HMS Repulse was one of two Resolution-class ballistic missile submarines ordered from Vickers-Armstrongs on 8 May 1963, with a further two ordered from Cammell Laird the same day. Repulse was laid down at Vickers Armstrongs' Barrow-in-Furness shipyard on 12 March 1965 and was launched on 4 November 1967. She commissioned on 28 September 1968. She was the last of her class remaining in service with the navy, decommissioning in 1996.
Repulse was the third Polaris Missile submarine of the Resolution class to be planned; HMS Renown was the second. Due to delays with Renown's build at Cammell Laird's Birkenhead shipyard, the Barrow-in-FurnessVickers built Repulse overtook Renown and was commissioned second of class. Repulse famously ran aground on launch, much to the delight of the CND protesters and was subsequently "blacked" by the shipyard unions. She survived all of these setbacks to become the longest-serving Polaris submarine.
