Description

Trenchant was 276 feet (84.12 m) long overall, with a beam of 27 feet (8.2 m) and a draught of 11 feet (3.35 m).[2] Displacement was 1,085 long tons (1,102 t). Power was provided by three White-Forster boilers feeding two Brown-Curtis geared steam 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).[3] Two funnels were fitted, two boilers exhausting through the forward funnel. 296 long tons (301 t) of oil was carried, giving a design range of 3,450 nautical miles (6,390 km; 3,970 mi) at 15 knots (28 km/h; 17 mph).[4]

Armament consisted of three QF 4in Mk IV guns on the ship's centreline, with one on the forecastle, one on a raised platform aft and one between the funnels. A single 2-pounder (40 mm) pom-pom anti-aircraft gun was carried, while torpedo armament consisted of two twin mounts for 21 in (533 mm) torpedoes.[2] Fire control included a single Dumaresq and a Vickers range clock.[5] The ship had a complement of 82 officers and men.[3]

Service

Trenchant was one of ten R-class destroyers ordered by the British Admiralty in March 1916 as part of the Eighth War Construction Programme and was launched on 23 December 1916.[4]

On commissioning, Trenchant joined the 15th Destroyer Flotilla of the Grand Fleet,[6] and served there until 1919.[7] When the Grand Fleet was disbanded, Trenchant was transferred to the 5th Destroyer Flotilla of the Home Fleet, under the Flag of King George V,[8] and then acted as a tender to the depot ship Blake.[9] The vessel was reduced to reduced complement on 15 February 1919.[10] While undergoing a refit in Haulbowline on 3 June 1921, Trenchant was attacked by Republican forces during the Irish War of Independence but suffered little damage.[11] The destroyer was sold for scrap on 15 November 1928.[1]

gollark: It seems like Discord just use it to push content restrictions and stuff. Also, their (mandatory for "community" servers) NSFW filter is apparently not good and has high false positive rates.
gollark: :( indeed. I am not really a fan of the "partner" and "community servers" thing.
gollark: I already have a bridge bot running for another server, so it would be easy* to set up!
gollark: We have three servers, plus a fake one running services.
gollark: It is a very excellent IRC network.
