Emanuele Pessagno was one of a dozen Navigatori-class destroyers built for the Regia Marina (Royal Italian Navy) in the late 1920s. Completed in 1930, she served in World War II.

Design and description

The Navigatori-class destroyers were designed to counter the large French destroyers of the Jaguar and Guépard classes.^[1] They had an overall length of 107.3 meters (352 ft), a beam of 10.2 meters (33 ft 6 in) and a mean draft of 3.5 meters (11 ft 6 in).^[2] They displaced 1,900 metric tons (1,900 long tons) at standard load, and 2,580 metric tons (2,540 long tons) at deep load. Their complement during wartime was 222–225 officers and enlisted men.^[3]

The Navigatoris were powered by two Tosi geared steam turbines, each driving one propeller shaft using steam supplied by four Odero-Terni-Orlando water-tube boilers. The turbines were designed to produce 55,000 shaft horsepower (41,000 kW)^[3] and a speed of 32 knots (59 km/h; 37 mph) in service, although the ships reached speeds of 38–41 knots (70–76 km/h; 44–47 mph) during their sea trials while lightly loaded.^[4] They carried enough fuel oil to give them a range of 3,800 nautical miles (7,000 km; 4,400 mi) at a speed of 18 knots (33 km/h; 21 mph).^[3]

Their main battery consisted of six 120-millimeter (4.7 in) guns in three twin-gun turrets, one each fore and aft of the superstructure and the third amidships.^[5] Anti-aircraft (AA) defense for the Navigatori-class ships was provided by a pair of 40-millimeter (1.6 in) AA guns in single mounts abreast the forward funnel and a pair of twin-gun mounts for 13.2-millimeter (0.52 in) machine guns. They were equipped with six 533-millimeter (21 in) torpedo tubes in two triple mounts amidships. The Navigatoris could carry 86–104 mines.^[4]

Construction and career

Emanuele Pessagno was laid down by Cantieri Navali Riuniti at their Ancona shipyard on 9 October 1927, launched on 12 August 1929 and commissioned on 10 March 1930.^[2]
