Since April 1969 the Royal Navy has always had one ballistic missile submarine on patrol at any one time. This is known as continuous-at-sea deterrent (CASD) and was originally provided by the submarine-based Polaris system. The Royal Navy formally assumed responsibility for the UK’s strategic nuclear deterrent in June 1969 from the RAF’s V-force. The deterrent has been solely submarine-based since the late 1990s. At 50 years, it is also the longest ongoing operation ever delivered by the Ministry of Defence.
Marking the 50th anniversary of Continous At Sea Deterrent with special CASD 50 postmarks - 3rd May 2019 for National Service of thanksgiving Westminster Abbey, and 5th July 2019 - Naval Parade HMNB Clyde Helensburgh.
50th Anniversary Continous At Sea Deterrent
CASD is now provided by the four Vanguard-class submarines carrying the Trident missile system: HMS Vanguard, HMS Victorious, HMS Vigilant and HMS Vengeance (the boats were given names formerly associated with battleships and aircraft carriers). They were designed and built at Barrow-in-Furness by Vickers Shipbuilding and Engineering, now BAE Systems Submarine Solutions, the only shipbuilder in the UK with the facilities and expertise to build nuclear submarines, with the Devonshire Dock Hall built specially for the purpose.
In 2016 the House of Commons approved a decision to maintain the UK’s nuclear deterrent beyond 2030. The Vanguard-class submarines will be replaced by the new Dreadnought-class. The first is expected to enter service in the early 2030s and have a service life of at least 30 years.
