HMS Revenge (S27) was the fourth of the Royal Navy's Resolution-class ballistic missile submarines. Built by Cammell Laird and launched on 15 March 1968, she was marked for disposal in 1992. She is currently being stored pending the identification of a disposal solution for all of the UK's decommissioned nuclear submarines, at Rosyth dockyard, on the northern shore of the Firth of Forth. She is docked down for maintenance and re-preservation approximately every 12 years.
