Greece is entering a new era of naval strength, as the Hellenic Navy undergoes a sweeping modernization under a 12-year defense program that is set to reshape the balance of power in the Aegean and the Eastern Mediterranean.
By the early 2030s, the Greek fleet will include eight state-of-the-art frigates — a mix of FDI HN (Belharra) and FREMM — while the Navy’s four Hydra-class (MEKO 200HN) frigates will be fully upgraded to meet modern operational demands.
This is one of the most ambitious naval renewal programs in Greek history, aimed not only at renewing the fleet but at securing strategic superiority in an increasingly volatile regional environment. The FDI HN frigates, currently being built in France, feature SeaFire AESA radars, SETIS combat management systems, and the ability to launch ASTER 30 long-range surface-to-air missiles.
Each Belharra-class frigate can carry up to 32 ASTER 30 missiles, meaning the Hellenic Navy will field a total of 192 long-range interceptors — capable of defending vast sections of the Aegean and Eastern Mediterranean. With a range of up to 120 km, these systems can simultaneously engage multiple aerial threats, from fighter jets to cruise missiles.
Meanwhile, the government has approved a comprehensive modernization of the four Hydra-class frigates, equipping them with new combat management systems, upgraded radars, modern sensors, and enhanced anti-air and anti-ship missiles. This upgrade will extend their operational life by at least 15 years, making them fully compatible with the Navy’s new integrated operational doctrine.
The combination of FDI, FREMM, and upgraded MEKO frigates will create a core fleet of 12 high-capability surface combatants, interoperable with Type 214 submarines, MH-60R Romeo helicopters, and new unmanned surface and aerial systems. This multi-layered force structure will enable Greece to conduct the full spectrum of missions — from deterrence and air defense to surveillance, anti-submarine warfare, and blue-water operations.
Military analysts describe the addition of FDI HN and FREMM frigates as a quantum leap, restoring Greece to the ranks of the most technologically advanced naval powers in NATO. These vessels embody “digital ship” technology, integrating sensors and weapons through a unified network and linking seamlessly with Army and Air Force systems. In effect, the Hellenic Navy becomes a digital pillar of deterrence, embedded within Greece’s joint defense grid.
The choice of ASTER 30 missiles is also strategic: they form the backbone of Europe’s naval air defense, used by France, Italy, and the United Kingdom, and provide area defense — protecting not just the ship but friendly forces across a wide radius. In combination with SeaFire radars, they create a formidable aerial shield, giving Greece a decisive advantage amid rising regional uncertainty.
The 12-year modernization plan, due for completion by the early 2030s, marks the most significant fleet renewal since the 1980s. It is a strategic investment that goes beyond procurement — ensuring Greece’s maritime dominance and reinforcing stability in a region vital to Europe’s energy security and geopolitical balance.
