Maestrale-class

The Maestrale class is a series of eight frigates constructed for the Italian Navy between 1978 and 1982. Developed by Fincantieri at the Riva Trigoso and Muggiano shipyards, the design utilized technology and experience from the preceding Lupo class. The class entered service starting in 1982 and was eventually succeeded by the Bergamini class.

The ships were designed for primary anti-submarine warfare (ASW) operations while maintaining multi-role capabilities for anti-surface and anti-air engagement. The design features a larger hull and displacement than the Lupo class, incorporating a continuous superstructure constructed from light alloys. The layout includes a single funnel and two pyramid masts of varying heights. Propulsion is provided by a combined diesel or gas (CODOG) system, utilizing gas turbines for high-speed transit and diesel engines for cruising.

The armament configuration consists of a main deck gun, surface-to-air missiles, and anti-ship missiles. Close-in weapon systems (CIWS) and machine guns provide point defense. For anti-submarine tasks, the vessels are equipped with both heavy and light torpedo launchers, supported by hull-mounted and variable depth sonar systems. The aviation facilities include a flight deck and a double hangar capable of housing two helicopters. Electronic systems include surface and air surveillance radars, fire control radars, and an integrated command and control system. Defensive measures consist of radio interceptors, jammers, and decoy rocket launchers, along with noise-suppression systems and a towed acoustic torpedo defense. The placement of the double hangar results in the concentration of weapon systems on the foredeck and midships.

The Italian Navy operated all eight vessels of the class, deploying them in domestic operations and international missions under NATO and United Nations mandates. Modernization efforts occurred in 2005, which included the installation of minor close-defense weaponry. Decommissioning of the class began in 2015. Beyond Italian service, the class has been the subject of export interest and secondary market sales. Indonesia signed a contract in 2021 to acquire and modernize two retired units. Ecuador entered negotiations for two vessels in 2024 as replacements for older assets. The Philippines previously evaluated the class but opted for new-build vessels.
