The Nakajima Ki-84 Hayate (Gale) first flew in March of 1943. It was the only Japanese Army fighter with a four blade propeller. It became combat operational flying out of Hankow, China in 1944. Later they were based in Japan, Okinawa, the Philippines, Southeast Asia, and Taiwan.

At 20,000 feet the Nakajima Ki-84 was faster than a P-51 and had a better rate of climb. It could out turn a Spitfire. A captured aircraft, when run on high octane gasoline, had a top speed of 428 mph.

Having learned their lessons from previous fighter aircraft, the Nakajima Ki-84 had armor plating for pilot protection. Its pilots also enjoyed acceleration, maneuverability, and climb rates unmatched in previous Japanese aircraft.

It is said that at medium altitudes, the Nakajima Ki-84 Hayate could out run and out distance any Allied fighter aircraft. However, ground handling of the aircraft was not good. The aircraft had limited forward visibility when taxiing, and pilots had to be ready to compensate for high engine torque when the aircraft rotated on take off.

As with many aircraft rushed into production, the Nakajima Ki-84 Hayate suffered from a number of quality defects. One of the most prominent was a tendency for landing gear struts to fail during hard landings. This was due to improper metal hardening during the manufacturing process.

In addition to being used as an interceptor and fighter, the aircraft saw limited use as a fighter/bomber. In April of 1945 Nakajima Ki-84 Hayate aircraft attacked Okinawa air fields occupied by the United States. A number of U.S. bomber and fighters were put out of action by the surprise attacks.

It is argued that if the Nakajima Ki-84 Hayate had been introduced earlier in the war and in sufficient numbers, it would have been a huge threat to the Allies.

After World War II, the aircraft continued to be flown. The Chinese flew them into the 1950's.

A total of 3,449 Nakajima Ki-84 Hayate fighters were produced.
