Why is NATO increasing its presence in the Arctic?
NATO will increase its presence in the Arctic. The alliance is threatening the West by citing Russia as the greatest threat. In response, NATO is preparing to announce a new mission called "Arctic Sentry".
Operation Arctic Watch
On February 11, NATO Secretary General Mark Rutte issued a strong message from headquarters in Brussels: "The Arctic and the Arctic region are more important than ever to our collective security. Given Russia's increased military activity and China's growing interest in the Arctic, stronger action is absolutely essential."
This new mission is called "Arctic Frontier." Essentially, it's designed similarly to the deterrence operations NATO has been conducting in the Baltic Sea and Eastern Europe. While not a drastic change from what the Nordic allies have been doing for years to defend themselves against Russia, this mission marks a turning point in tactical thinking and unified coordination under a common banner.
The launch of the "Arctic Frontier" comes amidst deep rifts within the alliance. Last month, President Donald Trump's demand for the U.S. to take control of Greenland – seen as a forward missile defense line – threatened to split NATO. However, this new mission appears to be the alliance's unified response to geopolitical challenges, transcending internal disagreements.
One of the most significant changes to the "Arctic Frontier" is the increased troop presence in the area known as the "Northern Tip"—a territory within the Arctic Circle encompassing parts of Norway, Sweden, and Finland. According to Minna Alander, a defense and Arctic expert at the Stockholm Centre for Eastern European Studies, these three countries are likely to play a leading role in the new initiative, thanks to their extensive experience operating in this harsh environment.
The alliance plans to increase naval patrols in the Norwegian Sea and the waters between Greenland, Iceland, and the United Kingdom – the strategically important GIUK region. This area could become a testing ground for the latest reconnaissance drones, as NATO seeks to determine if they can withstand the harsh Arctic climate.
"The alliance's priorities have shifted to the Arctic region, and NATO is responding to that challenge," Matthew Whitaker, the U.S. ambassador to the alliance, told reporters on Tuesday.
Not just the Nordic countries, other NATO powers are also shifting their focus. British Defence Secretary John Healey announced on February 11th that the UK would double its troop deployment to the Norwegian Arctic, bringing the total to 2,000 within the next three years. London will also join a ground force of at least 4,000 soldiers under Swedish command, stationed in northern Finland. France, Iceland, and Italy are already present there. This force is expected to be fully combat-ready in the coming months.
Threats from the ocean depths
The main impetus for NATO's decisive action comes from the "telling" numbers. According to data from the Center for Strategic and International Studies (CSIS), since the beginning of 2025 alone, Russia has conducted at least 33 military exercises in the Arctic.
However, the West's greatest fear lies not on the ice, but beneath the ocean's surface. NATO officials are particularly concerned about the scenario in which Russia could deploy nuclear submarines through the Norwegian Sea to enter the vast expanse of the Atlantic Ocean undetected.
Minna Alander commented: "If that happens, the game is over. Finding a submarine lurking in the vast Atlantic Ocean is a nearly impossible task."
Western officials have also warned of a subtle "cat and mouse" game involving Russia's use of "shadow fleets" to transport sanctioned oil and its alleged sabotage of critical infrastructure, including energy pipelines and undersea cables.
With "Arctic Frontier," NATO is not simply conducting exercises. It's a powerful statement that the frigid North will no longer be the "backyard" of any major power, and the world's largest military alliance is ready to defend every inch of its ice against the cold winds from the East.
NATO, which has long considered Arctic exercises a routine activity, will deploy approximately 25,000 military personnel and civilians to participate in drills starting in mid-March. In addition, there will be two similar deterrence missions in the Baltic region and Eastern Europe.
