Low-cost drone flights that disrupted civilian airports and breached airspace over NATO military sites housing U.S. nuclear assets are now attributed to a coordinated Kremlin operation launched from Russian-linked merchant vessels. The assessment, published by the UK-based International Institute for Strategic Studies, draws on automatic identification system maritime tracking data that placed Russian shadow fleet ships in close proximity to the incidents across a dozen member states and Ireland from August 2024 through February 2026.
The report identified 144 drone sightings inconsistent with recreational or Ukraine-war-related activity. Nearly half of those occurred over military bases, while 26 percent targeted energy facilities, ports, and other critical infrastructure. Civilian airports accounted for 18 percent of the intrusions. The drones consistently appeared at night or in early morning hours and matched descriptions of professional or military-style equipment, underscoring a deliberate surveillance and harassment campaign.
The vulnerability of European air defenses against low-cost drone incursions is laid bare by this pattern, which exploits commercial shipping as a mobile launch platform while the vessels profit from transporting sanctioned Russian crude.
For American interests, the incursions represent a direct challenge to U.S. nuclear deterrent posture on the continent. The repeated failures to intercept these drones reveal a defense gap that adversaries can weaponize with off-the-shelf technology. This comes as Washington continues to underwrite European security through forward-deployed assets, raising fundamental questions about allied investment in domestic defense capabilities while the American taxpayer shoulders the burden of NATO’s extended deterrence.
