The Italian Carlo Bergamini class warships were developed as a part of Franco-Italian FREMM multi-mission frigate program. Even though resulting Italian Carlo Bergamini class and French Aquitaine class ships look different, they use many common subsystems. The Carlo Bergamini class bears strong resemblance with the Horizon class, which was another joint Franco-Italian program.
FREMM Aquitaine Frigate: Details
These Italian Carlo Bergamini class warships are clearly destroyers, but being called frigates for political reasons. There are two variants of the Carlo Bergamini class. One of them are general purpose frigate, that are equally good at all aspects of naval warfare, while the other ships are optimized for anti-submarine warfare role. These have enhanced submarine hunting features, but at a cost of reduced land attack and anti-ship capabilities.
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 two helicopters on board. The vessels have a complement of about 200 people on board. Each vessel can accommodate one or two NH90 ASW helicopters or one NH90 and one EH101 helicopters. Moreover, each ship carries two RHIBs 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 door instead of VDS sonar in ASW variant.

These Italian warships have enhanced stealth features, including reduced radar cross section and noise levels. The “general purpose” version is operated by a crew of 199 men, while vessels optimized for anti-submarine operations have a crew of 201 men.
The primary radar is the Selex MFRA multi-functional active phased array radar. It can detect air targets at a range of more than 400 km. It also provides fire control for air defense missiles.
Selex MFRA multi-functional active phased array radar
The forward mast and the EMPAR MFRA radar on top – Image: navalanalyses.blogspot.com
At the top of the forward mast in a large round radome it is mounted the multi-function phased array radar, Selex EMPAR (European Multi-function Phased Array Radar) Multi-Function Radar Active (MFRA) / SPY-790 MFRA, which provides simultaneous surveillance, tracking and weapons control. The EMPAR MFRA is an active radar (Active Electronically Scanned Array – AESA) and not passive (Passive Electronically Scanned Array – PESA) as it is the EMPAR radar of the Orizzonte class destroyers. EMPAR is the primary sensor in the FSAF/SAAM-IT and PAAMS missile systems. It operates at C-band, performing concurrently 3D detection, multiple target tracking and missile guidance. Specifically, the multi-function capabilities include full volumetric search coverage, low altitude and surface search, multiple target tracking (up to 300 tracks) and up-link transmission when needed for missile guidance. It counters different threats such as high diving and sea skimming missiles, aircraft and helicopters and any kind of vessels. The system provides an almost continuous 360 degree view while the maximum range is about 120-150km for aircrafts and 25km for missiles. Source navalanalyses.blogspot.com
Status of the FREMM Programme
Planning assumptions for the Italian Navy are 10 FREMM-IT (4 ASW variants and 6 GP variants) at a cost of€5.8 billion.
FREMM-IT will replace the Maestrale and Lupo-class frigates in service with the Italian Navy.
As of 2014, the Italian government has approved funding for the first eight FREMM-IT to be delivered to the Italian Navy (4 ASW variants and 4 GP variants). In the 2013 Italian budget, the Italian government laid-out the necessary financing for two more GP variants (FREMM-IT 7 & 8) and the contract was awarded in September 2013. On 18 June 2014, the Defence Parliamentary Commission authorized units 9 and 10, that have to be funded by 16 April 2015.
FREMM-IT 9 & 10 will have AAW & ATBM capabilities and will have A70 VLS for cruise missiles. All Italian FREMM-ITs have extended AAW capabilities, with SAAM-ESD CMS and Aster 30 (& Aster 15) missiles for extended area defence. SAAM-ESD CMS use Selex ES MFRA, a 3D active radar (AESA), an evolved version of the Selex ES EMPAR PESA radar (previously embarked on Horizon-class destroyers and the aircraft carrier Cavour).
The Selex ES MFRA 4FF (EMPAR’s evolved version, destined for the 9th and 10th FREMM) will have four flat radar sensors, with three times the original range and full ATBM capabilities.
Since the 7th FREMM-IT, there will be updates to other systems, such as:
- the COC and bridge will be integrated
- the cruise speed will be enhanced to 19/20 knots (with more powerful diesel engines)
For years, Selex has become one of the leading manufacturers of technologies for defence systems, producing panoply of products developed to fulfil security needs of many armed forces. The stages of designing, developing as well as production of defence equipments were done with information superiority in mind. Two of Selex’s most successful surveillance radar systems are the RAN-30X/I along with the KRONOS 3D radar system.
Designed to compete in the “surveillance radar” category, the RAN-30X/I has climbed the vertical ladder to place itself among the most accomplished radar system available in the market. Selex has designed the radar with new a structural configuration, allowing for higher operational flexibility and adaptability to different platforms thus requiring minimal set-up time as well as operational cost.
The RAN-30X/I operates on four main roles. It was designed to perform multiple roles as a measure taken in fulfilling naval forces demand for multi-purpose radar. The roles are, Surface and Air Surveillance (mode 1) for small air and surface target detection, Anti-sea-skimmer detection (mode 2), Over the Horizon (OTH) detection (mode 3), and lastly the Helicopter control and navigation (mode 4).
Depending on the different operational mode, the radar, according to Selex has different instrumental range. In mode one at 15rpm, the radar has an efficiency range of 100km, followed by mode two at 30rpm with 40km efficient range. The third mode, with a gradual rotation of 3rpm, the radar scans for threats within a dazzling 200km range and lastly in mode 4, with 30rpm the radar has a range of 25km.
Currently operational onboard the Italian Navy’s “Cigala Fulgosi” OPV Class vessel, the radar is also currently operating on board Thailand’s Pattani class OPV which had successfully conducted an anti-piracy operation in the Gulf of Eden. This achievement, at one stage has marked the radar capability in supporting high-risk and high-stake high sea operations. Source asiapacificdefence.blogspot.com
Selex NA-25X fire control system
NA-25X which is a modern fire control system based on the ORION RTN-25X tracking naval radar, a J-band fully coherent equipment which is characterised by anti-nodding, extensive ECCM and anti-clutter features together with high tracking accuracy. A set of two EO sensors (TV camera, IR camera) can be mounted on the radar director, to enable firing assessment and to provide an alternative line-of-sight on the same target. A third sensor (Laser Range Finder) can be mounted to provide a complete EO tracker facility. NA-25X can be provided with a dedicated multifunctional console or controlled by any console of the Combat Management System (CMS). The FCS can be easily integrated in every CMS and completely remote accessible. A couple of Targets Designation Sight (TDS) enhance the FCS configuration. Through an internal additional function, NA-25X system can be integrated inside an Artillery System (including at least two FCSs), to optimize the use of all onboard guns against multiple concurrent targets (missiles, air and surface targets). The system perfomrs the following tasks: radar and optronic autonomous search with automatic/manual self-designation, surveillance and self designation on ship’s search radar video, automatic engagement of evaluated priority target up to firing action, automatic air/missile/shore and surface targets tracking, automatic detection of launched missile, control of up to three guns with different calibres in the anti-air/anti-surface warfare and CIWS roles, line-of-sight/line-of-fire stabilization and Track While Scan (TWS) on external naval data.

SLAT launchers with Canto-V anti-torpedo countermeasure system (ASW)
The CANTO-V is the next-generation anti-torpedo countermeasure system for existing and future surface ships developed by DCNS as part of the CONTRALTO-V product line. The CANTO-V countermeasure system consists of a pneumatic launcher and decoys designed to counter advanced torpedoes. CONTRALTO-V has been designed to operate with multiple launchers with the decoys being deployed following a ballistic trajectory. DCNS successfully conducted a series of test in May and June 2011. Source deagel.com
The ASW variant includes the DCNS CONTRALTO-V Torpedo Countermeasures system (or else known as SLAT system) for surface vessels. CONTRALTO®-V is composed of several subsystems for an optimized defense against torpedoes: the reaction system, which calculates and suggests optimized evasive manoeuvres and sets off the countermeasures, the deployment system (launcher) fitted to several types of launchers (mortar, pneumatic, rocket) and the CANTO®-V countermeasure. CANTO®-V is a broadband active acoustic countermeasure. It is designed to saturate the torpedo data processing system by emitting specific and smart acoustic signals covering the whole torpedo frequency band in both active and passive mode. Its mission consists in exhausting the threat by creating and constantly renewing hundreds of false targets on a 360-degree coverage area (5 sec deployment). This concept, called dilution/confusion, is the only one capable of defeating advanced torpedoes while consuming less munitions and it is efficient whatever the number of torpedoes or their types and doesn’t need to be deployed far from the threatened ship. The system offers a 95% escape probability against torpedoes detected at 3,000 meters. Watch the video to realize how the system works. Both ASW and GP variants are equipped with two OTO Melara/Selex SCLAR-H decoy launchers for 105mm or 118mm multipurpose rockets. Source navalanalyses.blogspot.com

Impiego: The SCLAR is a multiple rocket launcher system produced by Breda Meccanica Bresciana, typically used by ships for the launch of false targets such as flares and chaff. It has a caliber of 105 mm, lifting and swiveling, and can also fire rockets explosives in a radius of 10 km. The launcher is designed for accurate deployment of false targets thereby providing the passive defense against missiles for the ship radar and IR search; the typical mode of operation (at various intervals) include: Confusion (dilution); dissimulation; Distraction; dump;
Its main features are:
- possibility of loading simultaneously different types of rockets (Chaff, IR, flares);
- Automatic selection of the rockets to be launched;
- Possibility of repeated engagements, because of the availability of a large number of rockets, loaded into individual sealed containers;
- Automatic control by the ship’s electronic warfare suite;
- Full coordination with the active defense systems of the ship; – Ability to function in all weather conditions and in a position NBC (automatic)

Sonar CAPTAS 4
The Combined Active and Passive Towed Array Sonar (CAPTAS) is a family of long-range, Low Frequency Active Sonar (LFAS) systems developed by Thales Underwater Systems to support surface ship’s anti-submarine warfare (ASW) capability. The CAPTAS towed Variable Depth Sonar (VDS) is well suited for detection of modern diesel-powered submarines in the littoral, deep and shallow water environments. Its range of performance levels, defined by the power of acoustic transmission and the gain of the receiver subsystem, enables integration onto a wide range of surface ships such as corvettes, frigates and/or destroyers. CAPTAS family also features a faired tow cable for optimum Towed Body (TB) depth control, COTS processing architecture and port-starboard non ambiguous discrimination on receive array.

The CAPTAS 4 Compact is a smaller version of the CAPTAS 4 towed array sonar especially well suited to provide anti-submarine warfare (ASW) capabilities onboard medium-size frigates. The new sonar system is 20-percent lighter and 50-percent smaller than its parent system making possible to move the sensor package from ship to ship. Source deagel.com
The ships are equipped with a Thales UMS 4110 CL low frequency active and passive Bow Mounted Sonar. The hull mounted sonar covers a very large area providing ASW all-round surveillance as it can detect any kind of threat or object from a long range in any environmental condition. It has an excellent target positioning allowing to prosecute and engage distant submarines with organic weapons or airborne assets. Source navalanalyses.blogspot.com
Thales UMS 4110 CL hull sonar
The bow mounted UMS 4110 CL is a long-range sonar for offensive ASW (Anti-Submarine Warfare) and self-protection. It is designed for multi-mode operation and can simultaneously operate two active channels – ASW transmission modes – as well as passive channels for listening only or for the tracking of torpedoes. It also has the capability to carry out obstacle avoidance. A conventional cylindrical array lies at the heart of the UMS 4110 CL system, operating at about 5 kHz so as to exploit the range advantage of a rather low frequency.
In December 2001, Thales France and Alenia Marconi Systems were awarded a development contract for a new sonar system, known as 4110 CL, to be integrated into the four Horizon frigates. The 4110 CL is a hull-mounted medium frequencies sonar system featuring advanced signals processing. The development contract also included the procurement of four such sonar arrays to be mounted on two French and two Italian ships. The same sonar system was also selected for the FREMM multi-purpose frigates for the Navies of France and Italy. Source deagel.com

There is a 16-cell Vertical Launch System (VLS) for Aster-15 and Aster-30 surface-to-air missiles. The Aster-15 has a range of around 30 km, while the Aster-30 have a range of around 120 km. However this loadout of 16 missiles is comparatively small for such a large warship.
STRALES in front of VLS
Behind the front gun, it is installed a DCNS Sylver A50 VLS with 16 cells (two VLS modules) for MBDA Aster 15 anti-aircraft/missile 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. Source navalanalyses.blogspot.com
Aster air defence missile system
The ASTER modular family of vertically launched missiles have been designed to meet the high demanding requirements of the emerging air threats such as aircraft, UAVs, helicopters and specially missiles. The ASTER missiles can be installed on ground- and sea-based platforms. They feature hit-to-kill capability, a very valuable skill against ballistic missiles. The missile family entered service in 2002 with the French Armed Forces. The ASTER 15 and ASTER 30 are integrated on the SAAM (ASTER 15), PAAMS (ASTER 15 and ASTER 30) and SAMP/T (ASTER 30) air defense systems. These systems will be employed by the armed forces of France, Italy and the United Kingdom.
ASTER 15 and ASTER 30
ASTER 15/30 – Image: mbda-systems.com
The two-stage ASTER missiles are provided with two different solid propellant boosters resulting in the ASTER 15 and the ASTER 30 models. The ‘Pif-Paf’ control system enables the ASTER missile to counter high maneuverable missiles achieving a direct impact (hit-to-kill). The ‘Pif-Paf’ propulsion combines conventional aerodynamic control with control by gas jets acting through the centre of gravity of the missile. Until mid-course the guidance of an ASTER missile is based on the Inertial Navigation System (INS) updated through an uplink, in the terminal phase the guidance is provided by an active Radiofrequency seeker. The final stage of the ASTER missile is a ‘dart’ equipped with the seeker, a sustainer motor, a proximity fuze and a blast fragmentation warhead.

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. Source navalanalyses.blogspot.com

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. Source navalanalyses.blogspot.com
4 x OTOMAT anti-ship missiles (GP)
The Otomat Mk2 Block IV is an all-weather, subsonic, long range, sea-skimming anti-ship missile with extended capabilities for littoral warfare and coastal attack missions. The Otomat Block IV missiles can be retargeted and carry out coordinated attacks. It can be installed on different fighting ships from small fast patrol boats to large destroyers and cruisers.
The Otomat missiles can be launch irrespective of ship’s bearing, the target data is provided by the sensors of the ship. Once launched, the missile is guided through he INS supported by the GPS and a radar altimeter. Target information can be updated from ship’s sensors or another platform via a protected built-in radio-link. The terminal phase of the attack is performed through the active radar seeker.
The Otomat Block IV missile can perform maneuvers, simultaneous arrival at the target area and different attack directions in order to escape ship’s defenses and increase the kill probability. The Otomat is also well protected against the effects of countermeasures. It is provided with an impressive 210 kg semi-piercing warhead detonated by proximity, contact and grazing.

The ASW variant of the Bergamini class is also armed with four MILAS anti-submarine missile system. MILAS is the European counterpart to the ASROC. Derived from the OTOMAT MK2 missile system, MILAS is an all weather, anti-submarine warfare weapon system designed to operate in conjunction with modern detection systems such as very low frequency active and passive sonar which provide long range detection combined with very high precision. MILAS is designed to carry and release an MU-90, or similar lightweight torpedo, close to the designated submarine position, as indicated by the ship sonar or by a co-operating ASW helicopter or MPA.

MILAS is capable of ranges from 5 to in excess of 35 km in all directions. The firing system is highly automated and requires only a single operator. Once the ship’s sonar has detected an enemy submarine, the sonar contact is analysed and classified before a target designation is sent to a dedicated MILAS console. The system effectiveness relies on the capability to update the trajectory and the torpedo release point continuously during the missile flight, with the added advantage of modifying the torpedo settings in respect of target manoeuvres.

The MILAS missile, featuring 360° gyro-deviation and in-flight re-vectoring to counter any avoidance measures carried out by the target, then delivers the torpedo in the immediate vicinity of the enemy submarine. On entering the water, the torpedo activates its own sonar detection and propulsion systems. Then, after a rapid searching phase, it proceeds to attack and destroy the target. With its fast reaction time, operational range and availability, the system provides the launching ship and the escorted naval formation permanent and effective defence against the submarine, be it conventional or nuclear. MILAS missiles can also be used together with OTOMAT MK 2 missiles in a common system/ launcher for combined ASW and ASuW. It is bigger than Otomat, 6m long and 800 kg. Developed in co-operation by France and Italy, MILAS is in operational service only with the Italian Navy until today. Source navalanalyses.blogspot.com

These Italian warships have a double hangar for helicopters and can accommodate either two NH90, or one NH90 and one AW101. These are used for search and rescue, utility operations, long-range anti-submarine and anti-ship warfare.
NH90 multi-role helicopter: Details
The AugustaWestland AW101 is a modern naval utility helicopter. Originally this chopper was known as Eurocopter Industries EH101. It was jointly developed and produced by Augusta of Italy and Westland Helicopters from United Kingdom.
The EH 101 had its roots in a UK project to replace the Sea King. The design was later revised to meet Italian navy as well as Royal Navy requirements. Westland and Agusta established European Helicopter Industries Ltd, which received formal go-ahead in 1984 for nine prototypes and subsequent development of what became the EH 101. The first prototype made its maiden flight in 1987.
In 2000 Augusta and Westland Helicopters merged and formed AugustaWestland. Since 2007 this helicopter is marketed as AugustaWestland AW101. There are utility and anti-submarine warfare versions of this helicopter.
The EH101/AW101 is in service with Italy and United Kingdom. It has been exported to Algeria, Canada (CH-149 Cormorant), Denmark, Nigeria, Portugal, Saudi Arabia, and Turkmenistan. It is license-produced in Japan (Kawasaki MCH-101) and the United States. It is worth noting that Britain, Denmark and Portugal use the name Merlin for this helicopter.

Indal Twin Claw (TC-ASIST)
An intelligent claw capture system for non-probe installed aircraft
While Indal ASIST (Aircraft Ship Integrated Secure and Traverse) is a popular system for those navies that have probe-equipped helicopters, for some navies the option to install a telescoping probe on their existing helicopters is difficult. In order to support non-probe installed aircraft, Curtiss-Wright has developed the Indal Twin Claw (TC-ASIST) system, a derivative of its already proven and successful ASIST system.
The TC-ASIST system provides full security after landing and through all on-deck operations, up to and including Sea State 6 conditions. The pilot, assisted by visual cues, flies the aircraft to a position over the designated landing area on the flight deck. The Indal Rapid Securing Device (RSD), fitted with a pair of claw arms designed to capture and secure the wheel spurs of the aircraft, tracks the helicopter position with the capture arms at a ready position at either end of the RSD. The claw arms are spring loaded and held in the down position until tire sensors contact each tire as the arms are brought in. Upon contact, spring force rotates the claw arm upwards until it contacts the wheel spur. Each claw arm acts independently, but they are mechanically interlocked to ensure simultaneous operation.
Once the aircraft is secured, it is ready to be aligned/straightened for traversing from the designated landing area to the hangar or any intermediate location. All deck handling operations can be accomplished without the need for personnel on the flight deck.
|General||Provides positive, uninterrupted securing provided at all times|
|Recovery Assist||Optional ASIST style helicopter tracking system available to supplement standard deck cues and line up lines
100% free-deck landing
|Capture Area||3~4 m2 [typical]
Compatible with harpoon deck-lock grid
|Maneuvering and Traversing||Achieved through single operator controlled movement of Rapid Securing Device along deck track
Constant helicopter lateral positioning maintained during traversing

The Carlo Bergamini class have an advanced Combined Diesel-Electric and Gas (CODLAG) propulsion system. For normal operation the ships use a single General Electric LM2500+G4 gas turbine, developing 42 900 shp. For slow-speed and quiet anti-submarine operations the ships use hybrid electric propulsion with two 2.5 MW electric motors which are connected to the propeller shafts. These are powered by 4 diesel generators. Maximum speed is 29 knots (55 km/h). Maximum range is 6 700 nautical miles (12 300 km) at 15 knots (28 km/h). So Italian vessels are slightly faster and have longer range than their French counterparts.
1 x General Electric LM2500
The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine.
The LM2500 is available in 3 different versions:
- The LM2500 delivers 33,600 shaft horsepower (shp) (25,060 kW) with a thermal efficiency of 37 percent at ISO conditions. When coupled with an electric generator, it delivers 24 MW of electricity at 60 Hz with a thermal efficiency of 36 percent at ISO conditions.
- The improved, 3rd generation, LM2500+ version of the turbine delivers 40,500 shp (30,200 kW) with a thermal efficiency of 39 percent at ISO conditions. When coupled with an electric generator, it delivers 29 MW of electricity at 60 Hz with a thermal efficiency of 38 percent at ISO conditions.
- The latest, 4th generation, LM2500+G4 version was introduced in November 2005 and delivers 47,370 shp (35,320 kW) with a thermal efficiency of 39.3 percent at ISO conditions.
LM2500 installations place the engine inside a metal container for sound and heat isolation from the rest of the machinery spaces. This container is very near the size of a standard 40-foot (12 m) intermodal shipping container – but not the same, the engine size very slightly exceeds those dimensions. The air intake ducting may be designed and shaped appropriately for easy removal of the LM2500 from their ships. Source wikiwand.com
