A Hotchkiss design widely used as AA MG in twin and quadruple mountings on French warships of the 1930s and 1940s.
This weapon was intended to provide close-range defense against aircraft. Like their counterparts in other nations, these small-caliber guns were incapable of defense against either torpedo-bomber or high-level bomber attacks as the bullets they fired were too light and too short ranged to be effective. Ships refitted in Allied ports had these guns replaced with 20 mm Oerlikons.
