HMS Vengeance is the fourth and final Vanguard-class submarine of the . Vengeance carries the Trident ballistic missile, the UK's nuclear deterrent.[] Vengeance was built at Barrow-in-Furness by Vickers Shipbuilding and Engineering Ltd (now BAE Systems Submarine Solutions), was launched in September 1998, and commissioned in November 1999. Before she was commissioned, the British Government stated that once the Vanguard became fully operational, they would only carry 200 warheads. Vengeance carries the unopened "last instructions" () of the current British Prime Minister that are to be used in the event of a national catastrophe or a nuclear strike.[3]

Operational history On 31 March 2011, while on a training exercise Vengeance suffered a blockage in her propulsor causing a reduction in propulsion. The boat returned to Faslane naval base on the surface under her own power. According to the MOD the problems were not nuclear related.[][4] Vengeance is currently (as of 2012) undergoing a three-and-a-half year refit at HMNB Devonport near Plymouth while her sister ship Vigilant is taking her place[5]
