HMS Somme was an Admiralty S-class destroyer built for the Royal Navy during World War I. Commissioned seven days before the end of the war, the ship was sold for scrap in 1932.
The Admiralty S class were larger and faster versions of the preceding R class.[1] The ships had an overall length of 276 feet (84.1 m), a beam of 26 feet 8 inches (8.1 m) and a deep draught of 9 feet 10 inches (3 m). They displaced 1,000 long tons (1,016 t) at normal load. The ship's complement was 82 officers and ratings.[2]
The ships were powered by a single Brown-Curtis geared steam turbine that drove two propeller shafts using steam provided by three Yarrow boilers. The turbines developed a total of 27,000 shaft horsepower (20,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). Somme reached a speed of 33.7 knots (62.4 km/h; 38.8 mph) during her sea trials.[3] The ships carried enough fuel oil to give them a range of 3,500 nautical miles (6,500 km; 4,000 mi) at 15 knots (28 km/h; 17 mph).[2]
The Admiralty S-class ships were armed with three single QF 4-inch (102 mm) Mark IV guns. One gun was positioned on the forecastle, the second was on a platform between the funnels and the third at the stern. They were equipped with a single QF 2-pounder (40 mm (1.6 in)) "pom-pom" anti-aircraft gun on a platform forward of the mainmast. They were also fitted with two rotating twin mounts for 21-inch (533 mm) torpedoes amidships and two 18-inch (450 mm) torpedo tubes, one on each broadside abaft the forecastle.[4]
