HMS Tobago (1918)

HMS ''Tobago'' was a Thornycroft destroyer which served with the Royal Navy during the Greco-Turkish War. Launched by Thornycroft on 15 July 1918, the vessel followed a design typical of the yard by being faster than the majority of the class, and also had better seakeeping properties thanks to a raised forecastle. The destroyer operated as part of the Grand Fleet for the last few weeks of the First World War, and, after the Armistice, joined the Mediterranean Fleet based in Malta. While serving in off the coast of Turkey, the ship hit a mine on 15 July 1920, exactly two years after being launched. Despite the relative youth of the vessel, the damage was deemed irrepairable and so ''Tobago'' returned to Malta and was sold for scrap on 9 February 1922.

Design and development

''Tobago'' was one of two destroyers ordered by the British Admiralty from Thornycroft in April 1917 as part of the Eleventh War Construction Programme alongside . The design was based on the destroyer built by the shipyard. Compared to the standard S-class vessels, the design, also known as Modified ''Rosalind'', was longer, with a raised forward gun position and torpedo tubes moved to a new position, both of which improved seakeeping. They also had provision for triple mounts for the main torpedo tubes. In a similar way to previous designs, Thornycroft also installed more powerful machinery to give the warship a higher top speed. This also enabled a more stable hull design with a greater beam and a metacentric height of .

With an overall length of and a length of between perpendiculars, ''Tobago'' had a beam of and a draught of . Displacement was normal and full load. Three Yarrow boilers fed steam to two sets of Brown-Curtis geared steam turbines rated at and driving two shafts, giving a design speed of in light load and at full load. Two funnels were fitted, the forward one larger in diameter. A total of of fuel oil were carried, giving a design range of at .

''Tobago''s armament consisted of three QF 4in Mk IV guns on the ship's centreline. One was mounted on the raised forecastle, while another was positioned between the second and third funnels and the last was located aft. The ship also mounted a single 2-pounder (40 mm) pom-pom anti-aircraft gun for air defence. Six torpedoes were launched from two triple rotating mounts located aft with two mounts fitted athwartships. This ship's complement was 90 officers and ratings.

Construction and career

Laid down in May 1917, ''Tobago'' was launched on 15 July 1918 and completed on 2 October that year. The destroyer joined the Fourteenth Destroyer Flotilla just before the end of the First World War. After the Armistice, the Grand Fleet was dissolved. ''Tobago'' was recommissioned on 22 February 1919 and assigned to the Mediterranean Fleet under . The ship was assigned to Malta to support of British interests in the Greco-Turkish War. While on patrol on 15 July 1920, ''Tobago'' hit a mine off the coast from Trabzon. The damage was deemed uneconomic to repair and, on 15 December 1920, the ship was paid off. The destroyer returned to Malta and was sold for scrap on 9 February 1922.
