This class was the first all-British nuclear-powered submarine.

Rolls-Royce were responsible for building the steam-raising plant and English Electric responsible for the steam turbines.   This class would serve as the prototype for all further British-built Fleet submarines.

Their dimensions were somewhat larger than the 'Dreadnought' class.
