The Andrea Doria was the lead battleship of her class, built for the Regia Marina (Royal Italian Navy). She was laid down in March 1912 at the La Spezia shipyard, launched in March 1913, and completed in March 1916. As the only ship of her class alongside her sister Duilio, Andrea Doria measured approximately 176 meters (577 feet) in length overall, with a beam of 28 meters (92 feet) and a draft of 9.4 meters (31 feet). Her displacement at full combat load reached around 24,729 metric tons. The ship featured a prominent forecastle deck extending over the first third of her hull, a small armored conning tower aft of her main gun turrets, and a superstructure with two tripod masts. Andrea Doria’s main armament consisted of thirteen 305 mm (12 in) guns mounted in three triple turrets and two twin turrets, complemented by a secondary battery of sixteen 152 mm (6 in) guns, and a variety of smaller caliber weapons including thirteen 76 mm guns, anti-aircraft guns, and submerged torpedo tubes. Her armor protection included a belt of 254 mm (10 in) steel, a main deck of 98 mm (3.9 in), and 280 mm (11 in) on her main turrets and conning tower, providing significant defensive strength. Powered by four Parsons steam turbines and eight oil-fired boilers, Andrea Doria could achieve a top speed of 21 knots, later increased to 26 knots following a comprehensive modernization between 1937 and 1940. During this refit, her length was extended to nearly 187 meters (613 feet), her displacement increased, and her machinery was upgraded to deliver 75,000 shp, boosting her speed and operational capabilities. Her armament was also modernized, with the main guns bored out to 320 mm (12.6 in) and her secondary guns replaced with new models, along with enhanced anti-aircraft defenses. Throughout her service, Andrea Doria saw limited combat but played notable roles in several key events. She participated in the suppression of the rebellion in Fiume in 1919, the Corfu incident in 1923, and various Mediterranean patrols and diplomatic visits. During World War II, she escorted convoys to Libya and engaged in the First Battle of Sirte in 1942. Interned in Malta after Italy’s capitulation in 1943, she survived the war and later served as a flagship and training ship until being decommissioned in 1956. Her extensive career underscores her importance in Italy’s naval history, reflecting advancements in battleship design and Italy’s maritime strategy through the first half of the 20th century.
