The Admiralty industrial site traces its official history to a shipyard founded under Peter the Great on 5 November 1704. By the twentieth century the Saint Petersburg yard was associated with submarines, cruisers, naval auxiliaries, ice-capable vessels, deep-sea craft, and specialized underwater technology rather than a single design bureau.
Federation of American Scientists background material describes the 1972 absorption of the Leningrad Shipbuilding and Mechanical Engineering Sudomekh yard into Admiralty and says the resulting organization was named the Leningrad Admiralty Association. That structure matters for older source attributions because Soviet and early post-Soviet reporting may use Admiralty, Sudomekh, Leningrad Admiralty Association, or United Admiralty Sudomekh labels for related St. Petersburg submarine work.

United Admiralty Shipyard is retained as a canonical manufacturer label for records whose sources use United Admiralty or United Admiralty Sudomekh wording. The separate Admiralty Shipyards profile owns the modern company name and overlapping legacy aliases, so those labels are not duplicated here.
