The Nakajima Ki-84 Hayate (Japanese windstorm) is a Japanese single-engine single-seat fighter with a half-shell, all-metal structure in a low wing structure. The prototype flight took place in April 1943, and from 1944 the machine entered the line. The Ki-84 was the most important Japanese fighter at the end of the war, with excellent flight characteristics, top speed and maneuverability. He was able to engage in an equal fight with the Allied machines without any problems. Also, unlike the much better known Zero, it had good armor, strong shooting weapons and self-sealing fuel tanks, which made it a very dangerous opponent. The main mass-produced version is the Ki-84-I with several versions, powered by a Nakajima Ha-45 engine of various models, the most widely used of which was the 23 (1900HP). Ki-84 of this series served min. in China, Okinawa, and defended the Japanese islands against Allied air strikes. It is worth noting that in the declining period of the war efforts were made to replace scarce aluminum with wood or steel, but such versions of the Ki-84 were never produced on a large scale. All versions of the Ki-84 were produced 3,514 copies.
