Andrea Doria was an

ironclad battleship built for the Italian Regia Marina (Royal Navy) in the 1880s and 1890s. Named for the 16th-century Genoese admiral Andrea Doria, she was the third and final ship of the Ruggiero di Lauria class. The ship was armed with a main battery of four 432 mm (17 in) guns, was protected with 451 mm (17.75 in) thick belt armor, and was capable of a top speed of 17 knots
(31 km/h; 20 mph).

The ship's construction period was very lengthy, beginning in August 1881 and completing in February 1888. She was quickly rendered obsolescent by the new

naval register in 1911 and used as a depot ship until Italy entered World War I in 1915. The ship was renamed GR 104 and employed as a guard ship in Brindisi
. She was converted into a floating oil tank after the war and was eventually broken up for scrap in 1929.

Design

Line-drawing of the Ruggiero di Lauria class

Andrea Doria was 105.9 meters (347 ft 5 in)

amidships. She had a crew of 507–509 officers and men.[1]

Her propulsion system consisted of a pair of

screw propeller. Steam was supplied by eight coal-fired, cylindrical fire-tube boilers that were vented through a pair of widely spaced funnels at the ends of the hurricane deck. Her engines produced a top speed of 16.1 knots (29.8 km/h; 18.5 mph) at 10,500 indicated horsepower (7,800 kW). She could steam for 2,800 nautical miles (5,200 km; 3,200 mi) at a speed of 10 knots (19 km/h; 12 mph).[1]

Andrea Doria was armed with a

bow and the other at the stern, and four 120 mm (5 in) 32-cal. guns; two of these were placed side by side behind the bow 152 mm gun, and the other two were mounted side by side on the aft superstructure. As was customary for capital ships of the period, she carried five 356 mm (14 in) torpedo tubes submerged in the hull.[1]

She was protected by steel armor; her belt armor was 451 mm (17.75 in) thick, and her armored deck was 76 mm (3 in) thick. The deck sloped downward at the sides to provide additional protection against incoming fire. Her conning tower was armored with 249 mm (9.8 in) of steel plate on the sides. The barbette had 361 mm (14.2 in) of steel armor.[1]

Service history

Andrea Doria was under construction for nine-and-a-half years. She was

Krupp armor—rapidly rendered older vessels like Andrea Doria obsolete.[2]

Andrea Doria served with the 2nd Division of the Active Squadron during the 1893 fleet maneuvers, along with the ironclad

In 1896, Andrea Doria served in the 2nd Division for the summer maneuvers, held in July. The Division also included her sister Francesco Morosini and the protected cruiser Giovanni Bausan. The 1st and 2nd Divisions of the Active Squadron were tasked with defending against a hostile fleet, simulated by older ships in reserve.[7] In 1899, Andrea Doria, Ruggiero di Lauria, Sicilia, and Sardegna took part in a naval review in Cagliari for the Italian King Umberto I, which included a French and British squadron as well.[8] That year, Andrea Doria and her two sisters served in the Active Squadron, which was kept in service for eight months of the year, with the remainder spent with reduced crews. The Squadron also included the ironclads Re Umberto, Sicilia, and Lepanto.[9] In 1900, Andrea Doria and her sisters were significantly modified and received a large number of small guns for defense against torpedo boats. These included a pair of 75 mm (3 in) guns, ten 57 mm (2.2 in) 40-caliber guns, twelve 37 mm (1.5 in) guns, five 37 mm revolver cannon, and two machine guns.[1]

In 1905, Ruggiero di Lauria and her two sisters were joined in the Reserve Squadron by the three

dreadnought battleship of the same name had just been completed[12]—and was transferred to Brindisi, where she served as a guard ship. Following the end of the war, she was converted into a floating oil tank; she served in this capacity until 1929, when she was broken up for scrap.[11]
