Maestrale class frigates primary task is Anti-Submarine Warfare (ASW),
however their weapons and systems provides them with a high degree of
flexibility which makes them capable warships in Anti-Surface (ASuW)
and Anti-Air (AAW) warfare roles.
All eight vessels of the class were built by Fincantieri S.p. A, Riva
Trigoso, except for Grecale, which was built by Fincantieri S.p.A. -
Muggiano, La Spezia.
Two vessels from
the class will be modernized and transfered to the Philippine Navy in
2013 following a deal to be signed in 2012.
Philippine Navy Deep Water Patrol Vessel: On 2 August
2012 it was announcement that the Philippine government entered negotiations
with the Italian government for purchase of two Maestrale class frigates
for the Philippine Navy Deep Water Patrol Vessel. The vessels will undergo
refurbishing and likely see their systems and weapons upgraded and modernized
before being transfered.
subdivision of the hull is made up of fifteen watertight compartments
and the buoyancy is ensured even with three adjacent compartments flooded.
The platform stability is ensured by a pair of fixed stabilizing fins
able to reduce roll from 30 ° to 3 ° at a speed of 18 knots.
The design is an enlarged version of the Lupo, with better sea going
capabilities and hangar space for two helicopters at the expense of
four antiship missiles and a lower maximum speed.
Many solutions have been applied for vibration and noise reduction to
reduce noise radiated into the sea in order which is essential for an
ASW class of vessel.
