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. The Kasei (Mars) was the largest of the manufacturer’s original 14-cylinder radials, and was widely used in various models. It was geared, supercharged, and had optional water methanol injection. Between 1941 and 1945, 9,323 engines of all models of the Kasei 20 series were manufactured.; This Model 21 powered the Mitsubishi G4M twin engine attack bomber (Allied Code Name Betty) built in larger numbers than any other Japanese bomber; it was used from the beginning of the war and also transported the Japanese surrender delegation. A total of 2,446 G4M and the similar G6M1 aircraft were built.
