Denmark Reports Overnight Drone Sightings Near Military Sites – 27 Sept 2025

Denmark Reports New Overnight Drone Sightings, Heightening National Security Concerns

On the night of 26 September 2025, Denmark’s armed forces confirmed a new wave of unidentified drone flights near several sensitive military installations, deepening concerns over the country’s national security. Officials described the incidents as part of an escalating pattern of aerial intrusions unfolding over recent days.

While the military withheld exact times and locations for security reasons, it confirmed that the drones were detected over “high-risk” facilities. Police sources indicated that Karup Air Base in western Denmark was a focal point of the sightings.

This latest development follows an earlier disruption at Copenhagen Airport, where drone activity temporarily halted air traffic. Danish authorities have described these incidents as “serious attacks on critical infrastructure” and suspect they may be part of a broader hybrid operation—a mix of physical and electronic actions designed to spread fear and instability.

Defense Minister Troels Lund Poulsen admitted that Denmark currently lacks fully effective counter-drone systems capable of neutralizing such threats. The government has stepped up consultations with NATO and European allies but has not yet invoked Article 4, which allows a member state to call for collective discussions if its security is threatened.

Danish media report that additional airports and military sites—including Aalborg, Esbjerg, Sønderborg, and Skrydstrup—have also experienced drone activity, suggesting a coordinated effort across multiple locations. Security analysts warn that if these operations are this systematic and technically advanced, they may involve state-level resources or sophisticated non-state actors.

Experts caution that continued drone incursions could target critical infrastructure, restricted airspace, and key government facilities. They recommend that Denmark rapidly deploy modern anti-drone technology, enhance coastal and aerial surveillance, and strengthen overall defensive capabilities. Authorities have urged citizens to report any suspicious aerial activity immediately.

The surge in incidents is unsettling not only Denmark but also the wider European region at a time of heightened political tensions and security challenges. Observers say the coming days will be crucial as Denmark, NATO, and European partners decide how to respond—and whether these mysterious drones are linked to a state actor or sophisticated non-state group.
