The Italian cruiser Pisa was the lead vessel of her class of two armored cruisers built for the Royal Italian Navy in the early 20th century. Laid down on February 20, 1905, at the Orlando shipyard in Livorno, she was launched on September 15, 1907, and completed by September 1, 1909. The ship measured approximately 140.5 meters (460 ft 11 in) in overall length, with a beam of 21 meters (68 ft 11 in) and a draft of 7.1 meters (23 ft 4 in). Displacing around 9,832 metric tons at normal load and up to 10,600 tons at deep load, Pisa featured a crew of about 32 officers and 652 to 655 enlisted men. Propelled by two vertical triple-expansion steam engines powered by 22 Belleville boilers, Pisa had a maximum speed exceeding 23 knots, reaching 23.47 knots during sea trials with 20,808 indicated horsepower. Her cruising range was approximately 2,500 nautical miles at 12 knots. Her armament comprised four 254 mm (10 in) guns in twin-gun turrets fore and aft, complemented by eight 190 mm (7.5 in) guns in four twin turrets amidships. For defense against smaller vessels, Pisa carried 16 quick-firing 76 mm guns and eight 47 mm guns. She also mounted three submerged 450 mm torpedo tubes. During World War I, her smaller-caliber guns were upgraded to twenty 76/40 mm guns, including six anti-aircraft weapons. The ship’s armor belt was 200 mm (7.9 in) amidships, tapering to 90 mm (3.5 in) at the bow and stern. The armored deck was 51 mm (2 in) thick, with the conning tower protected by 180 mm (7.1 in) of armor. Guarding her main guns, the turrets had armor thicknesses of 160 mm (6.3 in) for the 254 mm turrets and 140 mm (5.5 in) for the 190 mm turrets. Pisa's service history includes participation in the Italo-Turkish War of 1911–1912, where she supported landings and shelled Ottoman fortifications, notably at Derna, Libya, and Rhodes. During WWI, her activities were constrained by the threat of Austrian submarines, but she did partake in the bombardment of Durazzo in late 1918. After the war, Pisa served as a training ship from 1921, with modifications for aircraft operations in 1925. She was stricken from the naval register in 1937 and subsequently scrapped, marking the end of her maritime service.
