Service
Swiftsure became famous for her mission to acquire the acoustic signature of the Soviet aircraft carrier Kiev. Upon locating a new unique acoustic sound that indicated the Kiev's presence, hid underneath her for several hours, with her raised periscope just 10 feet (3.0 m) under the aircraft carrier's hull, allowing the crew of Swiftsure to take photographs and record the aircraft carrier's acoustic signature.[3] This was documented in 2013 as part of the BBC's Cold War season.[4]
Swiftsure arrived in HMNB Devonport in January 1979 for her first scheduled refit. However, due to an industrial dispute[5] the refit did not begin until April 1980, 15 months after the boat arrived into Devonport. Despite a statement in the House of Commons in mid-November 1981 that the refit would be completed by mid-1982[6] Swiftsure's refit was eventually completed in March 1983, at a total cost of £85 million.[7]
Swiftsure was due to enter a second refit in 1992, but instead she was decommissioned that year. The reason for the premature decommissioning is often cited as pressure hull damage suffered during sea trials although that is now thought to be incorrect; it is believed the reason for the boat's premature decommissioning was due to the finding of cracks in her reactor during a refit. Her nuclear core was safely removed in June 1992.
Since 1992, she has been stored afloat in the non-tidal basin at
