Gryazev-Shipunov GSh-30-1
The Gryazev-Shipunov GSh-30-1 (also known by the service designation 9A-4071K) is a 30mm cannon designed for use on Soviet and later Russian military aircraft, entering service in the early 1980s. Its current manufacturer is the Russian company Izhmash JSC. Originally based on the 2A42 cannon for infantry fighting vehicle use, the GSh-30-1 is a single-barreled, gas-operated cannon weighing 46 kg (101.4 lb). Unlike many postwar cannon, it is linear action, not a revolver cannon or Gatling gun, with the Russians feeling that the reduction in rate of fire is compensated by reduced mass and bulk. The GSh-30-1 has a rate of fire of 1,800 rounds per minute, customarily limited to 1,500 rounds per minute to reduce barrel wear. Despite that, its barrel life is quite short, estimated at perhaps 2,000 rounds. The manufacturer claims its maximum effective range against aerial targets is 1,200 to 1,800 m (3,937 to 5,906 ft). In combination with a laser rangefinding/targeting system, it is reported to be extremely accurate as well as powerful, capable of destroying a target with as few as three to five rounds. The GSh-30-1 is used on the MiG-29 and multiple variants of the Su-27.
