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 ''Folgore''s were powered by two Belluzzo geared steam turbine

.[Fraccaroli, p. 53] 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

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.
