European Drone Defence Initiative (EDDI): Building Europe’s Counter-UAS Architecture

The European Drone Defence Initiative (EDDI) emerges from the institutional and strategic architecture of the Defence Readiness Roadmap 2030, which operationalises the vision set out in the White Paper for European Defence – Readiness 2030. Conceived at the intersection of technological sovereignty and deterrence credibility, EDDI is the European Union’s first collective response to the rapid proliferation of unmanned aerial systems as instruments of warfare, surveillance, and coercion. The White Paper defines the transformation of airspace into a contested operational environment, highlighting how Russia’s full-scale invasion of Ukraine and its extensive reliance on drones for reconnaissance and precision strikes exposed Europe’s systemic vulnerability to low-cost, high-impact technologies. This awareness prompted the European Council in June 2025 to request a defence roadmap centred on readiness, industrial resilience, and shared capability development. Within that framework, the Commission and the High Representative identified four European Flagships — the Drone Defence Initiative, the Eastern Flank Watch, the European Air Shield, and the European Space Shield — as operational anchors of a continental deterrence posture. EDDI represents the most immediate and technologically dynamic of these programmes, linking the lessons learned in Ukraine with the EU’s ambition to ensure interoperability with NATO while asserting industrial independence in critical defence technologies. It symbolises Europe’s strategic shift from fragmented procurement to coordinated readiness, transforming the defence of airspace into a cross-domain policy integrating innovation, production, and alliance coherence.
