FTI Medium-Size Frigates, France


FTI medium-size frigates

A prototype of the export variant (designated BELH@RRA) of the French Navy's future FTI (Frégate de Taille Intermédiaire) medium-size frigates was unveiled during the Euronaval trade show held in Paris in October.

The French Navy version is being developed by naval shipbuilding company DCNS in collaboration with the French Defence Procurement Agency (DGA), under the FTI medium-size frigate programme.

Thales has been contracted to supply latest-generation navigation and communications equipment for the frigates.

The heavily armed frigates can be deployed in a wide range of missions such as anti-surface warfare, anti-submarine warfare, anti-aircraft warfare, patrol, maritime security, control of exclusive economic zone (EEZ), asymmetric warfare, and special forces activities.

The French Navy plans to order up to five units with deliveries, beginning 2023.

French Navy's FTI frigate design and features

The FTI medium-size frigate will feature modular design with increased self-defence and long-range capabilities.

Overall length and midship beams of the ship are 122m and 17.7m respectively. With a displacement of approximately 4,200t, the frigate will carry up to 150 personnel, including 110 crew and 15 for helicopter detachment.

The ship will incorporate digital technologies for data processing and detection of evolving threats. Its wheelhouse will be positioned in the middle section.

A hangar and flight deck located at the stern will of the frigate will allow for the operation of a single unmanned rotorcraft system and / or NH-90 medium class military helicopter equipped with FLASH-based dipping sonar and MU90 lightweight anti-submarine torpedoes.

The medium-size frigate will additionally carry rigid hulled inflatable boats for patrolling and transportation.

Anti-aircraft and anti-submarine armament

The FTI will be armed with a variety of anti-aircraft and anti-submarine armament to attack aircraft and submarines and their crew.

An Oto Melara 76mm or 127mm naval gun will be mounted in a gun turret located in the bow deck to fight against enemy aircraft, submarines, missiles and ground-based threats.

Defence against littoral and coastal land threats will be provided by eight Exocet MM40 Block 3 all-weather weapon systems, installed amidships.

The frigate will also be fitted with two eight-cell A-50 type Sylver vertical launch systems for Aster 15 surface-to-air missiles in the bow, two 20mm remotely-operated weapons at the rear, 2x2 deck-mounted torpedo tubes for MU90, and an anti-ship missile decoy launching system.

Navigation and communication systems aboard FTI

The frigate will be equipped with efficient countermeasures, navigation and communications equipment manufactured by Thales.

"The heavily armed frigates can be deployed in a wide range of missions such as anti-surface warfare, anti-submarine warfare, anti-aircraft warfare, patrol, maritime security, control of exclusive economic zone (EEZ), asymmetric warfare, and special forces activities."

They include Sea Fire 500 multi-function active fixed-array antenna radar, Kingklip Mark II hull-mounted sonar, Aquilon integrated naval communication system, radar and communications electronic support measures for electronic warfare, jammers, and a compact version of the combined active passive towed array sonar (CAPTAS-4).

A non-rotating IFF (identification friend or foe) antenna system will equip the frigate to provide surveillance and monitoring at sea.

Combat management system

The FTI frigate will be equipped with DCNS' ship enhanced tactical information system (SETIS) combat management system, which provides the operator with improved decision-making and battle management capabilities.

Featuring man-machine interface, the SETIS system integrates onboard combat systems, command support modules and planning tools.

Propulsion and performance of French medium-size frigates

Propulsion for the multi-mission frigate will be provided by a 32MW combined diesel and diesel (CODAD) propulsion system.

The mid-size frigate will have a maximum speed of 27kts and a range of 5,000nm at a speed of 15kt.
