Survivability and armour

Protective components found in the J21RA.
  • 10 mm steel - Firewall armour plate
  • 10 mm steel - Firewall cover armour plate
  • 10 mm steel - Pilot's back armour plate
  • 60 mm bulletproof glass

Armaments

Offensive armament

The J21RA is armed with:

  • 1 x 20 mm Akan m/45 cannon, nose-mounted (140 rpg)
  • 2 x 12.7 mm Akan m/39A machine guns, nose-mounted (350 rpg = 750 total)
  • 2 x 12.7 mm Akan m/39A machine guns, wing-mounted (325 rpg = 650 total)

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft 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).

Modules

Tier Flight performance Survivability Weaponry
I Fuselage repair Offensive 20 mm
II New boosters Compressor Airframe Offensive 12 mm
III Wings repair Engine New 20 mm cannons
IV G-suit Cover New 12 mm MGs

Pros and cons

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

Cons:

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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></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).

Media

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

See also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:

  • reference to the series of the aircraft;
  • links to approximate analogues of other nations and research trees.

External links

Paste links to sources and external resources, such as:

  • topic on the official game forum;
  • encyclopedia page on the aircraft;
  • other literature.
