85mm Anti-Aircraft Gun 52-K

Soviet 85mm anti-aircraft gun (1939), used in anti-tank role too, outdoor exhibit St. Petersburg.

The Soviet 85mm anti-aircraft gun M1939 (52-K) was the Red Army's heavy AA weapon in World War II, capable of engaging targets at altitudes up to 10 kilometres. Like Germany's 88mm Flak, it was also used in an anti-tank role with devastating effect. The gun's 85mm calibre directly inspired the tank gun later fitted to the T-34/85. The St. Petersburg exhibit illustrates the robust pragmatism of Soviet wartime artillery design.
