Tactical Hedging

In recent years, the Eastern Mediterranean has witnessed growing attention to air defence, maritime security and infrastructure protection. Against this backdrop, on 31 August 2026, Greece and Israel signed an agreement to develop an integrated air and missile defence network, known as ‘Achilles Shield’, at a cost of approximately €3 billion. The project aims to strengthen Greece’s capacity to detect and intercept aerial and missile threats through a unified early warning, command and control system.   The project forms part of the comprehensive modernisation of the Greek armed forces and does not replace Athens’ commitments within the North Atlantic Treaty Organization or its alliances with the United States and the European Union. The decision to establish this system reflects the changing character of regional military threats, particularly the growing reliance on unmanned aircraft and precision missiles, alongside the continuing development of Turkey’s defence industries in reconnaissance and unmanned maritime and aerial systems.   This analysis therefore examines the implications of the Greek–Israeli agreement and its place within military modernisation programmes. It assesses its potential impact on the deterrence balance between Greece and Turkey, as well as its implications for security cooperation and managing regional tensions in the Eastern Mediterranean in the period ahead.
