The Hotchkiss 25 mm anti-aircraft gun was an anti-aircraft autocannon designed by the French firm of Hotchkiss. It served in World War II with French, Japanese and other nations' forces. Other than the designer company and the calibre, this weapon is not related to the semi-automatic 25 mm Hotchkiss anti-tank gun; in particular, the cartridge used is different.
