The Nakajima Ki-44 was a single-engine 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"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 Superfortress bombers. With its poor visibility on the ground, weak armament, and high landing speed, it was generally disliked by pilots.
