HS Kimon is the first of the new FDI HN (Belharra) frigates being built by Naval Group for Greece, under the agreement that opened a new chapter in Greek–French naval cooperation. The program has already set the pace on Lorient’s production line, with the second ship, HS Nearchos (F‑602), following, and the third, HS Formion (F‑603), having already passed its own major construction milestones.

The FDI HN was designed as a multi‑role frigate with a strong digital footprint, high automation, and sensors operating within a unified system. At the heart of its architecture lies a next‑generation AESA radar and a combat‑management philosophy that emphasizes rapid reaction, resilience against electronic threats, and continuous situational awareness—even in a “noisy” operational environment.

In terms of armament, the Greek configuration is heavy for its class. The package includes robust area air defense with Aster missiles, anti‑surface strike capability with Exocet, and complementary point defense with RAM, ensuring the ship does not rely on a single “layer” of protection. The message is clear: Kimon is not coming merely for escort duties, but to operate as an air‑defense hub and a deterrence platform, with capabilities that shift the balance in high‑intensity scenarios.

The operational capabilities of HS Kimon (F‑601) place the Hellenic Navy on a different scale of power and combat perception, as the FDI HN frigate was designed from the outset for high‑threat, multi‑axis environments with intense electronic activity. This is not an escort ship, but a platform capable of functioning as a central hub for air defense, surveillance, and command in long‑range naval operations.

At the core of its operational philosophy is area air defense. Kimon can detect, track, and engage multiple aerial targets simultaneously—from fighter aircraft and UAVs to cruise missiles and saturation attacks. This capability allows it to protect not only itself, but an entire naval force or critical maritime areas, creating a long‑range air‑defense “umbrella.”

At the same time, the frigate possesses strong anti‑surface warfare capability, able to threaten surface targets at long ranges with high precision and simultaneous engagements. This gives it a deterrent role and the ability to control maritime zones, especially in areas of intense naval activity such as the Aegean and the Eastern Mediterranean.

Significant emphasis has also been placed on anti‑submarine warfare. HS Kimon can operate both as an autonomous unit and as part of an ASW group, leveraging sensors, sonar systems, and a helicopter to detect and track submarines at great depths and distances. This capability is critical in an environment where submarines represent one of the most difficult and dangerous threat factors.

In terms of self‑protection, the ship is designed to withstand saturation attacks and asymmetric threats. It features multi‑layered defense against missiles, fast attack craft, and low‑altitude aerial threats, while its advanced electronic suite enables it to detect and counter jamming, electronic attacks, and attempts to deceive sensors.

A decisive advantage of HS Kimon is its digital architecture. All combat systems, sensors, and weapons operate as a single integrated whole, enabling extremely rapid decision‑making and the sharing of the tactical picture with other Fleet units, the Hellenic Air Force, and allied forces. This transforms the frigate into a floating command center, capable of coordinating complex operations in real time.

Finally, the operational flexibility of HS Kimon allows it to undertake missions ranging from pure combat operations to surveillance, deterrence, control of sea lines of communication, and participation in international missions. In simple terms, F‑601 does not merely add a modern ship to the Fleet—it introduces a new philosophy of naval warfare, with an emphasis on network‑centric operations, deterrence, and dominance at sea and in the air.
