[[File:War Thunder Screenshot 2021.09.12 - 09.54.41.07.png|thumb]]
The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].

The {{PAGENAME}} was a private venture by Bofors to design a next generation assault gun for both export purposes and indigenous use following WWII. The main goal was to make a light and manoeuvrable armoured vehicle with a 12 cm autocannon, capable of dealing with both soft targets and enemy tanks. A prototype was built during the late 1940s but no one was willing to buy it in a world that was littered in cheap surplus military vehicles and the project was scrapped.

In-game it is a very fast vehicle with a low silhouette and can easily manoeuvre around the map and flank enemies. It is armed with the aforementioned 12 cm autocannon of Bofors design and has a fire rate of 50 rounds per minute, meaning a reload speed of 1.2 seconds between shots, which is the highest in the game for its calibre. The gun's velocity however is subpar and requires good aim and close quarters combat to be effective. Another result of the low velocity is subpar penetration, but because of the vehicle's high mobility, coupled with the gun's high fire rate and powerful ammunition, it has no trouble taking on any type of vehicle that it may come across during conventional matches.

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


The SAV 20.12.48 is very lightly armoured, sacrificing protection for mobility. The highly sloped glacis is 30 mm thick, and can sometimes cause rounds to ricochet, but it is not reliable in any sense of the word. The rest of the tank is vulnerable to even heavy machine guns, and the open top is extremely vulnerable to strafing aircraft. Ammunition is stored in two primary deposits at the back of the crew compartment and is easily hit if the vehicle is penetrated.

The SAV 20.12.48 has excellent mobility for a tank destroyer, featuring a high top speed as well as a fast reverse. The result is a highly agile tank destroyer that is capable of taking positions or retreating into cover quickly.

=== Main armament ===
{{Specs-Tank-Weapon|1}}

{{main|automatkanon (120 mm)}}

The '''120 mm automatkanon''' is a potentially devastating weapon. It is fitted with an automatic loader that is fed by a six-round clip, for a total of seven shots ready to go once fully loaded (including one in the gun barrel). The autoloader has an extremely fast reload of only 1.2 s, allowing the Sav 20.12.48 to engage up to seven targets in under 10 s. Once the clip has been expended, a new round must be loaded into the clip before the autoloader may be cycled and the gun made ready to fire. However, this process only takes a few seconds. The gun also has a good amount of gun depression, allowing the Sav 20.12.48 to abuse hills when combined with the high reverse speed.

The primary shell is the '''hpgr m/50''' APCBC round. With nearly 1 kg of explosive filler, it is extremely deadly and almost guaranteed to one-shot anything if it penetrates the crew compartment. Its penetration is quite respectable; although not quite enough to frontally penetrate everything the Sav 20.12.48 can encounter, it has more than enough penetration to kill most tanks from the side. It has a relatively low muzzle velocity, however, and is thus hard to hit with at long range.

The combination of high mobility, powerful explosive filler APCBC shells, and autoloader make the Sav 20.12.48 an extremely dangerous tank destroyer to face. It is fast enough to quickly setup ambush positions near where the enemy team is likely to pass by, and a careless team can quickly find itself losing up to seven tanks in less than 10 s to the Sav 20.12.48 lying in ambush. Ideally, the Sav 20.12.48 would also be in a hull down position, where most of the tank can be hidden since the gun is mounted near the top of the vehicle and the high reverse speed allows it to back into cover quickly.

The vehicle itself is very fragile, however, and if it is caught out of position it is very easily destroyed. It is also very vulnerable to aircraft due to the open top, and has no means of defending itself from aircraft.

It can also be very tempting to fire off all seven rounds at once, but as with all autoloaders, trigger discipline is a very important skill to develop in order to use the vehicle to its full potential.

Most of the heavy tanks that the SAV 20.12.48 is able to face are largely resistant to your shells, especially if they're angled. If you see a KV-1 or Churchill, disengage and let your allies with better firepower take these out.

=== Pros and cons ===


'''Pros:'''

* Highly lethal APCBC explosive filler shells
* Good mobility and high reverse speed
* Can fire seven rounds within 9 s using the autoloader
* Excellent gun depression
* Small silhouette, especially when hull down
* High hp/ton ratio - not many enemy or allied vehicles are as quick to accelerate or able to reach high speeds as quickly
* Penetration usually is a one-shot due to the high amount of explosive filler in the APCBC shells
* Extremely effective in an ambush role - an SAV 20.12.48 left unchecked can destroy an entire flank in rapid succession

'''Cons:'''

* Very thin armour
* Open crew compartment, highly vulnerable to strafing aircraft
* Must reload at least one round into clip before the gun can be fired
* Low shell velocity
* Sustained firing decreases accuracy
* Struggles to penetrate heavy tanks like the KV-1 and Churchill series of tanks, even at close range or from the sides
* Magazine can quickly be depleted - replenishing the entire magazine takes up a lot of time
* Only 3 crew members - low survivability

=== [[wt:en/news/6510-development-sav-20-12-48-nordic-sledgehammer-en|Devblog]] ===
In 1948, Bofors began work on developing a new self-propelled gun as part of a private venture in an effort to realize a long-lasting goal of establishing itself as a manufacturer of armored fighting vehicles, alongside its already proven reputation in arms production.

To do so, Bofors came up with a design for a new SPG, which incorporated a 12cm cannon, whose design was heavily inspired by those used on destroyer vessels, along with a highly effective autoloading mechanism. The design was ready by the end of 1948 and a single prototype was constructed in the following year.

However, while test results didn't seem to impress the Swedish military enough to consider placing an order for the vehicle, the factor that certainly sealed the vehicle's fate for good was its price. Namely, being developed with the use of its own funding, Bofors had to demand a high production price for the vehicle, a price deemed too high by the Swedish military considering the vehicle's most probable role being an infantry support vehicle.

As a result of the lacking interest, the SAV 20.12.48 never went into production. Despite its failure, the project wasn't a complete loss for Bofors, as some of the experiences gained during its development later found application in other vehicles, such as the far more successful Strv 103.

== 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 1.95 "Northern Wind"]].

The J29F is the final variant of the J29 "Tunnan" family, combining excellent engine performance, and maneuverability 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 ===


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 ===


[[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.

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

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

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

* 4 x 20 mm Akan m/47C autocannons (180 RPG - 720 rounds 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 ===

{{main|m/55|Rb24}}

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

* Without load
* 24 x m/55 unguided rockets
* 2 x Rb24 air-to-air 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.

== 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 test pilot chosen for this flight was an Englishman by the name of Squadron Leader Robert A. "Bob" Moore. 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 ===
The J29F was an upgraded 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.

== 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.

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.

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.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.93 "Shark Attack"]].

When conjuring up thoughts of fighter jets, many would initially think of a sleek, weapon-laden fast jet which would almost rival a hot-rod in the car world. When presented with the {{PAGENAME}}, most people would cock their head to the side with a puzzled look on their face. It's a good thing that fighter jets are not determined by looks alone! The {{PAGENAME}} is, for lack of a better phrase, a "wolf in sheep's clothing", initially laughed at as being the "chubby kid on the block". Once up in the air, however, it is quickly realised that this rotund little fighter is a dynamic powerhouse!
[[File:J29D_004.png|350px|thumb|left|'''{{PAGENAME}}''' in a power climb launching a [[m/49]] unguided rocket.]]
While many other nations were fixated on designing straight-wing aircraft, the Swedes were busy exploiting the knowledge of former Messerschmitt engineers in implementing swept wings onto their fighters. With this and other improvements, the {{PAGENAME}} was an attempt by the Swedish air force at creating a fast climbing bomber-interceptor armed with the deadliest fixed armament for its time. Although it was not supersonic, it could reach speeds above 1060 km/h at certain altitudes. The nose of the aircraft was bristling with four 30 mm autocannons and several types of attack rockets could be mounted beneath its wings. A lesson from WWII was that the best aircraft were the ones capable of performing several roles, and the {{PAGENAME}} is indeed capable of performing more than one role. Depending on the load-out, the {{PAGENAME}} can perform anything from interceptor missions to air superiority missions to high speed attack missions. This functionality makes the J29D extremely versatile and a valuable asset to its team in the game.

If not kept in check, the {{PAGENAME}} can quickly become the bully on the block hard-charging into the battlefield, wreaking havoc and then departing without a second thought. If two fighters are headed your way, your best bet will be to take out the {{PAGENAME}} first or it will likely nab you in the rear and send you down in flames.

=== Flight performance ===

[[File:J29D_001.png|450px|thumb|right|'''{{PAGENAME}}''' removing one wing at a time on a Me 262.]]
When flying the {{PAGENAME}}, it is hoped that enemy pilots will take one look, chuckle, and not take the rotund Swedish fighter seriously, only to learn the hard way they were wrong. The {{PAGENAME}} has the speed, agility, and ordnance to be considered a powerhouse in the sky. Being outfitted with an afterburning engine, the {{PAGENAME}} can fly upwards of 1,000 km/h and climbs up to altitude at a whipping 55 metres per second. This allows the fighter to get in and out of contested areas to engage its targets of choice. This fighter was built for speed and agility and uses these characteristics to show up other aircraft which may be faster or bulkier, sidestepping their attacks and jumping back in to nab the kill. Thanks to the way the four ADEN cannons are mounted when the {{PAGENAME}} lines up a target and fires, it is almost like a 30 mm shotgun being fired off. A tight spread of 30 mm rounds heads downfield, and when impacting another aircraft, rarely is there enough left of the plane to fly.

The {{PAGENAME}} is as comfortable up at altitude as it is down at just above ground level. The fighter is a stable platform when it comes to ground attack, with good acceleration characteristics when the time comes to peel off the ground targets and manoeuvre back up to altitude with the other fighters. Being specially designed to reduce as much drag as possible, the swept-back wings help extend the breakage limits of the wings, especially when this fighter is in a dive.

=== Survivability and armour ===


;Armour

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

The stout little {{PAGENAME}} 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 {{PAGENAME}} have a hard time standing up to this aircraft.

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

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

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

* 4 x 30 mm Akan m/55 cannons, nose-mounted (100 rpg = 400 total)

The {{PAGENAME}}, like many of the fighters of the time, got away from machine guns and was outfitted with harder-hitting autocannons, in this case, 30 mm ADEN cannons. The cannons are clustered around the central air-intake of the aircraft, resulting in optimal fire control as convergence is not an issue. However, the pilot must still correct for bullet drop for the 30 mm rounds. The four ADEN cannons only have 100 rounds per gun, requiring the pilot to exercise trigger control so not to waste ammunition. With these harder hitting rounds, however, only a quick burst is needed to send an aircraft down in a flaming heap.[[File:J29D_006.jpg|400px|thumb|right|'''{{PAGENAME}}''' firing off a [[m/49]] unguided rocket.]]

=== Suspended armament ===

{{main|m/49|m/49A|m/51|m/55}}

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

* Without load

== Usage in battles ==


Although the J29D is a fast jet capable of reaching high speed, at the start it can be pretty slow. The J29D has the chance to fight supersonic jets at its battle rating which it can't hunt down by itself. As such, the J29D is best used in teamwork with other jets to either catch up to the enemy plane or make them do manoeuvres to bleed some speed so the J29D can catch up. If faced with subsonic jets, it can keep up with them and stay on its tail thanks to its manoeuvrability. For the daredevils, the J29D has an excellent armament of choice to do head-ons with. These load outs would be best put to use if no teammate around to help you fight the enemy. Because the J29D has slow acceleration at the start of the game, it can have a hard time intercepting enemies at first. As the battle progresses and you will have worked up speed, this task will be made much easier.

The J29D can also be used as an excellent ground attacker for more experienced players who are used to aiming unguided rockets. It has a variety of rockets, allowing you to sufficiently take out a wide variety of targets (light, medium, heavy, etc.). With most loads having more than 10 rockets, an experienced player can take out a few ground targets each spawn. Along with the rockets, the four 30 mm guns, given the proper belt choice, can inflict heavy damage upon soft and somewhat hard targets as well.

Even as an excellent fighter, the J92D has dangerous enemies, mainly high-subsonic jets like MiG-17 and anti-air missile firing jets like G.91 YS and Swift F.7.

[[File:J29D_002.jpg|450px|thumb|right|'''{{PAGENAME}}''' cruising the sky looking for targets.]]
=== 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 test pilot chosen for this flight was an Englishman by the name of Squadron Leader Robert A. "Bob" Moore. 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.

=== J29D ===
Even before production of the [[J29A]] had started in the late 1940s, the Swedish Air Force started to discuss the use of an afterburner in the J29. While the J29 was very advanced for its time, it became clear pretty early on that it did not have the climb rate needed to effectively intercept high altitude strategic bombers. To solve this it was decided to start projecting an indigenous afterburner for the J29. Flygmotor, who was license-producing the de Havilland Ghost engine was tasked to develop an afterburning version of it. After initial calculations it was concluded that the new afterburner would increase power by ~25% and double the climb rate.

Besides introducing an afterburner there was also a lot of talk about increasing the armament of the J29. Several ideas were brought up, everything from anti-air missiles to anti-air rockets to more powerful guns. In the end it was decided that all 3 ideas would be tested. Since there were a few 30 mm aircraft guns on the international market by the start of the 1950s, it was decided to trial the new J29 with new guns first. Thus, in April 1952, a [[J29A]] from air wing F 13 was sent to the Swedish Air Force experimental bureau Försökscentralen (FC) to be fitted with mockups of 30 mm guns for flight testing. Flight testing with mockups was performed as the barrels of the new 30 mm guns were protruding out from the front of the J29 which could interfere with flight characteristics. After 4 months of successful flight trials completed, the aircraft was restored and sent back to air wing F 13.

About 2 years later, the afterburning Ghost engine was finished and it was decided to install it in the [[J/A29B|J29B]] prototype, then becoming the J29D prototype. The J29D prototype flew for the first time on the 20th of March, 1954. Initial flight trials were apparently successful, however during trestle-mount ground trials in 1954 it was found that the 30 mm guns selected for the J29D were flawed and the idea to use these was scrapped. Instead it was decided that anti-air rockets and missiles were the way to go. SAAB at this time had also projected a new wing for the J29, a so-called dog-tooth wing which improved airflow and handling. It was decided that all future J29s would feature this dog-tooth wing and thus the J29D project was scrapped. Instead, it was decided to make an afterburning J29 with the new dog-tooth wings. Unfortunately as production of the afterburning Ghost engine was not ready yet it was decided to introduce the new dog-tooth wing first in an intermediate version called the J29E, which consisted of J29Bs being modified in the factory or in the field with the new wings. The plan was to later retrofit 210 of the J29B and J29E models with dog-tooth wings and afterburning Ghost engines, turning them into J29Fs.

Luckily this was not the end for the J29D prototype, in order to test the J29F concept it was decided to modify the J29D prototype into the J29F prototype. Modifications were done by early February 1955 and the J29F prototype was approved for service in April the same year. The same year, Bofors would finalize the projected anti-air rockets which entered service on the J29B, E and F as the 75 mm [[Srak m/55 Frida|srak m/55]]. In 1956, the legacy of the J29D would end, as the J29F entered service.

While Sweden traditionally imported a great deal of military tech, including in its aircraft, Swedish aeronautical engineers nevertheless developed and built combat aircraft of their own design. Like the leading world powers, in the immediate post-war years Sweden focused its research capabilities on jet-powered aircraft. Even before the outbreak of World War II, research into jet engines was already taking place in Sweden, and the war gave industry experts the opportunity to acquire priceless experience studying the progress made by other countries, Germany in particular.

At the beginning of 1945, a project to build the first jet-powered fighter was born deep in SAAB headquarters. Immediately after the end of the war, Swedes bought the license to produce turbojet engines from the British company de Havilland, and they began converting their J-21 piston-engine fighters to jet-engine fighters. With the arrival of the new Ghost engine from the Brits and promising research into swept wings, SAAB began developing a fundamentally new kind of fighter, initially planned to be fitted with a jet engine. Within a short time, the Swedish Air Force received the J29 Tunnan. Named after the Swedish word for "barrel", based on its shape.

The Tunnan was an awkward-looking machine, but one with superb flight characteristics for the time, enabled by its swept wings. Judge for yourselves: successful testing took place in 1948, followed by mass production in 1951, and by 1954 the J29B modification set the world speed record in a closed circuit. That's impressive!

== 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 1.95 "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.

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

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 ===
''Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.''

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

{{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 ==

In RB and Sim modes, this plane 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.

Turning is generally a bad idea, the "Flying Barrel" loves to lose speed and hates to recover it so keep this in mind before pulling any sharp manoeuvres.

To engage in a primary dogfight you will either want to be well above it or at high speed to take advantage of the greatest strengths of this plane: its cannons and top speed.

Speed is life, but sometimes you won't have enough of it, keeping an eye on where your nearest teammate is is an excellent idea should you need support when engaged by a faster jet ([[Swift F.1]]/[[Swift F.7|F.7]] are common examples).

Flying with a squadmate in a more dogfight-suitable aircraft is highly recommended to make the most out of this plane, as they will often be able to setup a target for your B&Z runs.

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.

=== Survivability and armor ===
''Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armored, etc. Describe the armor, if there is any, and also mention the vulnerability of other critical aircraft systems.''

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

{{main|Browning M2 (12.7 mm)|Browning (7.62 mm)}}

* 2 x 12.7 mm (0.5 in) Browning AN/M2 machine guns (470 rounds)
* 4 x 7.62 mm (0.3 in) Browning machine guns (1960 rounds)

=== Suspended armament ===

{{main|AN-M64A1 (500 lb)}}

* 1 x AN-M64A1 500 lb bomb

== Usage in the battles ==

The most plausible manner to use this aircraft is in the Boom & Zoom role, given its fast speed in a dive. In addition, the nose-mounted .50 caliber can help you preform certain attacks a P-40E pilot could dream of doing. However, there are certain methods to using the plane, as it is an earlier iteration of the H-81A-2 is a P-40.

The first method is to climb to altitude, and try to intercept enemy attackers and bombers. This tends to play in favor of the H-81A-2, due to its excellent top speed of 528 kph (328 mph) at 3,800 meters (12,467 feet.) That being said though, you are inhibited by its relatively slow rate of climb of only 10 meters/second (32 feet/second.) On the contrary, once you reach altitude, Boom & Zoom as much as you want against bombers, as your high dive speed will make it difficult for most gunners to target you. In addition, you have a nice turn speed of 21 seconds, which can allow you to snap over on some opponents with relative impunity. If you do find yourself fighting in the vertical, flaps will also be of use to you, as they do have a decent speed tolerance before they snap off.

====Specific enemies worth noting====

Perhaps the biggest threat comes from facing any Japanese plane at this battle rating. They can turn so much faster than you as to bleed your speed and energy to the point of stalling out. The greatest threats come from the Ki-44s and the A6M2-N. In addition, the Ki-43 has significantly greater maneuverability than you. The vast majority of these planes have guns similar in caliber to a .50 Cal, which means that they have the firepower to dispatch you at a fairly fast rate.

In terms of the British, any Spitfire or Hurricane will out-turn you. While they do not have as heavy of armament as you do, the shear rate of fire from the .308s can light up exposed ares of the plane, or even score a pilot kill. While it is mostly unlikely, the Spitfire Mk. IIb not only boasts maneuverability, but also two 20 mm Hispano cannons, which can tear you to bits. In addition, almost all British fighters can out-climb you, which leaves you at a disadvantage in energy.

The Germans have the most planes that can give you a problem, due to the vast majority of them having 20 mm cannons. Most notably are aircraft like the Bf-110 and the Bf-109 E-3. You also do have to worry about aircraft like the Bf-109 F-1, which has a 20 mm cannon in the propeller hub. While it is unlikely, you may also face the Fw-190 A-1. Most German planes will have a significantly better climb rate than you and be able to energy fight you more efficiently. As mentioned earlier, most German planes boast much heavier firepower than you, which renders you at a disadvantage in punching power.

Most Russian planes will also give you a run for your money. Almost all of the Russian planes boast only nose-mounted weaponry, giving them a significant advantage over most allied planes. The most common enemies to worry about are any plane with the prefix "Yak." Perhaps the most common cause of US teams being defeated by the Russians, is the fact that they head on an IL-2. '''Never''' under any circumstance head on an IL-2.

====Counter-tactics====

As mentioned earlier, the H-81A-2 has nose-mounted .50 cals, which can make short work of almost any fighter at battle rating 2.3. The aircraft also has a tighter turning time than the P-40E, which can give a H-81A-2 pilot a small advantage. If a H-81A-2 finds its way onto your tail, try to make the pilot over-shoot or bleed energy. The cockpit, while having more protection than an open top and a bubble canopy, is still a fairly vulnerable spot, so pilot snipes aren't uncommon.

Heads up for German and Russian pilots! While aircraft like the Bf-110, LaGG-3 and the Yaks have nose-mounted weaponry, an experienced H-81A-2 player can still make you pay dearly in a head-on. If you find yourself in a head on with a H-81A-2, fire a short burst, then hit the deck to avoid being hit by return fire. This is especially true with the Russians due to their wooden air frame.

== History ==
The H-81A-2 is one of the export versions given to the ROC though the American Volunteer Groups sent to China. The volunteer force was sent by US president Franklin Roosevelt to deter Japanese aggression during the Second Sino-Japanese War. At the time these aircraft were a relief for the Chinese aid as the aircraft they were using at the time, primarily I-16s and I-15s, did not compete well against the Japanese air force. The only unit of these volunteer groups to actually see combat against the Japanese forces was the 1st AVG, otherwise known as the "Flying Tigers".
