The Amiral Ronarc'h-class frigate is Naval Group's FDI family, a compact French multi-role combat ship with digital and cyber-secure architecture. The lead ship began sea trials in 2024, was delivered to the French Navy in October 2025, and later started a long-duration deployment before expected active service in 2026.
No publicly documented use in a named armed conflict found in the sources reviewed. Public sources describe the first FDI frigate's delivery, sea trials, and long-duration deployment for capability validation before full operational service.
