JERUSALEM — Israel and Greece signed a $3.4 billion (€3 billion) deal for air defense systems today at the Israel Ministry of Defense headquarters in Tel Aviv.

Dubbed Achilles’ Shield in Greece, the multi-layered air defense system is expected to expand Israel’s industrial defense cooperation with Greece and shore up supply chains. The deal has been widely expected over the last several months.

In a statement, Greek Minister of National Defense Nikos Dendias called Achilles’ Shield “an important link in the reform of the Armed Forces and an imperative response to the geopolitical and technological challenges of our time.”

Dendias added that Achilles’ Shield will be “a holistic deterrence system.”

“Ships, aircraft, land assets, autonomous systems, new satellites, and more generally, every platform equipped with sensors, are integrated into a single network-centric architecture,” he said.
