to 387–405 officers and enlisted men. The ship's propulsion system consisted of a pair of triple-expansion steam engines driving two screw propellers. Steam was provided by eight coal-burning fire-tube boilers that were ducted into two funnels. Her machinery was rated to produce for a top speed of . She had a cruising radius of at . The ship was armed with a main battery of four 28-caliber guns and a secondary battery of six 30-cal. guns. All of these guns were placed in individual pivot mounts; the 164.7 mm guns were in sponsons located fore and aft, with two guns per broadside. Four of the 138.6 mm guns were in sponsons between the 164.7 mm guns, one was in an embrasure in the forecastle and the last was in a swivel mount on the stern. For close-range defense against torpedo boats, she carried a pair of 9-pounder guns, six 3-pounder Hotchkiss guns, and eight Hotchkiss revolver cannon. She was also armed with five torpedo tubes in her hull above the waterline. Armor protection consisted of a curved armor deck that was thick, along with plating on the conning tower. The main and secondary guns received thick gun shields. Modifications In 1893–1894, Jean Bart was rearmed with M1884 quick-firing guns for her main battery; her secondary 138.6 mm guns were partially replaced: the bow and forward pair of broadside guns were replaced with M1884 versions while the remainder remained the M1881 version but converted to quick firing. During another refit in 1896–1897, the ship's military masts were shortened to reduce topweight, with light pole masts placed atop the shortened masts. Her bow torpedo tubes were removed at this time as well. A third modernization in 1903–1905 saw the ship re-boilered with twelve Niclausse boilers and her light armament was revised to two 65 mm guns and ten 47 mm guns. Service history The contract for Jean Bart was awarded to the shipyard in Rochefort on 18 September 1886 and the order for her engines was placed on 19 November with Indret. She was placed on the navy's list in January 1887, and work on Jean Bart began with her keel laying in September 1887. She was launched on 24 October 1889 and was commissioned to begin sea trials on 5 March 1891. Her initial tests were approved on 8 October, and ten days later she departed for Toulon, where further trials
