La clase Astute es la familia de submarinos de ataque de propulsión nuclear de la Royal Navy construida por BAE Systems en Barrow-in-Furness. Sus unidades usan mástiles de sistema de combate en lugar de periscopios ópticos tradicionales, llevan misiles de ataque terrestre Tomahawk y torpedos pesados Spearfish, y proporcionan capacidad encubierta de ataque, vigilancia y guerra antisubmarina.

Vanguard-class submarine, Nuclear-powered ballistic missile submarine, Naval SystemsNaval SystemsVanguard-class submarineNuclear-powered ballistic missile submarineThe Vanguard-class submarine is the Royal Navy's four-boat nuclear-powered ballistic missile submarine class for the United Kingdom's continuous at-sea nuclear deterrent. Built at Barrow-in-Furness by Vickers Shipbuilding and Engineering, the class carries Trident II D5 missiles, remains in service as the UK's single nuclear delivery platform, and is being sustained until Dreadnought-class submarines replace it in the 2030s.
Upholder/Victoria-class submarine, Diesel-electric patrol submarine, Naval SystemsNaval SystemsUpholder/Victoria-class submarineDiesel-electric patrol submarineThe Upholder/Victoria class is a four-boat Type 2400 diesel-electric submarine line designed in the United Kingdom as the Royal Navy's late-Cold-War successor to the Oberon class. The Vickers Shipbuilding and Engineering design was ordered for HMS Upholder in 1983, followed by three Cammell Laird-built boats, but the Royal Navy withdrew the class in 1994 as it moved to an all-nuclear submarine force. Canada acquired the reserve boats in 1998, renamed them as the Victoria class, and rebuilt them around Canadian fire-control, communications, and Mk 48 heavyweight-torpedo requirements. Current Royal Canadian Navy and National Defence material frames the class as Canada's covert underwater-surveillance and deterrence force while Victoria Class Modernization keeps the boats in service into the mid-to-late 2030s.

The class carries a D-9RM missile system with 16 R-29RM-family SLBMs, four 533 mm torpedo tubes, and modernized Sineva/Layner-era missiles; public sources distinguish the seven boats built from smaller operational counts as individual hulls cycle through overhaul or replacement by Borei-class SSBNs.
