Swiftsure (S 126)

Class: 1973 - 2010: Swiftsure Class
Built By: Vickers (Barrow)
Build Group: SSN 4
Fate:
Cracks were found in the reactor in 1992 and was decommissioned the same year.

Swiftsure is currently in dry dock at Rosyth, in Scotland, where it is being carefully dismantled.

An estimated 90% of her total weight will be repurposed, with some of the high-quality steel used to create components for future Royal Navy submarines.

Swiftsure is set to be first of the UK's decommissioned nuclear submarines to be fully dismantled by the end of 2026.
Featured Film
Black Sea
From Director Kevin Macdonald (The Last King Of Scotland) comes this gripping thriller about a rogue submarine captain, played by Jude Law (Sherlock Holmes, The Talented My Ripley) who pulls together a misfit crew to search for sunken treasure in the Black Sea.

As greed and desperation take control, the increasing uncertainty of the mission causes the men to turn on each other to fight for their own survival.
