Belgium lets nuclear sites jam drones

A drone comes towards the fence of a nuclear site. Sensors pick it up, guards raise the alarm, and the clock starts running. Belgium wants some protected sites to have a quicker answer: authorised jamming before police or defence teams can get there.

The change would allow selected operators to use anti-drone jammers under tight conditions, including at nuclear sites, prisons, Seveso sites, meaning hazardous chemical plants, and European institutions in Brussels. It would expand a tool now held mainly by police, defence and intelligence services. The experiment matters because Brussels is testing a question that will land elsewhere in Europe too: can drone defence be moved closer to vulnerable sites without creating a loosely controlled market in private interference?

Permission at the Perimeter

Jamming can cut a drone’s control, video or navigation link without firing at it. That makes it useful around crowded or sensitive sites. It also makes it dangerous, because radio spectrum is shared space. EU rules such as the Radio Equipment Directive and the European Electronic Communications Code treat harmful interference as something states must control.

Belgium is trying to keep the permission narrow. Operators would need incident-specific notice to BIPT/IBPT, the Belgian telecom regulator. They would also have to keep the jamming area and duration as limited as possible. The public benefit would have to outweigh the risk of disruption.

That moves state permission down to the fence line. It does not give operators a blank cheque. It gives them a controlled power when the drone is already close and the normal authorisation chain may be too slow.

The pressure came from repeated illegal overflights near airports, military sites and places linked to nuclear weapons storage. Belgium then launched a €50 million counter-drone push covering radar and portable jammers. The weakness was not only detection. Unexplained incidents around critical sites exposed the delay between seeing a drone, getting command approval and acting.

Industrial sites had already shown the gap. After suspicious drones flew over Thales Belgium, the company had detection capacity but could not lawfully interfere without the competent authorities. It could see the drones and warn about them while they were still overhead (EU Today, War Wings Daily).

Europe’s Uneven Map

Belgium’s move is more than national security housekeeping. The protected geography includes EU institutions, NATO-linked sites and infrastructure connected to sanctions enforcement. Belgium’s exposure is tied to NATO headquarters, EU institutions and Euroclear’s role in frozen Russian assets. A Belgian rule on jammers can therefore affect the practical security of European power centres, even while the law remains national.

That is the European problem in miniature. The Commission has a counter-drone action plan built around testing, shared tools and common performance work. Member states still decide who can actually activate force or interference. Euronews captured the limit: the EU can help coordination, but drone security remains mainly national.

France is moving in a similar direction. A French Senate text would allow vital operators, or their contractors, to use anti-drone equipment against imminent threats near protected sites. Germany is holding a tighter line. The Bundesnetzagentur treats jammers as generally unlawful interference.

Europe is making different choices between speed and control. Belgium and France are testing delegated site defence. Germany is staying closer to a state-centred model. The more drones appear near airports, ports, military facilities and energy sites, the harder that patchwork becomes to justify.

The Risk Left Open

The case for Belgium’s move is straightforward: drones move faster than ministries. A site operator may be the only actor close enough to act in time.

The risk is equally practical. A jammer can disrupt emergency communications, aviation systems or lawful radio services. A disabled drone may also crash outside the fence, moving the danger from the protected site to the public around it.

The real test will be in the details Belgium has not fully settled in public: who qualifies, whether operators need prior instruction or only notice, how activations are logged, who reviews them, and who pays if lawful jamming causes damage. Belgium is offering Europe a model for faster last-mile defence. It is also showing how easily drone security can run ahead of the legal wiring built to control it.
