- The delivery of Amiral Ronarc’h, the first ship in the FDI series, is a major milestone for Naval Group. This new generation of high-end, multi-mission frigates will soon enter operational service and significantly enhance the capabilities of our French Navy thanks to its outstanding performance, already proven during sea trials. We are fully committed to this strategic programme and proud to deliver it for the French fleet, said Pierre Éric Pommellet, Chairman and CEO of Naval Group.

FDI – a new-generation frigate ready for high-intensity naval operations

The FDI (Frégate de Défense et d’Intervention) represents the next generation of first-rank, multi-role combat ships, succeeding the FREMM-class. Designed to counter all modern threats — from air, surface and subsurface targets to asymmetric and cyber threats — it combines state-of-the-art digital, sensor and data-processing technologies.

This highly versatile vessel can operate autonomously or within a task force, offering adaptability to a wide range of maritime environments, including open oceans and complex archipelagic zones. During her 14 weeks of sea trials in the Atlantic, Amiral Ronarc’h demonstrated excellent seaworthiness, maintaining performance in sea state 6 conditions.

The ship’s advanced automation systems enable operation with a reduced crew while ensuring high availability and maintainability. The FDI’s operational capabilities are comparable to the French Navy’s FREMM frigates, which have achieved an 80% availability rate over the past decade. Built to NATO standards, the vessel ensures full interoperability with allied navies.

A modern industrial process – up to two frigates per year

Naval Group’s Lorient shipyard has implemented a modern and efficient production process, allowing for the construction of up to two FDI frigates annually.

Five frigates are currently under construction for both the French Navy and the Hellenic Navy, at various stages of completion. The second FDI, HS Kimon, built for Greece, is now undergoing sea trials and is scheduled for delivery at the end of 2025, followed by two additional Greek units in 2026. The next frigate for the French Navy will be delivered in 2027.

Each FDI represents approximately one million hours of production and one million hours of design and development, engaging around 1,200 Naval Group employees and 400 subcontractors.

FDI main specifications

• Displacement: 4,500 tonnes
• Length: 122 m
• Beam: 18 m
• Speed: 27 knots
• Endurance: 45 days
• Complement: 125 crew + 28 passengers
