The Kawasaki Ki-64 to meet a 1940 specification for a fighter capable of 435 mph and reaching 16,400 feet in five minutes. The resulting design was interesting in that it used the Kawasaki Ha-201 engine, which was actually two Ha-40 12-cylinder engines mounted in tandem fore and aft of the pilot's cockpit, which drove two contra-rotating propellers. Another unique feature of the Ki-64 was the steam vapor cooling system for the engines, which was installed in the wings. First flights occurred in December of 1943. A production version with a more powerful engine was believed to be capable of 497 mph, but the project was canceled in favor of more conventional aircraft already in production.
