French ironclad Trident


The French ironclad Trident was the second and last ship of the s that were built for the French Navy in the 1870s. The ship was the flagship of the deputy commander of the Mediterranean Squadron for most of her career. She took part in the French occupation of Tunisia, notably shelling and landing troops in Sfax in 1881. Trident was reclassified as a training ship in 1894 and condemned in 1900, before she was finally sold for scrap in 1909.

Design and description

The Colbert-class ships were designed by Constructor Sabattier as improved versions of the ironclad. As a [Central Artillery battery|battery ship|central battery ironclad], Trident had her armament concentrated amidships. Like most ironclads of her era she was equipped with a plough-shaped ram. Her crew numbered 774 officers and men. The metacentric height of the ship was low, a little above.
The ship measured overall, with a beam of. Trident had a maximum draft of and displaced.

Propulsion

Trident had a single Wolf three-cylinder horizontal return connecting-rod compound steam engine that drove one propeller. The engine was powered by eight oval boilers and was designed for a capacity of. On sea trials, the engine produced and Trident reached. She carried a maximum of of coal which allowed her to steam for approximately at a speed of. Trident was ship rigged with three masts and had a sail area around.

Armament

Trident had two guns mounted in barbettes on the upper deck, one gun at the forward corners of the battery, with six additional guns on the battery deck below the barbettes. The side of the upper deck were cut away to improve the ability of the barbette guns to bear fore and aft. One was mounted in the forecastle as a chase gun. The ship's secondary armament consisted of six guns, four forward of the battery and two aft. These latter two guns were replaced in 1878 by another 240-millimeter gun as a stern chaser. The ship also mounted four above-water torpedo tubes.
All of the ship's guns could fire both solid shot and explosive shells. The 274-millimeter Modèle 1870 gun was credited with the ability to penetrate a maximum of wrought iron armor while the 240-millmeter Modèle 1870 gun could penetrate of wrought iron armor.
At some point the ship received fourteen to eighteen Hotchkiss 5-barrel revolving guns. They fired a shell weighing about to a range of about. They had a rate of fire of about 30 rounds per minute.

Armor

The Colbert-class ships had a complete wrought iron waterline belt that was thick amidships and tapered to at the stern. It was backed by of wood. The sides of the battery itself were armored with of wrought iron, backed by of wood, and the ends of the battery were closed by transverse armored bulkheads thick, backed by of wood. The barbettes were unarmored, but the deck was thick.

Service

Trident, named after the weapon that symbolized mastery of the seas, was laid down in April 1870 in Toulon and launched on 9 November 1876. While the exact reason for such prolonged construction time is not known, it is believed that reduction of the French Navy's budget after the Franco-Prussian War of 1870–71 and out-of-date work practices in French dockyards were likely causes. The ship was completed on 1 November 1878 and became the flagship of the second-in-command of the Mediterranean Squadron the following month. Trident, together with her sister ship, bombarded the Tunisian port of Sfax on 15–16 July 1881 as the French occupied Tunisia. She was disarmed and placed in reserve in 1886–89, but was recommissioned on 17 February 1889 and resumed her role as flagship until she was again placed in reserve in 1894. The ship served as a gunnery training ship until she was condemned on 5 March 1900. Trident was renamed Var in 1904 and was sold for scrap five years later.
