HMS Satyr was an S-class submarine of the Royal Navy, launched on 28 September 1942 by Scotts of Greenock. As part of the third batch of the S-class, she featured slight enlargements and improvements over earlier versions, designed primarily for patrols in the North Sea and Mediterranean. The vessel measured 217 feet (66.1 meters) in length, with a beam of 23 feet 9 inches (7.2 meters) and a draught of 14 feet 8 inches (4.5 meters). She displaced 842 long tons (856 metric tons) on the surface and 990 long tons (1,010 metric tons) submerged. Her crew comprised 48 officers and ratings, and she was capable of diving to depths of 300 feet (91.4 meters). Her propulsion system included two 950-brake-horsepower diesel engines for surface travel, each driving a propeller shaft, and electric motors of 650 horsepower for submerged operation. She could reach speeds of 15 knots (28 km/h) on the surface and 10 knots (19 km/h) underwater. The S-class had a substantial operational range, with 6,000 nautical miles (11,000 km) at 10 knots on the surface. Armament consisted of seven 21-inch (533 mm) torpedo tubes—six in the bow and one external in the stern—carrying a total of thirteen torpedoes, with the option to carry twelve mines instead of torpedoes. Additionally, she was equipped with a 3-inch (76 mm) deck gun, though it is uncertain if she was fitted with a 20 mm Oerlikon AA gun. During her wartime service, HMS Satyr patrolled home waters, sinking the Norwegian merchant Nordnorge and the German U-boat U-987. She also torpedoed the wreck of the German merchant Emsland off Norway. Her combat record includes unsuccessful attacks on German merchants Bochum and Emma Sauber and a convoy off Egersund. In 1944–1945, she was disarmed, streamlined, and fitted with more powerful batteries to serve as a high-speed target submarine. Post-war, she was lent to the French Navy from February 1952 to August 1961, renamed Saphir, before being broken up in April 1962 at Charlestown, Fife. HMS Satyr’s service exemplifies the versatility and wartime role of the S-class submarines in Allied naval operations.
