The 85 mm air defense gun M1939 52-K (85-мм зенитная пушка обр. 1939 г. 52-К) was an 85 mm Soviet anti-aircraft gun, developed under guidance of leading Soviet designers M. N. Loginov and G. D. Dorokhin.
This gun was successfully used throughout the Second World War against level bombers and other high- and medium-altitude targets. In emergencies they were utilized as powerful anti-tank weapons.
The barrel of the 52-K was the basis for the family of 85-mm Soviet tank guns. After the war some 52-Ks were refitted for peaceful purposes as anti-avalanche guns in mountainous terrain.
