This exceptionally clean aircraft was designed to meet a May 1943 specification for a long-range escort fighter. The designer Tomio Kubo used his experience with the Ki-46 aircraft to design the Ki-83. The first prototype was completed in October 1944, and its maiden flight was on November 18, 1944. Testing showed the aircraft to have spectacular performance and exceptional maneuverability for its size. The JNAF expressed an interest in acquiring part of the proposed production run, and other versions were also put into the planning stages (including the more advanced version known as the Ki-103, and the Ki-95 which was to replace the Ki-46 command reconnaissance plane). Production of the Ki-83 or its derivatives never took place, however, as by that stage of the war the Japanese had a greater need for interceptor fighters.
