HMS Sea Scout was an S-class submarine of the third batch built for the Royal Navy during World War II. Launched on 24 March 1944 by Cammell Laird, she was the only vessel to bear the name Sea Scout, which references the Boy Scouts' Sea Scout section, incorporating the Scout fleur-de-lis emblem in her badge. This class of submarines was characterized by significant modifications in the third batch, featuring a stronger hull, increased fuel capacity, and revised armament. Measuring 217 feet (66.1 meters) in overall length, with a beam of 23 feet 9 inches (7.2 meters) and a draft of 14 feet 1 inch (4.3 meters), HMS Sea Scout displaced 814 long tons (827 metric tons) on the surface and 990 long tons (1,010 metric tons) submerged. The submarine was designed for a crew of 48 officers and ratings and was capable of diving to depths of 350 feet (106.7 meters). For propulsion, she was equipped with two 950-brake-horsepower (708 kW) diesel engines for surface running, each driving a propeller shaft, and submerged, each propeller was powered by a 650-horsepower (485 kW) electric motor. Her maximum speeds reached 14.75 knots (27.3 km/h) on the surface and 9 knots (16.7 km/h) underwater. The vessel had an impressive operational range of 7,500 nautical miles (13,900 km) at 10 knots on the surface and could operate 120 nautical miles (220 km) at 3 knots when submerged. Armament included six 21-inch (533 mm) torpedo tubes located at the bow, with a total of twelve torpedoes, or alternatively, she could carry twelve mines instead of torpedoes. Additionally, HMS Sea Scout was equipped with a 4-inch (102 mm) deck gun. Her wartime service was primarily in the Far East, where she sank numerous Japanese vessels, including twelve sailing ships, two coasters, a sampan, a patrol vessel, a tug with five barges, and two unidentified ships. She survived the war and participated in the 1953 Fleet Review celebrating Queen Elizabeth II’s coronation. Ultimately, she was sold for scrap and arrived at Swansea on 14 December 1965 to be broken up, marking the end of her distinguished service.
