The 76 mm air defense gun M1931 (Russian: 76-мм зенитная пушка обр. 1931 г.) was a anti-aircraft gun used by the Soviet Union during the Winter War and the first stages of World War II.

History[]

The configuration of the air defense gun M1931 owed much to the design of the contemporary Vickers 3-inch anti-aircraft guns. The Soviet M1931 like the Vickers gun had a two-wheeled carriage with collapsible cruciform outriggers.[1]

The M1931 was replaced in production in 1938 by the 76 mm air defense gun M1938 which had a four-wheeled dual-axle carriage with two collapsible outriggers. The M1931 and M1938 had nearly identical performance and were gradually replaced by the more powerful 85 mm air defense gun M1939.[1] A number of M1931 guns were captured by Finland during the Winter War and were employed by them as the 76 ItK/31 ss during World War II.[3] Likewise, M1931 guns captured by the Germans were given the designation 7.62 cm Flak M.31(r) and used until they were either worn out or their ammunition supply ran out. A few were rebored to fire German 8.8 cm ammunition and redesignated the 7.62/8.8 cm Flak M.31(r). However, the majority were scrapped in 1944.[1]
