Valiant, was decommissioned at Devonport in 1994 due to cracks being discovered in the primary to secondary cooling system.
HMS Valiant was affectionately known as the Skimmer Killer and was ordered from Vickers at Barrow on August 31 in 1960. Launched by Mrs Peter Thorneycroft she was commissioned into Royal Navy service on July 18 in 1966 at an estimated cost of 25.3m pound.
The new boat made a promising start and in April 1967 set a record submerged passage for a British submarine on the 12 000-mile (19,312 km) homeward voyage from Singapore which took 28 days.
HMS Valiant received a number of refits, including the capability to use the Harpoon missile. HMS Valiant took part in the Falklands War.
