The M1939 37mm anti aircraft weapon system is based on the Bofors 25mm Model 1933 gun system of 1935. It saw extensive action in the Second World War for both the Soviet Army and Navy, accounting for the downing of 14,657 Axis aircraft with about 905 rounds per aircraft destroyed. Sustained fire of 60 rounds per minute can be achieved. The M1938 was also not limited to anti-air defense and could be utilized as an anti-tank gun system if need be. The single mount system has been developed into a twin-mount system and has seen limited export.
The M1938 anti-aircraft weapon system was designated as Type 55 in the Communist China inventory. It was replaced in the Soviet inventory by the ZSU-57-2 anti-aircraft gun system during the 1950's.
