The Nakajima Ki-84 Hayate (疾風, "Gale") was a single-seat fighter used by the Imperial Japanese Army Air Force in World War II. The Allied reporting name was "Frank"; the Japanese Army designation was Army Type 4 Fighter.
Featuring excellent performance and high maneuverability, the Ki-84 was considered to be the best Japanese fighter to see large scale operations during World War II. It was able to match any Allied fighter, and to intercept the high-flying B-29 Superfortresses. Its powerful armament (that could include two 30 mm and two 20 mm cannon) increased its lethality.
Though hampered by poor production quality in later models, a high-maintenance engine, a landing gear prone to buckle, and lack of experienced pilots above all else, Hayates proved to be fearsome opponents. Exactly 3,514 aircraft were built.
