――The Type 5 fighter is a type that has been replaced with the air-cooled radial engine Ha 112 in a hurry in response to the increase in neckless Hien due to the production delay of the Ha 104 liquid-cooled engine.
――In order to mount a radial engine larger than the fuselage width on the aircraft originally designed as a liquid-cooled engine, the Kawasaki design team under Takeo Doi made hard efforts and completed this modification in an extremely short time. I did.
――The result is that although the maximum speed was slightly lower than that of Hien due to the increase in the frontal area, the climbing performance was improved by removing the cooling system, and the overall balance was extremely good, so the fighting performance and takeoff and landing characteristics were significantly improved. It has improved and is now able to challenge more than equal air battles against the F-6F Hellcat and P-51D Mustang.
--The Type 5 Battle, which succeeded in its first flight in February 1945, was immediately focused on mass production as a hope for the mainland air defense battle, and was focused on the 244th, 5th, and 59th squadrons. Although he was active in the mainland air defense battle, only about 390 aircraft were produced due to the bombing of the factory due to the air raid, and the war was defeated without becoming a large force.
