Design and description
The Folgore-class destroyers were essentially copies of the preceding Freccia class, although their beam was reduced in an unsuccessful attempt to improve their speed over that achieved by the earlier ships. [1] The Folgores had an overall length of 96.05 meters (315 ft 1 in), a beam of 9.2 meters (30 ft 2 in) and a mean draft of 3.3 meters (10 ft 10 in) [2] and 4.3 meters (14 ft 1 in) at deep load. [1] They displaced 1,238 metric tons (1,218 long tons ) at standard load, and 2,090 metric tons (2,060 long tons) at deep load. [3] Their complement during wartime was 185 officers and enlisted men. [4]
The Folgores were powered by two Belluzzo geared steam turbines, each driving one propeller shaft using steam supplied by three Thornycroft boilers. [4] The turbines were designed to produce 44,000 shaft horsepower (33,000 kW ) and a speed of 30 knots (56 km/h; 35 mph) in service, although 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 3,600 nautical miles (6,700 km; 4,100 mi) at a speed of 12 knots (22 km/h; 14 mph). [1]
Their main battery consisted of four 120-millimeter (4.7 in) guns in two twin-gun turrets, one each fore and aft of the superstructure. [3] Anti-aircraft (AA) defense for the Folgore-class ships was provided by a pair of 40-millimeter (1.6 in) AA guns in single mounts amidships and a pair of twin-gun mounts for 13.2-millimeter (0.52 in) machine guns. They were equipped with six 533-millimeter (21 in) torpedo tubes in two triple mounts amidships. Although the ships were not provided with a sonar system for anti-submarine work, they were fitted with a pair of depth charge throwers. [1] The Folgores could carry 52 mines. [3]
