The Sauro-class destroyers were enlarged and improved versions of the preceding Sella class.[1] They had an overall length of 90.16 meters (296 ft), a beam of 9.2 meters (30 ft 2 in) and a mean draft of 2.9 meters (9 ft 6 in). They displaced 1,058 metric tons (1,041 long tons) at standard load, and 1,600 metric tons (1,570 long tons) at deep load. Their complement was 8–10 officers and 146 enlisted men.[2]
The Sauros were powered by two Parsons geared steam turbines, each driving one propeller shaft using steam supplied by three Yarrow boilers.[1] The turbines were rated at 36,000 shaft horsepower (27,000 kW) for a speed of 31 knots (57 km/h; 36 mph) in service,[3] although Francesco Nullo reached a speed of 37 knots (69 km/h; 43 mph) from 45,000 shp (34,000 kW) during her sea trials while lightly loaded.[4] The ships carried enough fuel oil to give them a range of 2,600 nautical miles (4,800 km; 3,000 mi) at a speed of 14 knots (26 km/h; 16 mph).[1]
Their main battery consisted of four 120-millimeter (4.7 in) guns in two twin-gun turrets, one each fore and aft of the superstructure.[2] Anti-aircraft (AA) defense for the Sauro-class ships was provided by a pair of 40-millimeter (1.6 in) AA guns in single mounts amidships and a pair of 13.2-millimeter (0.52 in) machine guns. They were equipped with six 533-millimeter (21 in) torpedo tubes in two triple mounts amidships.[3] The Sauros could also carry 52 mines.[2]
Francesco Nullo was laid down by Cantieri navali del Quarnaro at their Fiume shipyard on 9 October 1924, launched on 14 November 1925 and commissioned on 15 April 1927.[1]
