HMS Stoic was a S-class submarine of the third batch built for the Royal Navy during World War II. She survived the war and was scrapped in 1950.
The third batch was slightly enlarged and improved over the preceding second batch of the S-class. The submarines had a length of 217feet overall, a beam of 23feet and a draft of 14feet. They displaced 842LT on the surface and 990LT submerged.[1] The S-class submarines had a crew of 48 officers and ratings. They had a diving depth of 300feet.[2]
For surface running, the boats were powered by two 9500NaN0 diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 650hp electric motor. They could reach 15kn on the surface and underwater.[3] On the surface, the third batch boats had a range of 6000nmi at and 120nmi at submerged.[2]
The boats were armed with seven 21 inch (533 mm) 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.[4]
HMS Stoic was built by Cammell Laird and launched on 9 April 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.[5] Stoic was sold in July 1950 to be broken up at Dalmuir.
