The FREMM (“European multi-purpose frigate”; French: Frégate européenne multi-mission; Italian: Fregata europea multi-missione) is a class of multi-purpose frigates designed by DCNS/Armaris and Fincantieri for the navies of France and Italy. The lead ship of the class, Aquitaine, was commissioned in November 2012 by the French Navy. In France the class is known as the Aquitaine class, while in Italy they are known as the Bergamini class. Italy has ordered six general purpose variants and four anti-submarine variants; the last two Italian general purpose FREMMs will have anti-aircraft warfare, anti-ballistic missile and surface attack capabilities. France has ordered six anti-submarine variants, and two air-defence variants.
Three original variants of the FREMM were proposed; an anti-submarine variant (ASW) and a general-purpose variant (GP) and a land-attack variant (AVT) to replace the existing classes of frigates within the French and Italian navies. A total of 27 FREMM were to be constructed – 17 for France and 10 for Italy – with additional aims to seek exports, however budget cuts and changing requirements has seen this number drop significantly (for France). The land-attack variant (AVT) was subsequently cancelled.
Anti-air warfare variant of FREMM
A third anti-air warfare variant of FREMM was proposed by DCNS in repose to French requirements for a new air-defence frigate, the new variant became known as FREDA (“FREgates de Défense Aériennes“, “Air defence frigate”). This new French requirement was due to the third and fourth Horizon-class frigates being cancelled after the first two cost €1,350m each, but this decision left French Navy still in-need of replacements for its ageing Cassard-class air-defence frigates.
As of 2009, the FREDA design features a more powerful version of the Thales Herakles passive electronically scanned array radar and 32 cells of SYLVER A50 in place of the 16 cells of A43 and 16 cells of A70. The SYLVER A50 would allow it to fire the 120 kilometres (75 mi)-range Aster 30 missile; the towed array sonar would not be fitted.

Original plans were for 17 FREMM to replace the nine D’Estienne d’Orves-class avisos and nine anti-submarine frigates of the Tourville and Georges Leygues classes. In November 2005 France announced a contract of €3.5bn for development and the first eight hulls, with options for nine more costing €2.95bn split over two tranches (totaling 17).
Following the cancellation of the 3rd and 4th of the Horizon-class frigates in 2005 on budget grounds, requirements for an air-defence derivative of the FREMM called FREDA were placed – with DCNS coming up with several proposals. Expectations were that the last 2 ships of the 17 FREMM planned would built to FREDA specifications, however by 2008 the plan was revised down to just 11 FREMM (9 ASW variants and 2 FREDA variants) at a cost of €8.75bn (FY13, ~US$12bn). The 11 ships would cost €670m (~US$760m) each in FY2014, or €860m (~US$980m) including development costs.
The 2013 White Paper on Defence and National Security committed France to 15 front-line frigates, which was initially wrongly interpreted as 2 Horizons, 5 La Fayettes and a reduction in the FREMM fleet down to 8 ships. The 2014/2019 defence plan restated a target of 11 FREMMs; the current plan is to deliver 6 ASW variants to replace the Georges Leygues-class frigates by 2019, followed by two anti-air variants to replace the ageing Cassard-class frigates and a decision will be taken in 2016 on what version the remaining three will be. In 2014, the French Navy’s Chief of Staff, Adm. Bernard Rogel, confirmed that 11 FREMM frigates had been ordered but in 2015 the order was cut to 8 in order to allow the purchase of five FTI Mid-Size Frigates from 2023. The FTI will replace the La Fayette-class class, which will be fitted with a sonar as an interim measure

The DART projectile is made of two parts: the forward is free to rotate and has two small canard wings for flight control. The aft part has the 2.5 kg warhead (with tungsten cubes and the 3A millimetric wave new fuse), six fixed wings and the radio receivers.MU 90 torpedoes with Calzoni AHS (Automatic Handling System)C310 is an anti-torpedo countermeasure system for surface shipsC310 @finmeccanica.com
The C310 represent WASS’ high-performance anti-torpedo countermeasure system. It’s designed to resist the attacks of the most technologically advanced torpedoes, wire-guided or not (launch-and-forget)
They are realized with electronic items that generate disturbance noise for the acoustic head of the enemy torpedo.
This kind of countermeasure can both represent dummy mobile targets (MTE) and generate disturbance noise for the acoustic head of the enemy torpedo (Jammers). The combination of mobile Decoys and Jammers has the purpose of cheating the torpedo, which directs its attacks towards the dummy targets, thus allowing the ship to perform an evasive countermeasure.
The definition of optimal reaction results using a elaboration software (ORACOM) that, based on multiple parameters, elaborates the more suitable operation to maximize surviving probabilities, even against last generation torpedoes with high potentials against contermeasures. @finmeccanica.com

HERAKLES is Thales’ latest radar designed to be the sole radar on board high-value vessels. Operating in S band and optimized for littoral operations, it provides an effective naval air defence and land operations support capability with optimum acquisition and life cycle costs. The radar simultaneously performs all the functions involved in the establishment of a 3D air and surface picture, missile detection, and in weapon deployment, can be associated with all types of active or semi-active surface-to-air missiles, features exceptional reliability and extremely high operational availability, key to its role as sole radar.Terma Scanter 2001 radar – As the density of traffic in the ports, waterways and airports grows, markets increasingly demand high performance radars in order to maintain security.
