Design

Ursa 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).[1] Displacement was 1,085 long tons (1,102 t).[2] Power was provided by three Yarrow boilers feeding two Parsons 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).[1] Two funnels were fitted, two boilers exhausting the fore funnel. 296 long tons (301 t) of oil were carried, giving a design range of 3,450 nautical miles (6,390 km; 3,970 mi) at 15 knots (28 km/h; 17 mph).[3]

Armament consisted of three QF 4in Mk IV guns on the ship's centreline, with one on the forecastle, one aft on a raised platform and one between the funnels. They could elevate to 30°.[2] 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.[1] Fire control included a single Dumaresq and a Vickers range clock.[4] The ship had a complement of 82 officers and men.[2]

Service

Ursa 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 in July 1917.[3]

On commissioning, Ursa joined the Thirteenth Destroyer Flotilla of the Grand Fleet,[5] On 28 September 1917, Commander John Tovey took over command of the vessel, a position that he held until 2 April 1918.[6]

On 17 November 1917, Ursa took part in the Second Battle of Heligoland Bight in support of the 1st Cruiser Squadron, led by Vice-Admiral Trevylyan Napier in Courageous.[7] Leading a destroyer force that included sisterships Urchin and Umpire, as well as Nerissa, the destroyer was one of the first to launch torpedoes at the German ships in the action.[8] It was while commanding Ursa that Tovey was awarded the Croix de Guerre "for distinguished services rendered during the war".[9] At the end of World War I, the destroyer was still part of the Thirteenth Destroyer Flotilla under the cruiser Champion.[10]

When the Grand Fleet was disbanded, Ursa was transferred to the Home Fleet, under the Flag of King George V,[11] remaining with the battleship on reserve at Portsmouth from 13 December 1919.[12] The ship was sold for scrap to J. Smith on 13 July 1928 and broken up.[13]
