HMS Courageous (S50) was a Churchill-class nuclear fleet submarine in service with the Royal Navy from 1971. In 1982, the Courageous was sent with her sister ship, HMS Conqueror, with the British task force to retake the Falkland Islands from the occupying Argentine forces. She returned home later in the year without damage. The Courageous was retired from service in 1992. She is now a museum ship at Devonport Dockyard. (wikipedia)
