Sardegna

Sardegna was 411 feet 9 inches (125.5 m) between perpendiculars and 428 feet 10.5 inches (130.7 m) long overall. She had a beam of 76 feet 10.5 inches (23.4 m) and a draft of 29 feet (8.8 m). Normally she displaced 13,641 long tons (13,860 t) and displaced 15,426 long tons (15,674 t) at full load. She was built with a ram bow.[1]

Propulsion[edit]

Sardegna was the first Italian warship fitted with two three-cylinder vertical triple expansion steam engines with a total designed output of 22,800 indicated horsepower (17,002 kW). Eighteen cylindrical boilers provided steam to the engines. On trials, the ship had a top speed of 20.3 knots (37.6 km/h; 23.4 mph). She carried enough coal to give her a range of 4,000–6,000 nautical miles (7,408–11,112 km) at 10 knots (19 km/h; 12 mph). She had three funnels, but, unusually, the two forward funnels were side-by-side.[1]

Armament[edit]

Sardegna's main armament consisted of two pairs of breech-loading British BL 13.5-inch (343 mm) Mk I–IV 30-caliber guns mounted in twin barbettes fore and aft. These guns had a maximum elevation of 13.5° and could depress to -3°. They fired a 1,250-pound (570 kg) shell at a muzzle velocity of about 2,016 ft/s (614 m/s) to a range of about 11,950 yards (10,930 m) at maximum elevation. They had a rate of fire about 2–3 minutes per round.[2]

The eight 6-inch (152 mm) 40-caliber guns were mounted on pivot mounts on the upper deck. They were protected by gun shields 2 inches (51 mm) thick. The anti-torpedo boat armament consisted of sixteen 4.7-inch (120 mm) 40-caliber guns. Twelve of these were in casemates on the main deck and four were mounted in the fore and aft superstructures, protected by gun shields. Twenty 57-millimeter (2.2 in) six-pounder and ten 37-millimeter (1.5 in) one-pounder guns were mounted in the superstructure. Sardegna carried five 17.7-inch (450 mm) torpedo tubes, all above water.[1]

Armor[edit]

Sardegna's steel armor was made by the French company Schneider et Cie. The side of the hull between the barbettes was completely protected with a maximum thickness of 4 inches (102 mm) of armor. The barbettes were 13.75 inches (349 mm) thick and she was the only ship of her class to receive 4-inch gun shields for her main armament. The conning tower had 11.8 inches (300 mm) walls. The armor deck was 3 inches (76 mm) thick.[1]

Service[edit]

Sardegna was named after the island of Sardinia. She was built by the La Spezia Naval Shipyard. She was laid down on 24 October 1885, launched on 20 September 1890, and completed on 16 February 1895. She participated in the Italo-Turkish War, where she used an airplane to spot for her guns.[3] She was stricken on 4 January 1923.[1]
