Israel to Supply Greece with Air Defense System, Withholding Source Code

Greece will not receive the source code for the "Achelis Shield" air defense system it is purchasing from Israel for approximately 3 billion euros, according to Politico. The source code is the underlying software that operates the system, and access to it would allow Greek engineers to maintain, modify, and upgrade the system in the future without complete reliance on Israeli suppliers. Greek Defense Minister Nikos Dendias stated in July that becoming "hostages" to any country, even a friendly ally, is "completely impossible."

The Achelis Shield, agreed upon by Israel and Greece in late August, is intended to integrate several Israeli technologies into a single system to defend Greece against missiles, aircraft, and drones. This deal is part of a broader deepening of security cooperation between Israel and European nations. However, the dispute over the software highlights the dilemma countries face when relying on foreign weapons systems for critical security needs.

Greece desired not only to purchase the system but also to ensure its own long-term operational and developmental capabilities. Israel, however, clarified that the Israeli source code is not part of the deal. Moshe Patal, head of the "Homa" (Wall) directorate at the Ministry of Defense, confirmed that Greece would not receive access to the source code as it was not included in the licensing agreement.

The Ministry of Defense has proposed a solution where Israeli knowledge will be transferred to Greek companies involved in the project, enabling them to develop their own Greek source code for the system, which will be under exclusive Greek control. This approach aims to balance Israel's need to protect its sensitive defense technology with Greece's desire for local capabilities to avoid complete dependence on Israel for future modifications or upgrades.
