57 mm AZP S-60

The S-60 is a Soviet anti-aircraft artillery system that uses 57 mm caliber AZP-57 anti-aircraft guns (developed in the mid-1940s) and is widely used around the world.

The design of the 57 mm automatic anti-aircraft gun began in 1944 at NDI-58 of TsAKB Vasily Grabin under the leadership of Lev Loktev based on the theoretical developments of Mikhail Loginov. The new model was intended to replace the existing 37 mm anti-aircraft guns M1939. The experimental sample of the AZP-57 gun was tested at the Donguz test site at the end of 1946, and defects were eliminated. The gun was adopted by the Soviet Army in January 1950 under the name “57-mm anti-aircraft automatic gun AZP-57”. In the same year, its serial production began at Plant No. 4 named after Voroshilov in Krasnoyarsk.

The AZP-57 of the S-60 system became the first Soviet field anti-aircraft gun, the aiming of which was carried out remotely. It is mounted on a four-wheel chassis, which allows it to be towed by a military truck (6x6) or a tracked artillery tractor. It takes 1 minute for the crew to convert the gun from traveling to combat position, and 2 minutes to do the opposite.
