Greece is preparing to sign a $3.6 billion defense agreement with Israel to build a new, advanced air and missile defense system. The agreement is expected to be signed in Tel Aviv on Monday, August 31, and will become one of the biggest defense deals in Greece’s history. The project is known as “Achilles’ Shield.” Its main goal is to give Greece protection against different types of threats, including ballistic missiles, cruise missiles, aircraft, drones and other aerial weapons. The system will combine several Israeli-made defense platforms. These include David’s Sling, produced by Rafael, which is designed to intercept heavy rockets and ballistic missiles. Greece will also receive SPYDER, another Rafael system designed to defend against aircraft and drones. Israel Aerospace Industries will provide the Barak MX, which is designed to protect against aircraft and missiles. The new Israeli systems will also be connected with Greece’s existing Patriot air defense systems and other military capabilities. A central command-and-control network will help Greek forces detect threats and choose the appropriate defense system. The network is expected to use artificial intelligence to help manage and coordinate the different systems. The agreement is also expected to benefit Greece’s own defense industry. Around 12 Greek companies are expected to participate, with more than €700 million of work going to Greek companies as subcontractors. This represents roughly 25% of the project’s value. Greece has been strengthening its military capabilities in recent years, particularly because of security concerns in the eastern Mediterranean. Athens and Ankara, both NATO members, have long-standing disputes over territory, airspace and maritime boundaries. The new defense network is therefore seen as an important part of Greece’s effort to improve protection of its mainland and islands. The deal also highlights the growing defense relationship between Greece and Israel. Greece has already purchased several Israeli military systems, including missiles, drones and precision weapons. Overall, Achilles’ Shield is expected to give Greece a modern, layered air defense system capable of responding to threats at different ranges, while deepening military cooperation between the two countries.
