Rikugun Ki-93

The Rikugun Ki-93 was a prototype Japanese twin-engined fighter aircraft of the Second World War. Designed by the Army Aerotechnical Research Institute, to be a heavy fighter armed with large calibre cannon to serve in the anti-shipping or bomber destroyer roles, only one example of the Ki-93 was completed; this was damaged on its maiden flight, and destroyed by American bombing before it could be flown again.
