The 23×115mm round is used in Soviet (USSR)/Russian/CIS aircraft autocannon.

Although superseded by the 30×165mm round the Russian Air Force still uses it in the GSh-23L (in the aircraft's tail turrets and in the UPK-23-250 gun pod) and the GSh-6-23 (in the Su-24).

[1] The original rounds used a lower power charge of 33 g of sw 4/7 powder and achieved 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.
