Description

The M1939 (61-K) is a Russian-made 37mm anti-aircraft gun which was developed during the late 1930s and used during the Second World War. The 61-K was accepted for service in Russian army in 1939 under the designation of the 37 mm Automatic Anti-aircraft Cannon M1939 and the first order placed for 900 units. It is believed that total production amounted to almost 20,000 weapons with final deliveries made in 1945. The M-1939 is operated by a crew of eight soldiers. The effectiveness of the 37-mm automatic anti-aircraft gun M1939 against modern aircraft is very limited and it has no poor weather or all-weather capability. The M1939 is not limited for anti-air defense but could be also used as anti-tank gun system. The M1939 is no longer in service with the Russian armed but many countries in Middle East and Africa still use this type of anti-aircraft gun.
