The 23×152mmB [1] used by the USSR/CIS in the VYa-23 aircraft autocannon the Ilyushin Il-2 ground attack aircraft and in the 2A7 and 2A14 autocannons on the ZU-23-2 anti-aircraft gun series and ZSU-23-4 "Shilka", among others.


Note that the ammunition for the VYa-23 uses a brass case and is not functionally interchangeable with the steel-cased ammunition of the modern ZU-23 anti-aircraft gun series. These two weapons use different headspace sizes, therefore requiring ammunition of slightly different dimensions. [2] While it is no longer in use in the main anti-aircraft weapons of modern Russia, being replaced by the 30×165mm, it is still in service with the Russian Naval Infantry and many other countries.

An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber armour-piercing explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions, but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or simply "rotary cannon".
