Tempête was the lead ship for her class of two ironclad coast-defense ships built for the French Navy (Marine Nationale) in the 1870s. Even though the ship was not fully commissioned until 1883, she played a minor role in the French occupation of Tunisia in 1881. Tempête accidentally sank a torpedo boat during night maneuvers in 1892 and was placed in reserve later that year. She became the flagship of the local defenses in French Tunisia in 1897 and was decommissioned in 1907. The ironclad served as a target ship for the next several years until she was sunk in 1909. Her wreck was salvaged beginning in 1912, but it was not completed until 1959.
Armament and armor
The design of the Tempête-class coast-defense ships was based on that of the British breastwork monitors Glatton and Rupert. To maximize the traverse of the single gun turret, the superstructure was as narrow as possible, only 2.5 m (8 ft 2 in) wide. The ships had an overall length of 73.6 m (241 ft 6 in), a beam of 17.8 m (58 ft 5 in) and a draft of 5.33 m (17 ft 6 in) forward and 5.42 m (17 ft 9 in) aft at deep load. They displaced 4,908 metric tons (4,830 long tons) at deep load. The crew of the Tempête class numbered 7 officers and 165 enlisted men.[1]
The Tempête class was powered by a single six-cylinder, horizontal compound-expansion steam engine that drove one propeller shaft using steam provided by four Indret[2] cylindrical boilers. The engine was rated at 2,000 indicated horsepower (1,500 kW)[3] and was intended to give the ships a top speed of 10 knots (19 km/h; 12 mph). During her sea trials Tempête reached a speed of 11.68 knots (21.6 km/h; 13.4 mph) from 2,164 ihp (1,614 kW). The ships carried enough coal to give them a range of 1,103 nautical miles (2,043 km; 1,269 mi) at a speed of 5 knots (9.3 km/h; 5.8 mph).[2]
The Tempêtes carried their main battery of two Canon de 274 mm (10.8 in) Modèle 1875 guns in a single twin-gun turret, forward of the superstructure. Defense from torpedo boats was provided by four Canon de 47 mm (1.9 in) Modèle 1885 Hotchkiss guns and four 37-millimetre (1.5 in) Hotchkiss revolving cannon.[3] The 47 mm guns were positioned on the corners of the hurricane deck on top of the superstructure and the revolver guns were placed between them, two on each broadside.[2]
The ships had a full-length wrought-iron waterline armor belt that tapered from the maximum thickness of 330 mm (13 in) amidships to 250 mm (9.8 in) at the ships' ends. The armored breastwork supporting the superstructure and the turret was 40 meters (131 ft 3 in) long and was also 330 mm thick. The main deck was protected by 50-millimeter (2 in) iron plates, as was the deck below it. The turret armor was 300 mm (11.8 in) thick and was backed by 550 mm (1 ft 10 in) of teak. The plates protecting the conning tower measured 250 mm in thickness.[1]
