The Vanguard-class nuclear attack submarines built for and operated by the Royal Navy from the late 1970s onwards.

The Vanguard-class pioneered many propulsion improvements including a natural circulation reactor plant, scoop seawater injection, the ability to cross connect main and auxiliary seawater systems, main air ejectors, and a directly coupled main engine turbine.

The Vanguard-class is comparable in capabilities to the OTL USS Narwhal (SSN-671).
