Italian destroyer Carlo Mirabello

Carlo Mirabello was one of three Mirabello-class destroyers built for the Regia Marina (Royal Italian Navy) during World War I.

Design and description
The ships were designed as scout cruisers (esploratori), essentially enlarged versions of contemporary destroyers. They had an overall length of 103.75 m, a beam of 9.74 m and a mean draft of 3.3 m. They displaced 1784 t at standard load, and 2040 t at deep load. Their complement was 8 officers and 161 enlisted men.

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 44000 shp for a speed of 35 kn and Carlo Mirabello reached a speed of 33.74 kn from 44026 shp during her sea trials. The ships carried enough fuel oil to give them a range of 2300 nmi at a speed of 12 kn.

Their main battery consisted of eight Cannone da 102 mm/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. Carlo Mirabello exchanged a Cannone da 152 mm/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/40 Modello 1916 AA guns in single mounts. They were equipped with four 450 mm torpedo tubes in two twin mounts, one on each broadside. The ship could also carry 100 mines.

Modifications
The 152 mm gun proved to be too heavy for the ships and its rate of fire was too slow so it was replaced when the Mirabello-class ships were rearmed with eight 45-caliber Cannone da 102/45 S, A Modello 1917 guns arranged as per Carlo Mirabello's original configuration in 1919. The 76 mm guns were replaced by a pair of 39-caliber Cannone da 40 mm/39 AA guns in single mounts in 1920–1922.
