The Bourrasque class was a group of twelve French Navy destroyers (torpilleur) laid down in 1923 and in service from 1926 to 1950. Along with the heavier , they were part of a plan to modernise the French fleet after the First World War. The Bourrasques were smaller and slower than the Chacals, but were nonetheless comparable with the British W class. The class saw varied service in the Second World War, in five different navies, on both sides. These ships were named after types of wind. The design was used as the basis for the two s built for the Polish Navy during the late 1920s. Design and description The Bourrasque class had an overall length of , a beam of , and a draft of . The ships displaced at (standard) load and at deep load. They were powered by two geared steam turbines, each driving one propeller shaft, using steam provided by three du Temple boilers. The turbines were designed to produce , which would propel the ship at . The ships carried enough fuel oil to give them a range of at . The main armament of the Bourrasque-class ships consisted of four Canon de Modèle 1919 guns in shielded single mounts, one superfiring pair each fore and aft of the superstructure. Their anti-aircraft (AA) armament consisted of a single Canon de Modèle 1924 gun. The ships carried two triple mounts of torpedo tubes amidships. A pair of depth charge chutes were built into their stern that housed a total of sixteen depth charges. Ships Service Four ships of the class - Bourrasque, Cyclone, Orage and Sirocco - were lost in 1940; Orage on 23 May, sunk by German bombers; Bourasque by German mines and artillery fire on 30 May while evacuating troops from Dunkirk; Sirocco on 31 May, to German torpedo boats while engaged in the same operation; and Cyclone, having been badly damaged on 30 May by torpedo boats was scuttled at Brest on 18 June to prevent her capture. Mistral and were captured by the British in Plymouth harbour on 3 July 1940 during Operation Catapult. Both were eventually transferred to the Free French.
