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.

  • 70 mm sloped (66°) bulletproof glass in the windshield
  • 13 mm steel plate behind the pilot seat
  • 6 mm steel headrest

Armaments

Offensive armament

The Ki-84 hei Hayateis armed with:

  • 2 x 30 mm Ho-155 cannons, wing-mounted (60 rpg = 120 total)
  • 2 x 20 mm Ho-5 cannons, nose mounted (150 rpg = 300 total)

Suspended armament

Pros:

  • Equipped with a very powerful array of weapons
  • Respectable speed for a prop plane
  • Decent high altitude performance
  • Capable turner
  • Solid energy retention
  • High muzzle velocity from both cannons

Cons:

  • 30 mm cannons are mounted in the wings, resulting in significant convergence
  • 30 mm cannons fire fairly slowly, which isn't ideal for dogfighting
  • Poor ballistics from the 20 mm cannons at this rank
  • Can and will face early jet fighters, which negate your speed advantage
  • Useless when the engine's shot
  • Airframe is highly susceptible to battle damage, especially of the incendiary type

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: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