Design and description

edit

The Oriani-class destroyers were slightly improved versions of the preceding Maestrale class.[1] They had a length between perpendiculars of 101.6 meters (333 ft 4 in)[2] and an overall length of 106.7 meters (350 ft 1 in). The ships had a beam of 10.15 meters (33 ft 4 in) and a mean draft of 3.15 meters (10 ft 4 in) and 4.3 meters (14 ft 1 in) at deep load.[3] They displaced 1,700–1,750 metric tons (1,670–1,720 long tons) at normal load, and 2,400–2,450 metric tons (2,360–2,410 long tons) at deep load.[4] Their complement during wartime was 206 officers and enlisted men.[2]

The Orianis were powered by two Parsons geared steam turbines, each driving one propeller shaft using steam supplied by three Thornycroft boilers.[2] Designed for a maximum output of 48,000 shaft horsepower (36,000 kW) and a speed of 32–33 knots (59–61 km/h; 37–38 mph) in service, the ships reached speeds of 38–39 knots (70–72 km/h; 44–45 mph) during their sea trials while lightly loaded. They carried enough fuel oil to give them a range of 2,600–2,800 nautical miles (4,800–5,200 km; 3,000–3,200 mi) at a speed of 18 knots (33 km/h; 21 mph) and 690 nmi (1,280 km; 790 mi) at a speed of 33 knots (61 km/h; 38 mph).[4]

Their main battery consisted of four 50-caliber 120-millimeter (4.7 in) guns in two twin-gun turrets, one each fore and aft of the superstructure.[5] Amidships were a pair of 15-caliber 120-millimeter star shell guns. Anti-aircraft (AA) defense for the Oriani-class ships was provided by four 13.2-millimeter (0.52 in) machine guns. The ships were equipped with six 533-millimeter (21 in) torpedo tubes in two triple mounts amidships. Although they were not provided with a sonar system for anti-submarine work, they were fitted with a pair of depth charge throwers.[4] The ships could carry 56 mines.[5]
