Pribor's public history starts with the November 1941 establishment of Plant No. 398 in Moscow to produce fuzes and assemble ammunition during the Second World War. Rostec says the plant began supplying the Red Army the following month and later changed names through KB-398, GSKB-398, NIIP, NPO Pribor, and Federal Scientific Production Center Pribor before the present JSC NPO Pribor named after S.S. Golembiovsky identity.
The manufacturer's continuing role is centered on artillery and grenade-launcher ammunition rather than complete vehicle or missile platforms. Rostec states that Pribor produces and supplies 23 mm and 30 mm barrel-artillery ammunition for Russian forces and export, plus 30 mm and 40 mm grenade-launcher rounds. Archived Pribor product pages list 23 mm and 30 mm aviation cartridges, while defense-industry sanctions material identifies 30 mm and 40 mm grenade-launcher rounds and the 6S19 Balkan automatic grenade-launcher complex as part of the company's product context.

Open sources use several Pribor names across Soviet, FSUE, and joint-stock periods. FSUE GNPP Pribor appears in older manufacturer attribution, while current sanctions and corporate references generally identify the successor legal entity as JSC NPO Pribor named after S.S. Golembiovsky. Short aliases such as NPO Pribor were not added because they are broader labels that can collide with Tecmash holding context.
