Israel and Greece signed a €3 billion ($3.5 billion) defense deal on 2026-08-31 under which Israel will build a multi-layered air defense system for Greece. ^[1] Greece signed a $3.5 billion defence deal with Israel to provide its first integrated multi-layered air defence network by 2029. ^[2] Israel and Greece signed a defense agreement worth roughly $3.5 billion, or approximately €3 billion, in Tel Aviv. ^[3] The agreement, named Achilles Shield, will provide Greece with an integrated national air-defense network incorporating David's Sling, SPYDER, BARAK MX systems, MMR radars, and Drone Dome counter-drone systems. ^[4] Greece spends nearly 3.5% of its gross domestic product on defense due to a long-standing dispute with Turkey, and plans to spend about €28 billion by 2036 on the Achilles Shield anti-ballistic, anti-aircraft and anti-drone system, plus up to 40 F-35 fighter jets from the U.S. and frigates from France and Italy. ^[5] The agreement was negotiated over three years and is described by Israel as one of the largest in the country's history. ^[6] Greece, once an implacably hostile nation to Israel, is now turning to Israel for defense protection, contrasting with other European countries like Ireland and Spain that are boycotting Israeli products. ^[7] An Israeli defence ministry statement confirmed that engineers will set up an aerial defence shield for the Greeks. ^[8] For Israel, the agreement marks another major step in the global demand for its air defense technology following repeated missile and drone threats from Iran and its proxies. ^[9]
