HMS Churchill was the first of three Churchill-class submarine nuclear fleet submarines that served with the Royal Navy.
Construction
Churchill, the Royal Navy's fourth nuclear-powered fleet submarine was ordered on 21 October 1965, and was laid down at Vickers Shipbuilding and Engineering Limited (VSEL)'s Barrow-in-Furness shipyard on 30 June 1967. The submarine was launched by Mary Soames, Winston Churchill's youngest daughter, on 20 December 1968 and commissioned on 15 July 1971.[1][2]
Propulsion
Churchill was chosen to trial the first full-size submarine pump jet propulsion. Trials of a high-speed unit were followed by further trials with a low-speed unit, and these were successful enough for the same propulsion to be fitted in the rest of the class.[3] Later British submarine classes also featured the pump jet, although first-of-class vessels Swiftsure and Trafalgar were fitted with propellers at build.
