Kawanishi J3K

The Kawanishi J3K, formally the Navy Kawanishi 17-shi Interceptor Fighter Otsu (B), was an interceptor fighter developed by the Japanese company Kawanishi Kokuki KK in the early 1940s. It was designed in parallel with the better known Kawanishi N1K-J Shiden but was abandoned in the early stages of development. The design called for a single Mitsubishi MK9A 18-cylinder two-row air-cooled radial piston engine of 1,600 kilowatts (2,200 horsepower) driving a four-bladed constant-speed propeller, in an airframe 10.12 metres long with a wingspan of 12.5 metres and a maximum takeoff weight of 4,370 kilograms. Its projected maximum speed was 685 kilometres per hour with a service ceiling of 10,800 metres, and it was to be armed with two 13.2 millimetre Type 3 machine guns and two 30 millimetre Type 5 cannon. A further development of the design was the Kawanishi J6K.
