Summary
The Aichi Watch and Electric Machinery Company of Japan was established in 1899, and first built Lorraine engines for the Japanese Navy under license. In 1931 it began manufacturing its own designs in 1931, with the name Atsuta derived from its factory.
The Ha 60 Model 32 powered the World War II Japanese Aichi M6A1 Serian, Navy Special Attack Bomber, a submarine-borne float aircraft. It also powered the Yokosuka D4Y2 series Suisei Navy carrier-based dive bomber and reconnaissance aircraft (Allied Code Name Judy).
The Atsuta Model 20 and 30 series engines were the only liquid-cooled engines used operationally by the Japanese Naval Air Force. Between 1943 and 1945, the Japanese built 873 Atsuta 20 series engines. Partially enclosed in the cowling of an Aichi D4Y Suisei, the artifact is a license-built version of the German Daimler-Benz DB 601A.
