Soviet conventional ammunition production was organized through a state industrial system rather than through ordinary commercial manufacturers. A CIA overview of the Soviet weapons industry described roughly 50 major design bureaus and about 150 major production complexes across the USSR, with additional suppliers supporting design, materials, and assembly work.
The international part of this production base is especially visible in 122 mm ammunition. Public references for the 9M22U / M-21OF Grad rocket identify Soviet production and licensed production in Bulgaria, Romania, and Czechoslovakia, while current company pages from MSM Group and ROMARM show continued production of Soviet-pattern 122 mm artillery ammunition for D-30 and 2S1-class systems.

This is a distributed historical and international production category, not a single incorporated company. No unified official website, headquarters, or map location exists for the combined Soviet and international producer set, so the website field points to a stable CIA Reading Room reference and headquarters fields are intentionally omitted.
