Italian destroyer Carlo Alberto Racchia  Carlo Alberto Racchia was one of three s built for the (Royal Italian Navy) during World War I. The ships were designed as scout cruisers ("esploratori"), essentially enlarged versions of contemporary destroyers. They had an overall length of , a beam of and a mean draft of . They displaced at standard load, and at deep load. Their complement was 8 officers and 161 enlisted men. The "Mirabello"s 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 for a speed of and "Carlo Alberto Racchia" reached a speed of from during her sea trials. The ships carried enough fuel oil to give them a range of at a speed of . "Carlo Alberto Racchia"s main battery consisted of a single Cannone da /40 A Modello 1891 gun forward of the superstructure. The gun was backed up by seven Cannone da /35 S Modello 1914 guns in single mounts protected by gun shields, one aft the superstructure and the remaining guns positioned on the broadside amidships. Anti-aircraft (AA) defense for the "Mirabello"-class ships was provided by a pair of Cannone da /40 Modello 1916 AA guns in single mounts. They were equipped with four torpedo tubes in two twin mounts, one on each broadside. "Carlo Alberto Racchia" also could carry 100 mines. The gun proved to be too heavy for the ships and its rate of fire was too slow so it was replaced when the ships were rearmed with eight Cannone da 102/45 S, A Modello 1917 guns arranged with single guns fore and aft of the superstructure and the other on the broadside. The 76 mm guns were replaced by a pair of Cannone da /39 AA guns in single mounts in 1920–1922. It is uncertain if "Carlo Alberto Racchia" received these guns before her loss.
