Italian destroyer Carlo Mirabello

The ships were designed as scout cruisers (esploratori), essentially enlarged versions of contemporary destroyers.[1] They had an overall length of 103.75 meters (340 ft 5 in), a beam of 9.74 meters (31 ft 11 in) and a mean draft of 3.3 meters (10 ft 10 in).[2] They displaced 1,784 tonnes (1,756 long tons) at standard load, and 2,040 tonnes (2,010 long tons) at deep load. Their complement was 8 officers and 161 enlisted men.[3]

The Mirabellos were powered by two Parsons geared steam turbines, each driving one propeller shaft using steam supplied by four Yarrow boilers. The turbines were rated at 44,000 shaft horsepower (33,000 kW) for a speed of 35 knots (65 km/h; 40 mph) and Carlo Mirabello reached a speed of 33.74 knots (62.49 km/h; 38.83 mph) from 44,026 shp (32,830 kW) during her sea trials.[2] The ships carried enough fuel oil to give them a range of 2,300 nautical miles (4,300 km; 2,600 mi) at a speed of 12 knots (22 km/h; 14 mph).[3]

Their main battery consisted of eight Cannone da 102 mm (4 in)/35 S Modello 1914 guns in single mounts protected by gun shields, one each fore and aft of the superstructure on the centerline and the remaining guns positioned on the broadside amidships.[4] Carlo Mirabello exchanged a Cannone da 152 mm (6 in)/40 A Modello 1891 for the forward 102 mm gun; Carlo Mirabello received hers in 1917. The gun proved to be too heavy for the ships and its rate of fire was too slow. Anti-aircraft (AA) defense for the Mirabello-class ships was provided by a pair of 40-caliber Cannone da 76 mm (3 in)/40 Modello 1916 AA guns in single mounts.[2] They were equipped with four 450-millimeter (17.7 in) torpedo tubes in two twin mounts, one on each broadside.[4] The ship could also carry 100 mines.[2]
