GSh-30

30-mm TWIN-BARREL AIRCRAFT CANNON

Intended for mounting on ground-attack aircrafts (Sukhoi-25, Sukhoi-39). It is a base model of a unified 30mm rapid-firing artillery weapon system.

  • High rate of fire

High firing rate (up to 3500 rds./min) is achieved due to complete time matching of basic operations of the twin-barrel system – round preparation, shockless chambering, uniform belt feed.

  • Size and weight equal to that of single-barrel systems

The use of common assemblies and actions for both barrels makes it possible to implement a rapid-fire artillery system within the dimensions and weight limits of a single barrel cannon.

  • Barrel life

The solution to barrel erosion problem is distribution of burst length between the barrels and, hence, reduction of the firing rate for each barrel.
