Greece has signed a new contract with France’s Naval Group to build an additional Defense and Intervention Frigate (FDI) for the Hellenic Navy. The agreement includes the fourth vessel’s acquisition, maintenance, and upgrades for the existing FDI fleet, with roughly 25% of work sourced from Greek industry.
Athens negotiated the 982-million-euro ($1.1-billion) deal with France’s defense procurement agency, expanding the FDI HN program launched in 2022. The first three ships—part of the original contract—are already under construction, with the lead frigate expected by year’s end.
FDI frigates are multi-mission warships designed for anti-air, anti-submarine, anti-surface, and asymmetric operations. Their scalable architecture, advanced digital systems, and cybersecurity features allow them to counter threats including supersonic missiles and cyberattacks. Optimized for harsh or diverse maritime environments, they use automated systems that reduce crew requirements and enhance availability. Built to NATO standards, the ships have proven stability and performance during Atlantic sea trials.
