Mitsubishi Ki-83


Intended to meet a requirement formulated in 1943 for an advanced two-seat long-range escort fighter. the Ki-83 was designed by a team headed by Totnio Kubo, who had previously been responsible for the Ki-46.

Aerodynamically exceptionally clean and powered by two turbo-supercharged Mitsubishi Ha-211ru 18-cylinder radials, the Ki-83 possessed an armament of two 20-mm and two 30-mm cannon.

The first of four prototypes was flown on 18 November 1944, demonstrating spectacular performance and remarkable maneuverability for its size - a 2,200-ft (670-rn) diameter loop being executed at 403 mph (648 km/h) at 9,500 ft (2900 m) within 31 sec. However, definitive plans for the series manufacture of the Ki-83 were still being finalised when hostilities terminated.
