French destroyer Siroco (1925)

Siroco was a Bourrasque-class destroyer (torpilleur d'escadre) built for the French Navy during the 1920s.

Design and description
The Bourrasque class had an overall length of 105.6 m, a beam of 9.7 m, and a draft of 3.5 m. The ships displaced 1320 t at (standard) load and 1825 t 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 31000 PS, which would propel the ship at 33 kn. The ships carried enough fuel oil to give them a range of 3000 nmi at 15 kn.

The main armament of the Bourrasque-class ships consisted of four Canon de 130 mm 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 75 mm Modèle 1924 gun. The ships carried two triple mounts of 550 mm torpedo tubes amidships. A pair of depth charge chutes were built into their stern that housed a total of sixteen 200 kg depth charges.

Construction and career
Siroco was torpedoed and sunk by the German S-boats S-23 and S-26 off West Hinder light vessel on 31 May 1940 while participating in the Dunkirk evacuation. Of 930 troops and crew aboard, 660 were killed. The flag of the French Army's 92nd Infantry Regiment was lost in the sinking.
