Quick Facts Type, Place of origin ...

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.
