The third and by far the most numerous group of S-class submarines consisted of 50 boats. They were the largest and most heavily armed of the S-class and required more men to crew. They were one knot faster on the surface, but two knots slower when submerged. Most of the group were built at the yards of either Scotts, of Greenock or Cammell Laird & Co Limited, of Birkenhead, with a handful being built at Chatham, or by Vickers Armstrong Ltd, of Barrow-in-Furness. Construction was carried out throughout the war, particularly between 1941 and 1945. Equipped with a greater fuel capacity than their predecessors, they operated much further afield, in the Mediterranean and in the Pacific far east.
There were two distinct subgroups. The first were boats of 842 tons, comprising those ordered under the 1939 War Emergency, 1940 and 1941 Programmes (except Sea Devil and Scotsman), plus the Sturdy and Stygian of the 1942 Programme; these carried an external stern torpedo tube in addition to the six bow tubes. The second subgroup were boats of 814 tons, comprising the Sea Devil and Scotsman of the 1941 Programme, plus those ordered under the 1942 and 1943 Programmes (except Sturdy and Stygian); these carried no external torpedo tube, but had a thicker welded pressure hull providing for an operational depth limit of 350 feet - compared with the 300 feet limit in the first subgroup.
Losses continued to be high. Nine ships; P222, Saracen, Sahib, Sickle, Simoom, Splendid, Stonehenge, Stratagem and Syrtis were lost during the war, and Shakespeare and Strongbow were so badly damaged that they were written off and scrapped. Many surviving ships remained in service after the war. Sportsman, by now transferred to the French navy, was lost off Toulon in 1951 and Sidon was sunk after a torpedo malfunction in 1955.
