  • Tunguska-M1
    Air defence gun-missile system

The system is intended for protection of tank and motorized infantry units against law-altitude fixed- and rotary-wing aircrafts, variety of cruise missiles, as well as for engagement of lightly-armoured ground targets and personnel. The Tunguska-M1 combat vehicle carries two 2A38M twin-barrel AA cannons. Their overall high firing rate of 500rds./min allows effective engagement of high velocity targets staying within the gun fire reach for short periods of time.

  • Design and operation concepts

The 2A38M AA gun is an air defence modification of 30mm twin-barrel GsH-30. The main feature of the gun is an independent dual-tank water-evaporating cooling system of the barrel cluster allowing discharge of a considerable amount of ammunition in intensive firing modes. The actual muzzle velocity sensor contributes to higher accuracy of AD system firing. The percussion firing mechanism allows employment of strike-primed ammunition. An independent electro-pyrotechnical recharging system provides for quick response and reliability of the fire control systems.
