The Maestrale class is a class of frigates of the Italian Navy. The class is composed of eight vessels, all of which were built by Fincantieri S.p.A., Riva Trigoso, except for Grecale, which was built by Fincantieri S.p.A. – Muggiano, La Spezia.

The Maestrale-class frigates were primarily designed for anti-submarine warfare (ASW), however the ships are highly flexible so they are also capable of anti-air and anti-surface operations. Ships of this class have been widely used in various international missions, either under NATO or UN flag, and during normal operations of the Italian Navy.

The first of these ships entered in service in early 1982. The rest of the fleet was launched over the next three years. The ships of the Maestrale class will be replaced by the Bergamini class.^[3]
