HMS Jason was a Alarm-class torpedo gunboat of the British Royal Navy. She was built by the Naval Construction & Engineering Co. from 1891–1893. She was converted to a minesweeper in 1908–1909 and continued these duties during the First World War. Jason was sunk by a German mine on 7 April 1917.

Design and construction

edit

Jason was one of 11 Alarm-class torpedo gunboats ordered for the Royal Navy under the 1889 Naval Defence Act, which authorised the shipbuilding programme for the next five years, and also included the last two torpedo-gunboats of the Sharpshooter-class torpedo gunboat and the five torpedo-gunboats of the Dryad-class torpedo gunboat. The Alarms were slightly modified versions of the previous Sharpshooter-class, with modified engines to improve reliability.[1]

Jason was 230 feet (70.10 m) long between perpendiculars, with a beam of 27 feet (8.23 m) and a draught of 12 feet (3.66 m). Displacement was 810 long tons (820 t). Two triple-expansion steam engines, fed by four locomotive boilers, drove two propeller shafts. The machinery was heavier than that installed in the Sharpshooters, and was slightly downrated (from 3,600 indicated horsepower (2,700 kW) to 3,500 indicated horsepower (2,600 kW)) to improve reliability. This gave a speed of 18.7 knots (21.5 mph; 34.6 km/h).[2][3][4]

The ship was armed with two 4.7 inch (120 mm) QF guns mounted fore and aft on the ships centreline, backed up by four 3-pounder (47 mm) guns (two in single mounts on the ship's beam and two in casemates forward) and a single .45-inch Gardner machine gun. Three 18-inch (450 mm) torpedo tubes were fitted, with one fixed in the ship's bow and the other two on swivelling mounts on the beam.[2][5] The ship had a crew of 91.[2]

Jason was laid down at the Naval Construction & Engineering Co.'s (later Vickers Armstrong) Barrow-in-Furness shipyard on 7 September 1891, was launched on 14 May 1892 and completed in June 1893 at a cost of £49,253.[2][6]

Service

edit

In August 1894 Jason took part in that year's Naval Manoeuvres,[7] but, owing to problems with her engines, was sent into Milford Haven for repair.[8] In July 1896 she again took part in the Manoeuvres,[9] On 26 June 1897 Jason was present at the Jubilee Fleet Review at Spithead.[10] Jason took part in the 1900 Naval Manoeuvres in July that year.[11]

Jason left Plymouth for Glasgow in September 1902,[12] and was fitted by the Fairfield Shipbuilding and Engineering Company with water-tube boilers and new engines, which were rated at 5,800 indicated horsepower (4,300 kW) in 1903. During sea trials, the refitted ship reached a speed of 21.9 knots (25.2 mph; 40.6 km/h).[13][14] Jason returned to Sheerness following her re-engining refit on 14 July 1903.[15]

Jason was in reserve at Chatham in 1906, but joined the Home Fleet in 1907.[16] In June 1909, after refit, Jason rejoined the Nore Destroyer Flotilla.[17]

Jason was converted to a minesweeper in 1909,[16][18] She had her boilers re-tubed at Sheerness Dockyard at the end of 1911,[19] and rejoined the Nore division of the Home Fleet at the end of the refit in April 1912.[20]

On the outbreak of the First World War Jason joined the newly established Grand Fleet.[21] In August 1914, the minesweepers attached to the Grand Fleet, including Jason were employed on carrying out daily sweeps of the Pentland Firth.[22] On 17 December 1914, Jason and the torpedo gunboats Gossamer and Skipjack were on passage from Lowestoft to Scapa Flow, when they were temporarily diverted to help to deal with a minefield laid off Scarborough on 16 December.[23]

On 7 April 1917,[24][25][26][a] Jason and sister ship Circe were sweeping a minefield between Mull and Coll in the Inner Hebrides, Western Scotland, when Jason struck a mine which had been laid by the German submarine U-78 on 12 February. Jason sank, with Circe rescuing the survivors.[24][28] 25 of Jason's crew were killed.[24][29][b]
