Danish airspace has been violated
For the second time in just one week, Danish airports have been forced to shut down airspace due to unauthorised drone activity.
First, Copenhagen Airports A/S was affected on Monday evening, and by Wednesday night and into Thursday, the phenomenon had spread to Aalborg Lufthavn, Billund Airport, Esbjerg Airport, Skrydstrup, Sønderborg Airport, and possibly over Bornholm.
Over an aggregated span of a few hours, these incidents affected more than 20,000 passengers, cancelled more than 100 departures, and cost millions of DKK due to delayed air traffic.
Danish politicians, media outlets, and police have described these incidents as attacks on critical infrastructure and assessed that the drones were controlled by a capable actor. And while reactions have been swift, concerns have risen surrounding the mitigation of drones prior to their entry into Danish airspace and disruption of critical infrastructure.
This week’s incidents have thus exemplified a foreseen security challenge in Denmark, to which the focus has shifted from finding the perpetrator to adapting the nation’s C-UAS architecture going forward.
In this context, BSS has readily available passive acoustic solutions which effectively detect UAS incursions such as these recent observations.
The Komodo, BSS’ C-UAS solution, is currently deployed in Ukraine, where multiple systems are effectively supporting the mitigation of Russian strike drones such as fibre-optic FPV drones and Shahed-type UAS variants.
Furthermore, as a cost-effective C-UAS solution, the Komodo’s price tag pales in comparison to the financial repercussions of shutting down air traffic and the potential destructive capacity which armed strike drones could have caused.
