Denmark's Minister of Defence Jeppe Bruus presented a bill on 5 November instructing the Danish Defence (Forsvaret) to detect, identify and track unmanned vehicles at sea and in the air. The background includes the drone observations in Danish airspace in September 2025. This is stated in bill L 95 in the Folketing (the Danish parliament).
The situational picture is to be shared with other authorities, primarily the police. According to the proposal, a widespread, layered and fine-meshed sensor network is expected to be built out across the entire country, including active radars as well as optical and acoustic sensors. According to the Danish Ministry of Defence, experience from Ukraine shows that effective detection requires several types of sensors.
The equipment will primarily be placed on military and public land. If voluntary agreements cannot be reached, the Danish Defence can order private property owners to grant access, though not at residential properties, preschools, schools, hospitals or care homes for the elderly. Owners and operators of critical infrastructure may also be required to share data from their own detection equipment. The Danish Defence will compensate for the costs incurred.
Anyone who refuses access, does not share data, or disrupts or removes the equipment can be sentenced to fines or, in cases of intent, imprisonment for up to two years. The activity is also exempted from the Danish Frequency Act and the Act on Radio Equipment, since the sensors may interfere with other equipment.
Information may also be shared with foreign authorities, for example in cooperation with neighbouring countries or NATO allies. Costs are to be covered within the existing budget framework of the Danish Ministry of Defence. The law is proposed to enter into force the day after its promulgation.
