Gryazev-Shipunov GSh-30-2 (Russian: Грязев-Шипунов ГШ-30-2), a Soviet twin-barreled 30 mm autocannon; ... a Soviet 7.62 mm quad-barreled rotary machine ...
The Bangerter machine gun uses a blow-forward operation and is the most complex example. The Slostin machine gun uses a similar operation but with gas pistons on each barrels. The GShG-7.62 machine gun and GSh-6-23, both use a more effective, simpler gas piston drive in the center of the barrel cluster.
There are also several gun pods available for mounting on external hardpoints: UPK-23 for air-to-air use, with one or two fixed GSh-23 guns and 200–400 rounds of ammunition, and SPPU-22 pods with traversable barrels for strafing, from 0° to −30° and carried 280 rounds of ammunition in each (they were most often carried by the Su-17/-20 ...
The hammer itself is a metal piece that forcefully rotates about a pivot point. [2] The term tumbler can refer to a part of the hammer or a part mechanically attached to the pivot-point of the hammer, depending on the particular firearm under discussion (see half-cock). According to one source the term tumbler is synonymous with hammer. [3] [4]
This makes the weapon advantageous in dogfights, where pilots often have a very small window for engaging the enemy. Ignition is electrical, as with the smaller GSh-6-23. On the MiG-27 "Flogger" the GSh-6-30 had to be mounted obliquely to absorb recoil. The gun was noted for its high (often uncomfortable) vibration and extreme noise.
The GSh-30-1 is a single-barreled, recoil operated autocannon weighing 46 kg (101 lb). Unlike many postwar cannons, it uses a short recoil action instead of a revolver cannon or Gatling gun mechanism.
Short range: the maximum effective range of gun systems is about 5,000 metres (16,000 ft); systems with lighter projectiles have even shorter range. The expected real-world kill-distance of an incoming anti-ship missile is about 500 m (1,600 ft) or less, [ 4 ] still close enough to cause damage to the ship's sensor or communication arrays, or ...
GSh-6-23M has the highest rate of fire out of any autocannon so far. [6] The GSh-6-23 is used by the Sukhoi Su-24 attack aircraft, the MiG-31 interceptor aircraft, and the now-obsolete Sukhoi Su-15 among others. However, after two Su-24s were lost because of premature shell detonation in 1983, and because of some other problems with gun usage ...
