Kawasaki Ki-64

The experimental interceptor fighter aircraft of the Imperial Japanese Army Air Force the Kawasaki Ki-64 Rob.
Only a single prototype built during the middle of WW2 in 1943 and was probably one of the fastest propeller driven planes of Japan, reaching 690km/h maximum speed!
It was an innovative design incorporating contra-rotating propellers with tandem geared engines (one in the front and one behind the pilot) and to cool these engines the designers used the wings as giant radiators.
