The Aichi AE1A Atsuta (Japanese: アツタ or 熱田) was a Japanese licensed version of the German Daimler-Benz DB 601A 12-cylinder liquid-cooled inverted-vee[1] aircraft engine. The Atsuta powered only two models of Imperial Japanese Navy Air Service (IJNAS) aircraft in World War II. The Imperial Japanese Army Air Service (IJAAS) used the same engine (manufactured by Kawasaki as the Kawasaki Ha40) to power its Kawasaki Ki-61 Hien (Allied reporting name[2] "Tony") fighter. The IJNAS's Atsuta and its IJAAS cousin, the Ha-40 were based on the engine that powered Germany's Messerschmitt Bf 109E fighter.[3]
