First FDI Frigate Undergoing Sea Trials

The Amiral Ronarc'h — the lead ship of the French Navy's FDI (defence and intervention frigates) programme — is currently undergoing sea trials ahead of its permanent deployment.

The 122-metre Frégate de défense et d'intervention was launched at the end of 2022; more recently construction of its sister vessels HS Kimon and HS Nearchos, destined for the Greek Navy, were also completed.

As per a recent Naval Group press statement, FDI Amiral Ronarc'h sailed from Lorient, Brittany, to begin her sea trials. These tests go beyond former completed checks on propulsion and navigation systems and are designed to check combat systems in realistic maritime conditions.

The Naval Group statement noted: "The feedback from her trials will benefit the other units ordered by the French Navy and the Hellenic Navy."

The FDI frigate has been designed to operate as a multipurpose vessel capable of all types of combat: anti-ship, anti-air, anti-submarine, asymmetric threats and special forces projection.

With a crew of 125, she has a 4,500 tonne displacement and is capable of travelling at 27 knots. She is armed with Exocet MM40 anti-ship missiles, ASTER anti-aircraft missiles, and MU90 antisubmarine torpedoes.

The FDIs intended for the French Navy can carry an NH90 heavy helicopter or the future H160M plus an aerial drone, as well as commando boats for special forces. They are also equipped with the new-generation Sea Fire radar developed by Thales.

The Amiral Ronarc'h is expected to enter full service some time in 2025; she will be the first of an eventual five planned FDI frigates for the French Navy in a €2.1 billion deal with Naval Group and subcontractors.
