The Motorised Submersible Canoe (MSC), nicknamed Sleeping Beauty, was an underwater vehicle built by the British Special Operations Executive (SOE) during the Second World War. It was designed to enable a single frogman to sabotage enemy ships, though it would also be used for short-range reconnaissance. They were replaced by the diver propulsion vehicle after the end of the war.
