Greece has ordered a fourth Defence and Intervention Frigate (FDI) from France’s Naval Group, expanding the Hellenic Navy’s surface fleet under its broader modernization programme. The agreement was signed on 14 November 2025 by Major General Ioannis Bouras, Director General of the Hellenic General Directorate of Defense Investments and Armaments (GDDIA), and Naval Group CEO Pierre Éric Pommellet.
This order follows the initial FDI programme launched in 2022, which included three frigates with an option for a fourth. All three earlier vessels are currently under construction, with the first expected to be delivered by the end of 2025. The latest contract also includes an expanded industrial cooperation component, with Greek defence companies contributing to the construction and integration work.
Key Features of the FDI Frigate
The FDI-class frigate is designed as a multi-mission combat vessel capable of operating across a range of naval environments. Its main characteristics include:
-
Multi-domain capability for anti-air, anti-surface, anti-submarine, and asymmetric operations
-
A modern digital combat system with advanced sensors and cyber-resilience features
-
Flexibility for both independent missions and fleet-level operations
-
High-performance sea-keeping, demonstrated during trials in rough Atlantic conditions
-
Automated systems allowing operation with a reduced crew and improved maintainability
-
Compliance with NATO interoperability standards
Part of Greece’s Wider Modernization Effort
The acquisition of a fourth FDI frigate aligns with Greece’s broader strategy to modernize its armed forces, upgrade maritime surveillance and deterrence in the Eastern Mediterranean, and replace aging naval platforms with more capable assets. The programme also strengthens defence-industrial cooperation with European partners and enhances the Hellenic Navy’s long-term operational readiness.
Naval Group noted that the progress on the first three ships is on schedule and described the latest order as a continuation of the Hellenic Navy’s fleet renewal plan.
