|This page is about the Swedish fighter A21A-3. For other versions, see J21 (Family).|
The A21A-3 is a rank IV Swedish fighter with a battle rating of 3.7 (AB/RB/SB). It was introduced in Update 1.95 "Northern Wind".
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.

Usage in battles
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 13.2mm Akan m/39A guns are devastating to lighter aircraft thanks to their anti-air belts with plentiful HE, and the nose mounted 20mm 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 600kg 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.
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' 600kg bomb can be used effectively to clear points and entrenched enemy tanks of any size with a whopping 18m destruction range, with a fighter's SP cost it can be an invaluable CAS asset to a team.

Pros and cons
- Quite manoeuvrable, even with wing-tip fuel tanks
- A stable flying platform, does not stall in level flight even with the throttle set to zero
- Engine protected from head-on attacks
- Most armament is nose-mounted
- Armed with extremely powerful 13.2 mm guns with decent ammunition pool and destructive AA belts
- Access to powerful and accurate rockets and devastating bombs for ground RB
- 600 kg bomb can destroy an enemy base in some air RB game modes.
- Pusher aircraft, engine mounted facing rear, exposed to enemy aircraft which may follow
- Required to set convergence due to wing-mounted machine guns
- Terrible climb rate, despite decent acceleration
- Loses speed in vertical manoeuvres extremely quickly
- Lacks airbrake
- Fragile and vulnerable from rear attacks, even water or oil leaks will tend to cause the aircraft to crash as the engine burns out quickly.
- Engine overheats quickly when on WEP
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></ref>, as well as adding them at the end of the article with
<references />. 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).
Excellent additions to the article would be video guides, screenshots from the game, and photos.
