HMS Sceptre (P215) was a third-batch S-class submarine built for the Royal Navy during World War II. Completed in April 1943, she spent the majority of her career in the North Sea, off Norway. After an uneventful patrol, the submarine participated in Operation Source, an attack on German battleships in Norway using small midget submarines to penetrate their anchorages and place explosive charges. However, the midget submarine that she was assigned to tow experienced technical difficulties and the mission was aborted. During her next four patrols, Sceptre attacked several ships, but only succeeded in severely damaging one. She was then ordered to tow the submarine X24, which was to attack a floating dry dock in Bergen. The operation, codenamed Guidance, encountered difficulties with the attacking submarine's charts, and the explosives were laid on a merchant ship close to the dock instead. The dock was damaged and the ship sunk, and X24 was towed back to England. Sceptre then conducted a patrol in the Bay of Biscay, sinking two German merchant ships, before being reassigned to tow X24 to Bergen again. The operation was a success, and the dry dock was sunk.
HMS Spiteful was a third-batch S-class submarine built for the Royal Navy during the Second World War.
HMS Stonehenge was an S-class submarine of the third batch built for the Royal Navy during World War II. Completed in 1943, she made her initial patrol off Norway and was then transferred to the Far East, where she conducted two war patrols, during which she sank two Japanese ships. On her second patrol, Stonehenge disappeared with all hands and was declared overdue on 20 March 1944. The most probable cause of her sinking is that she hit a mine, but her wreck has never been found.
HMS Stratagem was a third-batch S-class submarine built for the Royal Navy during World War II. Completed in 1943, she made her first war patrol off Norway before she was sent to the Far East, where she conducted three war patrols. On her second, she shelled installations on a Japanese-held island. Her only success came on her last patrol, when she torpedoed and sank a Japanese oil tanker. Soon after, she was spotted by aircraft and depth charged by a destroyer. She was forced to surface, and was scuttled to prevent her capture. Ten crew members escaped the sinking submarine and were taken prisoner, of whom only three survived the war.

Arriving in February 1944, the boat conducted several patrols in the Strait of Malacca, sinking one transport, one gunboat, one merchant, three sailing vessels, two coasters, and one lighter. During this time, she was attacked several times by aircraft and surface ships; in one attack, she took on two tons of water from leaks caused by depth charges. Sea Rover collided with an Australian corvette in December 1944, and she was sent back to England, then the United States, for repairs. After the war ended, the boat was sent back to England, placed in reserve, then sold for scrap in October 1949.

During her next three patrols in the Strait of Malacca, Shalimar sank twelve sailing vessels, eleven landing craft, four coasters, three lighters, three tugboats, and one minesweeper. After the war ended, the boat was sent back to England, placed in reserve, then sold for scrap in July 1950.
