During the Soviet period, naval construction was assigned across named shipyards such as Zhdanov, Yantar, Zaliv, Vympel, and other yards according to program size, geography, capacity, and export demand. A single ship class could therefore have hulls from several yards while retaining a common project number, design bureau lineage, and Soviet or Russian naval designation.
In the Russian Federation, much of the public naval-industrial structure is now grouped around United Shipbuilding Corporation, a state-owned holding established in 2007. USC describes itself as Russia's largest shipbuilding company and says its network includes more than 60 shipyards, design offices, ship-repair yards, and related enterprises; U.S. State Department designation material also identifies USC and subsidiaries as responsible for Russian Navy warship development, construction, repair, and design.

This is a broad Soviet/Russian naval shipbuilding production grouping, not a single incorporated firm. Public sources are strongest when a specific class identifies several yards or when modern sources discuss United Shipbuilding Corporation and its subsidiaries; when a reliable source identifies a narrower yard, that yard should be treated as the specific manufacturer for that system.
