23×152mm
The 23×152mmB is a large-caliber cartridge 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.
