The Gryazev-Shipunov GSh-30-2 (ГШ-30-2) or GSh-2-30 is a Soviet dual-barrel autocannon developed for use on certain ground attack military aircraft and helicopters.

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, it can also be carried in external gun pods and mounted on the Pakistani-Chinese JF-17 Thunder.{{Cite web |date=2013-04-02 |title=FC-1 (JF-17 Thunder) Multirole Fighter Aircraft - SinoDefence.com |url=http://www.sinodefence.com/airforce/fighter/fc1.asp |access-date=2023-02-09 |archive-url=https://web.archive.org/web/20130402110528/http://www.sinodefence.com/airforce/fighter/fc1.asp |archive-date=2013-04-02 }} It measures 2,044 × 222 × 195 mm, with a barrel length of 1500 mm and a weight of 105 kg.
