Project history: At the 1962 Nassau Conference, the momentous decision was taken to transfer responsibility for the United Kingdom's nuclear deterrent from the RAF to the RN, following the cancellation of the airborne Skybolt system. Instead the RN was to build five nuclear ballistic missile sub-names (SSBNs) based broadly on the missile compartment of the US Navy's Lafayette class, with British equipment and machinery, but armed with missiles, tubes and fire control systems supplied from the United States.
A special Polaris Executive was set up to supervise the building of the boats and the creation of training and support facilities, and so successful was the collaboration between the administrative and technical sides that the first boat, Resolution, went on patrol as planned in 1968. With Dreadnought it was the only British post-1945 defence programme to remain within its financial budget. Only one problem was encountered: the figure of five boats was arrived at after a careful study of refit schedules, and when the new Labour Defence Minister, Denis Healey, cancelled the order for the fifth boat (named Ramillies) as a gesture of appeasement, it became difficult to guarantee that one Polaris 'bomber' would remain on patrol at all times. Up to 1992, however, there had officially been no gap in the patrol.
Apart from the use of British equipment and design features from the Valiant class, the main departure from the Lafayette class was the rejection of diving planes on the fin. Although these are standard in USN submarines, British designers maintain that their advantages of better slow-speed control do not outweigh their disadvantages.
