Tel aviv: Greece is set to sign a $3.6 billion deal Monday to acquire three Israeli air defense systems, according to Israeli media reports. The Jerusalem Post said a Greek delegation will sign the agreement with the Israeli Defense Ministry in Tel Aviv following nearly three years of negotiations.

According to Anadolu Agency, the deal covers the David's Sling, Spyder, and Barak MX systems, which are expected to be incorporated into Greece's planned multi-layered Achilles Shield air defense network. Israel's Rafael is expected to receive the largest share of the contract, supplying David's Sling, designed to counter ballistic and other heavy missile threats, as well as the mobile Spyder system for drones and other airborne threats.

Israel Aerospace Industries will supply the Barak MX system, designed to intercept aircraft and missiles, according to the newspaper. The project also includes a nationwide command-and-control network linking the systems and coordinating interceptions. The network is expected to use artificial intelligence to process information from radar and sensors, classify threats, and select the appropriate interception system.

Spyder batteries are expected to be deployed on Greek islands, while Greek defense companies are set to receive around £700 million ($820 million) in work under the project. Israeli financial daily Calcalist and news website Yedioth Ahronoth reported Friday that the £3.1 billion ($3.6 billion) project would be implemented in stages over roughly 35 months.

The Achilles Shield network is expected to connect Greece's existing air defenses, including Patriot systems, with David's Sling, Spyder, and Barak MX under a unified network. Calcalist said 12 Greek companies would account for at least 25% of the project after Athens sought greater domestic participation and technology transfer during negotiations. The talks also covered Greek access to the systems' software source code, which would give Athens greater autonomy in future maintenance and upgrades, according to the newspaper.

Greek daily Kathimerini also reported Friday that the deal is worth around $3.6 billion and is expected to be signed Monday. If signed at the reported value, the deal would exceed Israel's $3.5 billion sale of the Arrow 3 missile defense system to Germany in 2023. Neither Greece nor Israel had officially confirmed the agreement as of Sunday evening.
