Augusto Riboty was one of three Mirabello-class destroyers built for the Regia Marina (Royal Italian Navy) during World War I.
Design and description
[edit]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 Augusto Riboty reached a speed of 35.03 knots (64.88 km/h; 40.31 mph) from 38,962 shp (29,054 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]
Augusto Riboty's main battery consisted of a single Cannone da 152 mm (6 in)/40 A Modello 1891 gun forward of the superstructure. The gun was backed up by seven Cannone da 102 mm (4 in)/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.[4] Anti-aircraft (AA) defense for the Mirabello-class ships was provided by a pair of 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] Augusto Riboty could carry 120 mines, although her sisters could only handle 100.[2]
Modifications
[edit]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 40 mm (1.6 in)/39 AA guns in single mounts in 1920–1922.[2]
