European governments are accelerating work on counter-drone defenses as recent airspace incidents underline the difficulty of detecting and stopping small unmanned aircraft around military sites and critical infrastructure.
Officials across the continent are examining a mix of radar, electronic warfare, jamming and interceptor systems. The challenge is to build defenses that can respond quickly without creating unacceptable risks for civilian aviation or nearby communities.
The war in Ukraine has demonstrated how inexpensive drones can be used for reconnaissance and attack, while unidentified drone sightings elsewhere in Europe have raised concerns about espionage and disruption. Governments are also studying how lessons from the battlefield can be adapted to peacetime airspace.
European defense companies are competing to supply detection and interception technology, and NATO members have increased exercises focused on unmanned threats. Policymakers face a cost problem, however: using expensive missiles against relatively cheap drones is difficult to sustain at scale.
The emerging approach is therefore likely to rely on layered defenses, combining sensors with electronic countermeasures and lower-cost interceptors. Rules governing who may disable a drone in civilian airspace remain another important part of the policy debate.
