Design and description
The third batch was slightly enlarged and improved over the preceding second batch of the S-class. The submarines had a length of 217 feet (66.1 m) overall, a beam of 23 feet 9 inches (7.2 m) and a draft of 14 feet 8 inches (4.5 m). They displaced 842 long tons (856 t) on the surface and 990 long tons (1,010 t) submerged. The S-class submarines had a crew of 48 officers and ratings. They had a diving depth of 300 feet (91.4 m).
For surface running, the boats were powered by two 950-brake-horsepower (708 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 650-horsepower (485 kW) electric motor. They could reach 15 knots (28 km/h; 17 mph) on the surface and 10 knots (19 km/h; 12 mph) underwater. On the surface, the third batch boats had a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 10 knots (19 km/h; 12 mph) and 120 nmi (220 km; 140 mi) at 3 knots (5.6 km/h; 3.5 mph) submerged.
The boats were armed with seven 21-inch torpedo tubes. A half-dozen of these were in the bow and there was one external tube in the stern. They carried six reload torpedoes for the bow tubes for a grand total of thirteen torpedoes. Twelve mines could be carried in lieu of the internally-stowed torpedoes. They were also armed with a 3-inch (76 mm) deck gun.
Construction and career
HMS Stoic was built by Cammell Laird and launched on April 9, 1943. Thus far she has been the only ship of the Royal Navy to bear the name Stoic. She survived the Second World War, spending most of it with the Eastern Fleet, where she sank six small Japanese sailing vessels, the Japanese transport ship Kainan Maru, a landing craft, the Japanese fishing vessel Nanyo Maru No.55, the Japanese auxiliary gunboat Shoei Maru and a Japanese coaster. Stoic also bombarded warehouses and fuel tanks at Jangka Island. Stoic was sold in July 1950 to be broken up at Dalmuir.
