Advancements in Naval Defense: Greece Acquires Fourth FDI Frigate

Overview of the FDI Frigate Program

On November 17, 2025, an important milestone was reached in naval defense cooperation between Greece and Naval Group with the acquisition of a fourth FDI (Frégate de Defense et d’Intervention) frigate. This addition not only enhances the capabilities of the Hellenic Navy (HN) but also signifies a deepening industrial partnership that began with the FDI HN program launched in 2022.

The program initially comprised the procurement of three frigates, with the option for a fourth. Currently, the first three vessels are under construction, with the inaugural frigate expected to be delivered by the end of 2025.

Strategic Importance of the Fourth Frigate

Pierre Eric Pommellet, Chairman and CEO of Naval Group, expressed gratitude towards Greece for their continued investment, noting that this order reflects a strong endorsement of the FDI’s design and capabilities. The frigates are crafted to bolster the Hellenic Navy’s operational competence and maritime dominance, asserting Greece’s naval sovereignty in increasingly complex global waters.

Key aspects of this acquisition include:

• Increased Local Involvement: Naval Group has committed to enhancing the integration of Greek enterprises into its international supply chain, aiming for 25% local content in the new frigate.
• Enhanced Capabilities: The FDI program enables Greece to address contemporary and prospective maritime threats effectively.

Technical Specifications of the FDI Frigate

The FDI frigate exemplifies state-of-the-art naval technology with the following attributes:

• Combat Versatility: This vessel is designed for multi-domain operations, capable of anti-air, anti-surface, and anti-submarine warfare, while also effectively countering asymmetric threats.
• Operational Flexibility: With advanced digital and data processing systems, the frigate can deploy both independently and as part of a coordinated fleet to address various threats, including advanced submarines and cyber warfare.

Adaptability and Sea Worthiness

The compact and innovative design of the FDI enables it to operate optimally in diverse maritime environments, from turbulent seas to archipelagos. It has demonstrated its sea-keeping capabilities under challenging conditions, notably during sea trials where it handled waves of up to Sea State 7.

High Maintainability and Operational Readiness

One of the standout features of the FDI frigate is its high degree of maintainability. The ship’s automated systems allow for efficient operation with a reduced crew size, thereby optimizing operational uptime and reducing maintenance durations. This is crucial for enhancing naval readiness in a dynamic and often unpredictable maritime landscape.

• Interoperability with NATO Forces: In alignment with NATO guidelines, the FDI is engineered for seamless cooperation with allied navies, ensuring effective collaboration during joint operations.

Conclusion

The addition of the fourth FDI frigate marks an exciting chapter in Greece’s naval modernization efforts and demonstrates a comprehensive approach to enhancing maritime security. With increasing complexities in global maritime operations, the FDI stands out as a formidable asset, reinforcing the Hellenic Navy’s pivotal role in regional stability and defense initiatives. Through strategic partnerships and investments in advanced naval capabilities, Greece is poised to maintain a competitive edge in its maritime endeavors.
