The French protected cruiser Jean Bart, built in the late 1880s and early 1890s, was a significant vessel of the Jean Bart class, designed under the influence of the Jeune École doctrine. She measured 105 meters (344 ft 6 in) in length between perpendiculars, with a beam of 12.98 meters (42 ft 7 in) and a draft ranging from 6.10 to 6.45 meters (20 to 21 ft 2 in). Displacing approximately 4,044 long tons (4,109 tonnes), she had a crew complement of 387 to 405 officers and men during her operational life. Jean Bart’s propulsion system comprised two triple-expansion steam engines, powered by eight coal-fired fire-tube boilers, which drove two screw propellers. Her machinery produced around 8,000 indicated horsepower, allowing her to reach a top speed of approximately 19.5 knots (36.1 km/h; 22.4 mph). Her cruising radius was about 3,200 nautical miles (5,900 km; 3,700 miles) at 10 knots. Armament included a main battery of four 164.7 mm (6.48 in) 28-caliber guns and a secondary battery of six 138.6 mm (5.46 in) 30-caliber guns, all mounted in individual pivot mounts, with guns positioned in sponsons fore and aft, and on the broadside. She also carried smaller weapons for close-range defense, including two 65 mm (2.6 in) guns, six 47 mm (1.9 in) guns, and eight 37 mm Hotchkiss revolver cannons. Her offensive capabilities were complemented by five 356 mm (14 in) torpedo tubes above the waterline. Her armor consisted of a curved deck 40 to 90 mm (1.6 to 3.5 in) thick and 80 mm (3.1 in) armor on the conning tower, with gun shields of 54 mm (2.1 in). Throughout her career, Jean Bart underwent multiple modernizations, including rearming with quick-firing guns and replacing boilers with Niclausse water-tube boilers, which improved her performance to 20 knots. She served in various roles, including deployments to the Mediterranean, Northern Squadron, and in Southeast Asia during the Boxer Uprising. Her operational history included participation in training exercises, colonial stationing, and diplomatic visits, such as the 1893 voyage to the United States. Tragically, her service ended when she ran aground off the coast of Spanish Sahara in 1907 during heavy fog. Despite attempts to free her, the hull broke in half, and she was wrecked. Her wreck was sold for salvage, marking the end of her distinguished career and embodying the transitional period of naval technology at the turn of the 20th century.
