The French destroyer Opiniâtre was one of four Template:Sclass-s that was built for the Argentine Navy in the early 1910s. The ships were taken over by the French Navy after the start of the First World War in August 1914. She was scrapped in 1935.

Design and description

The ships had an overall length of 88.5 meters (290 ft 4 in), a beam of 8.6 meters (28 ft 3 in), and a draft of 3.1 meters (10 ft 2 in). They displaced 930 metric tons (915 long tons) at normal load and 1,250 t (1,230 long tons) at deep load. Their crew numbered 140 men.

The ships were powered by a pair of Rateau steam turbines, each driving one propeller shaft using steam provided by five mixed-firing Foster-Wheeler boilers. The engines were designed to produce 18,000 shaft horsepower (13,000 kW) which was intended to give the ships a speed of 32 knots (59 km/h; 37 mph). The ships carried 230 t (226 long tons) of coal and 72 t (71 long tons) of fuel oil that gave them a range of 1,850 nautical miles (3,430 km; 2,130 mi) at a cruising speed of 10 knots (19 km/h; 12 mph).

The primary armament of the Aventurier-class ships consisted of four 100-millimeter (3.9 in) guns in single mounts, one on the forecastle, one between the funnels, and two on the quarterdeck, in front and behind the searchlight platform. They were fitted with a 47-millimeter (1.9 in) AA gun for anti-aircraft defence. The ships were also equipped with four single mounts for 450-millimeter (17.7 in) torpedo tubes amidships.

Construction and career

Opinâtre was ordered from Dyle et Bacalan and was launched in 1911 with the name of La Rioja at its [Bordeaux]] shipyard. The ship was completed on 16 September 1914. She was struck in 1933 and broken up for scrap in 1935.
