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.

This engine is of the type that powered World War II Japanese reconnaissance, fighter, bomber, and assault aircraft with Allied Code Names Dinah, Nick, Judy, Tony, Randy, Edna, and Zeke 54 and 64. It was a geared, supercharged, and fuel injected engine with water-methanol injection optional. Between 1940 and 1945, 3,725 Ha 33 Model 62 engines were built.
