Hellenic Navy Receives Its Second FDI Frigate Built by Naval Group

Naval Group delivered HS Nearchos, designated F602, to the Hellenic Navy on October 30 in Lorient, France. The ceremony included Nikos Dendias, Greece’s Minister of National Defense, and Catherine Vautrin, Minister of the Armed Forces. Nearchos is the second of four Greek FDI frigates.

The ship differs from lead vessel HS Kimon through its Standard 2 combat configuration. That configuration adds two A50 SYLVER vertical-launch modules, four SYLENA Mk1 launchers for air defense, and a 21-cell RAM close-in weapon system. Athanasios Martinos is the ship’s sponsor, and Commander Vasileios Karagiannakis commands it.

Kimon was delivered in December 2025, while Nearchos arrived ten months later. HS Formion is planned for delivery in 2026, with three frigates transferred within a year. Nearchos will later receive the Standard 2++ configuration, planned for April 2029.

FDI stands for Defense and Intervention Frigate, the name Naval Group uses for this frigate family. The article describes the Greek ships as combat-ready vessels and emphasizes their sensors, weapons, communications, and support arrangements. Their purpose is to provide the Hellenic Navy with capable ships for operations at sea.

A frigate typically combines air-defense, anti-ship, surveillance, and self-defense functions. It can escort other ships, monitor surrounding waters, and respond to aircraft, missiles, surface vessels, or other threats. The exact balance depends on its equipment and national configuration. The article identifies Greek additions such as Saab electronic warfare equipment, WiMAX/5G communications, a CAMCOPTER unmanned aircraft, and multiple weapon systems.

Nearchos shows how one FDI design can be adapted for a particular navy. Greece ordered four FDI HN frigates, with progressive upgrades from Standard 1 toward Standard 2++. The article does not provide a single formal mission list, but it links the ships to operational superiority and availability at sea.

The article’s visible text states that five FDI frigates are planned for France and four for Greece. It then cuts off after “four for Greece an,” so it does not provide the Swedish figure. The safest answer is therefore that France has five and Greece has four in the supplied material, while Sweden is unspecified here.

The article gives a clear delivery pace for the Greek programme. Naval Group delivered HS Kimon in December 2025 and HS Nearchos ten months later, on October 30. HS Formion was planned for the end of 2026. This means three Greek frigates were expected to be transferred within roughly a year.

The article also describes a total of 13 FDI frigates as planned across three navies, but the excerpt does not identify all three national allocations. Because the country breakdown is truncated, no reliable Swedish number can be extracted. The stated delivery schedule nevertheless demonstrates Naval Group’s rapid production for Greece.

Standard 1 already included several Greek-specific changes to the French FDI design. These included a Saab NLWS LWS/L-ESM, WiMAX/5G communications, S-100 CAMCOPTER integration, a 76mm gun with a Multi-Feed Device, and Leonardo LIONFISH 20 remote weapon stations instead of NARWHAL systems.

Standard 2 adds substantial defensive firepower. Nearchos receives two A50 SYLVER vertical-launch modules, four SYLENA Mk1 launchers that form the air-defense decoy system, and a 21-cell RAM close-in weapon system. Together, these systems expand the ship’s ability to launch missiles, confuse incoming threats, and engage threats at short range.

Nearchos is the first FDI HN frigate in Standard 2. It is planned to become the first in Standard 2++ configuration in April 2029. Later upgrades are expected to improve the SETIS combat-management system, sensors, electronic warfare, unmanned-aircraft integration, RAM missiles, and 76mm-gun ammunition.

Receiving more capable frigates can improve how the Hellenic Navy detects, manages, and responds to threats. The article specifically connects Nearchos’s capabilities with operational superiority at sea. Its upgraded configuration gives the ship more tools for air defense and close-in protection than the earlier Standard 1 arrangement.

The mechanism is layered combat power. Two A50 SYLVER modules provide additional missile-launch capacity, while four SYLENA Mk1 launchers support the ship’s air-defense decoy system. The 21-cell RAM system adds close-range defense. Sensors, electronic-support equipment, communications, and the SETIS combat-management system help coordinate those capabilities. The ship also uses a 76mm gun and other weapons.

These improvements could help frigates operate with greater resilience during demanding missions. The article does not promise a specific battlefield outcome. It does state that Nearchos will contribute to Hellenic Navy operational superiority, while future Standard 2++ upgrades should further improve sensors, electronic systems, unmanned-aircraft integration, and weapons.

The article presents the Greek FDI fleet as evolving from Standard 1 toward Standard 2++. Each stage adds or improves equipment while keeping the underlying frigate programme in place. This approach matters because capability can grow without restarting the entire shipbuilding effort for every improvement.

Nearchos illustrates the method. It begins as the first Standard 2 frigate, with additional A50 SYLVER launchers, SYLENA Mk1 decoy launchers, and a 21-cell RAM system. It is then scheduled to become the first Standard 2++ frigate in April 2029. Planned upgrades target SETIS, sensors, electronic systems, unmanned-aircraft integration, RAM missiles, and 76mm ammunition.

The article does not explicitly say that upgrades are cheaper or easier than replacement. It does show a continuing programme, an initial support contract, and cooperation with Greek industry. That arrangement supports maintenance and modernization while keeping the ships operational. A further Standard 2+++ remains a potential future development.

A frigate’s sensors first build an understanding of the surrounding environment. They can detect aircraft, ships, emissions, or other hazards. Electronic-support systems add information by monitoring signals. The ship’s combat-management system then combines these inputs, helps classify threats, and presents options to the crew. The article identifies SETIS as the FDI combat-management system.

Weapons provide different layers of response. Missiles launched from A50 SYLVER modules can address suitable air-defense or other targets. The 76mm gun and LIONFISH 20 remote weapon stations offer gun-based options. SYLENA Mk1 launchers provide decoys, while the RAM close-in weapon system protects the ship against nearby threats. Communications and the CAMCOPTER UAS can extend information and coordination.

In practice, these elements must share data and react quickly. The article says future upgrades will improve SETIS, sensors, electronic systems, and weapon capabilities. It does not describe every connection in detail, but the listed equipment shows a layered system rather than isolated weapons.
