic aircraft, facing subsonic and transonic opponents is a walk in the park. When facing these sorts of aircraft, firepower should always be prioritized to maximize the amount of damage the plane can put out. Here, a pilot should focus on going straight in, keeping opponents busy for allied teammates.

When facing more potent opponents, however, especially those at higher tiers, the lackluster weaponry becomes apparent. The {{PAGENAME}} carries half the expected amount of missiles and has no all-aspect capability. On top of this, opponents at this tier often carry potent missiles that require flares to properly avoid. This forces a decision to be made before battle. Since the {{PAGENAME}} is unable to carry flares and guns simultaneously, a pilot has to decide between having better defensive options, or more offensive capability. This often boils down to pilot skill and playstyle, as flying around without countermeasures requires careful planning and split-second decision-making to avoid incoming missiles. In these matches, especially when playing without flares, the {{PAGENAME}} should stay behind teammates, flanking towards the sides in hope of catching opponents off-guard or by themselves.

'''Ground Realistic Battles'''

* Use suspended weaponry of your choice
* Use countermeasures when facing SAM systems
* Gain altitude quickly (RB 75)
* Stay as low and fast as possible (Arak., Akan., Bombs, Rb05A)

== History ==

'''Background'''

During the 1960s advances in technology occurred rapidly alongside the aviation industry, paving way for more complex and capable designs. In order to keep up with the rest of the industry, SAAB had to develop aircraft at a constant pace, often coming up with replacements before the predecessor had even entered service. The SAAB Viggen was sought to be the replacer for the A32A and was being considered as early as 1952. The decision of whether to make a fighter or attacker design continued for years. By the end of the 50s, project 1500 started to show potential, with a delta wing design capable of performing multiple roles through different versions. The wing design would allow for short-distance take-off and landings, following the BAS60 roadbase system requirements. These also included all-weather capability and full coverage of the 2000km Swedish coastline.

The 37-1 prototype took to the skies in February of 1967. The design still had to go through extensive modifying before the plane could reach the production line. The canards were angled, the wing adjusted, and the fuselage bent slightly. Many of the unorthodox appearances of the Viggen arrived from the extensive testing done on the first prototypes. When finalized, an order of AJ37 Viggens was handed over to F7 Skaraborg, becoming the first division utilizing the aircraft.

'''JA37'''
[[File:JA37 Prototype.jpg|thumb|333x333px|JA37 Prototype airborne, carrying Rb71 Skyflash missiles.]]
With the Viggen successfully replacing aging attack and reconnaissance aircraft, the focus shifted towards the replacement of the J35 Draken. This required extensive modifying of the Viggen as a whole, as the requirements for an interceptor, wouldn’t be met with the powerplant and avionics used in the already existing variants. The project was extensive, redesigning most areas of the plane to fit these specifications. SAAB had to fit an internal gun, an air-to-air radar, a new flight computer, which allowed a real-time data-feed between ground stations and flight groups. One of the more complicated adjustments was the powerplant, where the engineers had to install an additional fan stage. This helped counteract the compressor stall the RM8 engine often experienced at high angles of attack, allowing the JA37 to dogfight more comfortably. These modifications were expensive, exceeding the set budget several times. But SAAB pressed on with the design until the version was fully developed.

The first completed JA37 flew on November 4th, 1977. The first service variants were delivered to F13 Bråvalla in June of 1980, while F17 Blekinge and F21 Luleå received theirs in 1981 and 1982 respectively. The JA37 would go on to be the most produced variant of the Viggen, with 147 aircraft delivered between eight different divisions. The JA37 was highly appreciated by those who flew it, and saw many modifications that extended its lifespan.

'''JA37C'''

As the 80s came to an end, the Viggen platform began to require an overhaul to bring the capabilities closer to that of other countries. The Gripen project was still years away from being completed, so an upgrade program began that would involve all JA37 in continued service being upgraded to the JA37C standard. This package introduced countermeasures, and a new signal processor, allowing the radar to track more efficiently against enemy jamming. The radar could now follow multiple targets simultaneously and also display virtual targets to enhance pilot training. This variant of the JA37 would see use up until the end of the decade, still being a capable platform for its time.

=== [[wt:en/news/7304-development-perfect-interceptor-ja37c-jaktviggen-and-premium-j35a-draken-en|Devblog]] ===
The requirements for a new aircraft with very high performance to replace the SAAB 35 Draken emerged in the early 1960s. In 1962, the design team of the SAAB company prepared a draft design of the SAAB 37 aircraft, built according to an exotic double delta wing. The project seemed interesting for military authorities , and SAAB received funding to fully develop a new fighter in four basic configurations. The last and most advanced version was the SAAB JA37 Jaktviggen fighter-interceptor, the development of which continued until the mid-1970s, which was associated with the improvement of the engine and the development of modern electronic equipment. The first flight of the experimental JA37 interceptor fighter took place in June 1974, and in 1979 the fighter began to be supplied for service. Until 1990, 149 JA37 Jaktviggen units were produced. The specific appearance made the aircraft of the J37 family a “calling card” of the Royal Swedish Air Force for a long time.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].

The J29F is the final variant of the J29 "Tunnan" family, combining excellent engine performance, and manoeuvrability for a well-rounded fighter at its battle rating. It is the only J29 able to be outfitted with the [[Rb24]] air-to-air missiles.

== General info ==
=== Flight performance ===
{{Specs-Avia-Flight}}


The J29F will come off as heavy and quite sluggish for any pilots new to the plane. But when the J29F gets upgraded with suspended armaments and better performance, the plane starts to feel a bit more capable. The superior roll rate and vertical energy come in handy in many situations, and with two Rb24 air-to-air missiles, the J29F becomes a threat to most enemies in the sky. The J29F can be described as a "Jack of all trades" in many areas. Even if the J29F is outclassed in every area by some vehicle, a pilot who knows their enemies will find a way to outperform them in this plane. Players with previous experience in the [[J29A]] or [[J/A29B]] will most likely find the new afterburner a welcome upgrade to the vehicle. The RM2B engine carries this plane in any direction the pilot wishes and significantly improves the acceleration. However, just like all the other J29 variants, the J29F suffers from bad defensive capabilities. While many opponents find it easy to get rid of people behind them, the J29F has a hard time both losing energy and maneuvering in different directions. This makes it difficult to get rid of opponents following close behind, which should always be taken into consideration when planning an attack.

=== Survivability and armour ===
{{Specs-Avia-Armour}}


[[File:Protection J29F.png|thumb|Armour found inside the J29F.]]
The J29F is outfitted with 3 armour plates spread out in different areas of the plane. The most important of which being the bulletproof glass of 64mm, which will save the pilots' life in most headons. The J29F is quite strong in terms of survivability, being able to tank a lot of low-caliber shells without much damage. This can help a J29F pilot stay in battle far longer than usual, or return to base safely. It is important, however, to avoid incoming damage since surviving incoming shells should never be expected as "survivable". Many shells will set the J29F on fire, knock out its engine, and destroy the tail section. All of which will by themselves put the J29F out of combat.

=== Offensive armament ===
{{Specs-Avia-Offensive}}

{{main|Akan m/47C (20 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 20 mm Akan m/47C cannons, chin-mounted (180 rpg = 720 total)

The firepower is the same as on all the other J29 variants found in the tech tree. The Swedish Akan m/49C is a somewhat potent 20 mm cannon that is comparable to the AN/M3 cannons found on the F9F-8. This gun can be experienced as weak when compared to 30 mm revolver cannons found at the same battle rating. But despite requiring a longer gun time, the high ammo count of 720 rounds will significantly help people who feel less comfortable with their aim.

=== Suspended armament ===
{{Specs-Avia-Suspended}}

{{main|RB24|srak m/55 Frida}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 24 x 7,5 cm srak m/55 Frida rockets
* 2 x RB24 missiles

== Usage in battles ==


==== Fighting different enemies ====
In Realistic Battles, the J29F is similar in playstyle to that of a [[MiG-15bis]], while still sharing some similarities to the [[F-86F-25|F-86F-25 Sabre.]] A J29F keeps energy very well when the afterburner is used, giving it a strong rate of climb and acceleration. This means the J29F can easily energy fight most enemies it encounters. However, the J29F should never be seen as a one-trick pony. When coming face-to-face against stronger and faster opponents, energy tactics can no longer be used. In that case, it can be better to use the superior turn- and roll-rate, to avoid incoming attacks from above. If missiles are researched, these enemies will most likely be forced to leave you alone since they have a hard time dodging the 10g pull of the Rb24.

It is very important to know your enemies when using the J29F, to apply the right tactics against them. It is strongly recommended to look up the strengths and weaknesses of different opponents it may face. The J29F is never the strongest in any area but is always better than its enemy in one or two areas, which should always be exploited.

==== Using the Rb24 ====
The J29F is the only J29 "Tunnan" equipped with air-to-air missiles. The Rb24 is a license-built variant of the American Aim-9B missile. This missile is one of the key upgrades the J29F can use to its advantage. The Rb24 is quite slow when it comes to launching, and tracks enemies quite poorly. Despite this, the missile forces faster opponents to extend, and unaware opponents to combust. The missile gives the J29F more ways to deal with enemies, at a slight performance cost.

When using these missiles in battle, it can be useful to go for a Side-rushing strategy. This will put the plane in a superior energy situation if combined with climbing. This strategy helps the missile the most since it lets the J29F appear behind enemies, to launch the Rb24 when they're busy. It can also be important to get rid of the suspended armament as soon as possible, to improve the overall flight performance. Missiles shouldn't be wasted, however, since they help in dealing with faster targets. The Rb24 isn't very good at turning but can easily eliminate fighters climbing upwards, or those travelling at slow speeds. The optimal launch distance for the Rb24 is between 1 - 3 kilometers.

==== Rushing ====
In Realistic Battles, a fairly common strategy is the so-called "rush" strategy. During a rush, a jet pilot will maximize speed rather than altitude, trying to intercept enemy players who won't expect them. The rush strategy can be used in the J29F to a certain degree. Since the J29F has an average top speed, getting to the enemy team can be done quite swiftly. It's however, still recommended to gain some altitude since speed won't be lost when pushing the plane slightly upwards.

The rush strategy can allow a J29F pilot to easily shoot down planes who don't expect it and works wonders when paired with some altitude. The only downside is that the J29F might be attacked by an overwhelming amount of enemies, forcing the J29F to play defensively. This is why the Rush strategy is recommended to pilots who have friends or teammates to back them up since it's very difficult to win a defensive situation.

==== Side-rushing ====
A more effective strategy in Realistic Battles is a side rushing strategy. This strategy is executed the same way as the rush strategy, except the jet is flown more towards the side, giving you extra time to gain speed. The J29F has no problem accelerating but dislikes being forced into a defensive situation. This strategy can be paired with a slight altitude gain to put the J29F in a superior position. Although the J29F won't be the first one to the battlefield, it will be able to down more planes by keeping people away from its back. A pilot should still be aware of his/her surroundings, in case the enemy decides to take a similar route.

The side-rushing strategy also improves the usefulness of the Rb24 air-to-air missiles. The side-rush can be utilized to end up behind the enemy team, making good use of the Rear-Aspect lock technique. However, these attacks are usually achieved when fighting against unaware players.

=== Pros and cons ===


'''Pros:'''

* Strong energy retention
* Superior roll-rate compared to other jets it faces
* High ammo count
* Fast acceleration
* Tough airframe being able to tank shots
* Two RB24 air-to-air missiles

'''Cons:'''

* Mediocre top speed
* Sluggish tail controls - weak when flown defensively
* Underwhelming firepower - requires more gun time than the J29D
* Short landing gear - becomes difficult to land when damaged
* Tiny air-brakes - Makes it difficult to force an overshoot

== History ==

=== Initial development ===
During WWII, Sweden had effectively fallen behind in the development of military aircraft. This was largely due to a severely underdeveloped aircraft engine industry in Sweden which meant that there were no high-end engines available for aircraft production. Thus Sweden was still projecting propeller-driven fighter aircraft in 1945 equivalent to fighters projected by other nations 1-3 years prior. Since it was obvious by 1945 that jet aircraft was the future the Swedish Air Force decided to immediately scrap all propeller-driven fighter projects and instead make the jump to a jet fighter. Sweden's leading aeronautical firm SAAB, who was already actively working with the Swedish Air Force on the previously mentioned propeller fighters, was tasked with projecting this new jet fighter. Several designs were looked at but by mid-1945 it was decided that a mid-high wing aircraft with a central air intake would be the best option. Due to the mid-high wing it was not possible to house the landing gear in the wings. Instead, it was decided to house the landing gear in the fuselage of the aircraft. This concept got the project name R1001, R standing for "reaktionsmotor" (reaction engine), the Swedish military term for jet engines.

The original specifications for the R1001 called for a radar rangefinder, four Bofors 20 mm akan m/45 cannons mounted in the nose with 180 rounds per gun, external fuel tanks and a top speed of 1,000 km/h. The engine was originally supposed to be an indigenous design by the company STAL but by late 1945 Sweden had gotten the green light for acquiring the new state-of-the-art de Havilland Ghost engine. There are several reasons why Sweden was allowed to buy this engine even before it was finished, but the two main factors were the economic state of Britain after the war and Sweden's good relations with the company de Havilland. The engine was however not the only thing which changed at an early stage. Originally the R1001 featured straight wings, as was common at the time. However, by pure luck Sweden was able to acquire some German WWII research papers from a Swiss source regarding swept wings on aircraft and their increased performance at high speeds. Thus it was decided to change the R1001 design to feature swept wings. The first blueprints of the R1001 featuring swept wings were finished by late 1945 and within 3 years a prototype had been constructed and was ready for flight testing. During these 3 years the design would change even further from the original concept. The radar rangefinder was dropped for unknown reasons, and the Bofors cannons were switched for Hispano designs due to delays at Bofors. By 1947 the aircraft had also received the designation J29.

=== Testing and production ===
The J29 prototype flew for the first time on the 1st of September 1948 and immediately showed incredible performance. The pilot chosen for this flight was SAAB's test pilot at the time, an Englishmen by the name Robert A. "Bob" Moore. He was a British squadron leader with previous experience flying jets and was thus suitable for the tests. The test flight lasted for half an hour and after a successful landing, Moore stated that "on the ground, it's an ugly duckling, but in the air it's a swift." Like many aircraft which pick up a nickname due to a specific feature or shape, the J29 would fairly quickly receive the nickname "Flygande Tunnan" (The Flying Barrel) or just "Tunnan" (The Barrel) for short. Initially thought of as degrading, the nickname Tunnan would not only become the official name for the aircraft but would also start the SAAB tradition of naming their combat aircraft, a tradition which persists to this day.

After correcting a few production errors the prototype would not only achieve the specified top speed of 1,000 km/h but it would even surpass it, achieving a sustainable speed of 1,060 km/h at one point. The design of the J29 showed a lot of promise for the future and talk of future variants would begin even before production had started. In fact, just a month after the prototype had taken to the air, there was talk of implementing attack-rockets and deflatable internal fuel tanks.

Production of the first J29 variant, the J29A, would commence in 1950 and deliveries to the air force would start in early 1951. It was quickly realized that the internal fuel capacity of the J29A was too limited and work began on implementing the previously discussed internal deflatable fuel tanks. This would be realized in a new version of the J29, designated [[J/A29B|J29B]], which entered production and service in 1953. The J29B's new internal fuel tanks gave it a 50% increase in fuel capacity compared to the J29A. The J29B would be followed by an unarmed reconnaissance version called the S29C which had been planned at an early stage. The S29C was to be followed by the [[J29D]], featuring increased armament and an afterburner, but due to a variety of reasons the J29D never entered production. Instead, a modified version of the J29B, called the J29E, would enter service. The E-variant featured a new dog toothed wing which increased maneuverability at high speeds. The J29E was soon followed by the [[J29F]] which was an upgrade-program for 210 J29B and E aircraft, increasing their performance and allowing them to serve throughout the 1960s.

All in all, 661 J29s would be produced for the Swedish Air Force, the largest production run by SAAB ever. The last of these would serve until the late 1970s.

=== Legacy ===
The J29 was a truly historical wonder for its time. After being stranded for the duration of the war, Sweden managed to not only catch up with modern aircraft development in a short amount of time but it was also able to lead jet fighter development in Europe for the time and arguably even into modern times. The J29 was the first swept-wing jet fighter to be mass-produced in Europe and together with the Soviet [[MiG-15]] and American [[F-86A-5|F-86]] it set the bar for how the next generation of fighter aircraft should be. It was extremely fast for its time and actually managed to take home two closed-circuit world speed records during the mid 1950s.

Besides its international legacy, the J29 was the first Swedish-designed aircraft to see combat. In September 1961, as part of the Congo-crisis, five J29Bs were stationed in the Republic of Congo to contribute to a UN peacekeeping mission (ONUC) in the region. This led to the formation of the air wing F 22 which exclusively served in Congo. F 22 was later reinforced by four more J29Bs and two S29C reconnaissance planes in 1962. F 22 would quickly take air superiority in the area which in turn lead to them primarily performing attack-missions during the conflict. No aircraft were lost during the ONUC despite large amounts of ground fire. When the ONUC was terminated in 1964, the aircraft-type had been decommissioned in Sweden and thus it was decided to only send home a select few J29s to Sweden. The majority of the F 22 J29s were blown up on the spot in Congo when the Swedish left the area.

=== J29F ===
[[File:Airborne J29F.jpg|thumb|Airborne J29F from the 15th Air Division]]
The J29F was an upgrade-program spanning from 1956 to 1958, in which 210 [[J/A29B|of the J29B]] and J29E models were upgraded to F-standard. F-standard meant that the aircraft would be equipped with new dog-tooth wings originally introduced on the J29E but also the afterburning engine of the scrapped [[J29D]] project.

The J29F was an important step in prolonging the service life of the J29. Being an aircraft with its roots from 1945, the basic J29 was about to become obsolete by the early 1960s. By upgrading them to F-standard they would still be usable throughout the 1960s. This was increased in 1961 when the J29F was modified to carry [[RB24|RB24B]] (AIM-9B) sidewinder air-to-air missiles, allowing them to attack high altitude bombers from behind. Previously the idea was to attack bombers head-on using 75 mm [[Srak m/55 Frida|srak m/55]] rockets. The J29F came to see service with sidewinders all the way to 1978. It was finally decommissioned in 1978, 27 years after the initial type entered service.

=== Survivability and armour ===
{{Specs-Avia-Armour}}


; Armour

* 64 mm bulletproof canopy windscreen
* 10 mm steel plate behind pilot's seat
* 10 mm steel plate in the nose, in front of pilot

The stout little J/A29B is a sneaky little fighter which might be underestimated during a head-on. A 64 mm bulletproof windscreen is in place, which, since it is sloped, provides 165 mm total protection, allowing the pilot to have a greater chance of survival in a head-on. However, unless highly experienced, pilots should avoid head-ons, especially against aircraft such as the [[Super Mystere B2]] and the [[G.91 YS]] which also feature 30 mm DEFA 552 cannons. Make sure to avoid the B2 as well, as the AA.20 air-to-air guided rockets will make the J/A29B have a hard time standing up to this aircraft.

* 4 x 18 cm hprak m/49 rockets

== Usage in battles ==

The J/A29B is armed with 4 x 20 mm Akan m/47C cannons, but still lack a bit of a punch for a fighter. The J/A29B has a good top speed but its acceleration is not the quickest. Once it has built up speed it can catch most enemy jets that it will face, but having an altitude advantage to dive on the target will help get that extra acceleration to hunt down targets.

Turning with the J/A29B is a bad idea since the plane bleeds speed when turning. Even though the J/A29B is good at turning, it can only do so for a small amount of time, before losing enough speed to be easy target for incoming enemies. The J/A29B's strengths are the Hit & Run tactic also known as Boom & Run. Should the J/A29B be uptiered against 8.7, it will struggle to keep up with the enemy jets but that will make the J/A29B an excellent support fighter: when Allied jets are engaged in combat with the enemy and make that enemy bleed its speed, the J/A29B can swoop in and help the teammate.

When taking off with ordnance in RB and Sim modes you must be careful, the J/A29B struggles to get off the runway; spooling, pressuring your front landing gear right before you engage flaps, and using flaps are all essential for a safe takeoff in this plane.

=== Pros and cons ===


'''Pros:'''

* High speed in a straight line.
* Powerful cannons with decent ammunition pool and access to very good AA belts.
* Good ordnance selection for ground attack.
* Effective airbrake and flaps.
* Great turning ability at speed.
* Good roll rate.
* High quantity of rockets which launch individually.

'''Cons:'''

* Slow acceleration.
* Slow climb rate.
* Relatively large target in Ground Battles for SPAA.
* Struggles to get off the runway with some loads.
* Extremely sluggish turning capability at low speed. Will dump speed when turning also.

All in all, 661 J29s would be produced for the Swedish Air Force, the largest production run by SAAB ever. The last of these would serve until the late 1970s.

=== Legacy ===
The J29 was a truly historical wonder for its time. After being stranded for the duration of the war, Sweden managed to not only catch up with modern aircraft development in a short amount of time but it was also able to lead jet fighter development in Europe for the time and arguably even into modern times.

It was extremely fast for its time and actually managed to take home two closed-circuit world speed records during the mid 1950s.

Besides its international legacy, the J29 was the first Swedish-designed aircraft to see combat. In September 1961, as part of the Congo-crisis, five J29Bs were stationed in the Republic of Congo to contribute to a UN peacekeeping mission (ONUC) in the region. This led to the formation of the air wing F 22 which exclusively served in Congo. F 22 was later reinforced by four more J29Bs and two S29C reconnaissance planes in 1962.

The majority of the F 22 J29s were blown up on the spot in Congo when the Swedish left the area.

=== J/A29B ===
Between 1953 and 1955, SAAB would produce and deliver 361 J29Bs to the Swedish air force. These would come to serve in the Swedish air force up until the early 1960s.

As mentioned previously the J29B was fitted with new internal deflatable fuel tanks and these were located in the inner wings. This gave the J29Bs ~50% more fuel than its older brother the J29A. The J29B could also equip two under wing drop tanks weighing up to 600 kg each, which increased the range even further. Interestingly the drop tanks could also be armed as incendiary bombs via a switch box in the cockpit. Beyond drop tanks the aircraft were also capable of carrying a wide variety of rockets for different missions.

Due to delays with the [[A32A]]-development, the J29B would initially serve as an attack aircraft, being designated as the A29B. While rockets were available for the [[J29A]] it was decided to use the J29B as an attack aircraft due to it being a new aircraft type which could be sent directly to the attack wings. There they would stay until 1957 when the A32A finally entered service. Afterwards, they served as regular fighters under the designation J29B.

In Sweden, the J29B would be used until 1963 when the type was ultimately decommissioned due to being obsolete. However a large sum of J29Bs had by this time been upgraded to J29F standards, and these would serve until 1978.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].

The {{PAGENAME}} is a single-engine jet fighter, that was developed by the Swedish company SAAB in the late 1940s. One of the main design features of this aircraft is its swept-back wings, which was designed after that SAAB had managed to acquire German documents from the war, that proved that swept-back wings were necessary when trying to achieve higher speeds. The {{PAGENAME}} also features a Swedish license-built version of the British de Havilland Ghost engine. The armament consists of four 20 mm akan m/47C, a license built copy of the British Hispano Mk V, but with a lower rate of fire. The first prototype flew in 1948, and the aircraft then proceeded to enter service in the Swedish Air Force, Flygvapnet in 1951. It remained in service until 1962 and never saw any combat use.

The J29A has a great top speed, along with an effective rudder and reasonable roll rate. However, it turns poorly at all speeds, and bleeds energy rapidly when forced to do so. It also does not accelerate well.

=== Survivability and armour ===

{{Specs-Avia-Armour}}

; Armour

* 64 mm bulletproof canopy windscreen
* 10 mm steel plate behind pilot's seat
* 10 mm steel plate in the nose, in front of pilot

The stout little J29A is a sneaky little fighter which might be underestimated during a head-on. A 64 mm bulletproof windscreen is in place, which, since it is sloped, provides 165 mm total protection, allowing the pilot to have a greater chance of survival in a head-on. However, unless highly experienced, pilots should avoid head-ons, especially against aircraft such as the [[Super Mystere B2]] and the [[G.91 YS]] which also feature 30 mm DEFA 552 cannons. Make sure to avoid the B2 as well, as the AA.20 air-to-air guided rockets will make the J29A have a hard time standing up to this aircraft.

{{Specs-Avia-Offensive}}

{{main|Akan m/47C (20 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 20 mm akan m/47C cannons, nose-mounted (180 rpg = 720 total)

== Usage in battles ==

The J29A, also known as the "flying barrel", is armed with 4 x 20 mm Akan m/47C cannons that perform well, but still lack a bit of a punch for a fighter. The J29A has a good top speed but acceleration is not the quickest. Once it has built up speed it can catch most enemy jets that it will face, but something that will help it greatly in doing so is having an altitude advantage to dive on the target to get that extra acceleration to hunt down targets.

Turning with the J29A is a bad idea since the plane loves to bleed speed when turning, even though the J29A is good at turning, it can only do so for a small amount of time, before losing enough speed to be easy target for incoming enemies. The J29A's strengths are the Hit & Run tactic also known as Boom n Zoom. Should the J29A be uptiered against 8.7, it will struggle to keep up with the enemy jets but that will make the J29A into an excellent support fighter: when allied jets are engaged in combat with the enemy and make that enemy bleed its speed, the J29A can swoop in and help the teammate.

When taking off in RB and Sim modes you must be careful, J29A struggles to get off the runway, spooling, pressuring your front landing gear right before you engage flaps, and using flaps are all essential to a safe takeoff in this plane.

'''Enemies to be aware of:'''

* [[Swift F.1]]/[[Swift F.7|F.7]]
* [[La-200]]
* [[F-84F]] (all nations)
* [[MiG-15bis]]
* [[F-86 Sabre (Family)|F-86 Sabre]]

When facing these enemies and you see them from distance it's great to take note of any close teammates to help the J29A stand a chance to not be Boom-n-Zoomed, this is why flying with a squadmate that is in a more dogfight-suitable aircraft is highly recommended to make the most out of the J29A, as they will often be able to setup a target for the J29A's Boom-n-Zoom runs.

=== Pros and cons ===


'''Pros:'''

* Decent cannons with plenty of ammunition
* Can turn well at speed
* High max speed

'''Cons:'''

* Inadequate versus its opponents at 8.7 which it faces often
* Very sluggish acceleration
* Dumps speed in turns
* Rudder locks up at higher speeds

== History ==

=== Initial development ===
During WWII, Sweden had effectively fallen behind in the development of military aircraft. This was largely due to a severely underdeveloped aircraft engine industry in Sweden which meant that there were no high-end engines available for aircraft production. Thus Sweden was still projecting propeller-driven fighter aircraft in 1945 equivalent to fighters projected by other nations 1-3 years prior. Since it was obvious by 1945 that jet aircraft was the future the Swedish Air Force decided to immediately scrap all propeller-driven fighter projects and instead make the jump to a jet fighter. Sweden's leading aeronautical firm SAAB, who was already actively working with the Swedish Air Force on the previously mentioned propeller fighters, was tasked with projecting this new jet fighter. Several designs were looked at but by mid-1945 it was decided that a mid-high wing aircraft with a central air intake would be the best option. Due to the mid-high wing it was not possible to house the landing gear in the wings. Instead, it was decided to house the landing gear in the fuselage of the aircraft. This concept got the project name R1001, R standing for "reaktionsmotor" (reaction engine), the Swedish military term for jet engines.

The original specifications for the R1001 called for a radar rangefinder, four Bofors 20 mm akan m/45 cannons mounted in the nose with 180 rounds per gun, external fuel tanks and a top speed of 1,000 km/h. The engine was originally supposed to be an indigenous design by the company STAL but by late 1945 Sweden had gotten the green light for acquiring the new state-of-the-art de Havilland Ghost engine. There are several reasons why Sweden was allowed to buy this engine even before it was finished, but the two main factors were the economic state of Britain after the war and Sweden's good relations with the company de Havilland. The engine was however not the only thing which changed at an early stage. Originally the R1001 featured straight wings, as was common at the time. However, by pure luck Sweden was able to acquire some German WWII research papers from a Swiss source regarding swept wings on aircraft and their increased performance at high speeds. Thus it was decided to change the R1001 design to feature swept wings. The first blueprints of the R1001 featuring swept wings were finished by late 1945 and within 3 years a prototype had been constructed and was ready for flight testing. During these 3 years the design would change even further from the original concept. The radar rangefinder was dropped for unknown reasons, and the Bofors cannons were switched for Hispano designs due to delays at Bofors. By 1947 the aircraft had also received the designation J29.

=== Testing and production ===
The J29 prototype flew for the first time on the 1st of September 1948 and immediately showed incredible performance. The pilot chosen for this flight was SAAB's test pilot at the time, an Englishmen by the name Robert A. "Bob" Moore. He was a British squadron leader with previous experience flying jets and was thus suitable for the tests. The test flight lasted for half an hour and after a successful landing, Moore stated that "on the ground, it's an ugly duckling, but in the air it's a swift." Like many aircraft which pick up a nickname due to a specific feature or shape, the J29 would fairly quickly receive the nickname "Flygande Tunnan" (The Flying Barrel) or just "Tunnan" (The Barrel) for short. Initially thought of as degrading, the nickname Tunnan would not only become the official name for the aircraft but would also start the SAAB tradition of naming their combat aircraft, a tradition which persists to this day.

After correcting a few production errors the prototype would not only achieve the specified top speed of 1,000 km/h but it would even surpass it, achieving a sustainable speed of 1,060 km/h at one point. The design of the J29 showed a lot of promise for the future and talk of future variants would begin even before production had started. In fact, just a month after the prototype had taken to the air, there was talk of implementing attack-rockets and deflatable internal fuel tanks.

Production of the first J29 variant, the J29A, would commence in 1950 and deliveries to the air force would start in early 1951. It was quickly realized that the internal fuel capacity of the J29A was too limited and work began on implementing the previously discussed internal deflatable fuel tanks. This would be realized in a new version of the J29, designated [[J/A29B|J29B]], which entered production and service in 1953. The J29B's new internal fuel tanks gave it a 50% increase in fuel capacity compared to the J29A. The J29B would be followed by an unarmed reconnaissance version called the S29C which had been planned at an early stage. The S29C was to be followed by the [[J29D]], featuring increased armament and an afterburner, but due to a variety of reasons the J29D never entered production. Instead, a modified version of the J29B, called the J29E, would enter service. The E-variant featured a new dog toothed wing which increased maneuverability at high speeds. The J29E was soon followed by the [[J29F]] which was an upgrade-program for 210 J29B and E aircraft, increasing their performance and allowing them to serve throughout the 1960s.

All in all, 661 J29s would be produced for the Swedish Air Force, the largest production run by SAAB ever. The last of these would serve until the late 1970s.

=== Legacy ===
The J29 was a truly historical wonder for its time. After being stranded for the duration of the war, Sweden managed to not only catch up with modern aircraft development in a short amount of time but it was also able to lead jet fighter development in Europe for the time and arguably even into modern times. The J29 was the first swept-wing jet fighter to be mass-produced in Europe and together with the Soviet [[MiG-15]] and American [[F-86A-5|F-86]] it set the bar for how the next generation of fighter aircraft should be. It was extremely fast for its time and actually managed to take home two closed-circuit world speed records during the mid 1950s.

Besides its international legacy, the J29 was the first Swedish-designed aircraft to see combat. In September 1961, as part of the Congo-crisis, five J29Bs were stationed in the Republic of Congo to contribute to a UN peacekeeping mission (ONUC) in the region. This led to the formation of the air wing F 22 which exclusively served in Congo. F 22 was later reinforced by four more J29Bs and two S29C reconnaissance planes in 1962. F 22 would quickly take air superiority in the area which in turn lead to them primarily performing attack-missions during the conflict. No aircraft were lost during the ONUC despite large amounts of ground fire. When the ONUC was terminated in 1964, the aircraft-type had been decommissioned in Sweden and thus it was decided to only send home a select few J29s to Sweden. The majority of the F 22 J29s were blown up on the spot in Congo when the Swedish left the area.

=== J29A ===
Between 1950 and 1953 SAAB would produce 224 J29As. These were delivered to the Swedish Air Force between the 10th of May 1951 and the 22nd of April 1953 and would come to serve in the Swedish Air Force until the early 1960s.

As mentioned previously it lacked the internal deflatable fuel tanks that were fitted to the later models and thus had a fairly limited range. It could however equip two underwing drop tanks weighing up to 600 kg each. This increased the range to acceptable levels. Interestingly, the drop tanks could also be armed as incendiary bombs via a switch box in the cockpit. Beyond drop tanks, the aircraft were also capable of carrying a wide variety of rockets for different missions.

The J29A came to serve in the Swedish Air Force until late 1962 when they were taken out of service. Decommissioned J29As were either scrapped or used as shooting targets. One J29A survives to this day and is owned by the Swedish Air Force museum.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

The survivability of the {{PAGENAME}} is entirely designed for low caliber fire. The chassis is surrounded by plates varying between 5-25mm of thickness, with the front angled to somewhat protect against machine-gun bullets. The {{PAGENAME}} is otherwise entirely exposed to all forms of weaponry, and is expected to be placed behind cover because of this. The launcher is external, and fired by a very exposed launcher and gunner. This means the {{PAGENAME}} has to put distance between itself and the opponent in order to not get knocked out immediately. Ideally, the chassis should be positioned behind cover, only exposing the launcher itself, making it more difficult for enemies to locate the vehicle.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=193|rbMinHp=120}}The {{PAGENAME}} features a 136hp engine giving the vehicle a speed of 38 kph. This is a general downgrade in comparison to the [[UDES 33]], as the lesser horsepower makes it slower and less torque capable. The engine is also petrol, giving it a very high RPM compared to other vehicles. This makes it pretty loud, and distinct in sound compared to tanks around it. The {{PAGENAME}} isn't very good in reverse either, as the transmission only has one reverse gear. The neutral steering is good however, as the missile launcher can't fully traverse. This gives it a very comfortable handling when standing still, something the {{PAGENAME}} is meant for.

{{Specs-Tank-Weapon|1}}

{{main|Rbs 55}}

The Rbs 55 is the same ATGM launcher found on the [[UDES 33]] but gets access to better munitions. The reload time is the same as the UDES so enemies will be able to replace their crew member quicker than your reload. It also gets less ammo, carrying only 8 rounds instead of 10. It is recommended to take a full ammo load as you will definitely run low during an extended battle. The firing angles are more restricted vertically, with only -13° compared to the UDES' -20°. It is horizontally restricted to the 4 o'clock right and 8 o'clock left positions.

However, there is one big upgrade this launcher gets compared to the UDES; the ammunition. It starts off with the potent RB 55B (I-TOW) but can upgrade to the deadly RB 55C (TOW-2). The RB 55B is a good stock munition, being able to penetrate most, if not all, vehicles it faces within its BR range. However, the RB 55C is one of the best ATGMs at its BR range. With 800 mm of penetration, it has the ability to penetrate all vehicles at its BR and more. The slightly higher velocity makes it easier to hit long range targets before they can potentially drive into cover. It's also a Tier II modification so it can be unlocked relatively fast. This makes the launcher one of the most dangerous weapons to face at any range, provided the operator can stay alive, as the gunner is exposed from the waist up on the vehicle.

== Usage in battles ==

* Quickly secure a hull-down position
* Engage targets to prevent them from returning fire
* Switch positions when optional
* Deploy smoke grenades when retreating

The {{PAGENAME}} is very situational, as the vehicle requires a secure sightline, preferably with a lot of distance. The {{PAGENAME}} can be used in closed engagement, when positioned behind teammates. But this is usually at the hope that your team will tank incoming shells for you. Since the reload is slow, and the launcher unable to fire on the move, the {{PAGENAME}} struggles to safely engage opponents safely without any cover. When used behind terrain, the vehicle can safely pull back after launching, and can be difficult to hit due to the small profile of the launcher.

Ideally the {{PAGENAME}} should be played passively. By making use of the profile, the tank should try to stay hull-down while still maintaining a large sightline. Since the vehicle sports deadly ATGM missiles, the {{PAGENAME}} rarely struggles to penetrate from the front. This allows for more creativity, as the vehicle doesn't necessarily need to rely on flanks to deal damage. The vehicle also comes with smoke grenades stock. Although a single salvo, their spread and deploy speed are great, allowing the vehicle to safely retreat without giving the opponent time to react.

{{Notice|Since the missile is easily guided, the Pvrbv 551 works well against helicopers! The missile has to hit the target directly however, as it only detonates on impact.}}

=== Pros and cons ===


'''Pros:'''

* RB 55B (I-TOW) is a potent stock ATGM, penetrating 630 mm of armour
* Comes with a stock 66 mm smoke grenade launcher
* The upgraded RB 55C (TOW-2) is a Tier II upgrade in modifications
* RB 55C penetrates 800 mm of armour and a faster velocity of 329 m/s
* Researchable Night Vision Device

'''Cons:'''

* Has virtually no armour, any heavy calibre machine gun can penetrate it from the front or side
* Gunner is exposed to artillery, aircraft strafing and machine gun fire
* Mediocre mobility, slower than most MBTs
* Less gun depression than its predecessor, [[UDES 33]] (-13° instead of -20°)
* Inherits the same Horizontal Guidance problem with its predecessor (only able to rotate the launcher to a certain angle)
* Vulnerable while firing the launcher

== History ==


In 1983, the Swedish military gave a contract to Hägglunds and Söner to convert Ikv 102 and Ikv 103 vehicles into Pvrbv 551 anti-tank missile carriers. The Ikv 102 and Ikv 103, infantry support vehicles mounting a 105 mm gun, had become obsolete in the past few years. At the same time, the same companies were contracted to convert Ikv 102 and Ikv 103 vehicles into Lvrbv 701 surface-to-air missile carriers. The hull of the Ikv 102/Ikv 103 was plated over, in order to extend the crew compartment the full length of the vehicle. The engine was replaced by a Ford V-6 engine. The armament consisted of a TOW ATGM launcher in the center of the hull, which was raised up through a circular opening in the roof of the vehicle - covered by a two piece hatch - in order to fire the weapon. 55 Pvrbv 551 vehicles were delivered to the Swedish military.

=== [[wt:en/news/6633-development-swedish-ground-vehicles-pvrbv-551-en|Devblog]] ===
During the 1970's, the Swedish military came to realize that their anti-tank and anti-air regiments within the armored branch were substantially lacking in mobility and protection. As a result, studies were initiated in an effort to find potential solutions to this problem.

During the conducted studies, it was found that the previously decommissioned Ikv 102 and 103 SPG's could relatively easily be converted into mobile ATGM and SAM platforms. This sparked the development of several projects in the late 1970's, all of which aimed to convert the old chassis into modern missile carriers.

By the early 1980's, the viability of this undertaking had already successfully been proven through the creation of several prototypes. However, the decision was then made to not simply convert the old chassis, but to substantially rebuild them in order to facilitate necessary improvements.

By the mid 1980's, the work was considered complete and two new vehicles were developed as a result - the Pvrbv 551 and Lvrbv 701 - the former being the ATGM carrier, whereas the latter represented the SAM variant. Both vehicles subsequently entered service with the Swedish military in the mid to late 1980's.

In total, 57 Ikv 103s were converted into the Pvrbv 551 missile carriers, which served with the Swedish military from 1984 until 2000, when the last of the operational units was retired from service.

}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish light tank {{Battle-rating}}. It was introduced in [[Update "Ixwa Strike"]].

== General info ==
[[File:Ikv 91-105 Profile Image.png|left|thumb|370x370px|{{PAGENAME}} as seen from the side.]]
The {{PAGENAME}} is a Swedish light tank that offers accurate firepower with good mobility. The gun fires highly devastating APFSDS rounds that can effectively deal with targets opposing it around flanking routes and open fields. The tank relies heavily on shooting first, as the vehicle features little protection to save it. This requires the user to creatively position the vehicle so enemies are ensured to be shot first, to avoid any possible incoming damage. The gun is well equipped with a two-plane stabilizer and laser rangefinder, which guarantees a perfect shot at any range when used properly. As a secondary line of defence, the {{PAGENAME}} features a good amount of smoke grenades that quickly deploy high above the tank, allowing it to very effectively escape either by reversing or swiftly turning around.

Overall, the {{PAGENAME}} is a great tank for anyone already used to the [[Ikv 91]] looking for a modernized alternative, as well as for anyone interested in a conventional light tank at this high rank.

=== Survivability and armour ===
{{Specs-Tank-Armour}}

The {{PAGENAME}} is a light vehicle. In order to remain agile, and amphibious, the {{PAGENAME}} is forced to sacrifice most of its protection. The hull and turret sport a different shape compared to the earlier [[Ikv 91]], but overall maintain the same level of protection. The upper and lower plates can occasionally protect against .50 cal MG fire, but the turret is often left exposed. The {{PAGENAME}} should always avoid incoming fire from large-calibre machine guns and cannons, as they are more than likely guaranteed to damage the tank internally.

'''Armour type:'''

* Rolled homogeneous armour (hull, turret)
* High-hardness rolled homogeneous armour (hull sides, lower front plate)

[[File:Ikv 91-105 Mobility Image.png|thumb|{{PAGENAME}} moving through tall grass]]

{{tankMobility|abMinHp=558|rbMinHp=318}}

Although the mobility of the {{PAGENAME}} can come off as mediocre, the overall agility of the vehicle is very comfortable in battle. The tank is able to neutral steer without any issue, and has enough speed in both directions to avoid most situations. The engine is essentially identical to the prior [[Ikv 91]], and thus struggles a lot when difficult slopes are encountered, considering the tank is significantly heavier than its original variant. Despite this the tank is still fully amphibious, and with the now added stabilizer, is very potent when submerged.

[[File:Ikv 91-105 Firing Image.png|thumb|{{PAGENAME}} firing the main 105 mm cannon.]]
The 105 mm cannon found on the {{PAGENAME}} is a two-plane stabilized gun, capable of firing sub-calibre munitions, such as the Slpprj m/80, that perform favourably against most vehicles it faces. Although the penetration might seem like a downgrade compared to the HEATFS found on the prior [[Ikv 91]], the shells fired have a much higher velocity, and devastating penetration values at high angles.

The cannon is paired with a laser rangefinder, which automatically adjusts the elevation at range. This makes the {{PAGENAME}} very capable at distanced engagements, as the gun can fire with perfect accuracy as soon as the target has been measured. The user still has to account for target movement, as well as objects or terrain obstructing the target. But when used carefully, the gun only really requires a single shot per target.

{{main|ksp m/39B (8 mm)}}

The {{PAGENAME}} features two 8 mm machine guns. These are quite common for most Swedish tankers, and are only effective against exposed crew, and slow flying helicopters. The 8 mm rounds are quite effective at dealing with light obstacles like small fences and foliage, but should always be used with caution, as the tracers can expose the location of the vehicle.

== Usage in battles ==


When playing the {{PAGENAME}}, it's important to play like a light tank. The {{PAGENAME}}, although nimble, can be quite slow when stock. Overall the tank struggles to maintain a high speed, and will often lag behind other vehicles of the same class. The great compensation for this is the firepower. Thanks to a deadly arsenal of shells, along with a stabilizer, the tank engages any vehicle it faces with ease. Paired with a stabilizer and laser rangefinder, the {{PAGENAME}} can comfortably attack at any distance. This makes the {{PAGENAME}} very flexible, as you can use it both as a long range reconnaissance sniper, and a close range glass cannon.

When a match starts, it's always optimal to look for a favourable location within reach. If mobility allows you to surprise your opponents, it can be a favourable choice, especially in close quarter maps. While other situations could call for distanced engagements, such as unexpected sight-lines and well hidden ambushes, as the tank is fairly easy to hide. On top of its small profile, the {{PAGENAME}} features a good amount of smoke launchers, that quickly deploy and conceal the vehicle when necessary.

A typical engagement scenario:

# Rush to a position with a favourable line of sight
# Engage opponents without exposing yourself
# Scout targets for your team
# Deploy smoke grenades to help your team retreat

=== Pros and cons ===


'''Pros:'''

* Hard-hitting 105 mm cannon
* Amphibious design
* Small profile, shorter than most tanks
* Great mobility and traverse
* Ability to scout and repair
* Access to night vision devices

'''Cons:'''

* Lightly armoured, insufficient even to resist .50 cal MG fire
* Mediocre rate of fire
* Inconsistent depression angles, uncomfortable to aim behind cover
* Vulnerable to aircraft

== History ==

AB Hägglunds & Söner, the company behind the Ikv 91 light tank, had high hopes for a successful export market, outside the domestic use of the platform. The design had been ill-fated early since the chassis was too weak to handle high-pressure weaponry, necessary for sub-caliber munitions. By the 80s however, the ability to mount a high pressure 105mm cannon was taken to consideration, as Bofors had developed a low-recoil variant. This design idea quickly took shape in 1983 as India was looking for a new amphibious light tank. The requirements involved full firing capability when submerged, meaning the cannon had to be stabilized. The vehicle introduced a commanders fire control system, as well as Infra-red night vision devices provided by SAAB. India evaluated the design, along with other countries, but ultimately no series production was ever established. The Swedish Army considered a possible modernization of the Ikv 91 by using this 105mm gun, but found the design too weak for such high weaponry.

The Fokker D.XXI is a fairly pleasurable aircraft to play. Its manoeuvrability is quite good, being able to outturn a lot of aircraft of this BR. Also, its climb rate is great for its BR. However, keep in mind that it it rather slow, and might not be able to keep up with other fighters.

{{main|Oerlikon FF (20 mm)|FN-Browning M.36 No.3 (7.7 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 2 x 20 mm Oerlikon FF cannons, wing-mounted (60 rpg = 120 total)
* 2 x 7.7 mm FN-Browning M.36 No.3 machine guns, nose-mounted (500 rpg = 1,000 total)

== Usage in battles ==

* Climb at ~15° with minimum fuel
* Maintain altitude over opponents
* Dogfight heavier opponents at height
* Dive down on slower targets below

The {{PAGENAME}} is highly agile for its class. This allows it to comfortably defend itself against most opponents, that will often struggle to get a good shot. The downside to this is speed. The {{PAGENAME}} is quite primitive, with a lot of drag coming from both the landing gear and wing-mounted cannons. This makes the {{PAGENAME}} unable to run away from most opponents, as even some biplanes are capable of catching up. This doesn't mean the plane weak however, as the engine provides well over 700 horsepower to this light machine, allowing it to climb high above most targets.

The strategy when using the {{PAGENAME}} should be to make the plane as light as possible, while using the engine to gain a height advantage. This can be achieved by taking the minimum amount of fuel, and putting the plane to a ~15° climb at take-off. This ensures that the plane will be the lightest aircraft at altitude, making any dogfight at height favorable, as most planes capable of reaching this height are much more cumbersome in comparison. Once the opponents up high have been cleared, the {{PAGENAME}} is able to make use of the altitude to boom & zoom opponents below with ease, as the plane can safely dive without damaging itself.

{{Notice|Pilots more comfortable with dogfighting can utilize the '''Landing flaps''' when stalling, to quickly flip back over. This allows for some advanced tactics against slower opponents.}}

=== Pros and cons ===

'''Pros:'''

* Powerful armament consisting of 2 x 20 mms and 2 x 7.7 mms, can easily start fires and shred biplanes
* Above average climb rate for its BR
* Only one fuel tank, so fires usually would not be started if the aircraft was tailed
* Great turn time (16 seconds in RB)
* Engine takes a while to overheat on WEP
* Does not rip or even compress at little over 600 km/h, allowing it to safely dive on its opponents
* Short takeoff run
* As a premium aircraft, has better SL and RP rewards than regular aircraft
* Fixed landing gear makes landings easier and more simplified

'''Cons:'''

* Rather slow for its BR
* Only has landing flaps
* 20 mm cannons technically only have 60 rounds (60 rounds per gun, but they fire at the same time)
* Cannons have a rather slow rate of fire
* Cannons easily overheat after a short time of continuous firing
* No armour

== History ==

=== [[wt:en/news/7045-development-fokker-d-xxi-the-flying-dutchman-en|Devblog]] ===
Development of what would become the Fokker D.XXI began in late 1934 with engineers at the Fokker company seeking to design a modern fighter aircraft, incorporating some of the latest aviation technologies. In 1935, the Dutch Air Force ordered the construction of a prototype which would be evaluated by its East Indies branch, as a result of the aircraft being seen as suitable for defending Dutch overseas assets.

Although its maiden flight in 1936 showed enough promise, the fate of the Fokker D.XXI was "hanging in the air" for a time due to a change in doctrine within the Dutch Air Force. As a result, Fokker began looking into promoting the aircraft on the export market, hoping to find foreign customers.

Fortunately, Fokker received interest from both Denmark and Finland to purchase a number of aircraft as well as rights to production. At the same time, domestic interest was also revived, resulting in the start of production in 1937.

Despite being a Dutch design, the Fokker D.XXI was predominantly produced and employed by Finland. Having built and operated around ⅔ of all D.XXIs, the Finnish Fokkers distinguished themselves during the Winter and Continuation War, although with less success in the latter due to their dated design. The Dutch Fokkers also put up a stiff resistance to the invading German forces in May 1940, shooting down a number of enemy aircraft, including several superior Messerschmitt Bf 109s. In the end, approximately 150 D.XXIs were built, serving up until 1949 with Finnish forces.

{{Specs-Card
|code=sw_lvrbv_701
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish SPAA {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

== General info ==
First to introduce the SAM gameplay to Sweden, the {{PAGENAME}} is a lightly armoured chassis identical to the [[Pvrbv 551]], both being based on the much older [[Ikv 103]]. The design is simply a man-portable RBS 70 missile system placed inside the refurbished chassis. Due to this structure, the {{PAGENAME}} features no radar to scan for incoming targets, and relies on a single missile salvo with a long interval between reloads. This, combined with bad traversal of the launcher, and low mobility, means that the {{PAGENAME}} is forced to engage carefully, as it has no proper way of defending itself outside of getting the first jump.

Though to list its strengths, the {{PAGENAME}} features a high agile and reliable missile system. The RB 70 is incredibly devastating to those that face it, as the SAM can easily damage unsuspecting enemy aircraft, since there is no radar to notify them of your presence. And thanks to the agility, the missile works comfortably at both closer and longer ranges.

=== Survivability and armour ===
{{Specs-Tank-Armour}}


Frontal armour on the {{PAGENAME}} consists of 20 to 25 mm of rolled homogeneous armour. Ideally, this can provide 28 to 30 mm of effective protection which should stop most low calibre machine gun fire, as well as .50 cal machine guns.

Side armour on the {{PAGENAME}} consists of 10 mm rolled homogeneous armour which, due to its limited angles, only affords protection against low calibre machine guns.

The turret has no armour whatsoever.

The crew of 4 consists of a driver, gunner, loader and commander all positioned closely together in the front half of the vehicle.

Overall, protection on the {{PAGENAME}} isn't spectacular and with a compact crew placement, including an exposed gunner, a simple burst of machine-gun fire from a .50 cal or larger fired at the sides or top can leave you knocked out. Its low profile and compact size does, however, work in your favour and lets you hide from most other ground vehicles and any aircraft/helicopters that haven't spotted you launching a missile.

'''General'''

The {{PAGENAME}} is difficult to get used to, as the high BR ensures a punishing top-tier environment. Since the {{PAGENAME}} is meant for anti-air operation, the targets above you are usually easy pickings. The main threat for the {{PAGENAME}} is instead ground vehicles, as the tank has almost no way to defend itself against such opponents. The ideal way to play the vehicle is to stick close to your allied tanks, as they can deal with the ground threats for you, while you keep the airspace safe. The {{PAGENAME}} feature scouting, and can easily aid teammates that need information about enemy positions, or need to be repaired.

'''Engaging air targets'''

When the {{PAGENAME}} spots an air target, it's important to think about what you're engaging. Helicopters such as the [[Ka-50]], can easily see the missile coming, and are usually expecting some sort of retaliation for launching missiles away from the battlefield. A tip is to not attempt to lock such targets, and instead estimate the distance, and launch it when they're busy. When fighting helicopters at close range, such as the [[AH-1G]], or [[Mi-28N]], it is important to launch as soon as possible, and destroy them before they get above you, as you have no ability to destroy them at point-blank distance.

Aircraft are slightly more difficult to destroy, as the RB 70 missile lacks significant velocity compared to other systems. Instead, the manoeuvrability of the missile comes to a lot of help as planes will struggle to avoid it while manoeuvring. When first engaging an aircraft, knowing if it has RWR is critical, as aircraft aware of you might go for another pass or even worse strafe you from a blind spot. The missile works best when attacking at medium range, where the aircraft is either approaching or flying parallel to your position. Aircraft are usually easy to kill, but should always be engaged with consideration, as your reload leaves you vulnerable to counter-attacks from the same opponent.

{{Notice|The {{PAGENAME}} can be used to engage light vehicles, as the later missile has a lot of penetration. But engaging has to be done with caution due to the slow reload!}}

=== Pros and cons ===


'''Pros:'''

* RB 70 Mk.2 missiles have 200 mm of penetration which can be useful against light ground targets
* Small vehicle profile allows you to hide behind cover effectively
* Unarmoured turret can help in reducing the visibility of the vehicle behind cover
* Smoke grenades can help when getting strafed by aircraft
* Upgraded RB 70 Mk.2 missiles are only a Tier II modification
* Can use the scouting mechanic to tag enemies and also help repair teammates

'''Cons:'''

* No secondary armament
* No search radar, only a tracking radar meaning you have to manually find targets
* Relatively sluggish turret rotation speed makes acquiring fast low flying targets difficult
* Only 200° total (±100°) of missile launcher rotation
* Max elevation of 35° makes tracking high altitude targets pretty much impossible
* Average mobility with very slow reverse speed
* Unarmoured turret leaves the gunner very vulnerable to knockouts

== History ==


In 1983, the Swedish military gave a contract to Hägglunds and Söner to convert Ikv 102 and Ikv 103 vehicles into Lvrbv 701 surface-to-air missile carriers. The Ikv 102 and Ikv 103, infantry support vehicles mounting a 105 mm gun, had become obsolete in the past few years. At the same time, the same companies were contracted to convert Ikv 102 and Ikv 103 vehicles into Pvrbv 551 anti-tank missile carriers. The hull of the Ikv 102/Ikv 103 was plated over, in order to extend the crew compartment the full length of the vehicle. The engine was replaced by a Ford V-6 engine. The armament consisted of a RBS 70 surface-to-air missile launcher in the center of the hull, which was raised up through a circular opening in the roof of the vehicle - covered by a two piece hatch - in order to fire the weapon.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].

The {{PAGENAME}} is a jet-powered version of the prior [[A21A-3]], giving it higher speeds and heavier ordnance.

== General info ==
[[File:A21RB Formation.png|left|thumb|478x478px|Two {{PAGENAME}} flying in formation]]
The {{PAGENAME}} is a highly maneuverable plane, with a good climb rate. The guns, although a downgrade from the previous propeller-driven 13 mm version, they still provide enough firepower to down most targets efficiently. The {{PAGENAME}} is also the first to feature the iconic "Paddan" gunpod, giving it additional lead downrange. Along with central-mounted rockets, the plane is comfortable in both Air Realistic and Ground Realistic battles. The only downside is the airframe, that prevents the aircraft from reaching higher speeds. This is due to the engine being a bit too powerful for the plane, making it common to rip in straight lines and shallow dives.

The plane is an overall great introduction for anyone looking to learn jet-aircraft, as the vehicle handles very similar to its propeller-driven counterpart, while at a much higher speed than before.

=== Flight performance ===

{{Specs-Avia-Flight}}

The {{PAGENAME}} is distinctly different in looks and performance from all other planes found at the same BR-range. Along with the Yak-15, the Saab 21R is one of the two propeller-driven planes successfully converted into jet propulsion. Just like its Soviet counterpart, the solution comes at the cost of speed. Although a lot more powerful than the A21A-3, it still has the same airframe limitations, resulting in good turn-rate. The climb-rate is also significantly improved due to the weight of the vehicle, resulting in good vertical energy with the ability to stall out slower opponents. Getting back down can prove difficult however, as the {{PAGENAME}} has a rip speed of just 850 km/h, which it can accidentally reach if not careful. To avoid this, the plane features a small set of air-brakes, which aids in maintaining a safe speed. Experienced pilots can find a good use for them, along with the powerful flaps, to force overshoots, or to out-turn propeller-driven opponents. Be careful with the engine however! The propulsion of the {{PAGENAME}} is very primitive, and suffers from fuel starvation during extreme maneuvers, especially in negative G-loads. This can be fatal when fighting vertically, as the engine drops all power almost immediately, and has to spool back up again before reaching the same efficiency as before.

=== Survivability and armour ===

{{Specs-Avia-Armour}}
[[File:J21 Armour Plating.png|450px|thumb|right|Protective components found in the '''{{PAGENAME}}'''.]]

* 10 mm steel - Firewall armour plate
* 10 mm steel - Firewall cover armour plate
* 10 mm steel - Pilot's back armour plate
* 60 mm bulletproof glass

Although the {{PAGENAME}} is meant for ground-attack, the plane lacks significant protection to withstand a lot of incoming fire. The pilot is well protected by metal plates and bulletproof glass, but the pilot's safety isn't the primary concern for the {{PAGENAME}}, as the tail section is incredibly vulnerable. This is due to the twin-boom design, making a tailstrike twice as likely. And since the tail connects to the wing-section, the plane tends to lose tail-control when struck by wing damage. The engine is very large in comparison to the rest of the plane, making it a common target. The {{PAGENAME}} should avoid all possible damage, as surviving large amounts of fire is highly unlikely. Pulling away from head-on engagements increases the survivability immensely. Avoiding the enemy airfield is also important, as the {{PAGENAME}} lacks the speed to keep it safe from flak fire.

=== Modifications and economy ===
{{Specs-Economy}}

== Armaments ==
{{Specs-Avia-Armaments}}
=== Offensive armament ===

{{Specs-Avia-Offensive}}

{{main|Akan m/45 (20 mm)|Akan m/39A (12.7 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 1 x 20 mm Akan m/45 cannon, nose-mounted (140 rpg)
* 2 x 12.7 mm Akan m/39A machine guns, nose-mounted (350 rpg = 700 total)
* 2 x 12.7 mm Akan m/39A machine guns, wing-mounted (325 rpg = 650 total)

The {{PAGENAME}} shares the same 20 mm cannon found on the previous A21A-3. This cannon is near identical to the [[Hispano Mk.V (20 mm)|Hispano Mk.V]], only with a 30 rpm lower fire-rate. The shells perform the same as on all the other 20 mm jets, making it highly devastating against all types of aircraft. Armoured targets perform favourably with this cannon, as the air-target belt can cause some mishaps during short bursts. The cannon runs out of ammunition quite quickly compared to the machine-guns, so saving it by only making use of the small calibre guns first can be ideal for spraying.

The {{PAGENAME}} features .50 cal machine guns, being identical to the later American ones. Although a direct downgrade from the Swedish 13 mm previously found on the plane, the {{PAGENAME}} makes good use of these cannons, as they allow for distanced engagements, along with additional firepower to back up the 20 mm cannon. Their ammo count is quite high as well, making them great for strafing, and finishing off heavy bombers.

=== Suspended armament ===

{{Specs-Avia-Suspended}}

{{main|hprak m/49|psrak m/49A|srak m/51|Ksp m/22 (8 mm)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 8 x 8 mm Ksp m/22 machine guns, belly-mounted (gunpod) (100 rpg = 800 total)
* 10 x m/49A rockets
* 10 x srak m/51 rockets
* 5 x hprak m/49 rockets

[[File:A21RB Armaments.png|thumb|313x313px|{{PAGENAME}} carrying m/49A rockets]]
A unique feature only found on the {{PAGENAME}} is the ability to use the abstract gunpod. Commonly known as "Paddan" (directly translated to "The toad"), the gunpod features eight 8 mm Ksp m/22, repurposed from old J8 Gladiators. Although weak guns by nature, having eight of them gives the {{PAGENAME}} unprecedented fire-power shredding anything that goes head-to-head with it. The ammunition count is low, however, which forces pilots to use them carefully. Saving the gunpod by only using .50 cal on distant opponents, allows the {{PAGENAME}} to get rid of opponents during short bursts, which can be incredibly useful if mastered correctly. It's still important to mention that this gunpod is incredibly heavy and not very aerodynamic, and thus takes a heavy hit on the overall speed of the plane.

The {{PAGENAME}} has a lot of additional advantages over the prior A21A-3, especially when it comes to the ground ordnance. The ground rockets are finally mounted in the middle of the plane, firing one at a time starting from the right. Since the Swedish rockets, especially the m/49 rockets, feature amazing ballistics with little inaccuracy, that along with high penetration, makes for some highly effective air-support. And since the {{PAGENAME}} is quite light, it can easily perform several passes on opponents, which is quite important against heavy opponents.

== Usage in battles ==

'''Air Realistic Battles'''

* Climb to altitude
* Energy-fight opponents by lowering their speed
* Boom & Zoom people below you
* Dogfight slow targets when necessary
* Fire machine guns and cannons separately to save ammo

Despite being jet-powered, the {{PAGENAME}} still performs best when played like a propeller driven aircraft. The airplane struggles to reach high speeds, and drops it fairly quickly when maneuvering. So the best use of the new engine is to gain altitude. Although weak in performance compared to earlier jets, the {{PAGENAME}} is decent at climbing to altitude, and can very efficiently deal with targets thanks to the high agility offered at lower speeds. Although the flaps are designed for much lower speeds (similar to the A21A-3), the plane still performs similar to the propeller variant when turning, making them less desired than on other jets.

The best way to start a match is to immediately gain altitude. A height advantage around 5km is usually ideal to avoid losing vital speed when fighting, as the plane can simply dive to gain more velocity. The best way to handle opponents, is to single them out from their team, and forcing them to dogfight, as the {{PAGENAME}} is too slow to chase anyone down. The {{PAGENAME}} is also efficient against propeller aircraft, as it can comfortably turn-fight, while keeping a higher speed. When paired with the devastating firepower it provides, the {{PAGENAME}} becomes deadly when used properly.

'''Ground Realistic Battles'''

* Use minimum fuel and m/49A rockets
* Stay low or high above the ground to avoid SPAA
* Prioritize air-targets
* Attack opponents directly from the side or slightly from above (rockets)
* Strafe directly from above (8mm gunpod)

The {{PAGENAME}} is even more effective in combined battles, as the platform is highly agile, ideal for close and precise rocket attacks. To compliment this, the {{PAGENAME}} features a fantastic rocket placement, in the center of the aircraft. These launch one at a time, similar to other Swedish aircraft. This gives the {{PAGENAME}} 10 single rocket salvos (m/49A), that can effectively kill one tank each when aimed properly. It's ideal to launch each rocket with the crosshair pointed slightly above the target, as they are placed fairly low. A creative pilot could also make use of the much larger m/49 rockets, but these require a lot of compensation in elevation, and are overall much more difficult to make use of.

While playing the {{PAGENAME}} in Ground RB, it's important to still prioritize air targets. The {{PAGENAME}} is still agile, despite carrying suspended armaments, and is even cheaper to spawn with the 8mm gunpod, which shreds both aircraft and lightly armoured vehicles. Prioritizing aircraft will substantially help both you, and the team below, as they are capable of dealing equally as much damage.

=== Pros and cons ===


'''Pros:'''

* Highly maneuverable - Competes with propeller driven aircraft
* Accurate and powerful rockets - Highly effective against most vehicles
* Upgraded engine compared to the [[J21RA]] - Better rate of climb and acceleration
* Familiar layout for seasoned Swede Pilots - Same gun placement as all previous Saab 21's
* Useful air-brakes - Good at avoiding higher speeds
* Access to suspended 8 x 8 mm gunpod
* Access to modern 12.77 rounds - Incredibly efficient

'''Cons:'''

* Low top speed - Can't reach 800 km/h without tearing off its wings
* Downgraded armament - 12.7 mm machine guns instead of the old 13 mm
* Small fuel tank with limited fuel choice - Either 20 or 9 minutes of fuel
* Engine prone to fuel starvation - negative G-load turns the engine off
* Cumbersome rocket ramp - reduces top-speed by almost 100 km/h
* External gunpod lacks significant ammunition count

Despite being jet-powered, the {{PAGENAME}} still performs best when played like a propeller driven aircraft. The airplane struggles to reach high speeds, and drops it fairly quickly when maneuvering. So the best use of the new engine is to gain altitude. Although weak in performance compared to earlier jets, the {{PAGENAME}} is decent at climbing to altitude, and can very efficiently deal with targets thanks to the high agility offered at lower speeds. Although the flaps are designed for much lower speeds (similar to the J21A-2), the plane still performs similar to the propeller variant when turning, making them less desired than on other jets.

The best way to start a match is to immediately gain altitude. A height advantage around 5km is usually ideal to avoid losing vital speed when fighting, as the plane can simply dive to gain more velocity. The best way to handle opponents, is to single them out from their team, and forcing them to dogfight, as the {{PAGENAME}} is too slow to chase anyone down. The {{PAGENAME}} is also efficient against propeller aircraft, as it can comfortably turn-fight, while keeping a higher speed. When paired with the devastating firepower it provides, the {{PAGENAME}} becomes deadly when used properly.

The {{PAGENAME}} can be used in combined battles (Ground RB & Ground SB), but is overall less efficient compared to the [[A21RB]], as it lacks suspended armaments.

=== Pros and cons ===


'''Pros:'''

* Highly maneuverable - Competes with propeller driven aircraft
* Familiar layout for seasoned Swede Pilots - Same gun placement as all previous Saab 21's
* Useful air-brakes - Good at avoiding higher speeds
* No wing-tanks compared to the [[A21RB]] - Less likely to be set on fire
* Access to modern 12.7mm rounds - Highly efficient at dealing damage

'''Cons:'''

* Low top speed - Can't reach 800 km/h without tearing off its wings
* Downgraded armament - 12.7 mm machine guns instead of the old 13 mm
* Small fuel tank with limited fuel choice - Either 21 or 6 minutes of fuel
* Engine prone to fuel starvation - negative G-load turns the engine off
* Weaker engine compared to the A21RB

== History ==

The J21RA is a variant of the Saab 21R, a unique early jet fighter developed from the previous Saab 21. The aircraft was one of two semi-successful conversions of propeller fighters into jet fighters, the other being the Soviet Yak-15 (which was converted from the Yak 1/3/7/9 series). The aircraft served as one of the first jet-engined aircraft in Swedish service and was also the first jet-engined-aircraft produced by Saab. The Saab 21Rs were retired in the 1950s with the introduction of more advanced Swedish aircraft.

During WWII, the Saab aircraft production company produced the Saab 21, a fighter aircraft with an unorthodox twin-boom configuration along with a German DB 605B engine. The first such aircraft flew in July of 1943 and entered service soon thereafter. During this time, the Saab firm explored various options for upgrading their Saab 21s, including a variant powered by a Rolls-Royce Griffon engine producing 2000 hp. However, at the same time, the Saab firm was also investigating the possibility of a jet-engined fighter; this led the Saab firm to pursue a jet-engined variant of the Saab 21 for use with the Swedish air force.

In 1947, Saab received the first older J21 airframes for conversion into a jet fighter, designated the J21R; the airframes were extensively modified to house a British-sourced De Havilland Goblin turbojet in place of the DB 605 and its corresponding propeller. Extensive modifications were also made to the aircraft’s fuselage, wings and tailplane; notably, the tail section was redesigned so that the elevator would be clear of the jet engine’s exhaust. Additionally, the aircraft featured an ejection seat, a novelty at the time.

Initially, a production run of 124 aircraft was planned; however, this was cut to 64 aircraft when the more-advanced J29 Tunnan became available in 1948. The J21RA was the designation given to the first 34 of these aircraft, powered by the Goblin 2 engine, while the J21RB was powered by an indigenously-built Goblin 3 engine. The J21 was retired in the mid-1950s with the introduction of more advanced aircraft such as the Saab 32 Lansen; no original aircraft were preserved but an old Saab 21 airframe was converted to resemble the Saab 21R; this aircraft is displayed at the Swedish Air Force Museum.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish light tank {{Battle-rating}}. It was introduced in [[Update "Ixwa Strike"]].

== General info ==
[[File:Ikv 91-105 Profile Image.png|left|thumb|370x370px|{{PAGENAME}} as seen from the side.]]
The {{PAGENAME}} is a Swedish Light tank, that offers accurate firepower with good mobility. The gun fires highly devastating APFSDS rounds, that can effectively deal with targets opposing it around flanking routes and open fields. The tank relies heavily on shooting first, as the vehicles features little protection to save it. This requires the user to creatively position the vehicle so enemies are ensured to be shot first, to avoid any possible incoming damage. The gun is well equipped with a two-plane stabilizer, and laser rangefinder, which guarantees a perfect shot at any range when used properly. As a secondary line of defense, the {{PAGENAME}} features a good amount of smoke grenades, that quickly deploy high above the tank, allowing it to very effectively escape either by reversing or swiftly turning around.

Overall, the {{PAGENAME}} is a great tank for anyone already used to the [[Ikv 91]], looking for a modernized alternative. And for anyone interested in a conventional light tank at this high rank.

=== Survivability and armour ===
{{Specs-Tank-Armour}}

The {{PAGENAME}} is a light vehicle. In order to remain agile, and amphibious, the {{PAGENAME}} is forced to sacrifice most of its protection. The hull and turret sport a different shape compared to the earlier Ikv 91, but overall maintain the same level of protection. The upper and lower plates can occasionally protect against .50 cal MG fire, but the turret is often left exposed. The {{PAGENAME}} should always avoid incoming fire from large-caliber machine guns and cannons, as they are more than likely guaranteed to damage the tank internally.

'''Armour type:'''

* Rolled homogeneous armour (hull, turret)
* High-hardness rolled homogeneous armour (hull sides, lower front plate)

{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=558|rbMinHp=318}}
[[File:Ikv 91-105 Mobility Image.png|thumb|{{PAGENAME}} moving through tall grass]]
Although the mobility of the {{PAGENAME}} can come off as mediocre, the overall agility of the vehicle is very comfortable in battle. The tank is able to neutral steer without any issue, and has enough speed in both directions to avoid most situations. The engine is essentially identical to the prior [[Ikv 91]], and thus struggles a lot when difficult slopes are encountered, considering the tank is significantly heavier than its original variant. Despite this the tank is still fully amphibious, and with the now added stabilizer, is very potent when submerged.

[[File:Ikv 91-105 Firing Image.png|thumb|{{PAGENAME}} firing the main 105mm cannon.]]
The 105mm cannon found inside the {{PAGENAME}} is a two-plane stabilized gun, capable of firing sub-caliber munitions such as the Slpprj m/80, that perform favorably against most vehicles it faces. Although the penetration might seem like a downgrade compared to the HEAT-FS found inside the prior Ikv 91, the shells fired have a much higher velocity, and devastating penetration values at high angles.

The cannon is paired with a laser rangefinder, which automatically adjust the elevation at range. This makes the {{PAGENAME}} very capable at distanced engagements, as the gun can fire with perfect accuracy as soon as the target has been measured. The user still has to account for target movement, as well as objects or terrain obstructing the target. But when used carefully, the gun only really requires a single shot per target.

'''Notes''':

* Shells are modeled individually and disappear after having been shot or loaded.
* Rack 3 is a first stage ammo rack. It totals 11 shells and gets filled first when loading up the tank.
* This rack is also emptied early: the rack depletion order at full capacity is: 3 - 1 - 2.
* Simply not firing when the gun is loaded will move ammo from racks 1-2 into rack 3. Firing will interrupt the restocking of the ready racks.
* One shell is always stored in the breech.

=== Machine guns ===
{{Specs-Tank-Weapon|2}}
{{Specs-Tank-Weapon|3}}

{{main|ksp m/39B (8 mm)}}
The {{PAGENAME}} features two 8mm machine guns. These are quite common for most Swedish tankers, and are only effective against exposed crew, and slow flying helicopters. The 8mm shells are quite effective at dealing with obstructions however, like small fences and foliage. But should always be used with caution, as the tracers can expose the location of the vehicle.

|-
|}

== Usage in battles ==

* Rush to a favourable sightline or position
* Engage opponents without exposing yourself
* Scout targets for your team
* Deploy smoke grenades to help your team retreat

When playing the {{PAGENAME}}, it's important to play like a light tank. The {{PAGENAME}}, although nimble, can be quite slow when stock. Overall the tank struggles to maintain a high speed, and will often lack behind other vehicles of the same class. The great compensation for this is the firepower. Thanks to a deadly arsenal of shells, along with a stabilizer, the tank engages any vehicle it faces with ease. Paired with a stabilizer and laser rangefinder, the {{PAGENAME}} can comfortably attack at any distance. This makes the {{PAGENAME}} very flexible, as you can use it both as a long range reconnaissance sniper, and a close range glass cannon.

When a match starts, it's always optimal to look for a favorable location within reach. If mobility allows you to surprise your opponents, it can be a favorable choice, especially in close quarter maps. While other situations could call for distanced engagements, such as unexpected sight-lines and well hidden ambushes, as the tank is fairly easy to hide. On top of its small profile, the {{PAGENAME}} features a good amount of smoke launchers, that quickly deploy and conceal the vehicle when necessary.

=== Pros and cons ===


'''Pros:'''

* Hard-hitting 105 mm cannon
* Amphibious design
* Small profile, shorter than most tanks
* Great mobility and traverse
* Ability to scout and repair
* Access to night vision devices

'''Cons:'''

* Lightly armoured, insufficient even to resist .50 cal MG fire
* Mediocre rate of fire
* Inconsistent depression angles, uncomfortable to aim behind cover
* Vulnerable to aircraft

Lvrbv 701

2021-06-22T13:48:01Z

U26781411: Added General info, ammo racks, and usage in battles.

{{Specs-Card
|code=sw_lvrbv_701
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish SPAA {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

== General info ==
First to introduce the SAM gameplay to Sweden, the {{PAGENAME}} is a lightly armoured chassis identical to the [[Pvrbv 551]], both being based on the much older [[Ikv 103]]. The design is simply a man-portable RBS 70 missile system placed inside the refurbished chassis. Due to this structure, the {{PAGENAME}} features no radar to scan for incoming targets, and relies on a single missile salvo with a long interval between reloads. This, combined with bad traversal of the launcher, and low mobility, means that the {{PAGENAME}} is forced to engage carefully, as it has no proper way of defending itself outside of getting the first jump.

Though to list its strengths, the {{PAGENAME}} features a high agile and reliable missile system. The RB 70 is incredibly devastating to those that face it, as the SAM can quite unnoticed damage enemy aircraft, since there is no radar to notify them of your presence. And thanks to the agility, the missile works comfortably at both closer and longer ranges.

=== Survivability and armour ===
{{Specs-Tank-Armour}}


Frontal armour on the {{PAGENAME}} consists of 20 to 25 mm of rolled homogeneous armour. Ideally, this can provide 28 to 30 mm of effective protection which should stop most low calibre machine gun fire, as well as .50 cal machine guns.

Side armour on the {{PAGENAME}} consists of 10 mm rolled homogeneous armour which, due to its limited angles, only affords protection against low calibre machine guns.

The turret has no armour whatsoever.

The crew of 4 consists of a driver, gunner, loader and commander all positioned closely together in the front half of the vehicle.

Overall, protection on the {{PAGENAME}} isn't spectacular and with a compact crew placement, including an exposed gunner, a simple burst of machine-gun fire from a .50 cal or larger fired at the sides or top can leave you knocked out. Its low profile and compact size does, however, work in your favour and lets you hide from most other ground vehicles and any aircraft/helicopters that haven't spotted you launching a missile.

* The first rack depletes from left to right
* The launcher always contains one piece of ammunition

== Usage in battles ==

* Stay behind your team, but close to the front line
* Scout ground targets and repair allies
* Keep behind cover and focus on incoming planes
* Use smoke grenades when retreating
* Don't let opponents get above you

'''General'''

The {{PAGENAME}} is difficult to get used to, as the high BR ensures a punishing top-tier environment. Since the {{PAGENAME}} is meant for anti-air operation, the targets above you are usually easy pickings. The main threat for the {{PAGENAME}} is instead ground vehicles, as the tank has almost no way to defend itself against such opponents. The ideal way to play the vehicle is to stick close to your allied tanks, as they can deal with the ground threats for you, while you keep the airspace safe. The {{PAGENAME}} feature scouting, and can easily aid teammates that need information about enemy positions, or need to be repaired.

'''Engaging Air Targets'''

When the {{PAGENAME}} spots an air target, it's important to think about what you're engaging. Helicopters such as the [[Ka-50]], can easily see the missile coming, and are usually expecting some sort of retaliation for launching missiles away from the battlefield. A tip is to not attempt to lock such targets, and instead estimate the distance, and launch it when they're busy. When fighting helicopters at close range, such as the [[AH-1G]], or [[Mi-28N]], it is important to launch as soon as possible, and destroy them before they get above you, as you have no ability to destroy them at point-blank distance.

Aircraft are slightly more difficult to destroy, as the RB 70 missile lacks significant velocity compared to other systems. Instead, the maneuverability of the missile comes to a lot of help as planes will struggle to avoid it while maneuvering. When first engaging an aircraft, knowing if it has RWR is critical, as aircraft aware of you might go for another pass or even worse strafe you from a blind spot. The missile works best when attacking at medium range, where the aircraft is either approaching or flying parallel to your position. Aircraft are usually easy to kill, but should always be engaged with consideration, as your reload leaves you vulnerable to counter-attacks from the same opponent.

{{Notice|The {{PAGENAME}} can be used to engage light vehicles, as the later missile has a lot of penetration. But engaging has to be done with caution due to the slow reload!}}
=== Pros and cons ===


'''Pros:'''

* RB 70 Mk.2 missiles have 200 mm of penetration which can be useful against light ground targets
* Small vehicle profile allows you to hide behind cover effectively
* Unarmoured turret can help in reducing the visibility of the vehicle behind cover
* Smoke grenades can help when getting strafed by aircraft
* Upgraded RB 70 Mk.2 missiles are only a Tier II modification
* Can use the scouting mechanic to tag enemies and also help repair teammates

'''Cons:'''

* No secondary armament
* No search radar, only a tracking radar meaning you have to manually find targets
* Relatively sluggish turret rotation speed makes acquiring fast low flying targets difficult
* Only 200° total (±100°) of missile launcher rotation
* Max elevation of 35° makes tracking high altitude targets pretty much impossible
* Average mobility with very slow reverse speed
* Unarmoured turret leaves the gunner very vulnerable to knockouts

== History ==


In 1983, the Swedish military gave a contract to Hägglunds and Söner to convert Ikv 102 and Ikv 103 vehicles into Lvrbv 701 surface-to-air missile carriers. The Ikv 102 and Ikv 103, infantry support vehicles mounting a 105 mm gun, had become obsolete in the past few years. At the same time, the same companies were contracted to convert Ikv 102 and Ikv 103 vehicles into Pvrbv 551 anti-tank missile carriers. The hull of the Ikv 102/Ikv 103 was plated over, in order to extend the crew compartment the full length of the vehicle. The engine was replaced by a Ford V-6 engine. The armament consisted of a RBS 70 surface-to-air missile launcher in the center of the hull, which was raised up through a circular opening in the roof of the vehicle - covered by a two piece hatch - in order to fire the weapon.

U26781411: Added history.

{{Specs-Card
|code=sw_strf_9056
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish light tank {{Battle-rating}}. It was introduced in [[Update "Starfighters"]].

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

The '''Strf 9040 BILL''' does not have the MEXAS armour package of the Strf 9040C and Lvkv 9040C, and as such, the protection is very limited. The frontal arc of the vehicle can protect against heavy machine guns but the sides and rear of both the hull and turret are vulnerable even to .50 calibre (12.7 mm) heavy machine guns. The frontal arc can not protect against cannons of even 20 mm in calibre, except on the upper glacis which has a shallow enough angle to cause armour piercing rounds of types other than APDS and APFSDS to ricochet. The turret front and lower glacis on the other hand do not have such angles and can not cause ricochets in the same way, allowing low calibre cannons to penetrate. HEAT and HESH rounds will penetrate the frontal armour without a problem.

The crew placement of the Strf 9040 BILL is both potentially helpful and harmful. A shot to the front left side of the hull would result in the knocking out of the driver, commander, and loader. This is potentially devastating as that is three out of five crew members taken out in one shot, with only one more lost resulting in a vehicle knockout. A shot to the right side of the vehicle's front would knock out the engine and if it had enough penetration would go through and take out the gunner and loader, two out of five crew members but also causing the vehicle to be immobilized. As before stated, the engine can absorb projectiles, preventing them from passing into the crew compartment if they don't have high enough penetration, but it does immobilize the vehicle and potentially allow the enemy to get another shot off immediately afterwards. In terms of ammunition stowage, all 40 mm ammunition is stowed in the base of the turret basket and the hull underneath the turret basket. This prevents most hits from causing a cookoff of 40 mm ammunition except for particularly low hits. On the other hand, the missile stowage is at the rear of the hull and takes up a significant volume, making the missile ammunition a large target. Additionally, the missile launcher has missiles in it which can also be detonated by incoming rounds.

Overall, the Strf 9040 BILL has very light armour and insufficient protection meaning nearly all weapons larger than machine guns can penetrate it. Sometimes the internal arrangement will save from knocking out the vehicle, but most hits will likely be destructive. The upper glacis can block some shots because of the high angle, but this can not be relied upon. Finally, the ammunition stowage - particularly the missile stowage - takes up a large volume of the vehicle and can be set off very easily.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=852|rbMinHp=486}}

As the Strf 9056 lacks the add-on modular armour of the 90C variants, it has a noticeably lighter feel on the move. The low weight combined with high-output Scania engine leads to an agile and swift moving vehicle, able to do sneaky flanking manoeuvres and capable of climbing steep hills to get into ambush positions. When played right, the Strf 9056 is quicker than the Strf 90C, and is able to surprise enemies by showing up in unexpected places.

=== Modifications and economy ===
{{Specs-Economy}}

== Armaments ==
{{Specs-Tank-Armaments}}
=== Main armament ===
{{Specs-Tank-Weapon|2}}


The Strf 9056, like the two other Strf 9040 variants (the Strf 90C and Lvkv 90C), is armed with a Bofors L/70 40 mm anti-aircraft gun repurposed as an omnipurpose (anti-tank, anti-aircraft) gun. The automatic cannon boasts a rapid fire rate, a magazine holding 24 shells, and a complete maximum load of 234 shells. The gun's internal 24-shell magazine is quickly replenished, and is usually enough to deal with both enemy armour, helicopters, and airplanes. It does however carry a risk of surprising the player by running empty - thanks to its high rate of fire. The shells carried are the same as on the Lvkv 90C - the ''spårljuspansarprojektil m/90'' (APFSDS-T), ''spårljusspränggranat m/90'' (HE-T), and ''kulspränggranat m/90'' (HE-VT). The former two are stock shells - the latter is unlocked through research, on the 2nd tier for an RP cost of 18.000, and has a proximity fuze, very helpful against air targets.

The Strf 9056 also carries a 7.62 mm Ksp 39C, coaxial to the main gun, placed in its turret cheek. The most unusual armament is however the Robot 56 "BILL 2 - ''Bofors, Infantry, Light & Lethal''". The dual-missile launcher, mounted on the right side of the turret, can be devastating to enemy armour behind cover. Its missiles fly above the point of aim, detonating above the vehicle, firing its explosively formed penetrator through the turret roof or engine deck, thus hitting areas with the lowest armour protection. A well-aimed hit can destroy a target in a single hit by igniting ammunition, igniting fuel tanks, or knocking out crew. The missiles do however have a limited range of only 2200 meters, and a relatively low speed of 250 meters per second. Used carefully, the vehicle's load of 8 missiles can easily knock out 8 enemy tanks!

== Usage in battles ==


The Strf 9040 BILL is a highly agile fighting machine, it offers great speed and handling. Its relatively small size compared to other tanks on the battlefield allows it to hide and sneak up upon its prey, and equipped with gunner thermal sights the Strf 9040 BILL can easily take advantage and pounce on unsuspecting tankers with the 40 mm Bofors cannon which offers up to 143 mm of penetration per round.

Unfortunately, the 143 mm is not able to penetrate every tank from the front; to overcome this, it is important to disorientate/surprise the enemy tanker. Blind their sights with the rapid-fire from the 40 mm Bofors, then target their cannon so they cannot one-shot at the Strf 9040 BILL like a pen going through a piece of paper.

Once their cannon has been taken out, the enemy tank will retire either using smoke to cover their withdrawal or immediately going to reverse. If they go into reverse without using smoke, knock out their tracks and flank them so their rear compartments can be shot at. The rear compartments (engine bay and further towards the end of the tank) are the weakest. Shooting the engine will cause the engine to catch on fire, then shooting rounds along the side will knock out the crew.

If the enemy tanker reverses, goes over an object in its path and ends up exposing the underside (belly) of the tank, a few rounds targeted in this area from the 40 mm Bofors will knock it out.

One of the key strategic advantages which the Strf 9040 BILL has over its competitors is its [[Rbs 56]] ATGMs. These ATGMs are not like normal ATGMs. Instead, these explode above the target, allowing the blast to penetrate the roof of the enemy tank and knock the crew out. This means when any tank tries to use the terrain or an object to hide, fire the Rbs 56 ATGM towards the target but make sure it's not too high, about 3-5 feet above it, for the best results. If the ATGM is too high when it explodes, the energy from the blast will be reduced and less damage will occur. It should be noted that the missile is already flying above the aiming point in the gunner's sight, so it is not needed to aim above the enemy target except to go over the terrain and cover.

'''Air Threats'''

One of the major weaknesses of the Strf 9040 BILL is its weak armour, this means almost any round can penetrate the tank and knock it out. While it has great mobility, the armour is weak which means air threats can easily destroy this tank. However, it does not mean it's game over. Instead, it's critical to find cover behind buildings to pop out, when the enemy aircraft fires at the Strf 9040 BILL, withdraw behind it. When in the open, pop smoke and stay in the smoke until the threat has gone. It's important to time smoke correctly, the Strf 9040 BILL only has one shot at using it.

* '''Helicopters:''' The best way to find an enemy helicopter is to use thermal sights and scan the air. Once spotted they can then be destroyed with the ATGMs or the 40 mm autocannon with ease. To knock down the helicopter, aim for the cockpit: a few shots will destroy the helicopter. Using the ATGM, either directly hit the helicopter or aim the ATGM slightly above it, utilising the top-attack capabilities of the missile.

* '''Aircraft:''' These are fast, sneaky, and powerful. The easiest time to shoot them down is when they come towards the vehicle or when they overshoot it. However, most of the time it is incredibly unlikely that the Strf 9040 BILL will shoot them down. Instead, it is important to stay alive and not get knocked out. To do this, use the terrain to hide and if that does not work, fire a few shots from the 40 mm Bofors towards them, this will deter them from engaging the vehicle.

=== Pros and cons ===


'''Pros:'''

* Lovely mobility
* Access to deadly top attack missiles, able to destroy enemy tanks hiding behind cover
* Multipurpose 40 mm shells, great for tank side armour and air vehicles
* Access to generation 2 thermals for both gunner and commander - Along with the [[CV 90105 TML]], the BILL is the only Strf 90 that has CITV
* Access to the scouting mechanic
* Wide FOV for the gunner
* Able to fire missiles on the move (albeit at the very slow speed of 5 km/h)
* Missile launchers do not explode when hit by enemy APFSDS shells
* Missile penetrates over 500 mm of steel - no roof of any armoured vehicle can withstand this

'''Cons:'''

* Tanks with ERA on top of the turret (especially Russian tanks) renders the missiles less effective
* Does not have access to the improved Slpprj m/01 APFSDS shell with 170 mm of penetration the [[Strf 9040C]] has
* Unreliable and hull breakable armour
* Two-plane stabilizer disengages at speeds over 10 km/h - The gun then swings violently up or downwards
* It takes time to deploy the missile launcher before the missiles can be fired
* The 40 mm gun chews through ammo very quickly, and replenishing the first stage ammo rack takes time; also only 6 missiles
* Missiles are sensitive to APS - tanks like the AMX-30B2 BRENUS and T-90A can deflect the missile
* Aiming too high above the enemy vehicle ensures the missile does next to no damage to said enemy vehicle
* Missiles are not as effective versus helicopters or spacious tank fighting compartments (like on [[M1A1 Abrams|M1A1]] and [[M1A2 Abrams]])
* Low zoom in the gunsight

== History ==

'''Testing'''

As the Strf 9040 began deliveries in 1998 serious questions were being raised regarding the lethality towards heavily armoured vehicles. Systems like the Bradley IFV and BMP-2 already utilized guided munitions early in their life cycle to combat armoured threats more effectively, something the Swedish IFV had yet to mount. To test the lethality of such weaponry, a demonstrator was ordered in 1999 of the then-current production variant, the Strf 9040A. This vehicle was extensively modified in the fire control system and turret to fit the Rbs 56 BILL II ATGM launcher. The system could fold outwards when engaged and smoothly fold back down when moving, similar to the Bradley. This could all be done from the turret, while reloading had to be done externally by climbing the rear of the vehicle and opening the specialized hatch on the top.

'''Results'''

The 9056 trials seemed promising as lethality was increased. Though issues with sightline visibility plagued the design from the start, forcing a cancellation of the project shortly after. Sweden continued using both systems, although now separate from each other. Both of these systems have seen a lengthy lifespan as the Rbs 56 was retired in 2013, while the Strf 9040 continues being used far into the future.

U26781411: Added armaments image.

{{Specs-Card|code=saab_sk60b}}

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet attacker {{Battle-rating}}. It was introduced in [[Update "New Power"]].

The {{PAGENAME}}, better known as the Saab 105, is a light training vehicle designed for the Swedish army. The vehicle is incredibly light and nimble, and served as ground attacker, thanks to its versatile arsenal of suspended armaments.

== General info ==
The {{PAGENAME}} is one of the more unique planes the Swedish tech-tree offers, especially at the higher ranks. The plane is fairly modern in comparison to jets of the same BR, sporting the same paint-scheme and armament as the much faster [[J35D]]. The {{PAGENAME}} is incredibly small, but with a wide fuselage to accommodate the twin-seat configuration the trainer offers. The wings are mounted in a high-up position, similar to planes like the [[La-15]]. The plane is propelled by two engines that are mounted just outside the fuselage, giving the plane a top speed of just around 800 km/h. The tail is of a T-shape design and works effectively at all speeds, contributing to good manoeuvrability and low stall-speed. Overall the {{PAGENAME}} is a fitting plane for pilots not yet used to jet combat. The plane flies like most piston-engine fighters, lacking in speed but featuring supreme mobility, but also firepower. The {{PAGENAME}} doesn't feature any internal weaponry, but carries two Akan m/55 gunpods, with the same fire rate, burst mass, and positioning as the Draken. This firepower is one of the best at its rank, especially considering the {{PAGENAME}} carries almost twice the ammunition compared to the J35D. Although it's easy to feel godlike with firepower this immense, staying away from fully commit head-on engagements will definitely keep you alive a lot longer, as the {{PAGENAME}} isn't particularly survivable.

=== Flight performance ===

Being a trainer aircraft by nature, the {{PAGENAME}} is very forgiving in aerodynamics. The plane performs ideally at most speeds, and has a stall speed below 200 km/h, allowing for advanced manoeuvring without risking the pilot's life. The rudder and elevators respond quickly, and deflect even at speeds the airframe itself can't sustain. The ailerons are also powerful, allowing the {{PAGENAME}} to smoothly roll in engagements, which along with the other control surfaces, makes it superior in dogfights.
[[File:SK60B Attack Run by D33F.png|left|thumb|420x420px|A pair of {{PAGENAME}}s diving on a target with air-brakes deployed.]]
The flight performance isn't perfect, as the {{PAGENAME}} has obvious downsides from its trainer background. The {{PAGENAME}} is incredibly slow. The plane struggles to break above 700 km/h at most, and will slowly decrease in speed as the fight goes on, as manoeuvres bleeds speed. The {{PAGENAME}} has no real way to gain this speed back either, as the acceleration is sluggish. Although nothing out of the ordinary for early jets, the {{PAGENAME}} doesn't have the top speed to back this up compared to its peers, meaning that most low-altitude dogfights will result in the Saab being the "sitting duck" most of the time. Taking suspended armaments (which is a must) doesn't aid the overall engine performance. Even taking the Akan m/55 gunpods, which are considered aerodynamic, lowers the rate-of-climb significantly, putting it below 20 m/s. Thankfully, the {{PAGENAME}} is classed as an attacker, giving it an altitude spawn of around 1,000 metres. A smart pilot goes for the altitude advantage, as it compensates for any lack of power the {{PAGENAME}} suffers from.

=== Survivability and armour ===

The {{PAGENAME}} is lightweight, and thus forgoes any sort of armour protection to save weight. This decision is logical, as the {{PAGENAME}} was originally designed with only training purposes in mind. This can be experienced in-game, especially in the lack of cockpit protection, as the pilot and navigator will take turns getting killed in frontal attacks. It is thus never recommended to fully commit in a head-on engagement, as even if a pilot survives, the {{PAGENAME}} will become critically damaged, most likely causing it to crash. Even if the {{PAGENAME}} survives, the flight performance is heavily crippled, making the plane even slower than it already was.

Although weak, the {{PAGENAME}} has a few design tricks making its survivability advantageous, one of which is the engine layout. Since the {{PAGENAME}} is a twin-engine design, getting hit in one of these engines isn't considered fatal. The {{PAGENAME}} flies considerably well even using a single engine, making it back to base without any issue. Thanks to engines being slightly external, engine fires don't wound the overall fuselage as much as a single engine mount would. This makes putting out fires a bit easier, as the {{PAGENAME}} can just dive down to the deck with the engines shut off to extinguish it most of the time. The wings are also a strength of the {{PAGENAME}}. Although prone to breaking as the structure isn't particularly strong, the good aerodynamics allow the {{PAGENAME}} to fly despite missing a wing. The plane can also be easily landed after this, as the low stall speed, and robust fuselage, allow for effective emergency landings.

== Armaments ==
=== Suspended armament ===

{{main|Rb05A|m/56D|psrak m/49A|Akan m/55 (30 mm)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 2 x 30 mm Akan m/55 cannons (150 rpg = 300 total)

The standard armament found on the {{PAGENAME}} are two powerful Akan m/55 gunpods. These cannons are identical to platforms like the [[J35D]], giving the {{PAGENAME}} a formidable burst-mass of 12.15 kg/s! These guns are incredibly reliable and fast in velocity, as they're replicas of the [[ADEN (30 mm)|ADEN]] platform. This is one of the main advantages of the {{PAGENAME}} outside of manoeuvrability. Since the {{PAGENAME}} isn't particularly swift, having armament capable of reaching most opponents is a welcome addition. This can catch many people off-guard, and thus it's recommended to practice aiming these guns, along with finding a comfortable convergence setting for maximum efficiency.

These gunpods are also good against ground-based targets, especially in Air Realistic battles, where light pillboxes are common. The Akan m/55 is capable of destroying these in a short burst, allowing for some effective ticket bleed when there are no enemy fighters around. They can also be used in Ground Realistic to a certain extent, as they disintegrate any open-top vehicle. They also aid in air-support, as most fighters at this BR are propeller powered, unable to defend themselves against high-velocity 30 mm revolver cannons.

* 2 x Rb05A missiles

[[File:SK60B using Rb05A's by D33F.png|thumb|345x345px|The {{PAGENAME}} carrying the Rb05A AGM during a roll.]]
The {{PAGENAME}} features a lot of unique armament compared to most other Swedish vehicles. One of the most unique of which are two Rb05A Air-to-Ground missiles. Similar to the American [[AGM-12B Bullpup]] in design and explosive mass, the {{PAGENAME}} goes one step further by featuring a proximity-fuse inside the missile. This makes the Rb05 incredibly unique for its class, as it is the only missile, outside of helicopters, capable of effectively dealing with both aerial and grounded opponents. Since the missile is intended for distanced ground-attacks, the Rb05 features a range of over 8 km, making it useful against long-range bombers such as the [[B-29/Tu-4 (Family)|B-29]]. In Ground battles the missile is even more useful, as the explosive mass of 48 kg allows for reliable kills against ground units without putting the {{PAGENAME}} in front of radar SPAA. And since the Rb05 can be used against aerial opponents, the {{PAGENAME}} can easily deal with helicopters without going back to base.

* 6 x psrak m/49A rockets
* 12 x m/56D rockets

For players more interested in unguided air-support, the {{PAGENAME}} doesn't disappoint! The {{PAGENAME}} features 12 m/56D rockets also found on the J35D. Thanks to the superior aerodynamics of the {{PAGENAME}}, along with a lower battle-rating, the m/56 rockets get a lot more use than on the Draken. The velocity is immense, reaching 650m/s, allowing for accurate and distanced engagements. The m/56D carriers less explosives than the earlier m/49A, but compensates for this by still featuring the same penetration values. This makes the m/56 overall better than the earlier m/49A, as the higher velocity makes engagements a lot easier.

It is important to remember that the {{PAGENAME}} is incredibly vulnerable to SPAA when using the m/56D, as they require the {{PAGENAME}} to position itself close to the battlefield. And since the {{PAGENAME}} is one of the slowest jet-powered aircraft in the game, even machine-gun fire can prove lethal if the plane is flown carelessly. Sticking low to the ground and carefully observing opponents is a must if a pilot wants to make every rocket count.

== Usage in battles ==

'''Air Realistic Battles'''

* Climb to 3,500-5,000 m (11,500-16,500 ft)
* Boom & Zoom opponents
* Conserve ammunition at longer ranges
* Force faster opponents to turnfight
* Prioritize bombers if possible
* Ground strike after dealing with enemy players

The {{PAGENAME}} gets the luxury of spawning at around 1,000 metres from the start, as the plane is classified as an attacker. Just like the [[A-4B|A-4B Skyhawk]], the {{PAGENAME}} can use this advantage to gain the upper hand during the first few minutes of the game. Although many players are purely playing the {{PAGENAME}} for ground battles, diving to the deck will overall limit the {{PAGENAME}}'s success, as the plane has no opportunity to gain speed back at low altitudes. At altitude however, the {{PAGENAME}} can be played more like a piston-engine fighter, using Boom & Zoom tactics to eliminate opponents. This is useful considering the {{PAGENAME}} performs incredibly well at altitude, having a maximum altitude of over 10,000 metres. The {{PAGENAME}} should still try to remain fairly fast, however, as many opponents, such as the [[F-89B]] or [[F-84 (Family)|F-84G]], can easily reach the Saab's altitude by zooming towards it. Keeping the {{PAGENAME}} at a 10° will result in airspeeds around 400 km/h, giving it some room to manoeuvre in case an opponent wants to take care of it. This speed can be maintained for a long time, but keeping the {{PAGENAME}} at an altitude below 5,000m will result in the most efficiency, as most opponents will stay below that threshold. After diving on opponents several times over, the {{PAGENAME}} can afford to be aggressive if the opportunity arises. The {{PAGENAME}} can force most opponents into dogfights, where they have no chance of defeating its superior turn-rate.

If the {{PAGENAME}} gets to face off against the US in a down-tier, it can be recommended to use the Rb05A AGM missile. This weapon system is originally meant for tanks and is indeed highly lethal in ground battles. But a hidden quirk of the missile is a proximity fuse, similar to the [[AA-20 Nord]] found on French aircraft. This is guaranteed to be lethal against planes like the [[B-29A-BN|B-29 Superfortress]], which is commonly found at this BR. The missile works incredibly well against fighters as well, as nobody expects the {{PAGENAME}} to fire a 48 kg warhead in a head-on engagement. The only downside is that the {{PAGENAME}} can only carry two of these, and is completely defenceless afterward. It's more of a fun gimmick at the beginning of a game, but can be quite useful when dealing with the last opponent camping in space.

'''Ground Realistic Battles'''

* Stay close to the ground - This counters SPAA

* Engage ground-units by shooting their compact areas at low altitude (m/56D, m/49/5)
* Attack heavier opponents by gaining altitude before the attack and then swiftly returning to low altitude after the engagement (Rb05A)
* Prioritize helicopters and enemy fighters (Rb05A, Akan m/55)
* Avoid enemy fighters (m/56D, m/49/56)
* Return to base immediately if needed

The most popular use of the {{PAGENAME}} is its intended purpose, known as Close Air Support. The {{PAGENAME}} performs somewhat favourably in this role, being incredibly lethal against tanks since the ordnance options are quite modern for its BR. The {{PAGENAME}} is the earliest example of AGM missiles of any plane in the game, being more than a whole BR below planes like the Fiat [[G.91 R/3 (Germany)|G.91 R/3]], and [[FJ-4B VMF-232]]. Although the Rb05A might look like the obvious option when selecting ground ordnance, the {{PAGENAME}} can easily rack up more kills using the m/56D rockets instead, as they can take out opponents in a single hit, without wasting more than one rocket at a time. This makes the m/56D six times as effective as the Rb05A if practised by an experienced pilot. They are also less dangerous to use, as the unguided rockets don't require any altitude to safely deploy.

When using the {{PAGENAME}} at higher battle ratings, the Rb05A is the most obvious option. Many tanks, especially modern ones, feature advanced protection against chemical explosions, something Swedish m/56 rockets make full use of. The Rb05 AGM missile is a lot more useful here, as no tank can survive a warhead its size, no matter where it impacts. This guarantees the {{PAGENAME}} at least two ground kills, something that can change the tide of the battle at higher ranks, where every opponent is of key importance. Staying low is even more important now, however, as radar SPAA is incredibly deadly at this BR, featuring heavy-calibre cannons and surface-to-air missiles. Only gaining altitude when engaging enemy tanks is important here, as only a few seconds of visibility results in total annihilation by SPAA, as the {{PAGENAME}} is too slow to avoid anything coming towards it.

{{Notice
|When using the {{PAGENAME}} at higher ranks, make sure to prioritize heavy attack helicopters. These can rack up several kills without anyone being equipped to engage them. The Rb05A was designed for this in mind, and can safely engage helicopters over 8km away, thanks to the deadly proximity fuse!

== History ==

'''Background'''

Unlike most aircraft orders from the Swedish Air-Force, the Sk60 has an unusual background compared to its peers. The aircraft initially started as a commercial project under the name 220, led by none other than Eric Bratt, one of the main engineers behind the J35D. The aircraft was supposed to serve as a private airliner, sporting two engines, and a delta-wing design. But in the autumn of 1958, the Swedish Air-Force was looking for a successor to replace the ageing Sk28C Vampire. This led Bratt and his team to rework the design of project 220, switching the delta-wing design for a conventional straight-wing one. When the Air-Force later specified that this trainer had to carry external ordinance in the form of gun pods, rockets, and bombs, the wing was moved to an upper position. A result of this radical change forced a complete reconstruction of the elevator, mounting it higher than before. Along with some tweaking of the cockpit design, the project received the official name Saab 105.
[[File:Saab 105 prototype.png|alt=A black & white image showing the Second Saab 105 prototype mid-flight. The aircraft is mostly unpainted, while carrying civilian markings.|thumb|Second Saab 105 prototype mid-flight]]
The first test flight was conducted in July of 1963, piloted by Karl-Erik Fernberg. The second prototype flew a year later, in June 1964. After some extensive modifying of the air-intakes and wing-structure, the plane was deemed worthy of production. However, during this period the design was going through extensive changes in terms of propulsion, as the French Turbomèca-Aubisque engines (RM9) lacked the required strength. This problem would delay the program another year, but would increase the overall engine thrust.
The third prototype was deemed worthy of service by December of 1965. And by April 1966, the Sk60A would enter service with F5 Air-Division stationed at Ljungbyhed. Disappointingly, the French engines showed a lack of reliability and required a lot of modifying. This issue was however solved by SAAB during the second batch. The deliveries were finalized by 1968.

'''Sk60B'''

The Sk60B was the second modification of the Saab 105. This version, just like the Sk60C, was directly modified from already existing Sk60A's. The Sk60B featured a gunsight, along with the capability of carrying external ordinance in the form of bombs and rockets. The Sk60C went through identical modifications but featured an elongated nose-cone housing a panoramic camera for additional reconnaissance capabilities. Although the early Sk60 only sported a carrying capacity of around 700 kg, the external ordinance allowed for diverse options depending on the mission, capable of dealing with lightly, and heavily armoured targets.

'''Light attack purposes'''

The Sk60B and Sk60C would see extensive use outside the primary training purpose, as on the 29th of May, 1972, the Swedish government decided a reorganization of the Air-Force's attacker divisions. This forced four attack divisions to be converted into four light-attack divisions, making use of the lightweight Sk60B and Sk60C. These would be stationed accordingly at F21, F5, F3, and F16 fighter wing. The Sk60 was light and slow compared to the Viggen platform. The plane operated inland, as the strike capacity wasn't enough for naval operations, aside from small patrol boats and landing crafts. One major advantage of the Sk60 however, was the small profile and good aerodynamic properties, allowing for precise strike operations. This was already realized long before 1972, as F21 Luleå, an air division located alongside infantry and armoured divisions, saw potential in the Sk60 for close air support as early as 1969. This attacker mentality was put into action on all divisions between 1974 and 1976 and would see extensive use throughout the decade. Although the Sk60B was more of a last-ditch vehicle for air support, the plane proved lethal when put against armoured targets and helicopters, as it could remain fairly hidden by flying low against the ground. This strategy was necessary to avoid incoming fire, as the Sk60 featured no countermeasures or modern avionics. But as a result of the twin-seat design, low altitude flying became a lot safer. The pilot could focus entirely on flying as the second seat was occupied by a navigator giving directions. Though a lack of avionics was a major as the Sk60B required full eye-contact with the target to engage it. This limited the plane to only operate during clear weather, and along with a limited range, made the plane less ideal for wartime conditions.

'''Present day'''

The light attack divisions were already getting disbanded by the early 80s, and the light-attack educational program, along with the remaining light-attack divisions, were entirely disbanded by 1998. Although it's easy to determine this as the end for the Sk60, the plane was still a fantastic trainer. The Sk60 went through a major engine overhaul in 1992, doubling its carrying capacity thanks to a much stronger engine. This fixed a lot of reliability issues, and thanks to modern avionics, the Sk60 featured ballistic computers and navigational systems. The Sk60 was projected to be withdrawn from service several times, but thanks to its reliability and flight performance, the Sk60 remains in active use with both the Swedish and Austrian air force, more than 55 years after its introduction. By some estimates, the Sk60 will remain in the Swedish Air-Force until 2030, making the Sk60 older than its numerical designation.

=== [[wt:en/news/6912-development-saab-sk-60b-instructed-to-destroy-en|Devblog]] ===
In 1959, Saab began development of a new twin-engine jet aircraft, intended to serve a wide variety of different roles both in civilian and military use. This led to questions being raised regarding the powerplant choice for the new aircraft, causing delays in development. However, once the decision was made to develop the new aircraft solely for military purposes, the project substantially picked up in momentum.

By 1961, Saab's efforts were endorsed by the Swedish Air Force, which sponsored the development of the aircraft, by then known as the Saab 105, and ordered the production of a prototype in trainer configuration for testing. The prototype took to the skies for its maiden flight in June 1963 and quickly demonstrated excellent handling characteristics. In 1964, the Swedish Air Force placed an initial order for 130 Saab 105's, with that order being raised to 150 machines soon after. The machine received the designation Sk 60 in Swedish service.

During production, the Swedish Air Force drew conclusions from the experiences made by the U.S. forces during the Vietnam War and decided to convert the Saab 105 trainer into a light attack and reconnaissance aircraft. This undertaking proved to be successful, with 60 machines of the trainer version being converted for ground attack missions.

Apart from the Swedish Air Force, Austria also ordered a modified multirole version of the Saab 105 for its air force. Both air forces still employ the Saab 105 to the present day and around 190 units of the type were built in total.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet attacker {{Battle-rating}}. It was introduced in [[Update "New Power"]].

The {{PAGENAME}}, better known as the Saab 105, is a light training vehicle designed for the Swedish army. The vehicle is incredibly light and nimble, and served as ground attacker, thanks to its versatile arsenal of suspended armaments.

== General info ==
The {{PAGENAME}} is one of the more unique planes the Swedish tech-tree offers, especially at the higher ranks. The plane is fairly modern in comparison to jets of the same BR, sporting the same paint-scheme and armament as the much faster [[J35D]]. The {{PAGENAME}} is incredibly small, but with a wide fuselage to accommodate the twin-seat configuration the trainer offers. The wings are mounted in a high-up position, similar to planes like the [[La-15]]. The plane is propelled by two engines that are mounted just outside the fuselage, giving the plane a top speed of just around 800 km/h. The tail is of a T-shape design and works effectively at all speeds, contributing to good maneuverability and low stall-speed. Overall the {{PAGENAME}} is a fitting plane for pilots not yet used to jet combat. The plane flies like most piston-engine fighters, lacking in speed but featuring supreme mobility, but also firepower. The {{PAGENAME}} doesn't feature any internal weaponry, but carries two Akan m/55 gunpods, with the same fire rate, burst mass, and positioning as the Draken. This firepower is one of the best at its rank, especially considering the {{PAGENAME}} carries almost twice the ammunition compared to the J35D. Although it's easy to feel godlike with firepower this immense, staying away from fully commit head-on engagements will definitely keep you alive a lot longer, as the {{PAGENAME}} isn't particularly survivable.

=== Flight performance ===

Being a trainer aircraft by nature, the {{PAGENAME}} is very forgiving in aerodynamics. The plane performs ideally at most speeds, and has a stall speed below 200 km/h, allowing for advanced manoeuvring without risking the pilot's life. The rudder and elevators respond quickly, and deflect even at speeds the airframe itself can't sustain. The ailerons are also powerful, allowing the {{PAGENAME}} to smoothly roll in engagements, which along with the other control surfaces, makes it superior in dogfights.
[[File:SK60B Attack Run by D33F.png|left|thumb|420x420px|A pair of {{PAGENAME}}s diving on a target with air-brakes deployed.]]
The flight performance isn't perfect, as the {{PAGENAME}} has obvious downsides from its trainer background. The {{PAGENAME}} is incredibly slow. The plane struggles to break above 700 km/h at most, and will slowly decrease in speed as the fight goes on, as maneuvers bleeds speed. The {{PAGENAME}} has no real way to gain this speed back either, as the acceleration is sluggish. Although nothing out of the ordinary for early jets, the {{PAGENAME}} doesn't have the top speed to back this up compared to its peers, meaning that most low-altitude dogfights will result in the Saab being the "sitting duck" most of the time. Taking suspended armaments (which is a must) doesn't aid the overall engine performance. Even taking the Akan m/55 gunpods, which are considered aerodynamic, lowers the rate-of-climb significantly, putting it below 20 m/s. Thankfully, the {{PAGENAME}} is classed as an attacker, giving it an altitude spawn of around 1,000 metres. A smart pilot goes for the altitude advantage, as it compensates for any lack of power the {{PAGENAME}} suffers from.

=== Survivability and armour ===

The {{PAGENAME}} is lightweight, and thus forgoes any sort of armour protection to save weight. This decision is logical, as the {{PAGENAME}} was originally designed with only training purposes in mind. This can be experienced in-game, especially in the lack of cockpit protection, as the pilot and navigator will take turns getting killed in frontal attacks. It is thus never recommended to fully commit in a head-on engagement, as even if a pilot survives, the {{PAGENAME}} will become critically damaged, most likely causing it to crash. Even if the {{PAGENAME}} survives, the flight performance is heavily crippled, making the plane even slower than it already was.

Although weak, the {{PAGENAME}} has a few design tricks making its survivability advantageous, one of which is the engine layout. Since the {{PAGENAME}} is a twin-engine design, getting hit in one of these engines isn't considered fatal. The {{PAGENAME}} flies considerably well even using a single engine, making it back to base without any issue. Thanks to engines being slightly external, engine fires don't wound the overall fuselage as much as a single engine mount would. This makes putting out fires a bit easier, as the {{PAGENAME}} can just dive down to the deck with the engines shut off to extinguish it most of the time. The wings are also a strength of the {{PAGENAME}}. Although prone to breaking as the structure isn't particularly strong, the good aerodynamics allow the {{PAGENAME}} to fly despite missing a wing. The plane can also be easily landed after this, as the low stall speed, and robust fuselage, allow for effective emergency landings.

== Armaments ==
=== Suspended armament ===

{{main|Rb05A|m/56D|psrak m/49A|Akan m/55 (30 mm)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 2 x 30 mm Akan m/55 cannons (150 rpg = 300 total)

The standard armament found on the {{PAGENAME}} are two powerful Akan m/55 gunpods. These cannons are identical to platforms like the [[J35D]], giving the {{PAGENAME}} a formidable burst-mass of 12.15 kg/s! These guns are incredibly reliable and fast in velocity, as they're replicas of the [[ADEN (30 mm)|ADEN]] platform. This is one of the main advantages of the {{PAGENAME}} outside of manoeuvrability. Since the {{PAGENAME}} isn't particularly swift, having armament capable of reaching most opponents is a welcome addition. This can catch many people off-guard, and thus it's recommended to practice aiming these guns, along with finding a comfortable convergence setting for maximum efficiency.

These gunpods are also good against ground-based targets, especially in Air Realistic battles, where light pillboxes are common. The Akan m/55 is capable of destroying these in a short burst, allowing for some effective ticket bleed when there are no enemy fighters around. They can also be used in Ground Realistic to a certain extent, as they disintegrate any open-top vehicle. They also aid in air-support, as most fighters at this BR are propeller powered, unable to defend themselves against high-velocity 30 mm revolver cannons.

* 2 x Rb05A missiles

The {{PAGENAME}} features a lot of unique armament compared to most other Swedish vehicles. One of the most unique of which are two Rb05A Air-to-Ground missiles. Similar to the American [[AGM-12B Bullpup]] in design and explosive mass, the {{PAGENAME}} goes one step further by featuring a proximity-fuse inside the missile. This makes the Rb05 incredibly unique for its class, as it is the only missile, outside of helicopters, capable of effectively dealing with both aerial and grounded opponents. Since the missile is intended for distanced ground-attacks, the Rb05 features a range of over 8 km, making it useful against long-range bombers such as the [[B-29/Tu-4 (Family)|B-29]]. In Ground battles the missile is even more useful, as the explosive mass of 48 kg allows for reliable kills against ground units without putting the {{PAGENAME}} in front of radar SPAA. And since the Rb05 can be used against aerial opponents, the {{PAGENAME}} can easily deal with helicopters without going back to base.

* 6 x psrak m/49A rockets
* 12 x m/56D rockets

For players more interested in unguided air-support, the {{PAGENAME}} doesn't disappoint! The {{PAGENAME}} features 12 m/56D rockets also found on the J35D. Thanks to the superior aerodynamics of the {{PAGENAME}}, along with a lower battle-rating, the m/56 rockets get a lot more use than on the Draken. The velocity is immense, reaching 650m/s, allowing for accurate and distanced engagements. The m/56D carriers less explosives than the earlier m/49A, but compensates for this by still featuring the same penetration values. This makes the m/56 overall better than the earlier m/49A, as the higher velocity makes engagements a lot easier.

It is important to remember that the {{PAGENAME}} is incredibly vulnerable to SPAA when using the m/56D, as they require the {{PAGENAME}} to position itself close to the battlefield. And since the {{PAGENAME}} is one of the slowest jet-powered aircraft in the game, even machine-gun fire can prove lethal if the plane is flown carelessly. Sticking low to the ground and carefully observing opponents is a must if a pilot wants to make every rocket count.

== Usage in battles ==

'''Air Realistic Battles'''

* Climb to 3,500-5,000 m (11,500-16,500 ft)
* Boom & Zoom opponents
* Conserve ammunition at longer ranges
* Force faster opponents to turnfight
* Prioritize bombers if possible
* Ground strike after dealing with enemy players

The {{PAGENAME}} gets the luxury of spawning at around 1,000 metres from the start, as the plane is classified as an attacker. Just like the [[A-4B|A-4B Skyhawk]], the {{PAGENAME}} can use this advantage to gain the upper hand during the first few minutes of the game. Although many players are purely playing the {{PAGENAME}} for ground battles, diving to the deck will overall limit the {{PAGENAME}}'s success, as the plane has no opportunity to gain speed back at low altitudes. At altitude however, the {{PAGENAME}} can be played more like a piston-engine fighter, using Boom & Zoom tactics to eliminate opponents. This is useful considering the {{PAGENAME}} performs incredibly well at altitude, having a maximum altitude of over 10,000 metres. The {{PAGENAME}} should still try to remain fairly fast, however, as many opponents, such as the [[F-89B]] or [[F-84 (Family)|F-84G]], can easily reach the Saab's altitude by zooming towards it. Keeping the {{PAGENAME}} at a 10° will result in airspeeds around 400 km/h, giving it some room to manoeuvre in case an opponent wants to take care of it. This speed can be maintained for a long time, but keeping the {{PAGENAME}} at an altitude below 5,000m will result in the most efficiency, as most opponents will stay below that threshold. After diving on opponents several times over, the {{PAGENAME}} can afford to be aggressive if the opportunity arises. The {{PAGENAME}} can force most opponents into dogfights, where they have no chance of defeating its superior turn-rate.

If the {{PAGENAME}} gets to face off against the US in a down-tier, it can be recommended to use the Rb05A AGM missile. This weapon system is originally meant for tanks and is indeed highly lethal in ground battles. But a hidden quirk of the missile is a proximity fuse, similar to the [[AA-20 Nord]] found on French aircraft. This is guaranteed to be lethal against planes like the [[B-29A-BN|B-29 Superfortress]], which is commonly found at this BR. The missile works incredibly well against fighters as well, as nobody expects the {{PAGENAME}} to fire a 48 kg warhead in a head-on engagement. The only downside is that the {{PAGENAME}} can only carry two of these, and is completely defenceless afterward. It's more of a fun gimmick at the beginning of a game, but can be quite useful when dealing with the last opponent camping in space.

'''Ground Realistic Battles'''

* Stay close to the ground - This counters SPAA

* Engage ground-units by shooting their compact areas at low altitude (m/56D, m/49/5)
* Attack heavier opponents by gaining altitude before the attack and then swiftly returning to low altitude after the engagement (Rb05A)
* Prioritize helicopters and enemy fighters (Rb05A, Akan m/55)
* Avoid enemy fighters (m/56D, m/49/56)
* Return to base immediately if needed

The most popular use of the {{PAGENAME}} is its intended purpose, known as Close Air Support. The {{PAGENAME}} performs somewhat favourably in this role, being incredibly lethal against tanks since the ordnance options are quite modern for its BR. The {{PAGENAME}} is the earliest example of AGM missiles of any plane in the game, being more than a whole BR below planes like the Fiat [[G.91 R/3 (Germany)|G.91 R/3]], and [[FJ-4B VMF-232]]. Although the Rb05A might look like the obvious option when selecting ground ordnance, the {{PAGENAME}} can easily rack up more kills using the m/56D rockets instead, as they can take out opponents in a single hit, without wasting more than one rocket at a time. This makes the m/56D six times as effective as the Rb05A if practised by an experienced pilot. They are also less dangerous to use, as the unguided rockets don't require any altitude to safely deploy.

When using the {{PAGENAME}} at higher battle ratings, the Rb05A is the most obvious option. Many tanks, especially modern ones, feature advanced protection against chemical explosions, something Swedish m/56 rockets make full use of. The Rb05 AGM missile is a lot more useful here, as no tank can survive a warhead its size, no matter where it impacts. This guarantees the {{PAGENAME}} at least two ground kills, something that can change the tide of the battle at higher ranks, where every opponent is of key importance. Staying low is even more important now, however, as radar SPAA is incredibly deadly at this BR, featuring heavy-calibre cannons and surface-to-air missiles. Only gaining altitude when engaging enemy tanks is important here, as only a few seconds of visibility results in total annihilation by SPAA, as the {{PAGENAME}} is too slow to avoid anything coming towards it.

{{Notice
|When using the {{PAGENAME}} at higher ranks, make sure to prioritize heavy attack helicopters. These can rack up several kills without anyone being equipped to engage them. The Rb05A was designed for this in mind, and can safely engage helicopters over 8km away, thanks to the deadly proximity fuse!

* Access to attacker spawn
* Long endurance - High fuel and ammo count makes returning to base less frequent
* Decent survivability - It has 2 pilots, can fly without a wing, or without one of the engines
* Easy to land - Low stall speed and strong landing gear aids in critical touchdowns

'''Cons:'''

* Slow top-speed - Unable to catch most opponents it faces
* Weak engines - Loses speed in vertical manoeuvres
* Lack of cockpit protection - Pilot knockout incredibly common in head-on engagements
* Slow acceleration
* Zero integral offensive armament, requiring gun pods
* High repair cost

== History ==

'''Background'''

Unlike most aircraft orders from the Swedish Air-Force, the Sk60 has an unusual background compared to its peers. The aircraft initially started as a commercial project under the name 220, led by none other than Eric Bratt, one of the main engineers behind the J35D. The aircraft was supposed to serve as a private airliner, sporting two engines, and a delta-wing design. But in the autumn of 1958, the Swedish Air-Force was looking for a successor to replace the ageing Sk28C Vampire. This led Bratt and his team to rework the design of project 220, switching the delta-wing design for a conventional straight-wing one. When the Air-Force later specified that this trainer had to carry external ordinance in the form of gun pods, rockets, and bombs, the wing was moved to an upper position. A result of this radical change forced a complete reconstruction of the elevator, mounting it higher than before. Along with some tweaking of the cockpit design, the project received the official name Saab 105.
[[File:Saab 105 prototype.png|alt=A black & white image showing the Second Saab 105 prototype mid-flight. The aircraft is mostly unpainted, while carrying civilian markings.|thumb|Second Saab 105 prototype mid-flight]]
The first test flight was conducted in July of 1963, piloted by Karl-Erik Fernberg. The second prototype flew a year later, in June 1964. After some extensive modifying of the air-intakes and wing-structure, the plane was deemed worthy of production. However, during this period the design was going through extensive changes in terms of propulsion, as the french Turbomèca-Aubisque engines (RM9) lacked the required strength. This problem would delay the program another year, but would increase the overall engine thrust.
The third prototype was deemed worthy of service by December of 1965. And by April 1966, the Sk60A would enter service with F5 Air-Division stationed at Ljungbyhed. Disappointingly, the french engines showed a lack of reliability and required a lot of modifying. This issue was however solved by SAAB during the second batch. The deliveries were finalized by 1968.

'''Sk60B'''

The Sk60B was the second modification of the Saab 105. This version, just like the Sk60C, was directly modified from already existing Sk60A's. The Sk60B featured a gunsight, along with the capability of carrying external ordinance in the form of bombs and rockets. The Sk60C went through identical modifications but featured an elongated nose-cone housing a panoramic camera for additional reconnaissance capabilities. Although the early Sk60 only sported a carrying capacity of around 700 kg, the external ordinance allowed for diverse options depending on the mission, capable of dealing with lightly, and heavily armoured targets.

'''Light attack purposes'''

The Sk60B and Sk60C would see extensive use outside the primary training purpose, as on the 29th of May, 1972, the Swedish government decided a reorganization of the Air-Force's attacker divisions. This forced four attack divisions to be converted into four light-attack divisions, making use of the lightweight Sk60B and Sk60C. These would be stationed accordingly at F21, F5, F3, and F16 fighter wing. The Sk60 was light and slow compared to the Viggen platform. The plane operated inland, as the strike capacity wasn't enough for naval operations, aside from small patrol boats and landing crafts. One major advantage of the Sk60 however, was the small profile and good aerodynamic properties, allowing for precise strike operations. This was already realized long before 1972, as F21 Luleå, an air division located alongside infantry and armoured divisions, saw potential in the Sk60 for close air support as early as 1969. This attacker mentality was put into action on all divisions between 1974 and 1976 and would see extensive use throughout the decade. Although the Sk60B was more of a last-ditch vehicle for air support, the plane proved lethal when put against armoured targets and helicopters, as it could remain fairly hidden by flying low against the ground. This strategy was necessary to avoid incoming fire, as the Sk60 featured no countermeasures or modern avionics. But as a result of the twin-seat design, low altitude flying became a lot safer. The pilot could focus entirely on flying as the second seat was occupied by a navigator giving directions. Though a lack of avionics was a major as the Sk60B required full eye-contact with the target to engage it. This limited the plane to only operate during clear weather, and along with a limited range, made the plane less ideal for wartime conditions.

'''Present day'''

The light attack divisions were already getting disbanded by the early 80s, and the light-attack educational program, along with the remaining light-attack divisions, were entirely disbanded by 1998. Although it's easy to determine this as the end for the Sk60, the plane was still a fantastic trainer. The Sk60 went through a major engine overhaul in 1992, doubling its carrying capacity thanks to a much stronger engine. This fixed a lot of reliability issues, and thanks to modern avionics, the Sk60 featured ballistic computers and navigational systems. The Sk60 was projected to be withdrawn from service several times, but thanks to its reliability and flight performance, the Sk60 remains in active use with both the Swedish and Austrian air force, more than 55 years after its introduction. By some estimates, the Sk60 will remain in the Swedish Air-Force until 2030, making the Sk60 older than its numerical designation.

=== [[wt:en/news/6912-development-saab-sk-60b-instructed-to-destroy-en|Devblog]] ===
In 1959, Saab began development of a new twin-engine jet aircraft, intended to serve a wide variety of different roles both in civilian and military use. This led to questions being raised regarding the powerplant choice for the new aircraft, causing delays in development. However, once the decision was made to develop the new aircraft solely for military purposes, the project substantially picked up in momentum.

By 1961, Saab's efforts were endorsed by the Swedish Air Force, which sponsored the development of the aircraft, by then known as the Saab 105, and ordered the production of a prototype in trainer configuration for testing. The prototype took to the skies for its maiden flight in June 1963 and quickly demonstrated excellent handling characteristics. In 1964, the Swedish Air Force placed an initial order for 130 Saab 105's, with that order being raised to 150 machines soon after. The machine received the designation Sk 60 in Swedish service.

During production, the Swedish Air Force drew conclusions from the experiences made by the U.S. forces during the Vietnam War and decided to convert the Saab 105 trainer into a light attack and reconnaissance aircraft. This undertaking proved to be successful, with 60 machines of the trainer version being converted for ground attack missions.

Apart from the Swedish Air Force, Austria also ordered a modified multirole version of the Saab 105 for its air force. Both air forces still employ the Saab 105 to the present day and around 190 units of the type were built in total.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

The {{PAGENAME}} is the first Swedish jet capable of Mach 2. The jet is highly agile and is the first plane in War Thunder capable of performing the famous "Cobra manoeuvre".

== General info ==
=== Flight performance ===
[[File:J35D profile D33F.png|alt=A saab draken flying through thick overcast with a sunset illuminating the clouds below it.|left|thumb|460x460px|A {{PAGENAME}} flying above cloudy weather.]]
The Saab {{PAGENAME}} Draken is a highly agile interceptor of the Swedish aviation family. This interceptor uses a double delta wing-configuration and a powerful Avon engine to achieve both excellent high and low-speed performance at various altitudes. This aircraft is outfitted with two wing-mounted Akan m/55 auto-cannons and up to four [[Rb24|RB24]]/[[RB24J]] missiles. Along with options for both anti-air and anti-ground rockets, the {{PAGENAME}} becomes a versatile platform with a high potential thanks to unmatched maneuverability. Having almost twice the wing surface of a [[MiG-21MF (Germany)|MiG-21MF]], the {{PAGENAME}} comfortably dogfights any opponent who dares to challenge it.

The cost of this maneuverability is the large reduction in speed when turning. The {{PAGENAME}} usually drops below 500 km/h airspeed when performing aggressive maneuvers. This lack of speed usually leaves the {{PAGENAME}} vulnerable to enemy attacks, since avoiding missiles or gunfire becomes a lot more difficult. This makes the {{PAGENAME}} a unique flying experience where the player needs to be constantly aware of the current airspeed, while still avoiding dumping all speed at once. In order to maximize the stored speed, the {{PAGENAME}} should be flown carefully. Aerial maneuvers should be avoided and turning has to be done slowly. The efficiency of the {{PAGENAME}} significantly increases when played with higher speeds. Although the plane becomes more sluggish at speeds close to 1,100 km/h, the {{PAGENAME}} still manages to outmaneuver incoming missiles. Avoiding incoming homing devices usually leads to deceleration, but with careful planning, this speed can always be regained thanks to the strong acceleration the engine provides.

=== Survivability and armour ===

[[File:J35D protection.jpg|thumb|400px|right|The '''{{PAGENAME}}''' forgoes armour for additional speed and manoeuvrability.]]

The {{PAGENAME}} is one of the many high-rank planes entirely without protection, much like the [[F-4 Phantom II (Family)|F-4 Phantom]] series of fighters. Although the later variants of the Draken featured bird strike-proof cockpits, no Draken variant was fitted with armour plating or bulletproof glass. In-game, this downside can be quite hard to notice since higher rank vehicles tend to boast incredible amounts of firepower, making every hit incredibly devastating. A {{PAGENAME}} pilot should, like every other pilot, avoid damages at all costs as any damage deteriorates the aircraft's performance and ability to stay in the fight.

== Armaments ==
=== Offensive armament ===

{{main|Akan m/55 (30 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 2 x 30 mm Akan m/55 cannons, wing-mounted (90 rpg = 180 total)

The {{PAGENAME}} is outfitted with two 30 mm Akan m/55 cannons, which are Swedish manufactured variants of the British [[ADEN (30 mm)|ADEN]] cannons. These two cannons offer a high burst mass and velocity at medium ranges. Although these guns are dangerous, they are quite limited by their ammunition count. Just like the J32B, these cannons have 90 rounds each, giving the player a total of 180 shells. The cannons should be fired with caution in order to maximize the amount of damage they provide. Since the missiles are outdated RB24 missiles, a {{PAGENAME}} pilot needs to be prepared to engage most enemies with these cannons rather than suspended armaments.

Another issue with the {{PAGENAME}} is the cannon placement. The two Akans are wing-mounted rather than center-mounted. This is a downgrade compared to the gun placement found on the earlier J32B since set convergence now plays a role. This makes the {{PAGENAME}} lose effectiveness at certain ranges since the target has the chance to fly between the shells, and when hitting a target, the shells are unlikely to concentrate to a singular point, lowering the amount of damage created. This placement creates difficulty in complex maneuvers, since putting the plane sideways creates a vertical spread. A wise {{PAGENAME}} pilot will commence target practice with the guns prior to battle as they are important for the plane's overall survivability and combat effectiveness.

=== Suspended armament ===

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 12 x m/56D rockets
* 38 x srak m/57B rockets
* 4 x RB24 missiles
* 2 x RB24 missiles + 12 x m/56D rockets
* 2 x RB24 missiles + 38 x srak m/57B rockets

{{main|m/56D}}

The {{PAGENAME}} is able to carry 12 suspended m/56D unguided rockets for ground-strike purposes. These rockets have a TNT filler with the same penetration as the earlier [[m/49A]] found on the earlier ground-strike planes. The rockets fire individually starting from the left, and are placed in a vertical angle, These rockets are devastating against lighter vehicles at high tiers. Thanks to a single-fire system and good velocity, the effectiveness can be quite high if practiced. But due to the {{PAGENAME}} being only available for use at top-tier, these rockets have a very low chance of reliably working, since the targets are usually heavily armoured. The {{PAGENAME}} lacks a ballistic missile computer and is easily countered by missile SPAA, making the {{PAGENAME}} a bad pick for close air support in general. If the player feels the need for a challenge, the {{PAGENAME}} is at the very least highly maneuverable, giving players the option to do several dangerous passes in a short period of time.

{{main|srak m/57B}}

The {{PAGENAME}} offers a pair of unguided m/57B rocket pods. These rockets are designed for bomber interception, and are very devastating against aerial targets. These rockets fire in pairs, in contrast to the single-fire m/56D rockets for ground-attack purposes. Being placed parallel with the plane, these rockets are comfortable to aim due to the traditional angle, as well as the center fuselage mounting they offer. These pods weigh less than the full RB24 loadout, but still require a {{PAGENAME}} pilot to engage targets the same way as with the internal Akan m/55 cannons, making them quite redundant. These pods are for pilots looking for a challenge, while still staying effective in aerial combat.

{{main|Rb24}}

A later modification found on the {{PAGENAME}} is the option to carry four RB24 missiles, the same being found on the previous J32B Lansen. These missiles are mounted separately from each other, with two under the center fuselage, and two under the outer delta. Having four of these missiles significantly lowers the performance of the {{PAGENAME}}, meaning that more aggressive players should consider if they will find a practical use for this suspended armament. Defensive and more cautious players will, however, enjoy these missiles since they offer a more distanced approach to engaging targets. A pilot should still be aware that these missiles tend to miss most opponents at high-tier due to missile countermeasures, as well as higher speeds and maneuverability found at these tiers.

''Main article: [[RB24J]]''

The crown jewel of the {{PAGENAME}}'s modifications are the four RB24J air-to-air missiles carried under the same pylons as before. These missiles have twice the G-load and a wider seeker, giving it a lot more flexibility than its older counterpart. Thanks to their supreme mobility, they can easily engage and destroy close opponents with minimal effort. This feature is incredibly helpful for the {{PAGENAME}}, since most engagements forces the plane to slow down. The RB24J air-to-air missiles allows the {{PAGENAME}} to close the gap between the enemy and itself, no matter the difference in speed, making it one of the most important tools in the {{PAGENAME}}'s arsenal. This missile is heavily recommended for any pilot that wants to make the most out of their own Draken.

== Usage in battles ==

The {{PAGENAME}} can be a bit "over the top" when it comes to in-game performance. The {{PAGENAME}} doesn't underperform in any area, even when stock. Yet the {{PAGENAME}} quickly suffers when facing several opponents at once. This is due to the incredible maneuverability the {{PAGENAME}} possesses, which becomes its worst enemy in battles. The {{PAGENAME}} comfortably dodges incoming enemies when at higher speeds, but quickly loses this advantage after the first few passes due to the reduction of speed. Avoiding can still be done easily, but high-load missiles require a speed above 800 km/h to be reliably dodged. To avoid the likelihood of a low-speed experience, the {{PAGENAME}} should maneuver with caution, with the same style as a pilot preventing wings from ripping. The recommended way to use this trick is to control the elevators with the use of the "pitch axis" button. By tapping this button rapidly, a {{PAGENAME}} pilot can prevent high-G maneuvers while still keeping their backs cleared by looking behind them in a defensive-like approach. The amount of pulling can be varied depending on what is approaching the Draken. It's important to remember that aileron rolling can still be done without much consequence, and will come in handy when avoiding enemies in a defensive situation.

'''Attacking while using the Akan m/55'''

When the {{PAGENAME}} isn't on the receiving end of an attack, the dominating maneuverability and acceleration start to show. The Draken has the ability to stick with almost any enemy. A rude, but effective approach is to engage already slow enemies since the Draken will never overshoot a target. This should also be done with caution since this is still a sacrifice of valuable energy required to avoid incoming attacks. Learning when to strike is key for the {{PAGENAME}}, since staying alive is always a number one priority.

When it comes to firing on a target, the {{PAGENAME}} immediately shows it's unorthodox gun placement. Shooting opponents running away, or firing on bypassing enemies might often result in the {{PAGENAME}} missing the target entirely. To avoid this, a pilot can both train their aim and learn useful aerial maneuvers to increase the likelihood of hitting opponents. A general tip when firing upon passing opponents is to make the enemy pass the {{PAGENAME}} along its horizontal axis. This ensures that the target passes through both guns, and the time on target automatically increases. Although this tactic won't focus as much lead on a singular point as a regular approach, it will still assure some shells connect with the target, which is usually enough to finish off any opponent.

'''Attacking while using the RB24 and RB24J'''
[[File:J35D intercept by D33F.png|alt=A J35D, shadowed by sunlight, climbs above the clouds to intercept.|thumb|420x420px|A shadowed {{PAGENAME}} climbing to intercept. ]]
The missile gameplay favors altitude and separation over head-on engagements and dogfights. Thanks to the {{PAGENAME}}'s performance, the plane can easily flank to the side or reach incredible altitudes while keeping a safe speed. Catching enemies off-guard can be quite difficult, but trying to stay off the radar lock function (keeps you hidden from RWR), is a good start. The early RB24 missiles have no real use of Radar locking, while the RB24J's improve significantly from this function. Avoid locking them until you're in a close proximity to the target. The more speed you have compared to the target also affects the result. A slower opponent has less time to react, while a faster one has extra time and usually agility to avoid incoming homing devices. It's important to know which planes you're attacking and when they're vulnerable to incoming attacks. Even if the missile doesn't hit, the {{PAGENAME}} can easily catch up with the enemy due to their slower speed afterwards. It's important to still make good use of the Akan m/55 while playing with suspended armament. These missiles can effectively help close the distance between the {{PAGENAME}} and its target, where gunfire is ideal. This also spreads out the missiles between opponents, letting the {{PAGENAME}} rank up more kills when played strategically.

'''Superstalling'''

The {{PAGENAME}} features one of the largest wing-areas of any fighter. Although this gives the {{PAGENAME}} a high advantage in terms of manoeuvrability and speed, the plane suffers from a unique, but dangerous downside. This downside becomes apparent when damaged, stalling, or deploying negative elevator for a extended period of time. This feature is known as a "superstall", and can result in complete destruction of the aircraft. A superstall can be noticed by the parachute-like falling the plane experiences. The plane spins, and can't exit the manoeuvre for a extended period of time. In order to exit a superstall, the {{PAGENAME}} is outfitted with four tiny air-brakes positioned at the rear of the aircraft. Deploying these air-brakes will pull the tail-section upwards, allowing a {{PAGENAME}} pilot to regain airflow under their wings. It's important to avoid superstalling since the {{PAGENAME}} stays incredible vulnerable during this period.

=== Pros and cons ===


'''Pros:'''

* Superior manoeuvrability - able to out-turn anything it wishes
* High top speed - can catch most top tier aircraft at low altitudes
* Strong acceleration
* Easy and short takeoff/landing
* Low stall speed - air-brakes prevent "superstalling"

'''Cons:'''

* Poor sustained turning - sustained speed degenerates quickly when manoeuvring at speeds below 1,000 km/h
* Unorthodox gun placement - less accurate and more tricky to get used to
* Lack of countermeasures - no flares or RWR
* Sluggish performance when paired with suspended armaments
* Relatively low maximum fuel load, can make it vulnerable in case of prolonged engagements

 
{{Notice|'''Fun Fact''': Pilots of the {{PAGENAME}} created a term called '''superstalling''', unlike typical aircraft which would stall, nose over, and recover, the Draken's control surfaces remain ineffective for some time as the aircraft falls, potentially causing it to crash.}}

== History ==


;Background

The discussion about a new fighter project, capable of intercepting small groups of bombers at an altitude of 10 kilometres, was brought up in the autumn of 1949, just a few months from the introduction of the [[J29A|J29 Tunnan]]. The threat was deemed to be transonic bombers, which needed to be intercepted before reaching Swedish airspace. This meant the next big project, Saab would focus on a high-speed interceptor capable of exceeding the Mach number, while still being able to function as an all-weather, daytime fighter.

;Saab 210 Lilldraken

This new project for a supersonic fighter-interceptor was given the name "project 1200". This project would be lead by the Saab engineer Erik Bratt. His team tinkered with various ideas on how to create a supersonic fighter with low-speed handling, to ease landing on shorter runways. The team came up with a double delta design that made use of two wing angles, giving the plane less drag at higher speeds, while staying maneuverable at lower speeds. In order to test this design, the team constructed a miniature version of the new fighter, named Saab 210, which also received the nickname "Lilldraken" (translates to small kite). This plane was just 70% the size of the regular Draken and was used for extensive testing of handling as well as ergonomics of a double delta configuration. This prototype was first flown on January 21st, 1952.

The Saab 210 would see many changes to its design in order to finalize the look of the upcoming J35 Draken. The nose was changed to better suit radar use, its air intakes moved back for a better view, and the tail reconstructed to fit a drag-chute. All of which would be found on the J35 Draken later on.

;Saab 35 Draken

[[File:Saab 35 Draken prototypes.jpg|thumb|Two prototype Saab 35 Draken flying in formation.]]
With the tests finished, the Draken would finally see full-scale prototypes. The first prototype took to the skies in October 1955, and deliveries of the first variant, the J35A, would commence in 1959. By 1960 the first Drakens would officially be in service. These would be stationed at F13 Bråvalla and F16 Gotland. Later variants would be placed all over Sweden, with various purposes. Being used for bomber interception, reconnaissance and trainers, the Saab 35 Draken would see the longest service life of any fighter in the Swedish air force. The Draken would serve for almost 40 years, having 615 planes produced during its lifespan.

;{{PAGENAME}} Draken

The {{PAGENAME}} was the 4th Draken variant that was planned and built due to the new requirements the Swedish KFF (Kungliga FlygFörvaltningen or Royal air ministry) issued to Saab. The new requirements specified that the next fighter had to intercept high altitude bombers flying at Mach 1.5, while still carrying the same weaponry and ordinance the earlier J35B offered. This required Saab to upgrade the RM6B engine found on the J35B, which meant the design had to be slightly altered. The air intakes were elongated, and the fuselage got altered to support the use of drop-tanks in the center. The first {{PAGENAME}} took to the skies on the 28th of August 1962, but the first planes delivered would be without radar equipment. These would be known as the J35D1, of which 24 of which were made. The other planes got the name J35D2 and would later be known as the {{PAGENAME}} when the original D1s got their radar equipment installed.

A total of 120 {{PAGENAME}} Drakens would be built between 1963-1964. Being outfitted with the Rm 6C (Avon 300-series), this version was the fastest Draken to take to the skies. This Draken would also be exported to the Austrian air-force. In order to export these planes to Austria, Saab ended up buying back 24 of the Swedish serving {{PAGENAME}}s and converting them to the Austrian requirements, which meant fitting the planes with the bird-proof cockpit from the J35F, as well as repainting them for Austrian service. These Austrian Drakens, designated J35Ö (sometimes designated J35OE), saw extensive use all the way towards the 21st century, being taken out of service in 2005.

=== [[wt:en/news/6623-development-saab-j35d-draken-the-supersonic-kite-en|Devblog]] ===
In the late 1940s, the Swedish Ministry of Defence released a set of requirements for a new, cutting edge jet interceptor. Among other requirements, the new aircraft was to be capable of reaching speeds of Mach 2 and able to hunt down transonic bombers, while being easily maintained and capable of taking off from special public roads.

Saab began developing an aircraft around these specifications in the early 1950s and quickly came to the conclusion that a double delta wing design was needed in order to achieve all the requirements. However, this design was yet untried and untested, which led to the creation of the Saab 210 - a testbed aircraft which pioneered the double delta wing design.

Having gained the necessary insight on the performance of the double delta wing, Saab engineers transferred the newly acquired experience into the development of the actual aircraft to address the Ministry’s requirements - the J35 Draken was born.

The J35 Draken undertook its maiden flight in October 1955 and entered service with the Swedish Air Force in March 1960. Over 650 Drakens of various modifications would be built until the end of production, serving with Sweden until the late 1990s before being decommissioned. Apart from Swedish service, the J35 Draken also saw use with Denmark, Finland and Austria. The Austrian Air Force was the last operator to decommission the Draken in 2005, while some units are still in civilian use.

The J11 is a rank one Swedish fighter with 2x 12.7mm Akan m/40 machine guns, which are devastating when they hit an enemy bib-plane but they have a slow firing rate. The plane has a high top speed which can outrun most biplanes at its rank, when fully upgraded.

{{main|Akan m/40 (12.7 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 2 x 12.7 mm Akan m/40 machine guns, nose-mounted (450 rpg = 900 total)

== Usage in battles ==
'''Realistic Battles'''

* Climb slightly to avoid large dogfights
* Dive on unsuspecting opponents
* Keep altitude and turn only when necessary

The {{PAGENAME}} plays identical to the Italian counterpart, capable of high speeds without sacrificing the agility a biplane offers. The engine is almost twice as powerful compared to the [[J6B]] found before it, and the strong framework allows for even higher speeds, allowing the {{PAGENAME}} to chase down opponents in battle. Most importantly, however, is that the {{PAGENAME}} offers greater climb and energy retention, allowing for a bit more boom & zoom compared to other biplanes. The {{PAGENAME}} turns a bit worse than other biplanes, which is logical considering the powerful engine and heavy steel structure it features. This makes extended dogfights against other biplanes difficult, but should be avoidable by most {{PAGENAME}} players if speed is kept at an all-time high.

One large downside to this {{PAGENAME}} is the firepower. The Akan. m/40 are identical to the Italian guns found on the [[CR.42 (Family)|CR.42]]. Although the caliber is of 12.7mm, the Italian guns are quite lackluster in performance due to the ammunition used. This requires the {{PAGENAME}} to put a lot of gun-time down compared to planes such as the [[J8A]], which is incredibly potent at dealing with biplanes. The guns are still have some tricks up their sleeve, especially when it comes to wing, and engine damage. The .50 caliber ammunition can spread damage effectively, allowing for high wing-root damage, and the higher penetration and caliber size allows for additional damage to engine components, which are crucial at this BR.

{{Notice|The landing brakes used by the {{PAGENAME}} are incredibly powerful and puts the plane at risk of nosing over due to the heavy engine. Make sure to gently tap the brakes at lower speeds, in order to prevent the plane from potentially crashing!}}

== History ==

The J11, also known as the Fiat C.R.42, is an Italian-made fighter that was bought and maintained by the Swedish Air force "Svenska Flygvapnet" in the late 1930's. As World War 2 broke out, the Swedish air force felt the necessity to increase its air defence and yet due to the ban on exporting weapons and war machines during the war the Air force was relying on older and less capable fighters. When Italy showed interest in selling the Fiat C.R.42 the Air force placed an order of 120 planes and named the aircraft "J11". While the plane was mainly used as a fighter, it could also serve as a scout/recon vehicle. During the war the J11 was already outdated and could not withstand the superior german fighters and it was made with poor quality forcing most of the aircraft to become scrap metal. Today, few stand unharmed or restored and are located in aircraft museums around Sweden.

{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].

The J28B is an early Cold War jet known as the [[Vampire FB 5]] in the British tech tree. It was ordered in large numbers by the Swedish air force to leap into the jet age. The Vampire family is known for its great dogfighting capabilities, meaning the J28B can comfortably fend off several opponents at once if controlled by a skillful pilot. This aerial performance is given at the cost of engine power.

== General info ==
=== Flight performance ===

The J28B performs well at low altitude where it easily outturns most opponents it faces. Thanks to the excellent flaps and air brakes, a pilot aware of his/her energy can fend off anyone that picks a fight. The flaps can be utilised at various speeds to outturn any enemy at any time. Dogfights are where the Vampire platform shines, it is a highly effective fighter with its relatively light airframe and smooth controls. Although the power is lacklustre, a pilot aware of his/her surroundings will have no difficulty avoiding incoming enemies. This lack of engine power will, however, cripple the J28B when it comes to acceleration. A Vampire tends to lose a lot of speed when engaged in turning. So gaining it back to defend itself against new opponents becomes a hassle. And even if a J28B pilot manages to get their speed up, catching a target will be close to impossible with a slow top speed. This lack of power hinders the J28B in many ways, mostly related to energy. This is why "Vamp" pilots are advised to climb at the beginning of a match, despite the lack of a decent climb rate.
[[File:Rocket J28B.png|thumb|The Aiming reticle of the Swedish m/51 rockets.]]
The J28B performs identically to the Vampire FB 5 which should not come as a surprise. The firepower is what makes them different, however. The J28B is outfitted with the Swedish Akan m/47B (short for "Automatkanon"), which is the Swedish designation of the British Hispano Mk.V, although the calibre and fire rate are the same, the burst mass is larger. This has to do with the Swedish ammunition. The Swedish ammo type contains more TNT and is fully tracer equipped, meaning stealth isn't an option. Despite this downside, the guns perform closer to the American AN/M3 guns instead of the British Hispanos, making the J28B the most effective Vampire in regards to firepower. The J28B is also outfitted with several types of anti-tank and anti-ship rockets. Despite lacking the large 1,000 lb bombs the FB 5 offers, the rockets offer a much different experience compared to the original model. The rockets fire one at a time held on by a Swedish rocket rack, pointing them further down than usual. The average pilot, especially the ones coming from the FB 5, will find this new placement tricky to get used to. But considering the single fire system, a skilled pilot might be able to rack up more destroyed tanks in ground battles compared to the FB 5. If this becomes too sufferable, however, it is recommended to use "Fire rocket salvo" instead to fire off two rockets at once, for a more traditional feel. It's not worth sacrificing accuracy for efficiency when it comes to rockets.

=== Survivability and armour ===


* 38 mm Bulletproof glass - Armoured windscreen
* 12.7 mm Steel - Armour plate behind the pilot's head
* 3 mm Steel - Armour plate under the engine

[[File:Armour values J28B.png|thumb|Armour found inside the J28B]]
The J28B has the same armour as the Vampire FB 5 as well as the Italian [[Vampire FB 52A]]. Despite being dangerous in a head-on due to the beefed-up guns, a J28B should never fully commit to a head-on engagement, the bulletproof glass will, however, save the pilot most of the time. The tail section is not easily saved though. The twin-boom makes it twice as likely to hit the traction of control surfaces. This leaves the J28B completely useless usually resulting in abandonment of the aircraft, which should be avoided at all costs.

== Armaments ==
=== Offensive armament ===

{{main|Akan m/47B (20 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 20 mm Akan m/47B cannons, chin-mounted (150 rpg = 600 total)

The 20 mm m/47B cannons found on the {{PAGENAME}} are fairly unique, as it's the only vehicle in the game carrying this specific version. The gun is identical to the British [[Hispano Mk.V (20 mm)|Hispano Mk.V]] found on the [[Vampire FB 5|British Vampire]]. Ammunition count and fire-rate are identical, but the belt composition differs. While the British guns use shells that lack tracers, along with less explosive, the Swedish HEF-T, and AP-T are the only two rounds available, resulting in every round being visible. This can seem overwhelming, but considering the amount of damage the {{PAGENAME}} deals in a single burst compared to the Hispano, the trade-off is worth it.

=== Suspended armament ===

{{main|hprak m/49|psrak m/49A|srak m/51}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 8 x psrak m/49A rockets

The {{PAGENAME}} is incredibly feared in ground-battles due to the devastating m/49A rockets it carries. These rockets lack a high explosive-mass, especially compared to high-explosive rockets similar to it, such as the British [[RP-3]]. However, the Swedish rocket works more in a shape-charge matter, giving it high penetration values, and post-penetration damage. This means the {{PAGENAME}} is more likely to ammo-rack opponents than similar analogs, as the {{PAGENAME}} can engage opponents from any angle it wishes

* 8 x srak m/51 rockets

Although visually indistinguishable from the m/49A, the m/51 rockets are very different in behaviour from their older counterpart. These rockets are high-explosive, similar to how the British RP-3 behaves. The rocket lacks significant penetration, even when compared to the RP-3, making them quite redundant against tanks. They can be effectively used against lightly armoured vehicles, however, as the explosive spreads more towards the side rather than just forwardly. The rockets can also be used against aerial opponents, especially bombers. Since this rocket has a 10 m/s faster travel-speed compared to the m/49A before it, they're slightly more useful when applied against aerial targets, even if they're less than ideal for this purpose.

* 4 x hprak m/49 rockets

The final rocket modification found on the {{PAGENAME}} are the large 18 cm m/49 hprak. Compared to the shaped charged m/49A, and the high-explosive m/51, these rockets are actually SAP (Semi-Armour Piercing), making them very unique for their type. Due to their size, the {{PAGENAME}} is only able to carry four. The rockets are fired differently from other types as-well, especially compared to conventional rockets that ignite before leaving the pylon. These rockets ignite like the American [[Tiny Tim]] rocket, in which the propellant is only ignited after leaving the pylon, giving it a bit of a delay before engaging. This makes them tricky to aim, and since they barely have 10% of the explosive found inside the American counterpart, they're very ineffective against tanks.

{{Notice|The {{PAGENAME}} features a rocket-rack pointing all suspended weapons ~5° downwards. This forces pilots to fly the plane horizontal to avoid missing the target but allows the {{PAGENAME}} to engage tanks without pointing its nose down a lot.}}

== Usage in battles ==
'''Air Realistic battles'''

* Minimum fuel or 20 minutes - depends on map size
* Ground targets for 20mm belts
* Climb slightly at ~10°
* Boom & Zoom opponents, dogfight when necessary

A J28B pilot should always be aware of his/her speed and altitude, or energy in more advanced terms. To avoid enemies with superior engine power using it as a boom and zoom target, a J28B pilot should use altitude to their advantage. Since the Vampire platform is bad at building up energy, the pilot should store as much energy as possible for when the battle begins. Before engaging targets, it can also be useful to always keep a speed of at least 400 km/h to limit the number of options an enemy has to counterattack. This also helps the J28B to swiftly turn around and begin a dogfight if the opponent commits to one. This play-style can be applied to every Vampire plane in the game since they perform mostly the same. The J28B has to watch out for [[Ho 229 V3]] players, however, since they can outmatch the J28B in turning. A good way to counter the Horten is to make it bleed speed. Forcing it to turn once or twice and then extending away from the enemy.

A play-style close to that of a propeller-driven aircraft can be applied, where energy is the key to survival. The J28B has quite the firepower compared to the other Vampire models. This can reward players who can safely head-on from a distance and then avoid incoming shots from the enemy. This will usually result in a critical hit or straight-up destruction if the enemy doesn't also avoid. The fired rounds are quite deadly and require less gun-time compared to the British counterpart. This gives the J28B an overall higher chance of surviving since it can afford to spend less time on each target. A pilot comfortable with their aim will easily outsmart opponents and make them think twice before engaging in a future dogfight with a {{PAGENAME}}.

'''Ground Realistic battles'''

* Minimum fuel, 8 x m/49A rockets
* Ground targets for 20mm belts
* Attack opponents from low altitude
* Prioritize aerial opponents

The {{PAGENAME}} is the ultimate CAS plane for Sweden at the BR range it sits at. The Vampire platform is incredibly maneuverable which allows for safe attacks against ground targets, and the high agility is incredibly helpful against propeller-driven opponents. Equipping eight m/49A rockets does hinder the performance slightly, but are one of the most lethal rockets found at this BR. Thanks to them being a tier I modification, having a potent {{PAGENAME}} isn't difficult to achieve. Make sure to engage targets at low altitude, avoiding any form of SPAA, as the {{PAGENAME}} is required to fly straight during approaches, due to the difficulty of aiming. Make sure to aim the m/49 rockets in tightly packed crew compartments, and ammunition stowage, similar to how you would typically fire a HEAT-FS round. This is why broadside engagements are more effective, as having a larger target profile allows for increased accuracy.

The rockets aren't the only thing the {{PAGENAME}} makes use of. The 20mm cannons have plenty of ammunition and allow the plane to deal with SPAA from longer distances. The ground-targets belt penetrates most SPAA, allowing the {{PAGENAME}} to save the m/49A rockets for tanks instead. The guns are capable of damaging engine decks, especially on tanks such as the British [[Centurion (Family)|Centurion]] or German [[Panther tank (Family)|Panther]]. Against aerial targets the {{PAGENAME}} performs ideal as always, damaging most opponents in a single spray. Always make sure to deal with these opponents first, as even if they pose no threat to the {{PAGENAME}}, they most definitely threaten its teammates.

== History ==

The Swedish air force carefully studied what was happening at the Fronts in WWII, and by 1944 it was already obvious that the propeller era was coming to a close. By early 1945, the Swedes had already begun a project to power the Saab J21 with a ramjet. However, it seemed this project would take far too long. By autumn of 1945, the J29 project was also beginning to take shape. But even this project wouldn't take to the skies until 1949, so a foreign design had to do until then.

The British de Havilland Vampire was one of the first jet-powered fighter planes to enter the market, and Sweden was very interested in this design. In early 1946, Sweden ordered 70 Vampire F Mk 1 models designated J28A, thus becoming one of the first customers of the Vampire. This version was mostly used as practice for the new era of jet-driven aircraft. But the Swedes became fond of the design. So when the export version of the Vampire FB 5 entered the market known as the Mk 50, Sweden was very interested and orders started in 1949. This version was to be known as the J28B or A28B depending on suspended armaments. This version differed from the Mk 1 by having a renewed, rounder tail section, and a lower placed elevator. The engine was upgraded from the RM1 to the RM1A that was now produced by SFA (Svenska flygmotor AB) in Sweden and delivered to de Havilland in Britain for installation. The main armament was also changed from the Hispano Mk II to the more potent Hispano Mk V. By 1952, 310 J28B Vampires had been delivered to Sweden. 12 of these would be rebuilt as a two-seat trainer, known as the J28C-3.

{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].

The J28B is an early Cold War jet known as the [[Vampire FB 5]] in the British tech tree. It was ordered in large numbers by the Swedish air force to leap into the jet age. The Vampire family is known for its great dogfighting capabilities, meaning the J28B can comfortably fend off several opponents at once if controlled by a skillful pilot. This aerial performance is given at the cost of engine power.

== General info ==
=== Flight performance ===

The J28B performs well at low altitude where it easily outturns most opponents it faces. Thanks to the excellent flaps and air brakes, a pilot aware of his/her energy can fend off anyone that picks a fight. The flaps can be utilised at various speeds to outturn any enemy at any time. Dogfights are where the Vampire platform shines, it is a highly effective fighter with its relatively light airframe and smooth controls. Although the power is lacklustre, a pilot aware of his/her surroundings will have no difficulty avoiding incoming enemies. This lack of engine power will, however, cripple the J28B when it comes to acceleration. A Vampire tends to lose a lot of speed when engaged in turning. So gaining it back to defend itself against new opponents becomes a hassle. And even if a J28B pilot manages to get their speed up, catching a target will be close to impossible with a slow top speed. This lack of power hinders the J28B in many ways, mostly related to energy. This is why "Vamp" pilots are advised to climb at the beginning of a match, despite the lack of a decent climb rate.
[[File:Rocket J28B.png|thumb|The Aiming reticle of the Swedish m/51 rockets.]]
The J28B performs identically to the Vampire FB 5 which should not come as a surprise. The firepower is what makes them different, however. The J28B is outfitted with the Swedish Akan m/47B (short for "Automatkanon"), which is the Swedish designation of the British Hispano Mk.V, although the calibre and fire rate are the same, the burst mass is larger. This has to do with the Swedish ammunition. The Swedish ammo type contains more TNT and is fully tracer equipped, meaning stealth isn't an option. Despite this downside, the guns perform closer to the American AN/M3 guns instead of the British Hispanos, making the J28B the most effective Vampire in regards to firepower. The J28B is also outfitted with several types of anti-tank and anti-ship rockets. Despite lacking the large 1,000 lb bombs the FB 5 offers, the rockets offer a much different experience compared to the original model. The rockets fire one at a time held on by a Swedish rocket rack, pointing them further down than usual. The average pilot, especially the ones coming from the FB 5, will find this new placement tricky to get used to. But considering the single fire system, a skilled pilot might be able to rack up more destroyed tanks in ground battles compared to the FB 5. If this becomes too sufferable, however, it is recommended to use "Fire rocket salvo" instead to fire off two rockets at once, for a more traditional feel. It's not worth sacrificing accuracy for efficiency when it comes to rockets.

=== Survivability and armour ===


* 38 mm Bulletproof glass - Armoured windscreen
* 12.7 mm Steel - Armour plate behind the pilot's head
* 3 mm Steel - Armour plate under the engine

[[File:Armour values J28B.png|thumb|Armour found inside the J28B]]
The J28B has the same armour as the Vampire FB 5 as well as the Italian [[Vampire FB 52A]]. Despite being dangerous in a head-on due to the beefed-up guns, a J28B should never fully commit to a head-on engagement, the bulletproof glass will, however, save the pilot most of the time. The tail section is not easily saved though. The twin-boom makes it twice as likely to hit the traction of control surfaces. This leaves the J28B completely useless usually resulting in abandonment of the aircraft, which should be avoided at all costs.

== Armaments ==
=== Offensive armament ===

{{main|Akan m/47B (20 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 20 mm Akan m/47B cannons, chin-mounted (150 rpg = 600 total)

The 20mm m/47B cannons found inside the {{PAGENAME}} are fairly unique, as it's the only vehicle in the game carrying this specific version. The gun is identical to the British [[Hispano Mk.V (20 mm)|Hispano Mk.V]] found inside the British Vampire. Ammunition count and fire-rate are identical, but the weaponry differs in ammunition type. While the British guns use shells that lack tracing, along with less explosive, the Swedish HEF-T, and AP-T are the only two rounds available, resulting in every round being traced. This can seem overwhelming, but considering the amount of damage the {{PAGENAME}} deals in a single burst compared to the Hispano, the trade-off is worth it.

=== Suspended armament ===

{{main|m/49|m/49A|m/51}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 8 x m/49A rockets

The {{PAGENAME}} is incredibly feared in ground-battles due to the devastating m/49A rockets it carries. These rockets lack a high explosive-mass, especially compared to high-explosive rockets similar to it, such as the British [[RP-3]]. However, the Swedish rocket works more in a shape-charge matter, giving it high penetration values, and post-penetration damage. This means the {{PAGENAME}} is more likely to ammo-rack opponents than similar analogs, as the {{PAGENAME}} can engage opponents from any angle it wishes

* 8 x m/51 rockets

8 x m/51 rockets

Although visually indistinguishable from the m/49A, the m/51 rockets are very different in behavior from their older counterpart. These rockets are high-explosive, similar to how the British RP-3 behaves. The rocket lacks significant penetration, even when compared to the RP-3, making them quite redundant against tanks. They can be effectively used against lightly armoured vehicles, however, as the explosive spreads more towards the side rather than just forwardly. The rockets can also be used against aerial opponents, especially bombers. Since this rocket has a 10m/s faster travel-speed compared to the m/49A before it, they're slightly more useful when applied against aerial targets, even if they're less than ideal for this purpose.

4 x m/49 rockets

The final rocket modification found on the {{PAGENAME}} are the large 18cm m/49 hprak. Compared to the shaped charged m/49A, and the high-explosive m/51, these rockets are actually SAP (Semi-Armour Piercing), making them very unique for their type. Due to their size, the {{PAGENAME}} is only able to carry four. The rockets are fired differently from other types as-well, especially compared to conventional rockets that ignite before leaving the pylon. These rockets ignite like the American [[Tiny Tim]] rocket, in which the propellant is only ignited after leaving the pylon, giving it a bit of a delay before engaging. This makes them tricky to aim, and since they barely have 10% of the explosive found inside the American counterpart, they're very ineffective against tanks.

{{Notice|The {{PAGENAME}} features a rocket-rack pointing all suspended weapons ~5° downwards. This forces pilots to fly the plane horizontal to avoid missing the target but allows the {{PAGENAME}} to engage tanks without pointing its nose down a lot.}}

== Usage in battles ==
A J28B pilot should always be aware of his/her speed and altitude, or energy in more advanced terms. To avoid enemies with superior engine power using it as a boom and zoom target, a J28B pilot should use altitude to their advantage. Since the Vampire platform is bad at building up energy, the pilot should store as much energy as possible for when the battle begins. Before engaging targets, it can also be useful to always keep a speed of at least 400 km/h to limit the number of options an enemy has to counterattack. This also helps the J28B to swiftly turn around and begin a dogfight if the opponent commits to one. This playstyle can be applied to every Vampire plane in the game since they perform mostly the same. The J28B has to watch out for [[Ho 229 V3]] players, however, since they can outmatch the J28B in turning. A good way to counter the Horten is to make it bleed speed. Forcing it to turn once or twice and then extending away from the enemy.

A playstyle close to that of a propeller-driven aircraft can be applied, where energy is the key to survival. The J28B has quite the firepower compared to the other Vampire models. This can reward players who can safely head-on from a distance and then avoid incoming shots from the enemy. This will usually result in a critical hit or straight-up destruction if the enemy doesn't also avoid. The fired rounds are quite deadly and require less gun-time compared to the British counterpart. This gives the J28B an overall higher chance of surviving since it can afford to spend less time on each target. A pilot comfortable with their aim will easily outsmart opponents and make them think twice before engaging in a future dogfight with a {{PAGENAME}}.

== History ==

The Swedish air force carefully studied what was happening at the Fronts in WWII, and by 1944 it was already obvious that the propeller era was coming to a close. By early 1945, the Swedes had already begun a project to power the Saab J21 with a ramjet. However, it seemed this project would take far too long. By autumn of 1945, the J29 project was also beginning to take shape. But even this project wouldn't take to the skies until 1949, so a foreign design had to do until then.

The British de Havilland Vampire was one of the first jet-powered fighter planes to enter the market, and Sweden was very interested in this design. In early 1946, Sweden ordered 70 Vampire F Mk 1 models designated J28A, thus becoming one of the first customers of the Vampire. This version was mostly used as practice for the new era of jet-driven aircraft. But the Swedes became fond of the design. So when the export version of the Vampire FB 5 entered the market known as the Mk 50, Sweden was very interested and orders started in 1949. This version was to be known as the J28B or A28B depending on suspended armaments. This version differed from the Mk 1 by having a renewed, rounder tail section, and a lower placed elevator. The engine was upgraded from the RM1 to the RM1A that was now produced by SFA (Svenska flygmotor AB) in Sweden and delivered to de Havilland in Britain for installation. The main armament was also changed from the Hispano Mk II to the more potent Hispano Mk V. By 1952, 310 J28B Vampires had been delivered to Sweden. 12 of these would be rebuilt as a two-seat trainer, known as the J28C-3.

A pilot comfortable with their aim will easily outsmart opponents and make them think twice before engaging in a future dogfight with a {{PAGENAME}}.

== History ==

The Swedish air force carefully studied what was happening at the Fronts in WWII, and by 1944 it was already obvious that the propeller era was coming to a close. By early 1945, the Swedes had already begun a project to power the Saab J21 with a ramjet. However, it seemed this project would take far too long. By autumn of 1945, the J29 project was also beginning to take shape. But even this project wouldn't take to the skies until 1949, so a foreign design had to do until then.

The British de Havilland Vampire was one of the first jet-powered fighter planes to enter the market, and Sweden was very interested in this design. In early 1946, Sweden ordered 70 Vampire F Mk 1 models designated J28A, thus becoming one of the first customers of the Vampire. This version was mostly used as practice for the new era of jet-driven aircraft. But the Swedes became fond of the design. So when the export version of the Vampire FB 5 entered the market known as the Mk 50, Sweden was very interested and orders started in 1949. This version was to be known as the J28B or A28B depending on suspended armaments. This version differed from the Mk 1 by having a renewed, rounder tail section, and a lower placed elevator. The engine was upgraded from the RM1 to the RM1A that was now produced by SFA (Svenska flygmotor AB) in Sweden and delivered to de Havilland in Britain for installation. The main armament was also changed from the Hispano Mk II to the more potent Hispano Mk V. By 1952, 310 J28B Vampires had been delivered to Sweden. 12 of these would be rebuilt as a two-seat trainer, known as the J28C-3.

=== Survivability and armour ===
''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.''

== Armaments ==
=== Main armament ===

{{main|Rbs 55}}

The Rbs 55 is the same ATGM launcher found on the [[UDES 33]] but gets access to better munitions. The reload time is the same as the UDES so enemies will be able to replace their crew member quicker than your reload. It also gets less ammo, carrying only 8 rounds instead of 10. It is recommended to take a full ammo load as you will definitely run low during an extended battle. The firing angles are more restricted vertically, with only -13° compared to the UDES' -20°. It is horizontally restricted to the 4 o'clock right and 8 o'clock left positions.

However, there is one big upgrade this launcher gets compared to the UDES; the ammunition. It starts off with the potent RB 55B (I-TOW) but can upgrade to the deadly RB 55C (TOW-2). The RB 55B is a good stock munition, being able to penetrate most, if not all, vehicles it faces within its BR range. However, the RB 55C is one of the best ATGMs at its BR range. With 800 mm of penetration, it has the ability to penetrate all vehicles at its BR and more. The slightly higher velocity makes it easier to hit long range targets before they can potentially drive into cover. It's also a Tier II modification so it can be unlocked relatively fast. This makes the launcher one of the most dangerous weapons to face at any range, provided the operator can stay alive, as the gunner is exposed from the waist up on the vehicle.

== Usage in battles ==
''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

== History ==


In 1983, the Swedish military gave a contract to Hägglunds and Söner to convert Ikv 102 and Ikv 103 vehicles into Pvrbv 551 anti-tank missile carriers. The Ikv 102 and Ikv 103, infantry support vehicles mounting a 105 mm gun, had become obsolete in the past few years. At the same time, the same companies were contracted to convert Ikv 102 and Ikv 103 vehicles into Lvrbv 701 surface-to-air missile carriers. The hull of the Ikv 102/Ikv 103 was plated over, in order to extend the crew compartment the full length of the vehicle. The engine was replaced by a Ford V-6 engine. The armament consisted of a TOW ATGM launcher in the center of the hull, which was raised up through a circular opening in the roof of the vehicle - covered by a two piece hatch - in order to fire the weapon. 55 Pvrbv 551 vehicles were delivered to the Swedish military.
