Built by Vickers Armstrong at a cost of £40.2m. Ordered in May 1963, she was laided down on February 26 1964 by the Director General Ships, Sir Alfred Sims. The launch on September 15 1966 was attended by Queen Elizabeth, the Queen Mother. She was commissioned on October 2 1967 and following extensive trials, including the firing of her first Polaris missile on February 15 1968, commenced her first patrol on June 15 1968.
Her Polaris system was updated in 1984 with the Chevaline warheads, but not Poseidon. Resolution conducted the longest Polaris patrol of 108 days in 1991.
Following the completion of the first Trident submarine in 1992, the Resolution class were gradually removed from service. Resolution was de-commissioned on October 22 1994 after 69 patrols and laid up at the Rosyth Dockyard.
