HMS TB 11 (1907)

HMS TB 11 (originally named HMS Mayfly) was a Cricket-class coastal destroyer or torpedo-boat of the British Royal Navy. TB 11 was built by the shipbuilder Yarrow from 1905 to 1907. She was used for local patrol duties in the First World War and was sunk by a German mine in the North Sea on 7 March 1916.

Design

The Cricket-class was intended as a smaller and cheaper supplement to the large, fast but expensive Tribal-class, particularly in coastal waters such as the English Channel.[1][2] An initial order for twelve ships was placed by the Admiralty in May 1905 as part of the 1905–1906 shipbuilding programme, with five ships each ordered from Thornycroft and J. Samuel White and two from Yarrow.[1]

Yarrow's ships (the different shipbuilders built to their own design, although standardised machinery and armament was fitted) were 175 feet 9 inches (53.57 m) long overall and 172 feet 0 inches (52.43 m) between perpendiculars, with a beam of 18 feet 0 inches (5.49 m) and a draught of 5 feet 8 inches (1.73 m).[3] The ships had turtleback[lower-alpha 1] forecastles and two funnels. Two oil-fuelled Yarrow water-tube boilers fed steam to three-stage Parsons steam turbines, driving three propeller shafts.[5][2] The machinery was designed to give 4,000 shaft horsepower (3,000 kW), with a speed of 26 knots (30 mph; 48 km/h) specified.[3]

Armament consisted of two 12-pounder (76-mm) 12 cwt guns[lower-alpha 2], and three 18-inch (450 mm) torpedo tubes (in three single mounts).[5][1] The ships had a crew of 39.[6]

Service

The first of Yarrow's two torpedo-boats of the 1905–1906 programme was laid down as HMS Mayfly at their Poplar, London shipyard on 23 November 1905.[7] In 1906, the ships of the class, including Mayfly , were redesignated as torpedo-boats, losing their names in the process, with Mayfly becoming TB 11.[5] She was launched on 29 January 1907, and reached a speed of 27.16 knots (31.26 mph; 50.30 km/h) during sea trials. She was completed in July 1907.[8]

In August 1910, TB 11 collided with the sea wall at the eastern entrance to Dover harbour when carrying out a practice night torpedo attack, damaging her stem. She was taken into Sheerness dockyard for repair on 3 August.[9] She was refitted at Sheerness in 1911.[10]

TB 11 was sunk by a mine off Longsand Head on the east coast of Britain on 7 March 1916. 23 of her crew was killed. The destroyer Coquette was lost in the same minefield, which had been laid by the German submarine UC-10 on 6 March, shortly before TB 11 was sunk.[11][12][13]

Notes
  1. A fore deck with exaggerated camber designed to throw off sea water at high speeds.[4]
  2. 12 cwt refers to the weight of the gun in hundredweights

gollark: I agree. From a perspective of equality, the existence of families is quite bad.
gollark: Just do it in the minimum physically possible time.
