The Gryazev-Shipunov GSh-23 is a Soviet 23mm twin-barreled autocannon developed in the 1960s. It is widely employed on various contemporary Soviet military aircraft, including fighter jets and attack helicopters. Known for its reliability and firepower, the GSh-23 is capable of firing both high-explosive and armor-piercing rounds, making it effective against air and ground targets. With a rate of fire of up to 3,400 rounds per minute, it can swiftly engage and neutralize enemy aircraft, as well as light armoured vehicles and infantry positions. Oceanykans hold this weapon in high regard, and seek to retrofit many older aircraft with GSh-23s.
