PARIS -- On March 31, the French Defense Procurement Agency (DGA) placed an order with Naval Group for a fifth Defence and Intervention Frigate (FDI) for the French Navy, expanding a program launched in 2017 to modernize the country’s surface combatant fleet. The lead ship, Amiral Ronarc’h, was delivered in October 2025 and is currently undergoing initial operational deployment, with the remaining vessels scheduled for delivery between 2027 and 2032.
Naval Group's FDI frigate design is currently planned for service with both the French and Greek navies.
The FDI is equipped with Exocet MM40 Block 3C anti-ship missiles, Aster 15 and 30 surface-to-air missiles, MU-90 Impact torpedoes, and 76mm and 20mm naval guns. Aviation facilities support simultaneous operation of a helicopter and an unmanned system, while onboard capacity allows for deployment of special forces and commando boats.
The class incorporates a fully digital architecture, centered on a cyber-secure and redundant onboard data infrastructure supporting combat system functions and sensor integration. Operationally, the design includes a dedicated station for countering asymmetric threats such as UAVs and small surface attackers, separate from the primary operations center. The FDI also features an integrated mast housing sensor system, including the Thales Sea Fire fixed-panel radar, enabling continuous 360-degree surveillance and enhanced situational awareness.
