The Gryazev-Shipunov GSh-6-23 (Russian: Грязев-Шипунов ГШ-6-23) (GRAU designation: 9A-620 for GSh-6-23, 9A-768 for GSh-6-23M modernized variant) is a six-barreled 23 mm rotary cannon used by some modern Soviet/Russian military aircraft.[4]

The GSh-6-23 differs from most American multi-barreled aircraft cannon in that it is gas-operated, rather than externally powered via an electric, hydraulic, or pneumatic system.

The GSh-6-23 uses the 23x115 Russian AM-23 round, fed via linked cartridge belt or a linkless feed system.[5] The linkless system, adopted after numerous problems and failures with the belt feed, is limited.[6][better source needed] Fire control is electrical, using a 27 V DC system. The cannon has 10 pyrotechnic cocking charges, similar to those used in European gas-operated revolver cannons such as the DEFA 554 or Mauser BK-27.

The rapid rate of fire exhausts ammunition quickly: the Mikoyan MiG-31 aircraft, for example, with 260 rounds of ammunition (800 rounds maximum), would empty its magazine in less than two seconds.

The GSh-6-23 is used by the Sukhoi Su-24 attack aircraft, the MiG-31 interceptor aircraft, and the now-obsolete Sukhoi Su-15 among others.

It is also used in the SPPU-6 gun pod, which can traverse to -45° elevation, and +-45° azimuth.[7]
