After a series of drone sightings disrupted operations at Munich Airport—forcing the diversion of around 26 flights on a recent Saturday—the question of who is piloting these unmanned aircraft has become urgent for German authorities. Figures from Deutsche Flugsicherung (DFS), the country's air navigation service, show 37 such incidents were recorded in the first quarter of this year alone. Yet in most cases, investigators cannot determine whether the operator is a hobbyist, a reckless pilot, or someone with hostile intent.
One German company believes it has a solution. Argus Interception, working with US radar manufacturer Echodyne, has developed a system designed to hunt down rogue drones and capture them in mid-air—without destroying them. The A1-Falke interceptor fires a net intended to entangle the target and bring it safely to the ground, preserving the drone intact for forensic examination. The interceptor carries two net payloads, allowing a second attempt if the first misses.
At a demonstration near Hamburg attended by Euronews and a small group of journalists, the system was put to the test. A target drone was launched across a training ground; the A1-Falke pursued it, and moments later a loud bang signaled the capture. Sven Steingräber, co-founder of Argus Interception, explained that the system was designed for situations where shooting a drone down is not an option—near airports, critical infrastructure, or in densely populated urban areas. “We set out to address a capability gap,” he said. “Our net system allows us to capture the drone, transport it away and place it exactly where we want it. That way, we can avoid harm to bystanders as well as damage to property.”
How the system works
Echodyne provides the detection and tracking, while Argus supplies the interceptor. Echodyne’s larger EchoShield radar detects an initial drone entering the area and tracks it with high fidelity, sending data to a command-and-control centre. A smaller radar, EchoGuard, performs the same role at shorter ranges. Once a target is identified, its position is relayed to the A1-Falke. Mounted on the interceptor itself is a radar called EchoFlight, which performs air-to-air tracking. “So once the interceptor drone is in the air, then it's going to go find the intruder drone and then start tracking it,” said Echodyne chief executive Eben Frankenberg. “And so the interceptor drone can then follow it.” The A1-Falke is piloted from the ground; artificial intelligence assists with the operation, but final decisions remain with human operators.
Steingräber argued that many people still underestimate the potential threat from drones over sensitive sites. “Modern wars often don't begin with the first shot being fired, but with the gathering of information,” he said. “Such drone flights over critical infrastructure can have major consequences. Operational procedures are filmed, supply routes are mapped and critical points are assessed for an adversary, allowing them to strike more effectively because they already have the information.”
Reports of drones over critical infrastructure, airports, and military sites in Germany have become more frequent since Russia's full-scale invasion of Ukraine. Until recently, responsibility for dealing with such incidents rested largely with the police; the German army was generally limited to responding over its own facilities. That changed last year when Germany amended its Aviation Security Act, allowing the armed forces to provide support if requested by state authorities and if civilian resources are deemed insufficient. Some in the industry argue that the current framework leaves operators of critical infrastructure with few tools to respond, and they are calling for airports, energy sites, and other sensitive locations to be given greater scope to use counter-drone systems themselves.
The development comes amid broader concerns about drone security across Europe. In Romania, a Geran-2 drone strike on an apartment block in Galați has heightened fears of civilian casualties, while Ukraine continues to strike Russian oil refineries using long-range drones. The A1-Falke system, by capturing rather than destroying rogue UAVs, offers a potential model for proportionate responses that avoid collateral damage—a capability that may become increasingly valuable as drone incursions multiply across the continent.
