The Rikugun Ki-93 was a prototype Japanese twin-engined fighter aircraft of the Second World War. It was the last heavy fighter and ground attack aircraft built in Japan during the war and was the only design by Rikugun K.K. to be flown. The project began in February 1943 with plans to start with a number of prototypes. The Ki-93 was distinctive looking in that it had a ventral gondola slung under the fuselage to accommodate a large caliber cannon. Two variants were planned, the Ki-93-Ia bomber destroyer, armed with a 57 mm and two 20 mm cannon, and the Ki-93-Ib anti-shipping aircraft, which would have a 75 mm gun in the gondola and would also carry two 250 kg (550 lb) bombs. The sole example of the Ki-93-Ia bomber destroyer made its first flight on 8 April 1945 but was seriously damaged on landing. Before the repaired aircraft could be flown again, a B-29 bombing raid on Tachikawa destroyed the hangar housing the airframe. A second prototype (of the Ki-93-Ib ground attack configuration) was completed but not flown before the end of the war.
