Belgium Deploys Military Drone Jammers to Protect Key Sites
Belgium has taken a major step in defending its most sensitive facilities against aerial threats. On Friday, the Council of Ministers approved a draft law allowing operators of critical infrastructure to use military-grade drone jamming technology previously reserved exclusively for the police, armed forces, intelligence services, and NATO. The decision, proposed by Telecommunications Minister Vanessa Matz, marks a significant expansion of the country’s counter-drone capabilities in response to a sharp rise in suspicious drone incursions since October 2025, as reported by DH Les Sports.
Context: A Nation Under Drone Surveillance
The decision comes after a series of alarming drone incursions that exposed Belgium’s vulnerability to aerial espionage and hybrid warfare. In October 2025, unidentified drones were spotted over the Elsenborn military training camp near the German border. The situation escalated dramatically in early November, when multiple drones were sighted over Kleine-Brogel airbase—a facility widely reported to host US nuclear weapons as part of NATO’s nuclear sharing program—and Brussels Airport, forcing flight suspensions.
Defence Minister Theo Francken described the incidents as “espionage” and publicly attributed them to Russian intelligence activities, part of a broader pattern of hybrid warfare against European nations. The National Security Council convened on 6 November 2025, and the Council of Ministers tasked Minister Matz with drafting legislation to expand the legal use of drone jamming technology, as The Brussels Times reported in December 2025.
Who Gets the Jammers?
Under the new law, four categories of critical infrastructure operators can apply for authorization to deploy drone jamming systems:
- Nuclear installations
- Prisons
- Seveso sites (industrial facilities handling dangerous substances)
- European institutions established on Belgian territory
Each application must be approved by the Belgian Institute for Postal Services and Telecommunications (IBPT), the country’s telecommunications regulator. Operators must conduct a prior risk analysis, and any activation of jamming equipment must be reported to the IBPT within two hours.
Balancing Security and Safety
Drone jamming technology works by disrupting radio frequency communications, which can neutralize malicious drones but also carries significant risks. Minister Matz acknowledged these dangers, stating that jamming “can disrupt emergency communications, medical equipment, and air navigation. Its use therefore remains, in principle, unacceptable in a civilian environment.”
She emphasized the careful balance the law seeks to strike: “We want to be able to neutralize threats, but only when necessary and when the benefits to society outweigh any negative consequences. That is the balance sought with this bill.”
Use of jamming is only permitted when the benefits clearly outweigh potential negative consequences for third parties. The IBPT conducted a public consultation before the draft was finalized, reflecting a commitment to transparent rule-making.
The €50 Million Procurement Controversy
The expansion of jamming authorization unfolds against a backdrop of political controversy over Defence Minister Theo Francken’s emergency anti-drone procurement. In November 2025, Francken rushed through a €50 million purchase of anti-drone systems—including rifles, directional jammers, BLAZE interceptors, and radar detection systems—using an urgent procedure without a public tender.
A VRT investigative report in April 2026 raised serious questions about how five companies were selected and the use of the urgent procedure. A judicial investigation was opened. The federal internal audit service twice refused to conduct an audit, citing the complexity of the case and the ongoing judicial inquiry.
On 11 June 2026, the Chamber of Representatives voted unanimously—with abstentions from Ecolo and DéFI—to ask the Court of Audit to investigate the legality of both the €50 million anti-drone purchase and a related €90 million equipment purchase for Ukraine, as reported by RTBF and La Libre.
Broader European Context
Belgium is not alone in facing drone threats. Across Europe, countries have been grappling with similar challenges. France has deployed anti-drone systems for major events and nuclear sites. The Netherlands has experimented with electronic countermeasures. The United Kingdom has deployed military-grade counter-drone systems at airports. The European Union has been working on harmonized counter-drone regulations.
Belgium’s location—hosting major EU institutions and NATO headquarters—makes it a particularly attractive target for intelligence-gathering drone operations. The inclusion of European institutions as protected entities under the new law underscores this unique vulnerability.
What’s Next
The draft law must still complete its legislative journey before entering into force, meaning further amendments are possible during parliamentary debate. Key questions remain: What specific jamming technologies will be deployed? How will the IBPT ensure compliance with strict usage conditions? And will the Court of Audit investigation into the €50 million procurement affect the rollout of this new policy?
A first report from the Court of Audit could be ready by October 2026, with a definitive version expected in December. Meanwhile, Belgium’s critical infrastructure operators may soon have a powerful new tool to defend against the growing drone threat—one that comes with both significant security benefits and serious responsibilities.
