Folgore-class destroyer. The Folgore class were a group of four destroyers built for the  (Royal Italian Navy) in the 1930s. None of the ships survived World War II.

Design and description
The Folgore-class destroyers were extremely similar to the preceding , although their beam was reduced in an unsuccessful attempt to improve their speed over that achieved by the earlier ships. The Folgores had an overall length of , a beam of  and a mean draft of  and  at deep load. They displaced  at standard load, and  at deep load. Their complement during wartime was 185 officers and enlisted men.

The Folgores were powered by two Belluzzo geared steam turbines, each driving one propeller shaft using steam supplied by three Thornycroft boilers. The turbines were designed to produce  and a speed of  in service, although the ships reached speeds of  during their sea trials while lightly loaded. They carried enough fuel oil to give them a range of  at a speed of .

Their main battery consisted of four 50-caliber Cannone da /50 A Modello 1926 guns in two twin-gun turrets, one each fore and aft of the superstructure. Anti-aircraft (AA) defense for the Folgore-class ships was provided by a pair of 39-caliber Cannone da /39 AA guns in single mounts amidships and a pair of twin-gun mounts for Breda  Modello 1931 machine guns. They were equipped with six  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 Folgores could carry 52 mines.

Turkish Ships

Four similar ships were built in Italy for the Turkish Navy:
 The s were similar to the Italian ships but fitted with two funnels. These ships were built by Cantiere navale di Riva Trigoso.
 The s were altered to have four single guns rather than two twin guns and were lengthened to compensate. These ships were built by Ansaldo in Genoa.
