The Gryazev-Shipunov GSh-30-2 (ГШ-30-2) or GSh-2-30 is a powerful twin-barrel autocannon used on certain Russian military aircraft.

The cannon is not related to the Gryazev-Shipunov GSh-30-1, but is a heavy-duty gas-operated weapon operating on the Gast principle like the Gryazev-Shipunov GSh-23L. Rate of fire is about 3,000 rounds per minute. The weapon is designed to be rugged and resistant to dirt; this makes it relatively heavy. Depleted uranium enhanced armor-piercing shells suitable for the GSh-30-2 are operationally qualified.

The GSh-30-2 is carried by the Sukhoi Su-25 ground attack plane and in external gun pods. It measures 2044 x 222 x 195 mm, with a barrel length of 1500 mm and a weight of 115 kg. The GSh-30K is a modified version with 2400 mm long water-cooled barrels, a variable rate of fire, and dimensions of 2944 x 222 x 195 mm. It is used on a fixed mounting on late model Mi-24 helicopters, e.g the Mi-24P.
