The Provence-class ironclads consisted of 10 ironclad frigates built for the French Navy (Marine Nationale) during the 1860s. Only one of the sister ships was built with an wrought iron hull; the others were built in wood.
Design and description
The Provence class was designed by naval architect Henri Dupuy de Lôme as an enlarged version of the Template:Sclass-s with thicker armor, more powerful guns, and better seakeeping qualities. The ships had an overall length of 80.72 meters (264 ft 10 in), with a beam of 17 meters (55 ft 9 in), and a draft of 7.7–8.8 meters (25 ft 3 in – 28 ft 10 in), depending on the load. They displaced between 5,700–6,000 metric tons (5,600–5,900 long tons). All of the ships except Héroïne had wooden hulls; that ship had an iron hull.[1] Like most ironclads of their era they were equipped with a metal-reinforced ram. The Provence-class ships had a metacentric height of about 1.4 meters (4.5 ft) and did not rolled as badly as the Gloires.[2] They had a crew of 579–594 officers and enlisted men.[3]
The ships of the Provence class had a single horizontal-return connecting-rod compound steam engine that drove a four-bladed, 6.1-meter (20 ft) propeller,[4] using steam provided by eight boilers[Note 1] that had a maximum pressure of 1.8 kg/cm2 (177 kPa; 26 psi).[3] The engine was rated at 1,000 nominal horsepower or 3,200 metric horsepower (2,400 kW) and intended to give the ships a speed in excess of 13 knots (24 km/h; 15 mph). Available records of their sea trials show that they achieved speeds of 13.2–16.5 knots (24.4–30.6 km/h; 15.2–19.0 mph) from 2,918–3,895 metric horsepower (2,146–2,865 kW)[3] The Provence class carried between 590–640 t (581–630 long tons) of coal[2] which allowed them to steam for 2,410 nautical miles (4,460 km; 2,770 mi) at a speed of 10 knots (19 km/h; 12 mph).[5] They were fitted with a three-masted barque rig that had a sail area of 1,960 square meters (21,100 sq ft).[4]
The main battery of the Provence-class ships was intended to be thirty 164.7-millimeter (6.5 in) Modèle 1858–60 rifled muzzle-loading (RML) guns, but this was changed to eleven 194-millimeter (7.6 in) Modèle 1864 smoothbore muzzle-loading guns in 1865.[3][4][5] It is uncertain if any received their intended armament, although naval historian N. J. M. Campbell states that Flandre, Provence and Héroïne, three of the first ships completed, were armed with a mix of ten 164.7 mm smoothbores, twenty-two 164.7 mm RMLs and a pair of 220-millimeter (8.7 in) RML howitzers.[2] Ten of the 194 mm Modèle 1864 guns were mounted on the broadside and one was on a pivot mount below the forecastle deck as a chase gun. Three years later, their armament was changed to eight 240-millimeter (9.4 in) RMLs and four 194 mm smoothbores.[3][Note 2]

Notes
- ^ Sources differ on the number of boilers. Gille states that all ships had eight, Campbell say nine and Silverstone says that all of the ships except Revanche had eight while that ship had nine.[2][3][5]
- ^ Sources vary regarding the armament of these ships, especially since dates are not often given. Campbell only gives the 1865 armament while naval historian Angus Konstam only provides the 1868 armament, except for agreeing with Campbell regarding the guns of Flandre, Provence and Héroïne.[2][6]
