HMS Whirlwind (R87)
Résumé
The second HMS Whirlwind was a W-class destroyer of the British Royal Navy and was built by Hawthorn Leslie and was launched on 30 August 1943. She saw service during World War II and the Cold War.
Whirlwind was one of eight W-class destroyers ordered as the 9th Emergency Flotilla on 3 December 1941. The W-class were War Emergency Programme destroyers, intended for general duties, including use as anti-submarine escort, and were to be suitable for mass-production. They were based on the hull and machinery of the pre-war J-class destroyers, but with a lighter armament (effectively whatever armament was available) in order to speed production. The W-class were almost identical to the U-class ordered as the 7th Emergency Flotilla and the V-class ordered as the 8th Emergency Flotilla earlier in the year, with the major difference the fitting of a new dual-purpose fire control director, capable of directing both anti-aircraft and anti-aircraft fire.
Whirlwind was laid down at Hawthorn Leslie's Hebburn, Tyneside shipyard on 31 July 1942, was launched on 30 August 1943 and was completed on 20 July 1944.
The W-class were long overall, at the waterline and between perpendiculars, with a beam of and a draught of mean and full load. Displacement was standard and full load. Two Admiralty 3-drum water-tube boilers supplied steam at and to two sets of Parsons single-reduction geared steam turbines, which drove two propeller shafts. The machinery was rated at giving a maximum speed of ( at full load). 615 tons of oil were carried, giving a range of at .
The ship had a main gun armament of four 4.7 inch (120 mm) QF Mk. IX guns, capable of elevating to an angle of 55 degrees, giving a degree of anti-aircraft capability. The close-in anti-aircraft armament for the class was one Hazemayer stabilised twin mount for the Bofors 40 mm gun and four twin Oerlikon 20 mm cannons. Two quadruple mounts for 21 inch (533 mm) torpedoes were fitted, while the ship had an depth charge outfit of four depth charge mortars and two racks, with a total of 70 charges carried.
