The cannon is not related to the Gryazev-Shipunov GSh-30-1, but is a recoil-operated cannon using the Gast principle, like the Gryazev-Shipunov GSh-23L.

The GSh-30-2 was designed for the Sukhoi Su-25 ground attack plane and can also be carried in external gun pods. It measures 2,044 × 222 × 195 mm, with a barrel length of 1500 mm and a weight of 105 kg. The GSh-30K is a modified version with 2400 mm long water-cooled barrels, a variable rate of fire, and dimensions of 2,944 × 222 × 195 mm. It is used on a fixed mounting on late model Mil Mi-24 helicopters, e.g. the Mi-24P.
