Israel and Greece signed the largest defense agreement in the history of their relationship on Monday, a roughly $3.5 billion pact that will hand Athens a multi-layered, Israeli-built air defense network. The deal, finalized at Israel's Defense Ministry headquarters in Tel Aviv, comes as Turkey and Iran press increasingly aggressive postures across the eastern Mediterranean, and it marks a major step forward in the two nations' deepening strategic partnership.
The framework, known in Greece as "Achilles Shield," was signed by Israel Defense Ministry Director General Maj. Gen. (res.) Amir Baram and his Greek counterpart, Maj. Gen. Ioannis Bouras. Israeli officials called it one of the largest defense export agreements in the country's history and the biggest ever between Israel and Greece.
Under the agreement, Israel will build the Hellenic Armed Forces a fully integrated air defense array that draws entirely on Israeli-made systems. The package includes David's Sling missile defense batteries, Rafael's Spyder mobile air defense systems, and Israel Aerospace Industries' BARAK MX modular multi-layer air and missile defense platforms.
Multi-mission radars from IAI subsidiary ELTA Systems will provide the sensor backbone, while Rafael will develop a new national command-and-control system to tie the layers together. A separate agreement worth about $30 million covers Rafael's Drone Dome counter-drone systems.
Greek Defense Minister Nikos Dendias said the full array, which also integrates Heron unmanned aerial vehicles alongside other allied platforms, is expected to become fully operational within 35 months.
The timing is no accident. Greece has watched Turkey's assertiveness in the Aegean and eastern Mediterranean with growing alarm, while Iran's recent conduct has rattled the broader region. Israeli officials have framed the pact as a direct deterrent to both.
Israel Defense Minister Israel Katz said the two countries "share common strategic interests and face shared regional challenges." At a time when "actors with hegemonic ambitions are seeking to expand their influence and undermine stability in the region," he said, "Israel and Greece will continue to deepen their defense and strategic cooperation, and will act with determination to preserve stability and safeguard their security and shared interests."
Athens approved the procurement framework in July as part of a sweeping $31.8 billion military modernization initiative running through 2036. The agreement gives Greece a level of integrated air defense it has never had, anchored by systems with combat-proven track records.
The pact reshapes the eastern Mediterranean's security architecture. Israel, Greece, and Cyprus have steadily built closer defense and energy ties in recent years, and this deal solidifies that bloc at a moment of realignment across the region.
For Israel, it locks in a major European customer and expands its defense industry footprint at a time of surging global demand for proven air defense technology. For Greece, it delivers a shield built on systems that have performed in real combat, not just on paper.
Implementation will move quickly. Jerusalem will expand industrial defense cooperation with Athens, including transfers of knowledge and technology, while Israeli firms begin work on the multi-layer architecture.
The 35-month timeline means Greece could field a functioning national air defense network before the end of the decade -- a major upgrade for a NATO member that has long sought to close the gap with its neighbors. As tensions with Turkey and Iran persist, the "Achilles Shield" gives Athens something it has never had: a defensive umbrella built by one of the world's most battle-tested defense industries.
