HMS Speedy was an Alarm-class torpedo gunboat of the British Royal Navy. She was built by Thornycroft from 1892–1894. She was converted to a minesweeper in 1908–1909 and continued these duties during the First World War. Speedy was sunk by a German mine on 3 September 1914.
Speedy 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 and the five torpedo-gunboats of the Dryad-class. The Alarms were slightly modified versions of the previous Sharpshooter-class, with modified engines to improve reliability.[1]
Speedy 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). Speedy differed from other ships of her class in having eight Thornycroft water-tube boilers rather than the locomotive boilers used for the rest of the class, with three funnels being fitted instead of two. The boilers fed two sets of triple-expansion steam engines rated at 3,500 indicated horsepower (2,600 kW), driving two Gunmetal propellers with a diameter of 8 ft 3 in (2.51 m) which gave a design speed of 18.7 knots (21.5 mph; 34.6 km/h).[2][3] The revised machinery arrangements were much more reliable and made it easier to maintain high speed.[2][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]

Speedy was laid down at Thornycroft's Chiswick shipyard on 4 January 1892 and was launched on 18 May 1893.[2] She reached a speed of 20.21 knots (23.26 mph; 37.43 km/h) during sea trials, when her engines delivered 4,703 indicated horsepower (3,507 kW).[6] The ship was completed on 20 February 1894,[2] and was the sixth ship of that name to serve with the Royal Navy.[7]
