The Hellenic Navy is expanding its fleet with the addition of a fourth FDI frigate after Greece signed a fresh contract with Naval Group. The newly approved deal covers not only the construction of the additional vessel but also the maintenance of the FDI fleet and further capability enhancements. The fourth ship, priced at 982 million euros ($1.1 billion), follows formal negotiations between Greece and France’s defense procurement authorities.
A notable aspect of the agreement is the inclusion of Greek industry: around 25 percent of the shipbuilding work and specialized components will be supplied by domestic companies. Greece launched the FDI program in 2022 with an order for three frigates, while reserving the option for a fourth. Naval Group has continued to advance the program, with all three initial vessels already under construction. The first frigate is expected to be delivered before the end of the year.
FDI frigates are high-tech combat ships designed for multi-domain naval warfare, including air defense, anti-submarine operations, surface strike missions, and protection against unconventional threats. With a scalable architecture and advanced digital backbone, the vessels are equipped to counter modern challenges such as cyberattacks and next-generation missile threats. Their compact design and hydrodynamic hull ensure effective operation in diverse maritime environments, from rough oceans to archipelagic waters.
The ships incorporate extensive automation, enabling reduced crew requirements and streamlined maintenance—key advantages in sustaining long-term naval readiness. Built in accordance with NATO standards, the FDIs offer seamless interoperability with allied fleets. Sea trials conducted in the Atlantic under high-sea and strong-wave conditions have validated the frigates’ resilience, maneuverability, and combat readiness, according to Naval Group.
