Belgium Faces New Defense Challenges: Arctic, Drones, Cyber

Belgium is confronting a dramatically expanded set of defense challenges as it prepares to deploy troops to Greenland, send F-16 fighter jets to Iceland, and bolster its air defense capabilities against drone threats and hybrid warfare. The moves reflect a rapidly changing geopolitical landscape in which the country must adapt its military strategy to meet emerging security concerns.

According to RTBF, Belgium will send approximately 30 military personnel to Greenland and four F-16 fighter jets with about 100 personnel to Iceland as part of NATO missions. General Major Frédéric Linotte of Belgian Defense explained that the objectives are multiple, but first and foremost for Belgium to show itself as a reliable NATO ally and solid in its contributions.

Arctic Security and Strategic Presence

The Greenland deployment, scheduled for September 4-18, 2026, is part of NATO’s “Arctic Sentry” operation—specifically the “Arctic Shield” program—created after US President Donald Trump’s threats to annex Greenland. Belgium will participate alongside Canada, Denmark, France, Finland, the Netherlands, Slovenia, and Sweden.

The Iceland mission involves four Belgian F-16s stationed at Keflavik air base, protecting Icelandic airspace for one month. This is the second time in a year Belgium has undertaken this mission, as RTBF reported. Defense Minister Theo Francken expressed pride in the mission, noting that “Iceland is a NATO country, a brother country, and it’s very important to protect Iceland with air policing thanks to our F-16s.”

The Arctic region has become strategically important as climate change opens new maritime routes and makes previously inaccessible areas more reachable. Michel Liégeois, professor of international relations at UCLouvain, noted that “climate change opens new maritime routes that were previously temporarily or permanently blocked. Powers are anticipating these new routes.”

According to VRT NWS, the military presence on the island aims to counter the American argument that security in this strategic region is not sufficiently guaranteed. The mission also seeks to strengthen security in Greenland, Iceland, and the Arctic Ocean—a region attracting growing interest from nations such as Russia and China.

Drone Threats and Hybrid Warfare

Beyond Arctic deployments, Belgium faces immediate security concerns closer to home. Drone intrusions have been reported at Belgian military bases, including Marche-en-Famenne and Elsenborn, raising concerns about espionage and hybrid warfare. As Le Vif reported, four to five drones flew over the Marche-en-Famenne camp in October 2025, which Francken described as “a real alert for our Defense” and “an orchestrated operation against the heart of our army.”

Belgium is accelerating its national anti-drone plan, including better incident reporting, enhanced cooperation with SkeyDrone, and installation of sensors at military sites. Francken emphasized that “we must be able to neutralize foreign drones on our territory. The previous government bought far too few countermeasures. It is urgent to remedy this situation.”

Liégeois stresses that threats extend beyond conventional military conflict. “The risks are not immediately those of seeing Russian tanks on the Grand-Place in Brussels tomorrow morning,” he said. Disinformation, interference in democratic processes, cyberattacks, and destabilization attempts now form part of what he calls “expanded security.” General Linotte echoed this sentiment: “We must not become paranoid, but we must not be naive either.”

Strengthening Air Defense

Belgium has taken concrete steps to address these threats. In July, the country officially purchased multi-layered air defense systems with the Netherlands for a total value of 3.1 billion euros, including 10 NASAMS long-range batteries and 20 SkyRanger 30 systems specifically designed to counter drones. As RTBF detailed, Francken stated that “Belgium will, thanks to this joint purchase, equip itself again with a powerful air defense capability. This step is essential for the protection of our population and our critical infrastructure.”

The agreement also includes 14 GM200 radars produced by French company Thales and 54 command vehicles from Italian firm Iveco. Belgium will temporarily lease a minimal NASAMS capability from manufacturer Kongsberg starting in 2027 to establish an initial operational capacity more quickly.

European Defense Evolution

The broader context of these developments is a fundamental shift in European defense posture. At the NATO summit in Ankara in July, European allies demonstrated a new resolve. As 21news.be reported, Francken declared: “We are no longer doing this to please Trump, but from a regained European self-respect. This continent is our home. We must be able to defend it ourselves.”

Belgium has reached the NATO target of 2% of GDP for defense spending but will need to progress further to meet future objectives. General Linotte acknowledged a “considerable investment, recruitment, and capability development deficit,” while insisting that “Belgium is more ready today than yesterday and will be even more ready tomorrow.”

According to RTBF’s coverage of the Ankara summit, Foreign Minister Maxime Prévot emphasized that “the Ankara summit must respond to a single challenge: demonstrating that NATO still speaks with one voice.” He added that “under American impetus, Europeans are now taking their defense responsibilities and emerging as a solid pillar.”

The NATO “Arctic Sentry” operation, launched on February 11, 2026, aims to strengthen NATO presence in the Arctic through intelligence, surveillance, and reconnaissance activities, as documented in the Wikipedia article on the operation. The operation supports exercises like Cold Response and Arctic Endurance and operates across air, maritime, land, cyber, and space domains.

What’s Next

Belgium’s defense transformation is just beginning. The country is transitioning from F-16 to F-35 fighter jets, with the Iceland mission expected to be the last for the F-16s. The Belgian military programming now covers land, air, and maritime dimensions, as well as cyber, space, and intelligence.

As the geopolitical landscape continues to evolve, Belgium faces the dual challenge of modernizing its military while addressing emerging threats from drones, cyberattacks, and hybrid warfare. The deployments to Greenland and Iceland signal a clear commitment to NATO solidarity, while investments in air defense and anti-drone capabilities demonstrate a determination to protect Belgian territory and infrastructure.

Liégeois noted that “NATO will remain a very unequal alliance, with the United States remaining by far the world’s first power,” and that “Europe does not have the ambition to balance American power.” But the message from Brussels is clear: Belgium is prepared to shoulder its share of the collective defense burden in an increasingly complex security environment.
