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, a total of 9,323 engines of all models of Kasei 20 series were manufactured.

A test club is a device resembling a propeller, designed to be mounted on an aircraft engine shaft to absorb engine power during test or run-in, and usually to provide some airflow for engine cooling purposes.
