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.{{cite book | last = Koll | first = Christian | authorlink = | title = Soviet Cannon - A Comprehensive Study of Soviet Arms and Ammunition in Calibres 12.7mm to 57mm | publisher = Koll | year = 2009 | location = Austria | url = http://www.russianammo.org | doi = | isbn = 978-3-200-01445-9 | page = 181 and 195 }} 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.
