The Ki-44 Shoki (鍾馗、”Demon”) was a single-engined fighter aircraft used by the Imperial Japanese Army Air Force in World War II, first flying in August 1940 and entering service in 1942. The Allied codename was “Tojo”; the Japanese Army designation was “Type 2 single-seat fighter” (二式単座戦闘機).
In contrast to its predecessor, the nimble Ki-43, the Ki-44 was designed for speed and climbing ability, and was used to intercept high-flying B-29 bombers. With its poor visibility on the ground, weak armament, and high landing speed, it was generally disliked by pilots; its oversized engine and diminutive tail made it one of the more unattractive aircraft of its class.
This fighter once equipped twelve sentais of Japanese squadrons (9, 22, 23, 29, 47, 50, 64, 70, 85, 87, 104, 246) encountered in action before replacement with Nakajima Ki-84 ‘Franks’ for the final battles of the war. Manchoukouan Air force received some examples of these airplanes during wartime.
