Admiralty Shipyards

Admiralty Shipyards is a Saint Petersburg shipyard and United Shipbuilding Corporation subsidiary whose modern defense work centers on diesel-electric submarines, special-purpose underwater craft, naval auxiliaries, and Arctic patrol ships. The yard traces its institutional history to 1704, operates from the Fontanka Embankment complex, and remains one of Russia's principal conventional-submarine production sites.

The shipyard's public history links the Admiralty complex to more than three centuries of Russian naval and civil shipbuilding. Its twentieth-century and post-Soviet record includes Project 877EKM export submarines, Project 636 Kilo-family submarines, deep-diving and special-purpose underwater vehicles, missile range instrumentation ships, and specialized ice-capable vessels.

For catalog purposes, Admiralty Shipyards connects several Russian naval records that share the same production yard rather than a single design bureau. Rubin-designed Project 636 and Project 677 submarines, Almaz-designed Project 23550 patrol icebreakers, and specialized Soviet-era auxiliary ships show the yard's role as a production plant within a larger Russian naval-industrial system.

Lada-class submarine, Diesel-electric attack submarine, Naval Systems2015 Various ConflictsLada-class submarineDiesel-electric attack submarineBuilt in: RussiaThe Lada-class submarine is Russia's Project 677 diesel-electric attack submarine family, designed by Rubin and built by Admiralty Shipyards as a low-signature conventional boat for coastal, confined-water, and blue-water tasks. The class combines six 533 mm tubes with torpedo-missile armament, automated control, improved sonar, and optional air-independent-propulsion provisions; Russian sources reported a return to serial service with Kronstadt in 2024 and Velikiye Luki in 2025 after the troubled Sankt Peterburg prototype.

The family keeps six 533 mm bow tubes for torpedoes, mines, and tube-launched cruise missiles, while later 636.3 boats add Kalibr-PL strike capability and updated sensor, navigation, and combat-management equipment.

Centered on Bandar Abbas and the Strait of Hormuz, the fleet supports coastal sea denial, mine warfare, and anti-ship strike; during Operation Epic Fury, CENTCOM listed Iranian Navy ships and submarines among vessels damaged or destroyed.

Open sources describe two boats, AS-21 and AS-35, as improved follow-ons to the Project 1851 X-Ray/Nelma design, built at the Leningrad/Admiralty yard for carrier-borne deep-sea missions, diver-support work, and GUGI-linked seabed operations; published dimensions vary widely because the class remains highly opaque.
