The Swiftsure class was a class of nuclear-powered fleet submarines in service with the Royal Navy from the early 1970s until 2010.

Six boats were built and commissioned. Swiftsure was decommissioned in 1992 due to damage suffered to her pressure hull during trials. Splendid followed in 2004 after defence cuts caused a reduction in the size of the Royal Navy submarine fleet. Spartan was decommissioned in January 2006, with Sovereign following on 12 September 2006. Superb was decommissioned on 26 September 2008. The remaining boat in the class, Sceptre, was decommissioned in December 2010.[2] They are being replaced by the Astute-class submarines.

A few were upgraded with the capability to launch Tomahawk cruise missiles in addition to their original armaments of torpedoes, mines and anti-ship missiles. They were also the first class of Royal Navy submarines to be built with shrouded pump-jet propulsors.[3]

SPARTAN

Decommissioned: 20 January 2006 - HMS Spartan (S105) was a nuclear-powered fleet submarine of the Royal Navy's Swiftsure class. Spartan was launched on 7 April 1978 by Lady Lygo, wife of Admiral Sir Raymond Lygo. The boat was built by Vickers Limited Shipbuilding Group (now a division of BAE Systems) at Barrow-in-Furness in Cumbria, England.
Spartan was the first boat to arrive in the Falkland Islands after the Argentine invasion of British territory in the South Atlantic. The crew began to enforce a 200 mile (370 km) maritime exclusion zone providing valuable reconnaissance to the British Task Force on Argentine aircraft movements and ensuring the Argentine Navy dare not leave port.
Unlike HMS Conqueror, Spartan did not fire in anger during the Falklands War, though she did provide valuable reconnaissance to the British Task Force on Argentine aircraft movements.
In January 1990 Spartan hit the sea bed and damaged its rudder during maneuvers off Scotland in January 1990.
In 1999, Spartan was fitted with Tomahawk cruise missiles.
The boat was decommissioned in January 2006 following a five-month global deployment covering 30,000 miles - including a goodwill port visit to Rio de Janeiro. This was the first time that a Royal Navy nuclear powered submarine had visited Brazil in 20 years.

ex-HMS Swiftsure dry-docked in Rosyth to begin preparations for final dismantling.

Swiftsure is being used as a demonstrator and will be the first UK nuclear-powered submarine to be fully dismantled by the end of 2026.

HMS Swiftsure (decommissioned 1992) now in Number 2 dry dock at Rosyth to begin the second phase of her dismantling process (removal of intermediate-level waste) to be completed in 2026.
She will be the first ex-RN nuclear submarine to be disposed of (and first in the world to be dismantled rather than whole reactor compartment removed and buried).
