HMS Valiant (S102)

The sixth, and most recent HMS "Valiant" was the second of Britain's nuclear-powered submarines, and the first of the two "Valiant" class sclass|Valiant|submarine|0. She was ordered on 31 August 1960, laid down 22 January 1962, launched on 3 December 1963 by Lady Thorneycroft, and finally entered service 18 July 1966.

She was refitted in 1970, 1977 and 1989, and participated in the Falklands War in 1982. Following the development of engine trouble in June 1994, she was paid off 12 August 1994.

Her hull and reactor are currently laid up afloat at Devonport Dockyard, Plymouth, Devon until facilities are available for the long term storage of her radioactive components.

During the HMNB Devonport Navy Days 2006, one of the members of the team currently restoring HMS|Courageous|S50|6 pointed out that HMS "Valiant" was one of the first Royal Navy submarines to have her reactor removed (hence the box-like structures that are visible in the photograph below, which penetrate deep into the pressure hull, later attempts on other vessels didn't require these structures). As the "Valiant" had been cosmetically wrecked by this work, HMS "Courageous" was selected for the museum ship to represent the SSN fleet of the Royal Navy during the Cold War. Components were removed from HMS "Valiant" to restore "Courageous". The fate of HMS "Valiant" now remains bleak.Fact|date=March 2008
