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]
