The Tribals were intended to counter the large destroyers being built abroad and to lend gun support to the existing destroyer flotillas and were thus significantly larger and more heavily armed than the preceding. The ships displaced at standard load and at deep load. They had an overall length of, a beam of and a draught of. 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 and gave a maximum speed of. The ships carried enough fuel oil to give them a range of at. The ships' complement consisted of 190 officers and ratings, although the flotilla leaders carried an extra 20 officers and men for the Captain and his staff. The primary armament of the Tribal-class destroyers was eight quick-firing 4.7-inch Mark XII guns in four twin-gun mounts, designated 'A', 'B', 'X', and 'Y' from front to rear. For anti-aircraft defence, they carried a single quadruple mount for the QF two-pounder Mk II "pom-pom" AA gun and two quadruple mounts for the 0.5-inch Mark IIImachine gun. The ships were fitted with a single above-water quadruple mount for British 21 inch torpedo| torpedoes. 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; Twenty depth charges were the peacetime allotment, but this increased to 30 during wartime.
Construction and career
On 10 March 1936, two Tribal-class destroyers were ordered from Fairfield Shipbuilding and Engineering Company, Gurkha and. Both ships were laid down at Fairfield's Govan, Glasgow shipyard on 6 July 1936, and Gurkha was launched on 7 July 1937. Like many of the Tribals, completion of Gurkha, originally scheduled for February 1938, was delayed by late delivery of equipment, and she was not completed until 21 October 1938. On commissioning, Gurkha joined the First Tribal Flotilla as part of the Mediterranean Fleet. She was involved in exercises and port visits until the outbreak of war, suffering minor damage in a collision with sister-ship. In September 1939, Gurkha was one of a group of ships assigned to monitor Italian naval activity in the Red Sea. In October 1939 the flotilla was reassigned to the Home Fleet, on escort duty from Portland. Gurkha, like many of the Tribals, suffered from mechanical defects including problem's with the ship's turbines and leaks in the reserve feed tanks, and underwent repair at Thornycroft's Southampton shipyard from December 1939 to January 1940, before rejoining her Flotilla, now based at Scapa Flow. On the night of 23/24 February 1940, Gurkha spotted the German submarine on the surface between the Faroe Islands and Orkney Islands. She attacked and sank the enemy south of the Faroe Islands on 23 February 1940. U-53 dived to avoid a ramming attempt by Gurkha. Gurkha responded with a series of depth charge attacks, sinking U-53 with the loss of all hands. On 9 April 1940, Germany invaded Norway, and Gurkha was part of a naval force detached from the Home Fleet to attack Bergen, where a German cruiser was reported. The attack was cancelled by the British Admiralty, however, and the British force was attacked by 47 German Ju 88 and 41 He 111 bombers of Kampfgeschwader 30 and Kampfgeschwader 26. In an attempt to obtain better firing conditions, Gurkha moved away from the mutual protection of the naval force. She then became an easy target for concentrated air attack and soon was stopped by a single bomb hit. The crew were rescued by the cruiser Aurora and the destroyer Mashona, with Gurkha sinking with the loss of 16 of her crew.
