Sevmash is the Severodvinsk shipyard and production association that forms Russia's central nuclear-submarine construction base. The enterprise is part of United Shipbuilding Corporation, works from Arkhangelskoye Highway in Severodvinsk, and publicly describes state-defense orders, nuclear submarines, ship repair, modernization, and Arctic marine engineering as core activities.
9 weaponsSevmash traces its official production history to 21 December 1939, when Shipyard No. 402 laid down the battleship Sovetskaya Belorussiya. The plant later shifted from wartime surface-ship and repair work into diesel-electric and nuclear submarine construction, including Project 627, Project 667, Project 949/949A, Project 941, Project 971, Borei, Borei-A, Yasen, and Yasen-M boats.
The shipyard's own public materials describe Sevmash as one of Russia's largest shipbuilding complexes and state that, after the Soviet collapse, it effectively remained the only enterprise in Russia and the post-Soviet space performing the full construction and testing cycle for submarines with nuclear power plants. In addition to naval work, Sevmash lists offshore oil-and-gas platforms, technical industrial products, ship repair, modernization, disposal, and marine engineering among its activities.
Fourth-generation Russian ballistic-missile submarine families that Sevmash says are currently built at the Severodvinsk yard, with service support also assigned to the enterprise.
