The S-class submarines of the Royal Navy were originally designed and built during the modernisation of the submarine force in the early 1930s to meet the need for smaller boats to patrol the restricted waters of the North Sea and the Mediterranean Sea replacing the H class submarines. Due to major naval construction of the Royal Navy during the Second World War, however, the S class became the largest single group of submarines ever built for the Royal Navy; a total of 62 were constructed over a period of 15 years, with fifty of the "improved" S-class launched between 1940 and 1945.

[edit] Service
The submarines operated in the waters around the United Kingdom and in the Mediterranean, and later in the Far East after being fitted with extra tankage.
After the war S class boats continued to serve in the Royal Navy until the 1960s. The last operational boat in the Royal Navy was HMS Sea Devil, launched in 1945 and scrapped in February 1966.
Several S-class submarines were sold on or lent to other navies:
- Netherlands 1
- Portugal 3
- France 4
- Israel 2.
A modified version was ordered by the Turkish navy in 1939 as the Oruc Reis class submarine.
[edit] Service losses
Of the twelve S-boats that were in service in 1939, only three survived to see the end of World War II, a loss rate that inspired the song "Twelve Little S-Boats", based on a nursery rhyme originally written by Septimus Winner in 1868.[1]
- Twelve little S-boats "go to it" like Bevin,
- Starfish goes a bit too far — then there were eleven.
- Eleven watchful S-boats doing fine and then
- Seahorse fails to answer — so there are ten.
- Ten stocky S-boats in a ragged line,
- Sterlet drops and stops out — leaving us nine.
- Nine plucky S-boats, all pursuing Fate,
- Shark is overtaken — now we are eight.
- Eight sturdy S-boats, men from Hants and Devon,
- Salmon now is overdue — and so the number's seven.
- Seven gallant S-boats, trying all their tricks,
- Spearfish tries a newer one — down we come to six.
- Six tireless S-boats fighting to survive,
- No reply from Swordfish — so we tally five.
- Five scrubby S-boats, patrolling close inshore,
- Snapper takes a short cut — now we are four.
- Four fearless S-boats, too far out to sea,
- Sunfish bombed and scrap-heaped — we are only three.
- Three threadbare S-boats patrolling o'er the blue,
- ...
- Two ice-bound S-boats...
- ...
- One lonely S-boat...
- ...
The survivors, left blank in the fatalistic rhyme, were Sealion, Seawolf and Sturgeon.
[edit] General characteristics
[edit] First Group
| Class overview | |
|---|---|
| Name: | First group |
| Completed: | 4 |
| General characteristics | |
| Type: | Submarine |
| Displacement: | 640 tons surfaced 935 tons submerged |
| Length: | 202 ft 6 in (61.7 m) |
| Beam: | 24 ft (7.3 m) |
| Draught: | 10 ft 6 in (3.2 m) |
| Speed: | 13.75 knots surfaced 10 knots (19 km/h) submerged |
| Complement: | 36 officers and men |
| Armament: | six forward 21-inch (533 mm) torpedo tubes twelve torpedoes one three-inch (76 mm) gun one .303-calibre machine gun |
The first group of S-class submarines consisted of four boats. They were smaller and slower than later classes, and carried less armament, but could be crewed by fewer men. All four were built at Chatham Dockyard, between 1930 and 1932. During the war, they operated in home waters, particularly the English Channel, and off the Scandinavian coast. The later second and third groups of S-class submarines would have their fuel capacity expanded to allow them to operate further and overcome this limitation.
The mortality rate of these early ships was particularly high. Only one, HMS Sturgeon, survived to the end of the war.

[edit] Second Group
The second group of S-class submarines consisted of eight boats. They were larger than the preceding first group and required more men to crew, but carried a similar armament. Construction was divided between Chatham Dockyard, and the yards of Scotts, of Greenock and Cammell Laird & Co Limited, of Birkenhead. All the ships were built between 1934 and 1937. During the war, they, like the submarines of the first group, mostly operated in home waters, ranging as far afield as the Bay of Biscay and the Scandinavian coast. One, HMS Sunfish, was assigned to the Soviet Navy and operated in the Baltic Sea, before she was sunk by friendly aircraft.
A large percentage of these submarines were also lost during the war. Only two, HMS Sealion and HMS Seawolf survived to the end of the war.

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.
