HMS Sportsman was a third-batch S-class submarine constructed for the Royal Navy during World War II. Laid down on 1 July 1941 at Chatham Dockyard, she was launched on 17 April 1942 and commissioned on 21 December 1942. The vessel measured 217 feet (66.1 meters) in overall length, with a beam of 23 feet 9 inches (7.2 meters) and a draught of 14 feet 8 inches (4.5 meters). Displacing 865 long tons (879 tonnes) on the surface and 990 long tons (1,010 tonnes) submerged, the submarine had a crew complement of 48 officers and ratings and a maximum diving depth of 300 feet (91.4 meters). Powered by two 950-horsepower diesel engines for surface travel and two 650-horsepower electric motors for submerged operations, Sportsman could reach speeds of 15 knots on the surface and 10 knots underwater. Her operational range was 6,000 nautical miles at 10 knots on the surface, with a submerged range of 120 nautical miles at 3 knots. Armed with seven 21-inch (533 mm) torpedo tubes—six in the bow and one in the stern—she carried thirteen torpedoes, with the option to carry twelve mines instead. Additionally, she was equipped with a 3-inch (76 mm) deck gun. During her wartime service, Sportsman primarily operated in the Mediterranean and Aegean Seas. She conducted multiple patrols, sinking a variety of Axis vessels, including the French passenger ship Général Bonaparte, which she sank on 19 May 1943, resulting in the loss of 137 survivors. Notably, she also sank the German transport SS Petrella in February 1944, despite it being marked as a POW ship, killing approximately 2,670 prisoners. The vessel was heavily damaged in September 1943 after a mistaken attack by an Allied bomber, which destroyed her bridge and caused serious damage. After repairs, she returned to active patrols, engaging German and Greek vessels, and supporting special operations. Post-war, Sportsman underwent a refit in the United States before returning to the UK. She was scheduled for operations in the Far East, but the end of the war canceled these plans. In July 1952, she was transferred to the French Navy and renamed Sibylle. Her service was brief; she was lost with all hands off Toulon on 24 September 1952 during anti-submarine exercises, after which a large oil patch was found in the area. Her wreck lies in deep waters, and her loss marked the end of her distinguished wartime career. Throughout her service with the Royal Navy, Sportsman sank 12 Axis ships totaling over 20,242 GRT.
