One or two drones reportedly overflew Denmark’s Karup airbase on Wednesday evening, marking a significant escalation in what Danish officials are calling a coordinated “hybrid attack”.
The alleged drone overflight of Denmark’s primary military installation represents a concerning expansion of the ongoing crisis that has already forced the closure of multiple airports and prompted Denmark to alert NATO and the European Union about what Prime Minister Mette Frederiksen has called “the most serious attack on Danish” infrastructure.
The reported drone incident at Denmark’s largest military base adds a new dimension to the crisis, suggesting that the perpetrators are systematically probing both civilian and military critical infrastructure. The Danish Defence Command supports the Police with relevant capabilities in connection with drone observations in the vicinity of critical infrastructure and military installations.
Suspected drone activity disrupted Denmark’s Aalborg airport for the second time within 24 hours on Thursday evening, after Copenhagen alerted NATO and the EU over a similar “hybrid attack” the day before. The military base incident fits into this broader pattern of coordinated operations.
Several unidentified drones shut down airspace over Copenhagen Airport on Monday night, prompting concerns that Russia could be behind the flyover above Scandinavia’s largest airport, marking the beginning of what has become a multi-day crisis.
Coordinated Infrastructure Targeting
Danish officials believe drone flyovers at 4 airports meant to sow fear, and the addition of military base overflights suggests a comprehensive campaign designed to demonstrate vulnerabilities across Denmark’s critical infrastructure network.
The systematic targeting of both civilian aviation and military installations indicates a level of coordination and intelligence that points to state-level involvement rather than criminal or terrorist activities.
Russian Naval Presence
Adding to security concerns, a Russian naval vessel was caught lurking off Denmark’s coast with its tracking equipment deactivated, indicating the vessel wished to avoid detection by Danish authorities. This maritime presence coinciding with the drone incidents raises questions about coordinated operations.
The presence of Russian naval assets in Danish waters during the ongoing drone crisis suggests potential command and control or logistics support for the aerial operations.
