The Kawasaki KI-100

The Kawasaki KI-100, is the latest Japanese fighter to enter service before the end of the war. 

Based on the cell Kawasaki Ki-61-II KAI was equipped with a radial 1500 horsepower engine Mitsubishi Ha-112-II. This engine 14 double star air-cooled cylinder was known in the Navy under the name MK8P 'Kinsei 62' and cross-arms name was "Ha-33".

The study of the installation of a radial engine on a fine fuselage designed for a narrow V engine was not easy. But the Japanese had a Fw190 which had allowed the installation of the engine on the same dive bomber Yokosuka D4Y3.
This strange transplant yet made an excellent fighter. Mainly due to the general reduction of a very successful aircraft. Indeed, the empty weight of 315kg was lower compared to the Ki-61-II KAI also having an engine 1500ch. However, the top drag caused by the radial engine somewhat reduced the top speed.

275 Ki-61-II cells without engine, we assembled the Ki100-Ia release. The armament was that of Ki-61-I-K AId namely Ho-5 two 20mm guns in the hood and two Ho-103 machine guns of 12.7 mm in the wings.

The unexpected success of the Ki-100-Ia caused the production of new cells with glass bubble: KI-100-Ib. This glass was inspired by that of Ki-61-III that never saw the light. The Ki100-Ib was made because of only 106 copies in the chaos of the end of the war.

It was a great device that could take advantage on the F6F and F4U US Navy and even serenely face the P-51 USAAF.
