Introduction
The GSh-301 is a modern Soviet single barrel autocannon with a high rate of fire. It arms the two most common types of Soviet multirole fighters, the MiG-29 and the larger Su-27.
Design
The GSh-301 was developed to be very light and have a high rate of fire. This was achieved by using the short recoil mechanism. In the West modern aircraft cannon are usually revolver or gatling type weapons.
Firepower
The GSh-301 fires the 30x165mm round at a rate of fire of 1.500 to 1.800 rpm. Short bursts are fired. A 100 round burst destroys the barrel. Effective range is quoted as 200 to 800 m against aerial targets and 1.200 to 1.800 m against ground targets. Combined with targeting computer and laser range finder accuracy is reported to be good.
Platforms
The GSh-301 arms the two most common types of Soviet multirole fighters, the MiG-29 and Su-27. It is also used in the various Su-27 derivatives, including the Su-30, Su-33, Su-34 and Su-35. A gun pod was designed around the GSh-301 but was produced only in very limited numbers.
