France Orders Two FDI Frigates

March 29, 2021 (Google Translation) – The Directorate General of Armaments (DGA) notified Naval Group and Thales of the order for two defense and intervention frigates (FDI), Admiral Louzeau and Admiral Castex , which will be delivered in 2025.

Complementing the FREMMs, the FDI are able to intervene in all areas of wrestling on the high seas. They incorporate many innovations, including the world’s first fully digital fixed panel radar.

These two new frigates are added to Admiral Ronarc’h , the first FDI ordered in April 2017 by the DGA from Naval Group and Thales, the first sheet of which was cut in October 2019, and which will be delivered to the French Navy in 2024.

MBDA, in charge of the on-board missile firing facilities, is associated with these orders.

The one-year advancement of Admiral Castex’s order makes it possible to respond more quickly to the Navy’s operational need for modern, first-rate frigates. This order also contributes to supporting the know-how and skills of the Lorient shipyard at the highest level of technicality, qualities which today enable it to produce buildings at the best world level for the French Navy as well as for its export customers.

Five IDFs will be in service by 2030, allowing the French Navy to achieve the format of fifteen first-rank frigates, in line with the objective of the 2019-2025 military programming law.

The FDI program participates in the renewal and strengthening of the surface fleet of the French Navy, which will thus have fifteen first-rate frigates in 2030: 8 multi-mission frigates (FREMM), 2 air defense frigates (FDA Horizon) and 5 defense and intervention frigates (FDI).

With a crew of 125 sailors, the IDF are 4,500-ton class ships, versatile and enduring. Able to last on the high seas and to use a combat helicopter, they are designed to operate in an environment contested by the adversary, in all areas of combat and in the face of high-level threats. Finally, they benefit from the ability to overcome combat damage and from the interoperability required by combat vessels.

From their conception, the FDI integrate a concentrate of innovations :

  • They can intervene in all areas of warfare on the high seas: anti-ship, anti-aircraft, anti-submarine.
  • Able to control vast air and sea spaces, they are also capable of defending themselves against asymmetric threats and of projecting a detachment of special forces.
  • To evolve in an increasingly digital world, the IDF have the capacity to fight against the cyber threat and two digital data centers which combine the computing capacities of all the sensors and weapons on board.
  • Among the new generation equipment installed on board is a radar with four fixed panels integrated on a single mast allowing permanent 360-degree watch, and launchers capable of firing several types of anti-aircraft missiles depending on the threat to be treated. They are also the first frigates to have sufficient space to be able to simultaneously embark a helicopter and a drone of the 700 kg class.
  • Innovative frigates, the IDF are equipped with systems integrating cutting-edge technologies and are designed according to an incremental development logic, with successive standards making it possible to incorporate any new capacity needs or technological developments during their period of operational service.
