3D Model

The 85 mm air defense gun M1939 (52-K) (Russian: 85-мм зенитная пушка обр. 1939 г. (52-К)) was an 85 mm (3.3 in) 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 German-Soviet 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.
