Janissaire was one of four Chasseur-class destroyers built for the French Navy in the first decade of the 20th century.

Design and description[]

The Chasseur class was based on the preceding Spahi-class destroyer, albeit oil-fired boilers rather than the coal-fired ones of the earlier ships.^[1] Janissaire had an length between perpendiculars of 64.5 meters (211 ft 7 in), a beam of 6.6 meters (21 ft 8 in),^[2] and a draft of 3.1 meters (10 ft 2 in). Designed to displaced 450 metric tons (443 long tons), the ships displaced 520 t (512 long tons) at deep load. Their crew numbered 77–79 men.^[1]

Janissaire was powered by three Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by three Foster-Wheeler boilers. The engines were designed to produce 7,200 shaft horsepower (5,400 kW) which was intended to give the ships a speed of 28 knots (52 km/h; 32 mph). Janissaire exceeded that speed during her sea trials, reaching 28.6 knots (53.0 km/h; 32.9 mph). The ships carried enough fuel oil to give them a range of 1,400–1,500 nautical miles (2,600–2,800 km; 1,600–1,700 mi) at a cruising speed of 10 knots (19 km/h; 12 mph).^[3]

The primary armament of the Chasseur-class ships consisted of six 65-millimeter (2.6 in) Modèle 1902 guns in single mounts, one each fore and aft of the superstructure and the others were distributed amidships. They were also fitted with three 450-millimeter (17.7 in) torpedo tubes. One of these was in a fixed mount in the bow and the other two were on single rotating mounts amidships.^[1]

Construction and career[]

Janissaire was ordered from Ateliers et Chantiers de Penhoët and was launched from its Saint-Nazaire shipyard on 12 April 1910. The ship was completed in June 1911. She survived the First World War to be condemned in October 1920.^[4]
