The Andrea Doria was an Italian ironclad battleship constructed during the late 19th century, representing the final vessel of the Ruggiero di Lauria class. Built at La Spezia Navy Yard, her construction commenced on January 7, 1882, and was completed on May 16, 1891, after an extensive nine-and-a-half-year build period. She measured 105.9 meters (347 feet 5 inches) in length overall, with a beam of 19.84 meters (65 feet 1 inch) and an average draft of 8.29 meters (27 feet 2 inches). Displacing approximately 9,886 long tons (10,045 tons) normally, and up to 11,027 long tons (11,204 tons) at full load, she featured a steel hull protected by 451 mm (17.75 inches) of belt armor and 76 mm (3 inches) of armored deck. Her superstructure was modest, with a small conning tower and a single heavy military mast amidships. Propulsion was provided by two compound steam engines, each driving a screw propeller, powered by eight coal-fired cylindrical boilers venting through two funnels. Her engines produced a top speed of 16.1 knots (29.8 km/h) and a cruising range of 2,800 nautical miles at 10 knots. The armament included four 432 mm (17-inch) main guns mounted in two pairs en echelon in a central barbette, supplemented by secondary guns: two 152 mm (6-inch) guns, and four 120 mm (5-inch) guns. She also carried five submerged 356 mm (14-inch) torpedo tubes. Her armor protection was substantial, with the belt armor at 451 mm thick, and the conning tower armored with 249 mm steel plates. Her armament and armor reflected the design priorities of the period, although rapid advances in naval technology quickly rendered her obsolete. Andrea Doria’s service primarily involved training exercises and fleet maneuvers, with limited active combat role. She served in various fleet divisions, participated in naval reviews, and made visits to the United Kingdom and Germany. Stricken from the naval register in 1911, she was repurposed as a depot ship, then as a floating oil tank after World War I, until she was finally scrapped in 1929. Her construction and service highlight the transitional period of naval design from ironclads to pre-dreadnought battleships.
