Summary
Mitsubishi was the first and largest series producer of Japanese engines during World War II, with a 1937 Pratt & Whitney arrangement possibly contributing to this success. Its Kinsei (Golden Star) engine saw service throughout the war, beginning at 544 kW (730 hp) and producing as much as 1,163 kW (1,560 hp) at war’s end.
The Kinsei 44 powered the Aichi D3A, (Allied name "Val") which was the primary carrier-borne dive bomber of the World War II Japanese Navy. It was the first Japanese aircraft to bomb American targets, commencing with Pearl Harbor and U.S. bases in the Philippines. During the course of the war, it sank more Allied warships than any other Axis aircraft
