This paper examines the prospects for a European Air Defence Shield, focusing on the technological, political and industrial challenges in creating an Integrated Air Defence (IADS). The urgency for a unified system is underscored by Russia’s war of aggression and the growing threats from hypersonic missiles, drones and electronic warfare. The European Sky Shield Initiative (ESSI) marks an important step towards addressing these vulnerabilities but faces significant obstacles, including fragmented procurement and national priorities. The paper explores the potential of ESSI, its limitations and the broader need for an integrated European approach to air defence.
