• NATO is poised to launch the Arctic Sentry mission, an enhanced vigilance activity to strengthen surveillance in the Arctic and around Greenland, possibly as early as this week.
  • The mission, modeled after the successful Baltic Sentry operation, will employ naval drones, warships, submarines, and aircraft to monitor the region amid rising Russian and Chinese influence.
  • Planning accelerated following President Donald Trump's concerns about NATO's vulnerability in the Arctic, with discussions expected at the NATO Defence Ministers meeting on February 12, 2026.

NATO is actively planning the Arctic Sentry mission, with sources indicating a launch could occur in the coming days, possibly later this week. This enhanced vigilance activity aims to bolster the alliance's military presence and surveillance capabilities in the Arctic region and around Greenland, according to people familiar with the matter. Military planning is underway, with discussions slated for NATO's Defence Ministers meeting scheduled for February 12, 2026.

Arctic Sentry is modeled after Baltic Sentry, NATO's successful operation launched in 2025 to protect critical infrastructure in the Baltic Sea by monitoring undersea activities and tracking suspicious vessels. The Arctic mission will employ similar surveillance capabilities, including naval drones, warships, submarines, and aircraft to monitor the region. Its primary focus is Greenland, the autonomous Danish territory that has become a strategic priority for NATO following concerns about Russian and Chinese influence in the Arctic. Arctic Sentry aims to demonstrate NATO's commitment to Arctic security and strengthen the alliance's posture in the High North.

The mission planning accelerated following President Donald Trump's assertions that NATO is vulnerable to Russian and Chinese influence in the Arctic—concerns he cited as justification for U.S. acquisition of Greenland. While Trump's initial demands for control of Greenland created diplomatic tension with Denmark and NATO allies, tensions eased after Trump met with NATO Secretary-General Mark Rutte at the World Economic Forum in Davos in late January. Trump subsequently announced he would not impose additional tariffs on eight European countries that deployed military delegations to Greenland.

A group of European nations, led by the United Kingdom and Germany, has discussed plans to expand their military presence on Greenland as a signal to Trump of Europe's Arctic security commitment. German Defense Minister Boris Pistorius noted in late January that Arctic Sentry discussions were "progressing well." British Defense Secretary John Healey characterized Arctic Sentry as a way NATO can "demonstrate to President Trump that we're already stepping up on Greenland's security."

According to NATO's Supreme Headquarters Allied Powers Europe (SHAPE) spokesperson Martin L. O'Donnell, planning work is underway but no specific launch date has been announced. The activity is expected to be discussed at NATO's Defence Ministers meeting on February 12, 2026. Efforts to finalize the mission have hit a snag in recent days, with sources citing logistical challenges in coordinating multinational assets, but insiders say a deal is imminent to avoid delays that could undermine NATO's credibility.

The Arctic has become increasingly critical to NATO due to several factors: the region serves as a connector between Europe and North America; Greenland hosts Pituffik Space Base, where the U.S. operates missile early-warning radars; the shortest ballistic trajectory between Russian launch sites and North America runs through the Arctic; and climate change is opening new maritime routes, making Arctic control strategically important. Russia and China are increasingly conducting joint patrols and operations in the Arctic, representing a "most concerning change" in the security situation, according to military analysts.

Denmark and Greenland have initiated talks with the United States regarding renegotiation of a 1951 treaty governing American troop deployments on the island. Danish Prime Minister Mette Frederiksen has indicated that NATO countries support establishing a "permanent presence" in the Arctic as part of enhanced security efforts. NATO also launched Eastern Sentry in September 2025, a similar multi-domain vigilance activity along the alliance's eastern flank, which Arctic Sentry will build upon in terms of experience and innovative technologies.

Attempts to reach NATO officials for further comment were unsuccessful as of press time, but sources close to the negotiations suggest that without a finalized agreement this week, the mission could face postponement, potentially straining alliance cohesion ahead of the February meeting. Market watchers note that defense stocks have seen slight upticks in anticipation of increased military spending, though broader implications for global markets remain muted pending official confirmation.
