The Ki-84 hei Hayate is a rank IV Japanese fighter with a battle rating of 6.7 (AB) and 6.3 (RB/SB). This aircraft was introduced in Update 1.37.

General info

Flight Performance

The Hei Hayate is the exact same plane as the Ko and otsu - same good turn rate, climb rate, and compression. Having flown those two, the Hei Hayate is quite literally the exact same. As with the other two, use your excellent vertical energy retention and good maneuverability to your advantage. You can outturn all allies except the Merlin Spitfires and the P-59 using combat flaps. You still retain the OK roll rate and abysmal rudder of the other Hayates.

Survivability and armour

  • 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

The Ki-84 hei Hayatecan be outfitted with the following ordnance:

  • Without load
  • 2 x 50 kg Army type 94 GPHE bomb
  • 2 x 250 kg Army type 92 GPHE bomb

Usage in battles

The Hei Hayate is the same great Hayate but with 2x 30 mm cannon instead of 2x20 mms. Although this might not seem too important, one hit from a HE 30mm shell will easily send your enemies to their doom. This solves the problem of the lacklustre 20 mms. When up-tiered to jets, focus on taking out propeller-powered aircraft. Climb high, and kill. Once all the props are down, look for furballs and/or ground-pounding jets. Swoop down on these people and destroy them. When jumped by a jet, there are a few things you can do such as pulling evasive manoeuvres and wearing the enemy's energy down. Call out for your jet teammates to help you out. When there is one more person running away, unless they are a bomber (which are typically easy to catch) or a prop fighter, will not be much for you to do. Just go to the airfield, repair, and "J"-out. Equip ground target rounds and bombs and try to wear down the tickets. Remember not to die. Survival is more important than ever in the Hei Hayate - your astounding repair cost means that you need to take down at least three air targets before breaking even with this aircraft's repair cost!

Pros and cons

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
  • Insta-kill 30mms

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

The IJAAF approached Nakajima in 1942 to upgrade it's Ki 43 fighter. They realised the need for a more solidly armoured, faster, and heavier armed fighter. Addressing the common complaints with the Ki 43 which were low speed, lack of armour, and measly armament, the designers at Nakajima unleashed the Ki 84 - Japan's fastest propeller-driven fighter. Using the firm's own Homare, the Ki 84 was easily able to keep up and dogfight with the P-51 and P-47. The Hayate was produced in three modifications which happened to be the same aircraft with different armament options. These three are available to fly in-game.
