BRUSSELS: NATO has launched a new mission, Arctic Sentry, aimed at strengthening the alliance’s military presence in the Arctic amid growing strategic competition and recent tensions sparked by US interest in Greenland. The initiative, announced on Wednesday, will coordinate allied activities in the region, including exercises such as Denmark’s Arctic Endurance, and assess gaps in capabilities that need addressing.

NATO Secretary General Mark Rutte said the mission will unify efforts across member states as Russia and China increase their Arctic engagement and new sea lanes open due to melting ice. “We will not only be able to leverage what we are doing much more effectively, but also assess which gaps there are, which we have to fill,” Rutte said.

German Defence Minister Boris Pistorius confirmed that Germany will contribute four Eurofighters and air-to-air refueling capabilities during the first stage of Arctic Sentry. British Defence Minister John Healey also highlighted the UK’s role, noting that British forces, alongside the UK-led Joint Expeditionary Force, plan large-scale activity across Iceland, the Danish Straits, and Norway later this year.
The mission’s planning accelerated following discussions in Davos between US President Donald Trump and Rutte during the so-called Greenland crisis, when Trump proposed acquiring the Danish territory for strategic reasons. While Trump later ruled out forceful acquisition, NATO agreed to take a more active role in Arctic security.
Arctic Sentry, classified as an “enhanced vigilance activity,” will be led by NATO’s Joint Force Command in Norfolk, Virginia. US Air Force General Alexus G. Grynkewich, NATO’s Supreme Allied Commander Europe, said the operation reflects the alliance’s commitment to safeguard members and maintain stability in one of the world’s most strategically important and environmentally challenging regions.

Denmark will contribute significantly to the mission, coordinating with Greenland and the Faroe Islands, while further details of troop deployments and assets are to be finalized with NATO allies. The initiative underscores NATO’s focus on ensuring stability in the High North amid intensifying geopolitical interest.
