Across Europe, drones keep forcing airports to halt or reroute traffic, and the pattern is no longer being dismissed as bad luck or careless hobbyists. Security officials now talk about a sustained campaign of incursions that tests how far unmanned aircraft can push into critical airspace before someone reacts. The incidents are scattered on the map, but the targets and timing suggest a deliberate probing of Europe’s ability to keep its skies safe.
What is emerging is a messy, uneven response that mixes emergency airport shutdowns, hurried radar purchases and quiet intelligence work. I see a continent trying to adapt on the fly to a technology that is cheap, hard to trace and increasingly woven into military strategy from Russia to Ukraine, even as civilian aviation rules struggle to keep up.
From isolated scare to named phenomenon
European officials have moved from treating drone disruptions as one-off scares to recognising a broader pattern of unexplained flights. The cluster of incidents has become significant enough to be described collectively as the 2025 European drone sightings, a label that reflects how frequently unmanned aircraft are now reported near sensitive sites. That framing matters, because it signals that governments see a systemic security issue rather than a string of aviation nuisances.
Officials are still cautious in public, but the language has sharpened as more incursions are logged. Reports describe drones appearing over airports, military locations and other infrastructure, often in low light when they are harder to track. In several cases, authorities have acknowledged that they do not yet know who is flying these systems or why, only that the activity is persistent enough to demand a coordinated response across European airspace.
Airports on the front line of a drone problem
Commercial hubs have become the most visible victims of this new reality, because any drone near a runway can shut down operations within minutes. A live report from Pra Prague captured how quickly a suspected drone sighting can ripple through the system, with flights held on the ground and passengers stranded while airspace is checked. The disruption is not just an inconvenience, it is a reminder that a small unmanned aircraft can paralyse a major airport at peak time.
Industry specialists warn that this is not a passing phase. One detailed assessment of Drones and airports notes that infringements near runways have been building for years and are now intersecting with busier travel seasons, such as the Octoberfest period in Germany. That combination of higher passenger volumes and more drone activity raises the stakes for every false alarm, because even a short closure can cascade into missed connections and diverted aircraft across the continent.
Denmark, Norway and the first wave of airport shutdowns
The shift from nuisance to national security issue became impossible to ignore when drones forced repeated disruptions in Scandinavia. Between September 22 and September 25, a flash report on Denmark and Norway documented how sightings near airports in both countries triggered operational changes, including temporary halts to flights. Those few days showed how quickly a handful of unmanned aircraft could affect cross-border travel and freight.
In Denmark, the political reaction was immediate. Prime Minister Minister Meta Friedrien publicly described a drone incident at Copenhagen’s airport as a “serious attack”, language that underlined how authorities now view incursions near runways as potential acts of aggression rather than mischief. That framing has influenced how other governments talk about similar events, pushing them to treat unexplained drones as part of a wider security challenge rather than a purely aviation problem.
Germany’s 1,000 suspicious flights and a broader airspace picture
Nowhere illustrates the scale of the issue more starkly than Germany. Federal authorities there have registered over 1,000 suspicious drone flights in 2025, a figure that includes both confirmed incursions and unexplained radar tracks. That number is large enough to suggest that what is being seen at airports is only a slice of a much wider pattern of unmanned activity across German airspace.
Further detail from another report notes that there have been Over 1,000 suspicious drone flights recorded in Germany in 2025, with 202 cases considered particularly concerning by investigators. Those figures, cited by Holger Münch of the Bundeskriminalamt, show that the problem is not confined to a few headline-grabbing airport closures but extends to a steady drumbeat of unexplained flights that test how well authorities can detect and attribute unmanned aircraft.
Russia, hybrid pressure and the suspicion behind the controls
As the incidents have multiplied, attention has turned to who might be orchestrating at least some of them. A detailed analysis of hybrid activity across the continent notes that Novaya Europe has catalogued airspace violations and other pressure tactics, with Russian-linked operations featuring prominently in the list. That work places drone incursions alongside cyberattacks and sabotage as tools used to unsettle European states without crossing the threshold into open conflict.
Publicly, several governments have gone further. One widely cited briefing on mysterious activity notes that Drones are appearing above airports, military sites and other infrastructure, and that Russia is the chief suspect behind at least some of the activity. European officials quoted elsewhere have echoed that view, with one assessment stating that European officials have said that they believe Russia is behind at least part of the wave of drone sightings in Europe. None of this proves a single, centrally directed campaign, but it does show that suspicion is coalescing around a familiar actor.
Airports are not the only targets
While runways grab the headlines, the same drones are probing other parts of Europe’s critical infrastructure. In Belgium, a detailed account of a Pattern of Drone Intrusions describes how between three and five unmanned aircraft were observed over a nuclear plant on a single evening, even as operations continued. That incident, and others like it, has forced regulators to think about drones not just as a threat to aircraft but as a way to surveil or intimidate energy facilities.
Concerns about nuclear safety are now continent-wide. A recent assessment of how reactors are preparing for 2026 notes that But it is not just the French and Irish incidents that are setting off a wave of concern over Europe, with reports of drones near nuclear sites in Belgium, as well as Germany and Scandinavia. That spread of targets reinforces the idea that whoever is behind at least some of these flights is interested in a broad picture of European resilience, not only in disrupting passenger jets.
Belgium’s airports and the NATO angle
Belgium has found itself at the centre of this story because it hosts both major airports and key institutions. A detailed List of Airports affected by drones highlights that Brussels and Liège airports in Belgium faced overnight disruptions after unmanned aircraft were reported in their vicinity. Those incidents underscored how quickly drone sightings in a relatively small country can affect traffic across the wider European network.The security response has been shaped by Belgium’s role in NATO. A recent defence procurement announcement explains that a new radar purchase closes a critical sensing gap and strengthens protection for sensitive sites in a country central to NATO, particularly against small low flying unmanned aircraft. That investment shows how a series of disruptive but non-lethal incidents can accelerate spending on counter-drone technology, with alliance planners keenly aware that a successful strike on an airport or headquarters would have political as well as operational consequences.
Why officials say this is not random
Security professionals are increasingly explicit that they see a pattern in how and where drones are appearing. One senior aviation voice warned in early autumn that a Pattern emerging of EU airports disrupted by drones should be read as a warning about the future nature of threats to aviation. The argument is that repeated incursions at different hubs, often during busy travel periods, look less like coincidence and more like a methodical test of procedures and response times.
That view is reinforced by how the incidents cluster around sensitive infrastructure. A broader briefing on unexplained activity notes that European officials have said that they believe Russia is behind at least some of the incursions, even though no drone has been recovered that definitively proves that link. The absence of hard forensic evidence has not stopped intelligence services from treating the pattern as deliberate, in part because it fits with other forms of hybrid pressure that have targeted pipelines, cables and political institutions.
What kind of drones are we really seeing?
One of the most unsettling aspects of these incidents is how little the public knows about the hardware involved. A detailed technical explainer notes that They are not believed to be flown by hobbyists and appear more sophisticated than commercially available drones, with capabilities that suggest custom builds or military-grade systems. That assessment helps explain why so few have been intercepted or recovered, and why radar and radio-frequency sensors sometimes struggle to track them.
The technology is evolving quickly, shaped in part by the war between Russia and Ukraine, where both sides have used one way attack and decoy drones at scale. One recent report highlights that Ukraine testing drones immune to jamming systems could change security measures worldwide, because traditional countermeasures rely heavily on disrupting control links. If similar resilient designs are adapted for covert flights over European infrastructure, the challenge for airport security teams will become even more complex.
How Europe is trying to catch up
Faced with this mix of mystery and risk, European states are scrambling to upgrade their defences. The Belgian decision to buy new mobile radar that closes a critical sensing gap is one example of how governments are trying to spot small low flying unmanned aircraft before they reach runways or reactors. Similar investments are being discussed in other capitals, often framed as part of broader NATO efforts to harden critical nodes against hybrid threats.
At the same time, regulators and airport operators are revisiting procedures that were written for a different era. Guidance that once focused on keeping traditional aircraft separated is being rewritten to account for small drones that can appear with little warning. Industry analysis of Drones and airports stresses that detection is only half the battle, because authorities also need clear rules on when to halt flights, how to communicate with passengers and how to restart operations without creating new safety risks.
The geography behind the headlines
Although the incidents are spread across Europe, certain locations keep recurring in official briefings and open source reporting. Major hubs such as Copenhagen Airport and Oslo’s main gateway have featured in discussions of the European drone sightings, with officials there not ruling out any possibilities about who might be responsible. Those airports sit at the edge of the Baltic region, where tensions with Russia are already high, which adds a geopolitical layer to what might otherwise be seen as purely aviation incidents.
Elsewhere, coastal and industrial sites have drawn attention. Locations such as Île Longue in France, the port city of Gdańsk in Poland and industrial hubs like Hamburg and Rotterdam are all part of the same strategic picture, even when specific drone incidents at those sites remain unverified based on available sources. Mapping these places alongside confirmed airport disruptions helps explain why security planners talk about a campaign that touches both civilian travel and the infrastructure that underpins Europe’s economy.
What comes next for Europe’s skies
For now, Europe is living with a kind of managed uncertainty. Airports from Oslo to Frankfurt and Munich must assume that any unexplained object near a runway could be part of a hostile probe, even if it later turns out to be a false alarm. That mindset is costly in terms of delays and diversions, but officials argue that the alternative, treating drones as random background noise, is no longer acceptable.
Beyond aviation, the same logic is being applied to ports, refineries and energy corridors. Strategic locations such as Kaliningrad, Murmansk and other nodes along Europe’s northern flank sit close to airspace where drones have been reported, even if specific incursions at those exact sites are unverified based on available sources. As long as unmanned aircraft remain cheap, hard to attribute and militarily useful, Europe’s airports will continue to feel the pressure first, and their experience will shape how the continent defends the rest of its critical infrastructure.
