What Joint Stock Company does

Sevmash (AO PO Sevmash / Акционерное общество «Производственное объединение «Северное машиностроительное предприятие») is Russia's largest shipbuilding complex and the sole Russian enterprise constructing fourth-generation nuclear-powered submarines for the Russian Navy. Founded in 1939 in Severodvinsk, Arkhangelsk Oblast, the enterprise spans more than 320 hectares and is wholly owned by United Shipbuilding Corporation (OSK), a Russian state defense holding company. Across four generations of nuclear submarine programs, Sevmash has built more than 142 nuclear-powered submarines, including the first Soviet nuclear submarine K-3 'Leninsky Komsomol' (1958), the Project 941 Typhoon-class (the largest submarines ever built at 49,800 tons underwater displacement), the world's fastest nuclear submarine Project 661 (44.7 knots), and the deepest-diving Project 685 (1,027 m).

The current product portfolio centers on three active fourth-generation programs: Project 955 Borei-class strategic missile submarines armed with the Bulava ICBM complex, Project 885M Yasen-M multi-role nuclear cruise-missile submarines with eight VLS modules capable of carrying Kalibr, Oniks, and Zircon missiles, and Project 1144.2M heavy nuclear-powered missile cruisers (Admiral Nakhimov modernization). A specialized new platform, the Khabarovsk, is being built to carry the Poseidon nuclear drone. The company operates as a state-owned cost-plus defense contractor: revenue is not publicly disclosed, pricing is set through Russian state defense procurement (gosudarstvennyy zakaz), and the sole end-customer is the Russian Ministry of Defense, with vessels delivered directly to the Northern and Pacific Fleets upon completion of sea trials. Current General Director is Mikhail Anatolyevich Budnichenko.

Direct peers

• Naval Group: France's national naval shipbuilder and builder of Barracuda/Suffren-class SSNs and the future SNLE 3G SSBN. Directly comparable as a state-supported nuclear submarine shipyard serving a single national navy customer.
• ASC Pty Ltd (Australian Submarine Corporation): Australian submarine builder (Collins-class, future AUKUS SSN program). Comparable as a national submarine shipyard serving a single navy customer, with similar long-cycle, government-funded business model.
• General Dynamics Electric Boat: Sole U.S. builder of nuclear-powered submarines (Virginia- and Columbia-class SSNs/SSBNs) for the U.S. Navy. Most direct global peer to Sevmash in terms of nuclear submarine construction capability, customer concentration (single national navy), and project scale.
• Daewoo Shipbuilding & Marine Engineering (Hanwha Ocean): South Korean submarine builder delivering KSS-III Batch II/III (Dosan Ahn Changho-class) SSBs for the Republic of Korea Navy. Comparable as a non-nuclear submarine constructor with single-customer focus, but operating in a different geopolitical context.
• BAE Systems Submarines: UK-based builder of Astute-class SSNs and Dreadnought-class SSBNs for the Royal Navy. Comparable in that it is a single-country, single-customer nuclear submarine manufacturer with similar long-cycle, government-funded production.
• Mitsubishi Heavy Industries (Submarine Operations, Kobe): Japan's submarine builder producing Soryu/Taigei-class submarines for the Japan Maritime Self-Defense Force. Comparable in single-customer, domestic-only submarine construction model, though nuclear capability is limited.
• Admiralty Shipyards (Admiralteyskie Verfi): Other Russian shipyard under United Shipbuilding Corporation that builds non-nuclear submarines (Kilo/Varshavyanka-class). Domestic peer sharing the same Russian state customer; Sevmash differentiates via nuclear-propulsion capability.
• ThyssenKrupp Marine Systems (TKMS): German submarine shipbuilder producing Type 212/214 and forthcoming Type 326 submarines. Comparable as a specialist submarine builder, though primarily diesel-electric/AIP rather than nuclear, with a broader export customer base.

Broad incumbents

• Huntington Ingalls Industries: Largest U.S. military shipbuilder (carrier, surface combatant, and amphibious programs) and parent of Newport News Shipbuilding (Columbia-class SSBN modules). Broader incumbent in naval shipbuilding; competes in adjacent rather than direct submarine-construction roles.
• United Shipbuilding Corporation (OSK): Sevmash's parent conglomerate consolidating most Russian shipbuilding assets. Broad incumbent comparable in product portfolio scope (surface combatants, civilian vessels) but Sevmash operates as the nuclear-submarine flagship within the group.
