Maestrale-class destroyer

The Maestrale class were a group of destroyers built for the Regia Marina (Royal Italian Navy) and served in World War II. They formed the basis for subsequent Italian destroyer designs; the Oriani and Soldati classes.

The Maestrale-class destroyers were a completely new design intended to rectify the stability problems of the preceding Folgore class. They had a length between perpendiculars of 101.6 meters (333 ft 4 in) and an overall length of 106.7 meters (350 ft 1 in). The ships had a beam of 10.15 meters (33 ft 4 in) and a mean draft of 3.31 meters (10 ft 10 in) and 4.3 meters (14 ft 1 in) at deep load. They displaced 1,640 metric tons (1,610 long tons) at normal load, and 2,243 metric tons (2,208 long tons) at deep load. Their complement during wartime was 190 officers and enlisted men.

The Maestrales were powered by two Parsons geared steam turbines, each driving one propeller shaft using steam supplied by a trio of three-drum boilers. The turbines were designed to produce 44,000 shaft horsepower (33,000 kW) and a speed of 32–33 knots (59–61 km/h; 37–38 mph) in service, although they reached speeds of 38–39 knots (70–72 km/h; 44–45 mph) during their sea trials while lightly loaded. The ships carried enough fuel oil to give them a range of 2,600–2,800 nautical miles (4,800–5,200 km; 3,000–3,200 mi) at a speed of 18 knots (33 km/h; 21 mph) and 690 nmi (1,280 km; 790 mi) at a speed of 33 knots (61 km/h; 38 mph).

Their main battery consisted of four 50-caliber 120-millimeter (4.7 in) guns in two twin-gun turrets, one each fore and aft of the superstructure. Amidships were a pair of 15-caliber 120-millimeter star shell guns. Anti-aircraft (AA) defense for the Maestrale-class ships was provided by four 13.2-millimeter (0.52 in) machine guns. They were equipped with six 533-millimeter (21 in) torpedo tubes in two triple mounts amidships. Although the ships were not provided with a sonar system for anti-submarine work, they were fitted with a pair of depth charge throwers. The Maestrales could carry 56 mines.
