Greece Approves $4 Billion Israeli-Built Air Defense Network, 'Achilles' Shield'

Greece's Government Council for National Security, known as KYSEA, approved a defense procurement package worth roughly €3.5 billion, about $4 billion, centered on Israeli missile defense technology, Defense Minister Nikos Dendias announced Thursday.

The centerpiece is a program called Achilles' Shield, a multi-layered air defense network meant to protect Greek territory from ballistic missiles, aircraft and drones with a single integrated command system. Dendias said the network will be "ready and fully operational within 35 months, starting from today," according to ekathimerini and reported by the Jerusalem Post.

The system leans heavily on Israeli hardware. The Jerusalem Post reported the package includes Rafael's Spyder system for short-range threats, Barak MX for medium-range interception, and David's Sling for ballistic missile defense, with radars from ELTA Systems, a subsidiary of Israel Aerospace Industries, tying the layers together. Reuters and Breaking Defense noted Greek and Israeli outlets have reported on this expected Israeli-heavy sourcing since at least November 2024, when the two countries began talks to replicate elements of Israel's air defense architecture.

Dendias made a point of saying this isn't simply Athens writing a check to Jerusalem. Some €700 million to €875 million of the package, by different outlet estimates, is earmarked for Greek industry, with Dendias telling reporters domestic companies will produce at least 25% of the system, according to Breaking Defense and Defense News.

Beyond the missile shield, KYSEA approved a broader shopping list. That includes 10 additional Shield AI V-BAT surveillance drones from the U.S., IAI Heron unmanned aircraft from Israel, three Embraer C-390 transport planes to be acquired from Portugal with first delivery expected next year, and small synthetic aperture radar satellites for sovereign imaging, according to the Jerusalem Post and Kurdistan24. Defense News additionally reported the approval of 10 British-built VICTA mini-submarines for special operations.

The dollar figures vary slightly across outlets, likely reflecting euro-to-dollar conversion timing and rounding. Breaking Defense put the air defense purchase at over $3.4 billion, while Defense News, the Jerusalem Post and Kurdistan24 each cited figures closer to $4 billion on a €3.5 billion base. The underlying euro figure, roughly €3.5 billion, is consistent across sources.

This procurement sits inside a much larger modernization drive. Greece plans to spend about €28 billion by 2036 overhauling its armed forces, a program that also includes up to 40 new F-35 fighter jets from the United States, according to Defense News, though the Jerusalem Post cited a figure of 20 F-35s, along with new frigates from France and Italy.

Athens' urgency here isn't abstract. Defense News noted Greece already spends nearly 3.5% of GDP on defense, well above the NATO average, a level driven by its long-running dispute with Turkey over maritime boundaries and energy exploration in the Aegean and eastern Mediterranean. Ankara has its own parallel air defense buildup underway, dubbed Steel Dome, which Breaking Defense flagged as part of a wider regional race among NATO members, including the U.S. push for its own Golden Dome, to field layered defenses against missile and drone threats.

The Greece-Israel relationship long predates this deal. The Jerusalem Post noted the two countries' security ties have deepened significantly since 2010, when Israel's relationship with Turkey soured, pushing Athens and Jerusalem into closer alignment. The two nations already run a joint air training center on Greek soil and hold annual military exercises. Last year, according to Defense News, Greece bought 36 Israeli-made rocket artillery systems for about €650 million, a deal the Jerusalem Post separately identified as involving Elbit Systems' PULS launchers, approved in April.

Defense analysts watching Greece's buildup have raised questions about whether relying so heavily on a single foreign supplier, however capable, for a national air defense backbone creates a dependency risk if political relations ever shift or supply chains get strained. Dendias's answer is embedding local production and requiring a quarter of the system be Greek-built. That's the standard hedge against such concerns, and it's a real commitment tied to specific contract terms rather than a vague promise.

The specific breakdown of which systems fall under which contract value is not yet public, nor is there a unit-by-unit accounting of the roughly $600 million discrepancy between Breaking Defense's figure and the other three outlets. Dendias has said deliveries will happen "in stages" over the 35-month buildout. Whether Achilles' Shield hits its operational deadline, expected sometime in 2029, and whether the promised 25% domestic production materializes as contracts are finalized will be the measure of this announcement.
