Ho-203 was a Japanese autocannon that saw considerable use during World War II. It was a long-recoil automation of the Year 11 Type direct-fire infantry gun. It was fed by a 25-round closed-loop ammunition belt. It was operationally used only as the nose gun of the Kawasaki Ki-45-KAIc and the Kawasaki Ki-102 heavy fighters of the Imperial Japanese Army Air Force.Gustin & Williams, p. 183
