Summary: The very large Mitsubishi organization was the first Japanese firm to mass produce high power aircraft engines, and it manufactured more of them (38 percent of Japan’s total) than any other Japanese company during World War II. Most of their better wartime engines evolved from models developed under license from Pratt & Whitney, Gnome-Rhone, Renault, Hispano-Suiza, and Armstrong Siddeley.; The Mitsubishi Kasei (Mars) was one of the most important 14-cylinder engines used to power Japanese navy aircraft. The 2-row radial Kasei 22 powered the Kawanishi H8K (Models 12, 22, and 32), a four-engine flying boat code-named “Emily” by the Allies. A total of 9,323 Kasei 20 series engines were built.
