Comments:
    The early months of World War II in Europe showed the Japanese that there would be a possible need for a heavier fighter. Going against the Japanese trend of manoeuverability over all other attributes, the Ki 60 design focused on speed and rate of climb with a heavy armament.
    A development contract was placed with Kawasaki in February 1940 for a cannon armed fighter with a liquid cooled engine. Kawasaki had recieved a license to build the Daimler-Benz line of engines and it was decided that the new aircraft should be designed around the DB 601A.
    The first prototype suffered from high wing loading which resulted in excessive take-off and landing speeds. The second and third prototypes had revised wings but this did little to improve the aircrafts shortcomings. The pilots of the Japanese Army Air Force were less than impressed with the performance of the aircraft and demanded changes. Over-all this aircraft performed dismally and combined with a lack of firm support for a heavy fighter concept the design was abandoned in late 1941.
