HMS Tenacious was an R-class destroyer that served in the Royal Navy during the First World War. The R class were an improvement on the previous M class with geared steam turbines to improve efficiency. Launched in 1917, Tenacious served with the Eleventh Destroyer Flotilla of the Grand Fleet. The destroyer had a generally uneventful war. Despite sailing in 1918 to engage the German High Seas Fleet in one of the final sorties of war, the destroyer did not see the enemy fleet and no shots were fired. After the Armistice, the ship was stationed at Devonport. Following a decision to replace older destroyers in the Royal Navy, Tenacious was retired in 1928 and sold to be broken up.
Tenacious was one of 23 R-class destroyers ordered by the British Admiralty in March 1916 as part of the Seventh War Programme during the First World War.[1] The design was generally similar to the preceding M class, but differed in having geared steam turbines, giving greater fuel efficiency, the aft gun mounted on a raised platform, higher forecastle for better seakeeping and a larger and more robust bridge structure.[2][3][4]
The destroyer had a length of 265 feet (81 m) between perpendiculars and 276 feet (84 m) overall, a beam of 26 feet 9 inches (8 m) and a draught of 9 feet (3 m).[5] Displacement was 975 long tons (991 t) normal and 1,173 long tons (1,192 t) deep load. Power was provided by three Yarrow boilers feeding two Brown-Curtis geared turbines rated at 27,000 shaft horsepower (20,000 kW) and driving two shafts, to give a design speed of 36 knots (67 km/h; 41 mph). Three funnels were fitted. A total of 296 long tons (301 t) of fuel oil was carried, which gave a design range of 3,450 nautical miles (6,390 km; 3,970 mi) at 15 knots (28 km/h; 17 mph).[2]
Armament consisted of three single 4 in (102 mm) Mk IV guns on the ship's centreline, with one on the forecastle, one aft on a raised platform and one between the second and third funnels. A single 2-pounder 40 mm (2 in) "pom-pom" anti-aircraft gun was carried, while torpedo armament consisted of two twin mounts for 21 in (533 mm) torpedoes.[2] The destroyer was later fitted with racks and storage for depth charges.[6] The number of depth charges available increased in service. By 1918, the vessel was carrying between 30 and 50 depth charges.[7] The ship had a complement of 82 officers and ratings.[5]
