Greece signs €3 billion Achilles Shield air defence deal with Israel

Israel and Greece signed a €3 billion ($3.5 billion) air defence contract at the Israeli Defence Ministry in Tel Aviv on 31 August. Israel's ministry called it the largest defence export deal it has ever struck with Greece and one of the largest in the history of the Israeli defence industry, after the Arrow 3 sale to Germany in 2023. Greece's Ministry of National Defence put the figure at €3.035 billion. A separate €26 million paper covers extra counter-drone kits.

Amir Baram, director general of Israel's defence ministry, signed with Lt Gen Ioannis Bouras, Greece's director general for defence investments and armaments. The programme is named Achilles Shield in Athens. It is meant to give the Greek armed forces a single architecture that can track and shoot at ballistic missiles, aircraft and small drones under national control.

The hardware list is specific. Rafael Advanced Defense Systems will supply David's Sling, the medium-range interceptor developed with US support, and the shorter-range SPYDER. Israel Aerospace Industries will supply Barak MX, with a published range of up to 150 kilometres, and multi-mission radars from its ELTA unit. Rafael will also build the national command-and-control layer. Greece is to hold the source code of that command system. Kathimerini, citing the Greek defence ministry after the signing, said about €750 million of work will go to 19 Greek companies, or at least 25 percent of the contract.

Why Athens is buying a whole stack

Greece already buys high-end kit from France and the United States. This contract makes Israel the third large supplier of expensive sensors and interceptors. Athens has published a wider plan to spend about €28 billion by 2036 on Achilles Shield, on up to 40 F-35 fighters from the United States, and on frigates from France and Italy. The 31 August signature is the air-defence slice of that plan, not the whole bill.

The timing is not only Greek. Israeli officials told Calcalist that the extra production run needed to fill the Greek order could ease the strain on Israel's own interceptor stocks after three years of high use. Yair Koles, head of the Defence Export Division, said the contract could help Israel rebuild inventories while it prepares for later fights. That is a rare public admission that export work and home magazines now share the same factory lines.

Negotiations ran for about three years. David's Sling recorded its first combat intercept in 2023 and has been sold to Finland. Romania bought SPYDER in a multi-billion-dollar deal in June. Barak MX already has other foreign customers. What is new is the packaging: Israel is selling a complete multi-layer array rather than a single battery type. The ministry said this is the first time it has exported a full stack covering threats from ballistic missiles down to small drones.

What the source code clause changes

Most air-defence sales leave the buyer dependent on the seller for software updates and for the rules that decide which track becomes a shot. Greece's demand for source code on the command system is an attempt to keep the last decision inside the Greek chain of command. It also creates a long industrial tie. The 35-month implementation clock, the 19 Greek firms and the promised transfer of know-how are how Athens hopes to turn a purchase into a production base that can later export.

The €26 million add-on is narrower. It covers Rafael Drone Dome systems and upgrades to kits already sitting in the eastern Aegean. That is the layer that deals with cheap drones rather than ballistic missiles. The two papers together tell you what Greek planners fear: a high-end strike they cannot stop, and a low-end swarm they cannot afford to waste large interceptors on.

Israel remains diplomatically isolated in large parts of the world. The Greek contract is evidence that isolation at the United Nations does not, by itself, close the order book for systems that have been used in combat. For Athens the test is different. In 35 months the batteries have to work together, the source code has to be in Greek hands, and the 19 local firms have to be doing more than painting boxes. If any of those three fail, Achilles Shield will be an expensive import with a Greek name.
