HMS Derwent was a Template:Sclass2- Type III destroyer escort of the Royal Navy. She was built by Vickers-Armstrongs, Barrow-in-Furness and served during the Second World War.
Construction and design
Derwent was one of seven Type III Hunt-class destroyers ordered for the Royal Navy on 4 July 1940, as part of the 1940 War Emergency Programme.[1] The Hunt class was meant to fill the Royal Navy's need for a large number of small destroyer-type vessels capable of both convoy escort and operations with the fleet. The Type III Hunts differed from the previous Type II ships in replacing a twin 4-inch gun mount by two torpedo tubes to improve their ability to operate as destroyers.[2][3]
The Type III Hunts were 264 feet 3 inches (80.54 m) long between perpendiculars and 280 feet (85.34 m) overall, with a beam was 31 feet 6 inches (9.60 m) and draught 7 feet 9 inches (2.36 m). Displacement was 1,050 long tons (1,070 t) standard and 1,490 long tons (1,510 t) under full load. Two Admiralty boilers raising steam at 300 pounds per square inch (2,100 kPa) and 620 °F (327 °C) fed Parsons single-reduction geared steam turbines that drove two propeller shafts, generating 19,000 shaft horsepower (14,000 kW) at 380 rpm. This gave a design maximum speed of 27 knots (50 km/h; 31 mph).[4] 345 long tons (351 t) of oil fuel were carried, giving a range of 3,700 nautical miles (6,900 km; 4,300 mi) at 15 knots (28 km/h; 17 mph).[5]
Main gun armament was four 4 inch (102 mm) QF Mk XVI dual purpose (anti-ship and anti-aircraft) guns in two twin mounts, with a quadruple 2-pounder "pom-pom" and three Oerlikon 20 mm cannon providing close-in anti-aircraft fire.[6][4] Two 21-inch (533 mm) torpedo tubes were fitted in a single twin mount, while two depth charge chutes, four depth charge throwers and 70 depth charges comprised the ship's anti-submarine armament. Type 291 and Type 285 radars was fitted, as was Type 128 sonar.[6][7]
Derwent was laid down at Vickers Armstrong's Barrow-in-Furness shipyard on 12 December 1940, was launched on 22 August 1941 and was completed on 24 April 1942.[1][8]
Service history
On 19 March 1943 while anchored in Tripoli harbour, Libya, Derwent was hit by a Motobomba (pattern-running torpedo) launched by an Italian aircraft.[9] Another, more specific source, says the destroyer was damaged by I./KG 54 and KG 77, which also sank the Ocean Voyager (7,174 grt), Greek steamer Vavara (1,654 grt).[10]
Derwent was beached to prevent her from sinking and was later temporarily repaired and towed to England. Some repairs were carried out, but the decision was taken to suspend work in January 1945 and she was reduced to the reserve, and finally scrapped in 1947.
