== Description ==

The last aircraft ever produced by the famous Supermarine company, the Scimitar was developed to meet the Royal Navy's requirements for an aircraft with good low-altitude manoeuvrability and wide choice of strike ordnance. Featuring two large Rolls Royce Avon Mk.202 engines, the Scimitar was the heaviest and most powerful aircraft to have been in service with the Fleet Air Arm at its entry in 1958. While the plane was generally praised for its low-level and low-speed flight characteristics, helped in part by a special flap-blowing system that allowed some of the excess thrust to be redirected across the flaps to reduce its stall speed, over half of the 76 Scimitars produced were lost to accidents, and the plane had generally poor reliability and serviceability. The aircraft was quickly relegated to second line duties with the introduction of the [[Buccaneer S.1|Blackburn Buccaneer]] in 1962, and was finally retired completely in 1970.

Introduced in [[Update "Starfighters"]], the Scimitar is a heavy but very powerful carrier-borne fighter. Its two immensely powerful engines make it one of the fastest subsonic aircraft in the game and afford it great acceleration and climb rate, however its interesting handling characteristics can make it an particular challenge to fly. Notably, while the pitch and roll capabilities are generally sufficient, especially for such a large aircraft, the poor rudder response at high speed can make the four powerful ADEN cannons (difficult to handle at the best of times) extremely impractical to aim. However, this limitation can be mitigated by sensible approach planning, and by making proper use of the four AIM-9B Sidewinder missiles also able to be equipped. As well as being a powerful fighter, the Scimitar has excellent ground attack capability, and is the first British aircraft (second being the Buccaneer) capable of carrying air-to-ground missiles.

{{Specs-Avia-Flight}}

[[File:Rudder Demonstration .png|thumb|''Full left yaw at 1,000 km/h'']]
The Scimitar F.1 is a relatively large and heavy aircraft, but it is still extremely capable because of its impressive engines. The Scimitar's two Rolls-Royce Avon 202 engines put out 4,650 kgf of thrust each, giving the Scimitar its fantastic climb rate of over 100 m/s. This outclasses similarly placed jets known for their climb rate (such as the [[MiG-15]]) by almost 2 times, and it's capable of gaining speed in a 45° climb. The impressive amount of power means that, assuming you aren't uptiered to 9.7, you will always be the first off the airfield and into combat. The Scimitar has a max speed of just over 1,160 km/h or mach 0.95 on the deck, enough to outrun anything at its BR, and even some missiles too. In an uptier, there are many planes faster than you so be extra cautious: don't engage first and look for an opportunity.

The Scimitar has very poor manoeuvrability due to its large weight and size, the yaw controls are particularly bad. It is therefore recommended that you only engage low energy targets and use the element of surprise so they cannot evade. If the target is aware of your presence, they will easily evade you. Unlike other jets at its BR, the Scimitar also struggles to dodge missiles. You should make sure that no one is in a position to be on your six since once an enemy is behind you and gaining on you, there is nothing you can do. The Scimitar does get 4 x AIM-9B missiles, and these can be used on targets that use your lack of a rudder against you, however you should keep in mind that they are only 10G missiles and can easily be dodged by the enemy. Overall this aircraft seems good on paper, however its poor handling plays hugely against it.

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

The Scimitar has one glass 50 mm plate in front of the pilot, and one 12.7 mm steel plate behind the pilot. It has very low survivability because any wing damage will lead to a flatspin, due to its lack of rudder control.

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

The poor rudder of the Scimitar makes getting two modifications a high priority. The New boosters modification provides a noticeable improvement to the rudder control of the Scimitar and is your absolute top priority, as any rudder improvement you can get will make getting guns on target, and flying the aircraft in general, more bearable. Even with the New boosters modification getting guns on target can still be rather hard; therefore the next priority is AIM-9B missiles as they give you another way to kill enemy aircraft, which is less reliant on rudder control. Even stock the Scimitar exhibits very impressive flight performance for its battle rating, this means flight performance upgrades (with the exception of New boosters) are not as important as on other jets. Starting at tier 1, you will want to unlock the rockets (to start progressing towards AIM-9Bs), then at tier 2 unlock the New boosters modification and then the bombs. At tier three do your choice of flight performance modification followed by the Bullpups (unless you want the Bullpups for Tank RB, in which case get them first); finally get the AIM-9Bs at tier 4. From here on you can unlock the remaining modifications according to user preference.

If you find unlocking modifications difficult due to the lack of rudder control then the stock ADEN belts are capable of killing light pillboxes/light tanks (and medium tanks with some more difficulty), allowing you to get a decent amount of RP per game through ground attack. The suspended armaments can also be used for ground attack or base bombing.

== Usage in battles ==


Thanks to its very powerful engines (it has a higher total thrust output than many supersonic aircraft), the Scimitar possesses an exception rate of climb and top speed for its BR, being easily one of, if not the fastest subsonic aircraft in the game. You should use this to your advantage when playing the Scimitar. At the start of the game you can choose to either go high or go low.

If you choose to go high then you should use your rate of climb to get above the enemy and either pick off bombers (your missiles can help greatly with this) or position yourself ready to dive down on enemy players, many of whom will still be climbing. Going low is the riskier option and relies on the Scimitar's immense speed for your survival. You should stick below 2,000 m altitude and work your way towards the edge of the battle, then turn into the fight and choose targets to attack, making a single pass before using your speed to escape. You should keep your speed up at all times and regularly check your tail for aircraft and missiles. While you can easily out run just about all subsonic aircraft, supersonic aircraft can cause you problems. Likewise you can outrun missiles launched at longer ranges, but not those launched close to you.

Whichever playstyle you choose, the Scimitar will offer you a powerful armament of 4 ADEN cannons, with a plentiful supply of ammunition. You also have access to 4 [[AIM-9B]] missiles. While the AIM-9B is nothing special compared to other missiles (being about average for this BR range) it can be very useful once you learn how to use them. In particular, they make taking out bombers much easier. The Scimitar is also a very capable CAS platform with powerful cannons (can kill light pillboxes and medium tanks in Air RB, and penetrate the tops of some tanks in ground RB), and an assortment of ground attack load-outs. Notably it is the first British aircraft to get access to air-to-ground missiles, in the form of the [[AGM-12B Bullpup]].

Despite these advantages the Scimitar does have some major drawbacks, mainly related to manoeuvrability. While it can turn better than you would expect for an aircraft of its weight, it is by no means a nimble aircraft and should not be treated like one; prolonged turning engagements should be a last resort. The key drawback of the Scimitar is its poor rudder response at high speed, this can make getting guns on target difficult, and leaves you relying more on your decidedly average [[AIM-9B]] missiles for kills. The Scimitar also does not pull negative Gs particularly well at high speed.

===Radars===

The Scimitar F Mk.1 is equipped with an AN/APG-30 rangefinding radar, located in the nose of the aircraft.
It will automatically detect other planes within the scanning area and display the range to the closest target. It is linked with a gyro gunsight and can help with aiming at close range.

=== Pros and cons ===


'''Pros:'''

* Possibly the fastest subsonic jet currently in the game at its battle rating, reaching 1,161 km/h (Mach 0.95) in level flight at sea level
* Has very good acceleration
* Has four ADEN cannons, which are some of the best guns in the game
* Lots of cannon ammo
* Has good ground attack capability thanks to its air-to-ground missiles
* Can utilise four air-to-air missiles ([[AIM-9B]])
* It is extremely difficult to break the wings by pulling positive Gs, generally wing breakage in the Scimitar only occurs when pulling negative Gs
* Capable of landing on carriers

'''Cons:'''

* Cannot make good use of its speed in turns as the rudder severely locks up at even moderately high speeds
* Combination of poor rudder control and gun placement can make getting guns on target extremely hard
* Does not turn very well
* Asymmetric wing damage is liable to cause a non-recoverable flat spin
* Elevator is single piece. Taking damage through is fatal

== History ==

'''Development and Operation'''

The Supermarine Scimitar was a naval strike aircraft with a limited production run for the Royal Navy's Fleet Air Arm. The Navy's specifications required the aircraft to be effective in a strike-fighter/attacker role which consisted of proficient manoeuvrability at low altitudes and plenty of ordnance options for ground attack operations. Issues with the desired handling became apparent quickly as it was the heaviest aircraft to see service for the Fleet Air Arm; weighing 34,200 lb even before being equipped with four 1,000 lb bombs or AGM-34 bullpup missile configurations. Nuclear capability was also planned for the aircraft through the use of a Red Beard nuclear bomb was uncertain and never fully realised.<ref name=":0">https://www.tangmere-museum.org.uk/aircraft-month/supermarine-scimitar</ref>

With aircraft carriers modernising, and the Royal Navy requiring an upgraded capability to strike at sea, the experimental aircraft took its maiden flight on the 31st of August 1951. The first prototype emerged, powered by significant thrust generating Rolls Royce Avon jet engines. 11,250 lb of thrust combined with flaps and a system to redirect the thrust downward with the use of small vent ports just in front of the flaps, pushed the stall speed back allowing for theoretically safer carrier landings and generally more dextrous low-speed manoeuvres. This was a necessary innovation as most British carrier decks were short and snug due to the budget constraints. Scimitars remained on land at RAF bases whilst undergoing thorough testing for their safety and competency. The potency of the thrust from the Avon engines was proved when a pilot successfully managed to perform a take-off with the parking brake on. The third prototype design was the first to feature swept wings which would remain for the rest of the aircraft's short life.

By January 1957, testing began on the Royal Navy's flagship, HMS Ark Royal; and around the same time, the first operational model would leave production. The aircraft already plagued with several incidents in testing would see 803 Naval Air Squadron's wing commander lose his life in the Persian Sea after a brake failure caused the aircraft to fall overboard during a landing. Further adjustments were made to the delicate aircraft such as the method of launching it at an upward angle with the use of a 'bumper' on the back. It would hold the aircraft in place as it was hoisted skyward until the nose gear was suspended off the ground. This position allowed the noticeably weak catapults to launch the heavyweight of the aircraft.<ref name=":1">https://www.thunder-and-lightnings.co.uk/scimitar/history.php</ref>

The Scimitar never saw any combat though served operationally with the Royal Navy in the Persian Gulf to deter tensions developing from Iraq at the time. Some sorties were undertaken to test the capability of the aircraft's missile and rocket payloads, but live bombs were never sortied because of fears the risks were too great, and the training was too dangerous; therefore practice bombs were often used instead.<ref name=":1" />

'''Fate'''

The 100 orders for Supermarine Scimitars would ultimately never be fulfilled. Only 76 units were delivered, of which 39 were lost to non-combat accidents; therefore 51% of all Scimitars produced were lost. Moving forward the carrier-borne strike fighting role was undertaken by the de Havilland Sea Vampire. The Supermarine Scimitar would ultimately become a prize piece of engineering, spending the last of its years stunning in air show performances where it did succeed. The Scimitar had a short and constantly troubled history which looked doomed to failure from the beginning; the Royal Navy was subsequently deemed unable to operate such an intensive aircraft which required enormous cost, time, expertise and top-spec equipment to allow its success in operations, none of which the Royal Navy had enough of at the time. On 19 October 1966, the Scimitar was retired from the Naval Air Squadron and in December of 1970 the last Scimitars flew, with pilots still avowing that the aircraft was 'a delight to fly'.<ref name=":0" /><ref name=":1" />

=== [[wt:en/news/6730-development-scimitar-f-1-the-twin-engine-beast-en|Devblog]] ===
Development of what would eventually turn out to be the Supermarine Scimitar began as early as the late 1940's, with the Supermarine company starting work on developing an undercarriage-less naval jet fighter, following a specification issued previously by the Admiralty.

During development, several prototypes were built and tested while at the same time the design of the machine continued to change and evolve. Eventually, however, the undercarriage-less concept was dropped and the machine was even reclassified to a low altitude strike aircraft, with the Royal Navy ordering 100 units of the latest prototype design - the Type 544 - into production in 1954. The Type 544 prototype first flew in January 1956, while the first production version of the Scimitar ran off the assembly line a year later in 1957.

The Scimitar entered service with the Fleet Air Arm in 1957. However, the carriers of the Royal Navy at the time were rather small while the Scimitar was a relatively large aircraft resulting in high accident rates which would plague the Scimitar's service career. Furthermore, the Scimitar was a highly demanding aircraft from a maintenance standpoint, making it even less popular with its crews.

As a result, the Supermarine Scimitar only had a relatively short service career with the FAA, which withdrew the Scimitar from active service in 1966. From that point, the Scimitar was relegated to training units and continued being used as a training aircraft until 1970 before being ultimately decommissioned from active service. In total, 76 Scimitars were built during their limited production run, of which 39 were lost on account of various accidents.

== Description ==

The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced as a [[wt:en/news/6444-development-swedish-aircraft-in-war-thunder-saab-j29d-jet-powered-fighter-en|premium pack]] in [[Update 1.93 "Shark Attack"]] and was removed from the store after the [[wt:en/news/7417-shop-war-thunder-birthday-sale-in-gaijin-net-store-en|9th Anniversary Sale]]. It was briefly made available for purchase with Golden Eagles {{GE}} for the [[wt:en/news/8339-special-two-fighters-and-a-decal-for-swedish-air-force-day-en|2023 "Swedish Air Force Day"]] mini-event.

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.

[[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 whopping 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 ===
{{Specs-Avia-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.

{{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.]]

{{main|srak m/55 Frida|psrak m/49A|srak m/51|hprak m/49}}

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

* Without load
* 24 x 7,5 cm srak m/55 rockets
* 14 x 14,5 cm psrak m/49A rockets
* 14 x 15 cm srak m/51 rockets
* 4 x 18 cm hprak m/49 rockets

== 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.

=== Pros and cons ===


'''Pros:'''

* Fast and agile
* Multi-role aircraft (fighter/attacker/interceptor)
* Four nose-mounted 30 mm akan m/55 autocannons
* Accelerates well in a climb
* Combat flaps handles speeds up to 800+ km/h.

'''Cons:'''

* Loses its agility at high speeds
* Tends to be up-tiered against planes which are faster
* Bleeds through ammunition quickly - requires trigger patience
* Guns have high recoil which pulls the nose down when firing making aiming and leading harder

== History ==

[[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 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 [[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 manoeuvrability 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. SFA (Svenska Flygmotor AB, today Volvo Aero), 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 [[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 ==

The '''Yakovlev Yak-1B''' is the second variant of the [[Yak-1 (Family)|Yak-1 fighter aircraft family]]. The Yak-1B debuted in the autumn of 1942 with a more powerful Klimov M-105P engine with improved low-altitude performance and a single 12.7 mm Berezin UB heavy machine gun instead of two 7.62 mm ShKAS light machine guns. Although this did not significantly enhance the total weight, it did result in a substantial increase in firepower. Other changes were electrical and pneumatic weapon firing instead of the mechanical system, a new control stick based on the Messerschmitt Bf 109's design, a new gunsight, an airtight fuselage, a retractable tailwheel, and enhanced engine cooling. "Yak-1B" was an unofficial designation; all Yak-1s were produced to this specification after October 1942. The first flight (aircraft No. 3560) occurred in June 1942, and manufacture of the Yak-1B began in August. There were 4,188 aircraft manufactured in total.

Introduced in the Open Beta Test prior to Update 1.27, the Yak-1B performs well at low altitudes, while high-altitude performance is still subpar. When compared to the standard Yak-1, structural strength is significantly improved. Despite the increase in firepower, the ammunition available is very limited. To avoid "spraying" the ammunition towards the enemy, the player must use tight trigger control. One significant disadvantage of this plane is the lack of Wartime Emergency Power (WEP); hence, it is critical to keep this in mind during fights to avoid wasting too much energy. Overall, the Yak-1B armament of a 20 mm ShKAS cannon and a single 12.7 mm Berezin UB heavy machine gun will serve as the foundation for several Yak fighter variants in the future.

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


This improved Yak-1 features, like most mid-war water-cooled fighters, a 1,210 hp engine. It remains sub-par to the German equivalent. However, at the time this plane was fielded, most enemy vehicles were of heavier weight, meaning that it could further utilize the Yak series' excellent manoeuvrability. However, the aircraft is tiered with earlier vehicles in-game, which shifts the performance spectrum of the Yak-1B towards engine power.

Like other Yakovlev fighters, the Yak-1B is a jack-of-all-trades, having good speed, turning ability, roll rate, and climb. Manoeuvring and vertical energy retention are good, so it does not lose much speed in turns and can perform vertical loops effectively. Energy retention in a straight line is decent. It is slightly heavier than the Yak-1 and the turning ability is negligibly worse. However, the new engine makes it one of the fastest aircraft at low altitudes when flying in a straight line. Under 1,000 meters, it can even outrun some 4.3 aircraft like the [[Pyörremyrsky]] by a slim margin.

While the climb rate is good, the engine was designed for low altitudes and the performance drops off drastically at higher altitudes. Power loss is noticeable above 3,000 meters and the aircraft will really start to struggle above 4,000 meters. Another issue is its poor high-speed characteristics. Like many other contemporary Soviet aircraft, the wings are made largely of wood and will rip at relatively low speeds compared to US or German fighters. Even before the rip speed is reached, it suffers from some compression issues. The roll compression starts to become noticeable above ~450 km/h IAS and the elevator suffers significantly above ~600 km/h IAS. While it does not compress as badly as the [[La-5]], combat manoeuvring becomes difficult at these speeds. Even if the wings do not snap, the pilot will easily black out.

The engine tends to run hot and without MEC it will, after quite a while, overheat at 100% throttle. Dialling down the throttle to about 96% will alleviate the issue with minimal performance impact. Alternatively, using MEC and opening the radiators slightly is enough to run it at 100% indefinitely. Note that the Yak-1B does not have a WEP setting in realistic battles.

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


* 64 mm Bulletproof glass in cockpit front and rear.
* 8 mm Steel plate behind the pilot.

Self-sealing fuel tanks are located in the wing roots and wing midsections.

The Yak-1B introduces thick bulletproof glass protecting the pilot and retains the armoured bulkhead behind the pilot's seat from the Yak-1. It is fairly unlikely that the pilot will be knocked out in head-ons as a result. However, the inline, water-cooled engine is very vulnerable to combat damage. The steel plate is enough to protect the pilot from rifle-calibre machine guns from the rear at medium distances, but cannon projectiles and heavy machine guns can still punch right through.

The rest of the airframe has decent constructional strength, though it is still not as hardy as contemporary US aircraft. Cannons and heavy machine guns will do a number on the Yak-1B. The wing fuel tanks are vulnerable to damage in deflection shots and fires will be a common cause of destruction.

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

With the Yak line of fighters, '''always''' research the engine and performance modules first! Adding power upgrades will help to lower the overheating of the engine. Afterwards, the aircraft modules can be unlocked in any order according to pilot preference. The Survivability modules are recommended next, as they improve the Yak-1B's manoeuvrability and survivability even more. The Armament modules improve the aircraft only by adding ammo belt types available and allowing the usage of 100 kg of bombs.

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

{{main|ShVAK (20 mm)|Berezin UB (12.7 mm)}}

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

* 1 x 20 mm ShVAK cannon, nose-mounted (120 rpg)
* 1 x 12.7 mm Berezin UB machine gun, nose-mounted (200 rpg)

The Yak-1B is equipped with standard armament for most Yakovlev aircraft: one machine gun and one ShVAK cannon. With 200 and 120 rounds respectively, this is nothing out of the ordinary for this series. It's good against enemy light fighters, but larger aircraft like bombers or twin engine fighters will not go down too easily due to the relatively low burst mass. If forced to engage these tougher targets, try to knock out defensive gunners first and then set the engines on fire with a few accurate bursts.

The ShVAK cannon is an inconsistent weapon in terms of damage, and its main positive attributes are high accuracy and rate of fire. The best belts for it are Default or Armoured targets, though some players use Ground, and some Tracers. As of mid 2023, the HEF rounds implementation has been fixed, so it is no longer necessary to avoid belts containing HEF rounds, which used to spark. The Berezin UB heavy machine gun's Cermet-core rounds in the Ground targets belt can rip through enemy aircraft effectively and the Air targets belt is spectacular at starting fires. Air targets is usually the way to go, but feel free to experiment with the others. The ShVAK and Berezin have similar enough ballistics that they can be used together at close to medium range. For harassing targets at somewhat longer distances, use the Berezin in short bursts since it has slightly better ballistics, more ammo to spare, and might start a lucky fire.

If both weapons are fired together, the ShVAK will run out first and the Berezin will be left with around 50 rounds, which is rather insufficient for typical engagements and should indicate that it is time to return to base.

Convergence is generally a non-issue since the guns are mounted tightly in the nose. It is best to either set a relatively high convergence distance (e.g. 600 m) or turn it off entirely.

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

{{main|FAB-50sv (50 kg)}}

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

* Without load
* 2 x 50 kg FAB-50sv bombs (100 kg total)

The Yak-1B cannot use the 100 kg bombs available to the Yak-1. The two 50 kg bombs it does have are very weak and there is generally no reason to equip them at all. They need to be dropped almost directly onto ground targets to cause any damage. For ground attack, other aircraft will do a much better job.

== Usage in battles ==

=== Arcade Battles ===
The Yak-1B is simply an upgraded Yak-1. The main features that the Yak-1B has over its counterpart is much-improved cockpit visibility, slightly better durability, and a slightly more resilient engine that still overheats, but it has been changed since the eraly days and you can climb at 100% throttle to 4000m and it will only be yellow. The beauty of the Yakovlev line of fighters lies in two things:

*Overheating can be fixed by flying at or slighly below 97% throttle.
*The Yak's performance is not hindered in the slightest by flying at this engine power.

Due to the above two facts, in AB: fly at 95% to 97% power. The Yaks can dogfight just fine at 97%, and will rarely overheat. Even though in Arcade battles all planes get WEP, the WEP on this plane adds almost nothing to its performance while rapidly overheating the engine, thus using WEP is practically unnecessary. If you find yourself in a situation where your aircraft needs more power, throttle up to 100% power, however, remember to throttle back down once you can.

Wait for the dogfight to start, then fly in behind a distracted enemy. Shoot in bursts unless tailing a bomber, in which case you will not last very long against their rear gunners unless you are incredibly accurate with the cannon. If your engine begins to overheat, start flying back to your airfield. Otherwise, your engine will give out after the temperature gauge turns red.

To sum up, this is merely a better version of the Yak-1, with similar tactics and strategy. Just remember that Soviet fighter aircraft in general count heavily on its pilot's accuracy, in this case only have two guns!

=== Realistic Battles ===
Overheating has been much decreased since the early implementation. If not using MEC, take off at 100% throttle, then go to 97% after getting to 3000m to 4000m. If using MEC, open the radiators somewhat (~20-30%) and turn up the prop pitch (~90%). This will keep the engine cool, allow you to run the throttle at 100%, and also bring out extra propeller thrust for better climb and acceleration. '''Stay low at all costs!''' If you climb too high, four things will happen:

# You will have run your engine out trying to climb, so your engine has less time before it overheats than usual. Note: Overheating is much less prevalent now (mid 2023) than it used to be. (You also don't climb as fast as most other planes, in fact, there are better Soviet aircraft for climbing, such as the MiG-3 and the La-5).
# You will be highly visible.
# You will have reduced manoeuvrability.
# You will easily rip your wings upon trying to dive (The Yak's wings, is made of wood, disappear at about 600 km/h).

If you stay below 3,000 m, then you will have more advantages than the enemy, such as:

# There is less chance of ripping wings.
# You are already at optimal altitude and speed for manoeuvring.
# Enemies easily overshoot you or rip wings attempting to dive on you.
# You can trick enemies into flying into the ground (make sure you don't do so yourself!).

Flying at 95% to7% throttle setting in Realistic Battles is enough to fight at below 1,000 m (some experienced Yak pilots will even dogfight at 80% throttle!).

While the Yak-1B has stellar performance at very low altitudes, it is still a good idea to climb a bit, perhaps to at least 2,000 meters. This gives you more options when an enemy dives in from above. Dodging them with a hard break is a reliable option, and when performed correctly this will sometimes lead to manoeuvre kills, but the enemy can also escape by zoom climbing up, where you will be unable to follow. Essentially, you will be at their mercy unless they become impatient and attempt to dogfight you. Enemies like Spitfires that combine manoeuvrability and altitude advantage will be difficult opponents even if they engage in a dogfight! If you start with some altitude, you can enter a dive to gain speed once they start to get close, then level out and take advantage of the Yak-1B's excellent low-altitude top speed. If the opponent continues to chase you, they will likely run out of bonus speed from the dive and fall behind, neutralizing their energy advantage. If they wisely break off, you can nose up and return to cruising altitude with little energy lost, waiting for another opportunity. Successfully executing this can take a lot of practice, but it is a very useful skill, and not just for Yaks.

The Yak-1B manoeuvres best at around 400 km/h IAS, where its roll and turn rate are optimal. Descending in a turning spiral is a good way to maintain this manoeuvring speed and drag fights down to lower altitudes, where other Soviet aircraft tend to perform better, but obviously review the situation and see if vertical loops, rolling scissors, or other dogfight manoeuvres would be more suitable. The Yak-1B does well in all of these provided that an eye is kept on the speed. Do not go fast enough that the compression becomes an issue, but also avoid getting extremely slow. Take advantage of the landing flaps and strong rudder as necessary when nosing over from a vertical loop, continuing a climbing spiral, or stall climbing.

It is recommended to avoid firing at ground targets due to the limited ammunition available for use against other planes. Remember that you do not reload in mid-air in Realistic Battle, so ammunition conservation is critical while closing the distance with the enemy before firing. Remember, fire only in short bursts to conserve ammunition and avoid jamming the guns. The great thing about the Yak's guns is that they are centre-line mounted. Guns mounted in the propeller shaft mean that you do not have to worry about convergence points, instead lead the target and snipe. The drawback is that you cannot spray the mark with a hail of bullets like most players tend to do. This plane and all the Yaks afterwards are about accuracy and skill necessary to handle this agile plane. Do not commit to head-ons, as the Yak-1B is rather fragile and the burst mass is not enough to reliably win these engagements.

When landing, slow the aircraft to BELOW 300 km/h before lowering the landing gear! Many Yak pilots have ripped their landing gear when descending too fast with them extended. The last thing all Yak pilots should know in Realistic Battles is preferably not to climb higher than 3,000m to 4000m (at or below 2,000 m is preferred). The Yak line of fighters was not built to fight at the higher altitudes, and the game is filled with much more capable aircraft in this respect. If you like B&Z or you prefer to climb high, but don't want to use the US or German planes, then use the MiG line or the LaGG/La line of fighters, as they have better high altitude engines. The Yak is a dog-fighter.

===Tips from the Aces===

* A Yak pilot can nullify all but the last "[[Yak-1B#Pros_and_Cons|Cons]]" below by staying below 2000 m, and keeping the throttle at 90% for AB, and 95% for RB/SB, or using MEC.
* ''If the situation allows'', using in-cockpit view can often help with accuracy due to no parallax effect... meaning (hopefully) less of your precious shots wasted.
* Flaps help with hard turns, but against most opponents, flaps will not be utilized much. Use flaps wisely, since flying at ~95% means a tiny bit less engine power to get back to speed after slowing down due to using flaps. However, don't hesitate to use flaps if the fight depends on it, it is easier to regain speed than to pay for a new plane!
* Everything learned from the Yak-1B applies to all of the later Yaks. Mastering this plane will repay itself in gold later.

===Specific enemies worth noting===


* [[A6M2|A6M2 Zeroes]]: They will out turn you, so try to attack in a shallow dive rather than a turn fight. Energy fighting is also okay because the Zero has poor energy retention and terrible high-speed control and handling. Never dogfight a Zero on its terms and be sure to keep a speed/energy advantage at all times. If things go south, break off and run away - the A6M2 is very slow.
*[[P-47_(Family)|P-47Ds]]: They are much faster than you and are excellent at boom and zoom, so avoid them if possible. If you are caught in a fight, try to energy fight them or turn to fight them.
* Other [[Yak-9 (Family)|Yakovlevs]]: They are slightly slower, so either keep them occupied with manoeuvres such as the scissors and barrel rolls or energy fight them.
* [[Spitfire_(Family)|Spitfires]]: They are significantly slower but turn nearly as well as Zeros. Their early Hispano cannons, while inconsistent, are still not good to be hit by, and early models can unleash swarms of rifle-calibre bullets that can ignite the Yak-1B easily. Spitfires also tend to have good climb rates and somewhat better high altitude performance, so seeing them diving from high altitudes is not uncommon. Try to drain their speed and avoid letting them get too close to you. It is difficult to shake a Spitfire from your tail if they have already latched on at close or medium range - running away in level flight can result in taking fire, and dodging will drain your speed and make escape difficult.
* [[J21A-1]]: This Swedish pusher-prop has excellent speed and climb in addition to surprisingly good agility and monstrous firepower. Never commit to a head-on against one, doing so usually results in a direct trip to the hangar. The Yak-1B has the advantage in turn time, but not by a large margin. Dodge their attacks as best as possible and try to bait them into turning. The J21 tends to bleed energy in extended or hard manoeuvres and has issues gaining it back. If you can survive the first few turns, the engagement will be more favourable, making it easier for you or your teammates to knock the J21 out. But never let your guard down.

The Yak-1 is a Soviet single-engine fighter of the WWII era. It was the first combat aircraft designed by Alexander Yakovlev's construction bureau and was produced from 1940 to 1944, with a total of 8,700 aircraft built. The Yak-1B variant was a culmination of all 1942 efforts to improve the Yak-1. Work began at TsAGI, where research into improving the water and oil radiators took place between 24th May and 10th June 1942, and work to increase the top speed was conducted between 20th and 26th July 1942. Tactical characteristics of the Yak-1 were significantly improved as a result, leading to Yakovlev's request to the Minister of Aviation to mass-produce a test batch of 20 improved aircraft for combat testing at the front.

However, the improvements looked so good on paper that a test batch was skipped, and a Defence Committee Directive dated 11th August 1942 ordered a new and improved Yak-1 into mass production. Improved armament triggers and a cockpit with improved rearward visibility were welcomed by Soviet pilots and became standard on all contemporary Soviet fighter planes.
