Germany races to close drone defense gaps after airport security breaches

Three drones carrying military-grade explosives turned up near Leipzig/Halle Airport in August, and what they revealed about Germany's defenses was far more troubling than the drones themselves. The third discovery—a device found in a field outside the airport grounds with roughly 50 grams of Hexogen, a high-explosive compound used by militaries—suggested something larger than isolated incidents. German public broadcasters and major newspapers began asking whether authorities had disclosed the full scope of what was happening.

Chancellor Friedrich Merz acknowledged the vulnerability bluntly: Germany had become a target for what officials called hybrid attackers. The timing was pointed. Just days before the latest drone discovery, Interior Minister Alexander Dobrindt had opened a drone security research center in Saxony-Anhalt, a state adjacent to where the incidents occurred. The optics of cutting a ribbon at a defense facility while explosive-laden drones circled nearby airports was not lost on anyone paying attention.

The question that hung over the investigation was how such devices had reached the airport at all. One drone was found near a Ukrainian cargo plane, which sent suspicion toward Russia and prompted the Federal Prosecutor's Office to take control of the case. But the deeper problem was systemic. Germany's Federal Criminal Police recorded more than 1,000 suspicious drone flights in 2025 alone. In October of that year, drones had disrupted Munich airport for hours, stranding passengers and exposing what security analysts had been warning about for months: Germany lacked the sensor networks and real-time monitoring systems needed to detect slow-flying, low-altitude drones before they reached critical infrastructure.

The country's defense architecture was fragmented by design and by accident. When a drone appeared anywhere in Germany, responsibility fell first to whichever state police authority governed that territory—and Germany has 16 of them, one per state. Only when a drone approached a major airport or railway facility could federal police intervene. This meant precious minutes could pass while bureaucratic boundaries were sorted out. Security experts and opposition lawmakers, including Green Party member Irene Mihalic, a former police officer herself, called the arrangement a substantial danger to domestic security. They pushed for the federal police to take the lead on all drone defense matters.

The government was moving, but not fast enough for some. In December, Dobrindt had established the Joint Counter Drone Center in Berlin, where federal police, state police, intelligence agencies, and the armed forces were supposed to share information around the clock. Yet even this coordination hub could not prevent a drone from apparently reaching the tarmac at Leipzig airport and being discovered almost by accident. The European Association for Unmanned Aviation pointed out the obvious: real-time monitoring of lower airspace and mandatory electronic tracking of all aircraft via ADS-L radio systems were essential, and Germany had neither at scale.

There was also the question of who could actually shoot a drone down. German law kept that responsibility with police, not the military. The Bundeswehr, Germany's armed forces, warned that protecting even their own facilities across tens of thousands of kilometers of fencing was already a strain; adding 24/7 protection of civilian airports and train stations would create a false sense of security they could never deliver. In March, Germany amended its air security law to allow the military to shoot down drones outside military property in emergencies to prevent catastrophic disaster, but this remained a narrow exception.

Equipment was another gap. Airports had announced drone defense systems with considerable fanfare, but many of these turned out to be detection systems only—they could spot drones but not stop them. At some airports, even detection systems had not yet been installed. The German Police Union criticized the resource shortage bluntly: unsafe train stations, unsafe airports, and a police force forced to plead for funding and technology. The Interior Ministry responded that eight major airports—Frankfurt, Munich, Berlin, Düsseldorf, Hamburg, Cologne/Bonn, Stuttgart, and Leipzig/Halle—were being prioritized for mobile drone defense equipment, with deployment targeted for the end of the year. The federal police had also expanded their drone defense unit from 130 personnel across four locations to 300 personnel across eight locations, designed to respond quickly and flexibly when needed. Whether this would be enough remained an open question as autumn approached.
