This contract extends the ongoing partnership between Exail and Naval Group, following the successful implementation of Exail’s navigation systems on the French Navy’s FDI frigates.
The Hellenic Navy’s FDI frigates are designed as multi-role vessels capable of conducting various missions, including anti-air, anti-surface, and anti-submarine warfare, as well as supporting special operations.
They are equipped with advanced combat systems and a cyber-resilient digital infrastructure to operate effectively in challenging environments.
In May 2025, Naval Group began sea trials for HS Kimon, the first FDI frigate for the Hellenic Navy, at its Lorient shipyard.
The initial phase of the trials focuses on evaluating platform systems, including propulsion and navigation. A second phase will assess the vessel’s combat systems and endurance at sea.
