The Tribals were intended to counter the large destroyers being built abroad and to improve the firepower of the existing destroyer flotillas and were thus significantly larger and more heavily armed than the preceding I class.[1] The ships displaced 1,891 long tons (1,921 t) at standard load and 2,519 long tons (2,559 t) at deep load.[2] They had an overall length of 377 feet (114.9 m), a beam of 36 feet 6 inches (11.13 m)[3] and a draught of 11 feet 3 inches (3.43 m).[4] The destroyers were powered by two Parsons geared steam turbines, each driving one propeller shaft using steam provided by three Admiralty three-drum boilers. The turbines developed a total of 44,000 shaft horsepower (33,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph).[3] During her sea trialsBedouin made 37.5 knots (69.5 km/h; 43.2 mph) from 44,522 shp (33,200 kW) at a displacement of 2,035 long tons (2,068 t).[5] The ships carried enough fuel oil to give them a range of 5,700 nautical miles (10,600 km; 6,600 mi) at 15 knots (28 km/h; 17 mph).[4] The ships' complement consisted of 190 officers and ratings, although the flotilla leaders carried an extra 20 officers and men consisting of the Captain (D) and his staff.[6]
The ships were fitted with a single above-water quadruple mount for 21-inch (533 mm) torpedoes.[6] The Tribals were not intended as anti-submarine ships, but they were provided with ASDIC, one depth charge rack and two throwers for self-defence, although the throwers were not mounted in all ships.[9] Twenty depth charges was the peacetime allotment, but this increased to 30 during wartime.[10]
Wartime modifications
Heavy losses to German air attack during the Norwegian Campaign demonstrated the ineffectiveness of the Tribals' anti-aircraft suite and the RN decided in May 1940 to replace 'X' mount with two QF 4-inch (102 mm) Mark XVIdual-purpose guns in a twin-gun mount. To better control the guns, the existing rangefinder/director was modified to accept a Type 285gunnery radar as they became available. The number of depth charges was increased to 46 early in the war, and still more were added later.[11] To increase the firing arcs of the AA guns, the rear funnel was shortened and the mainmast was reduced to a short pole mast.[12]
Construction and career
Authorized as one of nine Tribal-class destroyers under the 1936 Naval Estimates,[13]Bedouin was the second ship of her name to serve in the Royal Navy.[14] The ship was ordered on 19 June 1936 from William Denny and was laid down on 13 January 1937 at the company's Dumbartonshipyard. Launched on 21 December, Bedouin was completed on 15 March 1938 and commissioned the previous day at a cost of £340,400 which excluded weapons and communications outfits furnished by the Admiralty.[15]
