The French ironclad Richelieu was a wooden-hulled, central battery ironclad constructed for the French Navy in the early 1870s, designed by Henri Dupuy de Lôme as an improved version of the Océan-class. She measured 101.7 meters (333 ft 8 in) in overall length, with a beam of 17.4 meters (57 ft 1 in) and a maximum draft of 8.5 meters (27 ft 11 in). Displacing approximately 8,984 metric tons (8,842 long tons), Richelieu featured a low metacentric height of just over 1.5 feet (0.5 m), indicating a relatively low stability. The ship was powered by two horizontal return connecting rod compound steam engines, each driving a propeller, with eight oval boilers providing steam. During sea trials, her engines produced 4,600 indicated horsepower, enabling her to reach a speed of 13.2 knots. She carried 640 metric tons of coal, giving her an operational range of about 3,300 nautical miles at 10 knots. Originally square-rigged with three masts, she was later reduced to a schooner rig for sailing. Armament comprised a central battery of six 274-millimeter (10.8 in) guns in barbettes on the upper deck, with four 240-millimeter (9.4 in) guns mounted in the battery deck below. Additionally, she had one 240-millimeter gun in the forecastle and secondary armament of ten 120-millimeter (4.7 in) guns, later replaced by six 138-millimeter (5.4 in) guns. She was equipped with eight, then later ten, 37-millimeter Hotchkiss revolving guns, and late in her career, four 356-millimeter (14.0 in) torpedo tubes were added. The armor protection included a complete waterline belt of 220 millimeters (8.7 in) wrought iron, with sides and transverse bulkheads of 160 millimeters (6.3 in) of wrought iron, and a deck armored with 10 millimeters (0.4 in) of armor. Richelieu's construction began in 1869 at Toulon and she was launched in December 1873. Her prolonged construction period was likely due to financial constraints and outdated dockyard practices. She entered service in 1876 as the flagship of the Mediterranean Squadron, serving notably until 1886. In 1880, Richelieu caught fire in Toulon and was scuttled to prevent magazine explosions. She was salvaged, repaired, and returned to service, continuing as a flagship until 1886. She later served in reserve and flagship roles before being condemned in 1900. In 1911, while being towed to the Netherlands for scrapping, Richelieu was caught in a storm and cast loose, but she survived and was recovered near the Scilly Isles before being broken up in Amsterdam. Her service history underscores her importance as a notable example of French naval design during the late 19th century.
