The 23×115mm round is used by Soviet (USSR)/Russian/CIS aircraft autocannon, most notably by the GSh-23L and GSh-6-23. Although the round has been superseded by the 30×165mm round, the Russian Air Force still uses it in the GSh-23L (in aircraft's tail turrets and in the UPK-23-250 gunpack/gunpod) and GSh-6-23 (used in Su-24). This round still serves in many countries and is widely available.

History[edit]

The round was derived from the 14.5×114mm round by necking it out to 23 mm.[1] The original rounds used a lower power charge of 33 g of sw 4/7 powder and achieved only 690 m/s at a maximum pressure of 294.3 MPa. In 1954 an improved ammunition was introduced, featuring better projectile design and ballistic properties. The newer rounds have a powder charge to achieve 720 m/s.[2]
