The A21A-3 has a poor climb rate and fairly low acceleration, making it ineffective as an energy or boom-and-zoom fighter unless you commit to a side climb. The aircraft has great turning characteristics at almost all speeds, and maintains speed in horizontal turns well enough, though it will stall quickly in any vertical manoeuvres. The aircraft maintains most of its turning ability with heavy loads, but suffers greatly in climb ability. If you wish to take an altitude advantage, forgo any loads.

Boasting extremely good turning characteristics, a stable platform, decent speed and accurate, powerful guns, the A21A-3 is an extremely effective aircraft for both dogfighting and ground attack duties. The Swedish 13.2 mm Akan m/39A guns are devastating to lighter aircraft thanks to their anti-air belts with plentiful HE, and the nose mounted 20 mm cannon makes short work of larger targets as long as you are accurate. In air-to-air battles, the aircraft is best suited to catch opponents low on energy. Only a few aircraft at its BR are able to turn as well as the A21A-3 at low altitude, and the aircraft remains stable even in low speed turns to keep guns on target. It is wise to keep fights short though, as the A21A-3 is a terrible climber, and is an easy target for boom and zoom fighters if engaged in a fight.
 
−
 
 
−
On the other hand, the A21A-3 makes for an extremely effective ground-and-pound aircraft, capable of destroying an enemy base with its 600 kg bomb in some air RB game modes, access to some of the best rockets weight-for-weight at its battle rating, and a significant amount of ammunition for its guns to attack ground units. The aircraft's low speed stability makes short dipping attack runs on ground units easy, and the good firepower means you don't have to stay on target for too long.
 
−
 
 
−
The quad 13.2 mm machine guns get access to high-explosive rounds, which are very potent when attacking smaller ground targets, such as Howitzers, AA and armoured cars, often requiring a very short burst to take care of them. The 20 mm cannon is able to destroy light pillboxes. However, quite large bursts are required to take them down. 
 
−
 
 
−
It is important to take care that enemy aircraft do not get a chance to attack you from behind, however. The A21A-3, as a pusher aircraft, can be brought down quickly when tailed. The engine is poorly armoured, with a tiny water and oil reserve and runs at a high temperature. Additionally, there is a fuel tank between the cockpit and engine which will not survive even a glancing hit. If you are attacked and suffer an oil or water leak you will need to land at your base as quickly as possible, the engine will burn out within minutes of an overheat. The large control surface of the tail is also a vulnerability.
 
−
 
 
−
In ground RB, the aircraft can perform well at almost any BR, as its 600 kg bomb can be used effectively to clear points and entrenched enemy tanks of any size with a whopping 18 m destruction range, with a fighter's SP cost it can be an invaluable CAS asset to a team.

The [[J21 (Family)|SAAB 21]] was a twin-boom propeller fighter used by the Swedish air force. A unique design, it had a pusher-configuration engine and a twin-boom tail, giving it a very unique appearance. The A21A-3 was a variant of the SAAB 21, designed for ground attack. As a result, it was equipped with a bomb sight, and was able to carry suspended ordnance and a RATO (Rocket-assisted takeoff) pod. 66 A21A-3 aircraft were built between 1947 and 1949, and served as the primary ground attacker until the introduction of more capable jet aircraft.<ref name=":0">Aceto, G. (2019)</ref>

−
=== Design and development ===
 
−
In the early 1940s, it was apparent that Sweden badly needed a new fighter aircraft. Thus, Sweden ordered SAAB to design a new aircraft based on the German Daimler-Benz DB 601, 603 or 605 engine. At that time, the German and Swedish had a series of neutrality agreements, allowing Sweden to import the German-made aircraft engines.<ref name=":0" /> One radical configuration considered was a twin-boom aircraft, similar to the P-38 Lightning, but with a single rear-mounted engine in pusher configuration. However, SAAB was initially asked to instead produce the J23, a more conventional aircraft design.<ref name=":0" />
 
−
 
 
−
In late 1941, the Swedish air ministry reverted on its previous decision and asked the SAAB firm to produce the J21 design. Thus, design work progressed through 1942 and 1943. The final prototype featured a twin-boom wing with a single DB-605B engine, and carried a main armament of one 20 mm cannon along with four 12.7 mm heavy machine guns. The first prototype flew in mid-1943, but was quickly revealed to have inferior performance to the [[Fw 190 (Family)|Fw 190]], [[Spitfire (Family)|Spitfire]] and [[P-51 (Family)|P-51]] Mustang. However, 484 aircraft were ordered anyway.<ref name=":0" />
 
−
 
 
−
In 1945, SAAB began designing a series of second-generation J21 aircraft designed specifically for the air-to-ground role. This resulted in the A21A-3. The aircraft had a bombsight, and was able to use RATO (Rocket-assisted takeoff) pods, bombs or rockets. The Swedish Air Force eventually ordered 66 aircraft between 1947 and 1949.<ref name=":0" /><ref name=":1">Editors of Military Wikia. (2020)</ref>
 
−
 
 
−
=== Operational History ===
 
−
The A21A entered service in 1947, but had an extremely short service life. The aircraft's poor performance and relative obsolescence meant that it served for an extremely short time. The 66 A21 aircraft built were quickly replaced by the more modern [[J29 (Family)|J29]] Tunnan and British de Havilland [[J28B|Vampire]]. The last A21A aircraft were retired in 1954. However, it is worth noting that SAAB also experimented with coupling a jet engine to the J21 airframe; this resulted in the [[A21RB]], a unique aircraft coupling the J21's fuselage with a de Havilland Ghost engine.<ref name=":1" /> Three A21A aircraft survive, all kept in Swedish museums.<ref name=":0" /><ref name=":1" />

Usage in battles

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

Pros and cons

Pros:

  • Very manoeuvrable, even with wing-tip fuel tanks
  • Very stable, does not stall in level flight even with the throttle set to zero
  • Engine protected from head-on attacks
  • Most armament is nose-mounted

Cons:

  • Pusher aircraft, engine mounted facing rear, exposed to enemy aircraft which may follow
  • Required to set convergence due to wing-mounted machine guns

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
