Forbin’s main mission is air defense. This mission brings together two very distinct tasks:
- Ensure the protection of a force (naval, amphibious and even civilian) against the air threats posed by aircraft and their weapon systems, including supersonic anti-ship missiles.
- Provide command and coordination of air operations from the sea, including those involving foreign or Air Force aircraft.
The frigate’s capabilities in other areas of struggle also guarantee his ability to fulfill missions of a very diverse nature: (securing a maritime zone, controlling commercial traffic, evacuating nationals.

As an integral part of air defense, electronic warfare systems aim to quickly identify the threat and implement decoy and jamming capabilities to neutralize enemy weapons. They have enhanced capabilities to respond to hostile electromagnetic emissions:
- Interception, direction finding and fine analysis of radar emissions
- Interception and fine analysis of radio broadcasts
- Implementation of countermeasures (jammers and new generation SAGAIE lures) effective against radar or homing missiles of enemy missiles.
Information and Communication System
Capable of integrating into a joint and combined environment and ensuring the support of an embarked staff, the air defense frigates have modern information and communication systems.
- The integrated telecommunications system (FICS) provides the interfacing:
- Information Systems and Command Support Systems (SIC 21)
- tactical data link systems (L11, L16)
- satellite and radio communication systems (ARISTOTE, SYRACUSE)
Wrestling and self-defense
Designed primarily for the air defense of a carrier group, frigates of this type are also able to escort and protect poorly-armed ships.
They have the following means:
- 8 missiles MM 40 EXOCET (IV x 2)
- 2 turrets armed with a 76 mm AA OTO-Melara compact SR (Ix2) gun that can be used at close range against an enemy ship or aircraft.
- 2 x 20mm AA F2 guns dedicated to protecting the frigate against hostile light craft.
In their chosen field, these frigates are distinguished by airspace control capabilities and particularly powerful means of action characterized by the PAAMS weapon system. The aim of this system is to provide this type of frigate with a system capable of protecting a maritime force from an air threat including maneuvering supersonic missiles. In addition to this, the frigates have the ability to guide friendly fighter planes to intercept any aircraft.
The PAAMS weapon system (Principal AntiAir Missile System) includes a fire control system consisting of:
- EMPAR multifunction radar (MFR);
- S1850M long-range surveillance radar (LRR) – three-dimensional detection capability greater than 200 km;
- 6 vertical SYLVER launchers (A50);
- 48 Aster missiles (32 Aster 30 and 16 Aster 15 missiles) – ability to destroy an air target up to 100 km;
- and control and control means (C2) for managing and coordinating the system, and for interfacing with the system
The struggle under the sea
Air Defense frigates are characterized by their versatility and ability to deal with any kind of threat.
Against enemy submarines and their torpedoes, they can implement a set of means, associated within the antitank system (SLAT) and including:
- detection capabilities, consisting of an active hull sonar and a towed linear antenna;
- combat capabilities, consisting of decoy launchers and MU 90 torpedoes
The Air Defense frigates can accommodate a heavy Cayman Marine (11 tons) helicopter .
A full-fledged weapon system, Caiman Marine ‘s mission is to:
- Contribute to the protection of the frigate and escorted ships by increasing the range of detection on the front.
- Neutralize enemy submarines and torpedoes with the MU 90 torpedo .
- 27 officers
- 120 petty officers
- 46 quartermasters and sailors
