wikipedia - 16 Sep 2021
The Dreadnought class is the future replacement for the Vanguard class of ballistic missile submarines.[1] Like their predecessors they will carry Trident II D-5 missiles.[6] The Vanguard submarines entered service in the United Kingdom in the 1990s with an intended service life of 25 years.[7] Their replacement is necessary if the Royal Navy is to maintain a continuous at-sea deterrent (CASD), the principle of operation behind the Trident system.[8]
