Greece has signed a $3.5 billion Israeli air defense deal for the ‘Achilles Shield,’ a multilayered network designed to strengthen protection against missiles, aircraft and drones amid rising regional tensions
TEL AVIV — Greece and Israel signed a landmark defense agreement Sunday worth approximately €3 billion, or about $3.5 billion, to build a nationwide multilayered air-defense network known as the “Achilles Shield,” marking the largest defense deal in the history of relations between the two Mediterranean countries.
The agreement, negotiated over roughly three years, will provide Greece with an integrated network designed to counter a broad range of threats, including ballistic missiles, aircraft and unmanned aerial vehicles.
Israel’s Defense Ministry described the agreement as one of the largest defense export deals in the country’s history.
Under the contract, Israel will supply Greece with a network built around several of its most prominent air-defense systems, including Rafael Advanced Defense Systems’ David’s Sling and SPYDER platforms, as well as the Barak MX system manufactured by Israel Aerospace Industries.
“This is the largest defense export deal in the history of Israel-Greece relations and one of the largest in the history of the State of Israel,” Israel’s Defense Ministry said in announcing the agreement.
The deal transforms years of defense cooperation between Athens and Jerusalem into something considerably more ambitious: a national architecture intended to link different layers of air defense under a unified command structure.
For Greece, the agreement represents a major step in a broader modernization program designed to reshape the country’s armed forces for an era increasingly defined by missiles, drones and regional instability.
For Israel, it provides a powerful demonstration of the growing international demand for defense technologies tested and refined during years of conflict.
Building the ‘Achilles Shield’
The centerpiece of the agreement is a multilayered system intended to provide Greece with protection against threats operating at different altitudes and ranges.
David’s Sling, developed by Israel to intercept ballistic missiles and other long-range threats, will form one of the network’s principal layers.
The SPYDER system is designed to counter shorter-range aerial threats, including hostile drones and unmanned aircraft.
The Barak MX system, produced by Israel Aerospace Industries, provides another layer against aircraft and missiles.
The agreement also includes multi-mission radars produced by ELTA Systems, an IAI subsidiary, as well as a new national command-and-control architecture intended to consolidate Greece’s air-defense capabilities into a coordinated network.
Rather than operating as separate weapons systems, the components are designed to share information and respond through a unified operational structure.
That integration is at the heart of the program known in Greece as “Achilles Shield.”
Israel’s Defense Ministry said the project represents the first time it will supply a complete, integrated defense array to another country capable of addressing threats ranging from ballistic missiles to aircraft and hostile drones.
The name itself carries symbolic weight in Greece.
Achilles, the legendary warrior of Greek mythology, has long represented martial strength and resilience. Athens is now applying that symbolism to a modern defense architecture built around radar networks, automated command systems and advanced interception technologies.
Greek Defense Minister Nikos Dendias has described the program as a critical element of the country’s broader military transformation.
The “Achilles Shield,” he said, is part of Greece’s larger Agenda 2030 military reform program, which he characterized as moving the country’s armed forces into “a new reality” and introducing “a new approach to defense and deterrence.”
He called the project “an important link in the reform of the Armed Forces” and “a necessary response to the geopolitical and technological challenges of our time.”
A changing threat environment
The timing of the agreement reflects the rapidly changing security environment surrounding Greece.
Athens has long maintained significant defense spending because of tensions with neighboring Turkey, particularly over territorial waters, airspace and competing claims in the Eastern Mediterranean.
At the same time, developments farther east have underscored the growing importance of missile and drone warfare.
Iran’s extensive missile arsenal and the widespread use of drones in conflicts across the Middle East and Europe have transformed military planning in ways that were difficult to imagine only a decade ago.
The wars of recent years have demonstrated that traditional air defenses designed primarily to counter fighter aircraft are no longer sufficient.
Military planners increasingly require systems capable of detecting and responding to large numbers of low-cost drones, cruise missiles and ballistic missiles.
The Israeli Defense Ministry said the Greek network would draw on “the extensive operational experience Israel’s defense establishment has gained during the war.”
That operational record has become a central selling point for Israel’s defense industry.
Israeli-made systems have attracted growing international interest precisely because they have been deployed under real-world combat conditions against missiles, rockets and drones.
For Greece, the appeal is not merely acquiring individual weapons platforms. It is purchasing an integrated architecture built around the assumption that future conflicts will involve multiple threats arriving simultaneously.
Turkey looms over Eastern Mediterranean calculations
Although the official agreement focuses on strengthening Greece’s national defense, the geopolitical context is impossible to separate from the long-running rivalry between Athens and Ankara.
Greece and Turkey remain NATO allies, but their relationship has repeatedly been strained by disputes over maritime boundaries, airspace, energy exploration and territorial claims in the Aegean and Eastern Mediterranean.
The expansion of defense cooperation between Greece and Israel has become one of the most significant strategic developments in the region.
Athens, Jerusalem and Nicosia have strengthened military and security coordination in recent years, reflecting overlapping concerns about regional instability and the shifting balance of power in the Eastern Mediterranean.
Israeli Defense Minister Israel Katz emphasized the broader strategic dimension of the relationship after the agreement was signed.
“Israel and Greece share common strategic interests and face shared regional challenges,” Katz said. “At a time when actors with hegemonic ambitions are seeking to expand their influence and undermine stability in the region,” the partnership between the two countries carries increasing importance.
The agreement is therefore likely to be viewed beyond Greece’s borders as more than a conventional arms transaction.
It strengthens a security axis that has gradually emerged between Greece, Cyprus and Israel — three countries whose defense interests increasingly intersect across the Eastern Mediterranean.
A major victory for Israeli defense exports
For Israel’s defense industry, the agreement represents a major commercial and strategic milestone.
The €3 billion transaction is the largest defense export agreement ever concluded between Israel and Greece and ranks among the largest export deals in Israeli history.
The contract will benefit several major Israeli defense companies.
Rafael Advanced Defense Systems will provide David’s Sling and SPYDER systems, while Israel Aerospace Industries will contribute the Barak MX platform and other components.
The agreement also includes substantial industrial cooperation with Greece.
Greek companies are expected to participate in production, installation and long-term support, with earlier reporting indicating that approximately €700 million in work could flow to Greek subcontractors and defense companies.
That element is particularly important for Athens, which has sought not only to modernize its military but also to strengthen domestic industrial capabilities.
The agreement therefore combines procurement with technology transfer, maintenance expertise and long-term industrial cooperation.
Greece expands its military modernization
The Achilles Shield is part of a much broader effort by Athens to modernize its armed forces.
Greece has allocated significant resources to defense procurement in recent years and is pursuing an extensive modernization program that includes advanced fighter aircraft, naval capabilities and upgraded missile systems.
Reuters reported that Greece plans to spend approximately €28 billion on military modernization through 2036, including acquisitions such as F-35 fighter jets from the United States and new naval platforms from European partners.
The Israeli air-defense agreement occupies a particularly important position within that strategy because it addresses the protection of the country itself.
A modern military can acquire advanced aircraft, warships and ground forces. But without an integrated defensive network, critical infrastructure and population centers remain vulnerable to increasingly sophisticated aerial threats.
The Achilles Shield is designed to address that vulnerability.
Its command-and-control network will coordinate information from multiple sensors and systems, enabling Greek forces to build a more complete picture of potential threats.
The architecture reflects a broader transformation in modern warfare, where the speed of information processing has become almost as important as the physical capabilities of individual weapons systems.
From bilateral partnership to strategic architecture
Greece was already a significant customer of Israel’s defense industry before Sunday’s agreement.
Athens has acquired Israeli-made Spike missiles, SPICE precision-guided systems, Rampage missiles and Heron drones.
Earlier this year, Israel and Greece also signed a separate agreement worth approximately $750 million for the supply of PULS rocket artillery systems to the Greek armed forces.
The Achilles Shield agreement, however, takes the relationship to another level.
Instead of purchasing individual systems, Greece is now integrating Israeli technology into a national defense architecture.
That development is likely to deepen cooperation between the two militaries for years, requiring training, maintenance, intelligence-sharing and continuing technological support.
The strategic relationship between the two countries has expanded considerably since the early 2010s, driven by shared interests in energy security, maritime stability and defense cooperation.
The new agreement provides perhaps the clearest indication yet that the partnership has moved beyond diplomatic coordination into long-term strategic integration.
A new air-defense map for the Mediterranean
The Achilles Shield agreement arrives at a moment when air defense has become one of the fastest-growing priorities for militaries across Europe and the Middle East.
Russia’s war in Ukraine has highlighted the devastating impact of drones and missile attacks. Conflict between Israel and Iran has demonstrated the scale and complexity of modern missile warfare.
Across Europe, governments are reassessing whether existing defense systems can cope with the volume and variety of threats emerging from contemporary conflicts.
Greece’s decision to build a comprehensive, multilayered network reflects that new reality.
For Israel, the agreement provides a powerful export victory and reinforces its position as a major supplier of air-defense technology.
For Greece, it represents an attempt to ensure that its defenses evolve as rapidly as the threats surrounding it.
And for the Eastern Mediterranean, the €3 billion Achilles Shield is likely to be interpreted as a signal of a broader geopolitical transformation.
What began as a defense procurement agreement has become something larger: a strategic investment in a changing regional order, where missiles, drones, maritime disputes and shifting alliances are reshaping the security calculations of countries on both sides of the Mediterranean.
