Bergamini class (FREMM) frigates of the Italian Navy
Italian Navy Bergamini class FREMM variants in formation
Bergamini class is the Italian variant of the Frigate European Multi-Mission (FREMM) class, a class of frigates designed by the French DCNS and the Italian Ficantieri in a joint program to replace the existing destroyers and frigates within the French and Italian navies. As we mentioned in the article about the French variant, the
Aquitaine class, the frigates between the two navies share some general characteristics, weapons and systems but also have several differences in the equipment related to propulsion system, electronic equipment and weapons following the different requirements of both navies. The Italian Navy (Marina Militare Italiana) is building two variants/versions of
Bergamini class frigates, one for ASW (Anti-Submarine Warfare) role and one for General Purpose (GP) role; in this article both variants will be described. Italian Navy aims to replace the eight (8) frigates of
Maestrale class and the four (4) frigates of the
Lupo class with ten (10) Bergamini class which are devided in three variants including the AAW for the last pair of ships. Bergamini class is a class of stealth frigates with advanced Anti-Aircraft Warfare (AAW) capabilities featuring a common sensor and weapons package based on MBDA’s SAAM-ESD (Extended Self-Defence) area defence system, including Selex ES MFRA EMPAR-derived C-band multifunction radar with active phased array antenna and Aster 15 and Aster 30 missiles in A50silos. EMPAR MFRA is an evolved version of the EMPAR radar (embarked on Orizzonte class destroyers and the Cavour aircraft carrier). In addition to that, each variant is specialized in a specific role, GP or ASW, with increased equipment to perform this particular role.

The general characteristics of the class is a displacement of 6,900tons, length of 144.6m, beam of about 20m, maximum speed of 30knots and range of 6,700n.m. with a cruising speed of 15knots. The ship has a crew of 145 persons (GP variant) or 147 persons (ASW variant) while 9 more persons are added to the crew for a second helicopter on board. The vessels can accomodate up to 200 people in total. Each vessel can accommodate one or two NH90 ASW helicopters or one NH90 and one EH101 helicopters, and/or UAVs Moreover, each ship carries two Rigid-Hulled Inflatable Boats (RHIB)s for commando operations (one of 7m at the right side, starboard, and one of 11m at the left side, port) while the GP variant carries one more RHIB of 11m in the stern launching ramp instead of a Variable Depth Sonar (VDS) in ASW variant.

The frigates have one main gun on the bow deck which is either the
OTO Melara (now Leonardo) Super Rapido 76mm/62cal gun on the ASW variant or the
OTO Melara 127mm/64cal Lightweight (LW) on the GP variant. Each vessel has a secondary OTO Melara Super Rapido 76mm/62cal gun installed on the starboard roof of the helicopter hangar. The 76mm guns are part of the STRALES system which consists of the naval gun, a Radio Frequency Guidance System with the electronic control unit and the DART ammunition. STRALES is an all-weather system that was designed to engage and to destroy multiple manoeuvring targets with the use of guidance ammunition for increased accuracy and therefore lethality. STRALES includes a Radio Frequency Guidance System provided with a mechanical frame to be connected to the gun-mount structure. A gun shield is provided with a watertight cover which can be automatically removed to deploy the guidance antenna; once actual target position and stabilisation data are available, STRALES operates as a stand alone system.

The DART projectile is equipped with the new DART microwave programmable multifunction fuse. The effective operating range is greater than 8km while the maneuverability is higher than.. 40g! A new Multiple-Feeding (MF) ammunition loading system for the 76/62 mm is also available as a separate kit which is able to select any ammunition contained in the branches regardless of its position (typically, DART and standard ammo). The gun can intercept air and surface targets at a distance of 16 km (6km the effective range against anti-ship missiles) unleashing 120 rounds per minute weighting greater than 6kg each. The gun has excellent performance in any kind of role, such as air defence, anti surface, anti-missile and shore bombardment role. It is claimed by OTO Melara that these guns can engage 4 missiles before they reach the ship.

The
OTO Melara 127mm/64cal Lightweight (LW) on the GP variant is part of the VULCANO system which consists of four key sub-systems: the medium caliber 127/64 LW Gun assembly, the Automated Ammunition Handling System, the Naval Fire Control Support and the VULCANO family of ammunition. The system is intended for surface fire and naval gunfire support as main role and anti-aircraft fire as secondary role. The 127/64 LW - VULCANO is equipped with a modular feeding magazine, composed by 4 drums with 14 ready to fire ammunition each (56 in total), reloadable during firing, and highly flexible in terms of selection of ammunition, independently from their position in the drums. Ammunition flow is reversible as rounds can be downloaded automatically. The 127mm VULCANO ammunition family, is composed by Ballistic Extended Range (BER) and Guided Long Range (GLR) ammunition with different multifunctional fuses, sensor and final guidance that extend the range of the gun up to 100km. The rate of fire is 32rds per minute. General Purpose FREMMs are getting the highly Automated Ammunition Handling System for the 127/64 mm gun, which holds 350 127mm shells in addition to the 56 in the four reload drums of the gun turret.

The frigates have also two
OTO Melara Oerlikon KBA 25mm/80cal guns which are installed one to port and one to starboard. The guns are stabilized, electric servo-drive assisted, while a weapon control is featured in order to allow the gunner to remain steady at any barrel elevation, laying the gun with the maximum accuracy even against targets at maximum elevation. A conventional aiming system is fitted to the mount, but also an IR sight with integrated ballistic reticule is available. The rate of fire is about 650 rounds per minute and the effective range for aerial targets is about 2,000m. The gun has two 126-round boxes on each side of it.

The vLS behind the 5in gun
Behind the front gun and forward of the bridge, it is installed a DCNS Sylver A50 VLS with 16 cells (two VLS modules) for MBDA
Aster 15 anti-aircraft missiles for local and area defence (medium range) and Aster 30 missiles that provide long range interception capability for area defence (see the
video for Sylver VLS). Similarly with the French FREMM frigates, the space located backwards of the current silos allows for 16 more missiles, and specifically two A70 silos for land-attack/cruise missiles in the future. But as of today the Italian Navy is using that space for the crew accommodation. Both Aster 15 and 30 missiles featuring the same terminal dart. The Aster missiles are autonomously guided with a maximum range of greater than 30km for Aster 15 and a speed of higher than Mach 3 and a range of 100-120km and Mach 4.5 for Aster 30 that has two-stage propulsion system . The missile provides protection to the vessel against a full spectrum of air threats such as anti-shipping missile including sea-skimming and high diver missiles, supersonic and subsonic missiles, anti-radiation missiles UAV and aircrafts (see
video) with a very high single shot probability. ASTER’s terminal dart is a lightweight, highly manoeuvring and agile missile equipped with a high-performance active RF seeker with capability against stealthy targets. Thanks to the unique combination of aerodynamic control and direct thrust vector control called “PIF-PAF, the missile is capable of high g manoeuvres. Together, these features give ASTER an unmatched hit-to-kill capability. The system has an extremely quick reaction time with high rate of fire and it provides full coverage under any kind of weather.

The frigates carry the
MBDA Otomat/Teseo Mk2A block IV guided anti-ship missile in four single launchers amidships while there is provision for four more (packed in quads). The missile has a range of up to 180km, a high subsonic speed Mach 0.9 and carries a warhead of 210kg capable piercing up to 80mm of steel. The warhead is designed to explode inside the ship with the force of the explosion directed to the bottom of the target ship. Capable of ranges from 6-180km in all directions, the system relies on powerful mission planning (3D way-points, terminal sea skimming profile, simultaneous attack from different directions). Target data is derived from the ship's Command System or taken directly from the ship's surface search radar. Mission Planning allows the selection of different firing modes (such as Fire and Forget or midcourse guided) and of specific trajectories and evasive manoeuvres. Cruise and approach phases may be either fully inertial or partially guided from the launch ship through a radio-link. Mid course re-vectoring from a co-operating ship or helicopter is also possible. The excellent capabilities of the missile (short reaction time, Fire and Forget, INS/GPS navigation, high target selection, ECCM and anti-CIWS manoeuvres, warhead lethality with no collateral damage) allow the system to operate effectively in littoral warfare environments, as well as in blue waters. The terminal attack phase is based upon an autonomous terminal guidance using an active homing head with improved target selection capabilities in complex scenarios. It should be mentioned that Otomat is one of the most powerful of all modern western anti-ship missiles having a mid course data-link and land attack capability.
