NATO Launches Arctic Sentry Security Effort

NATO on Feb. 11, 2026 launched Arctic Sentry, a coordinated security initiative to consolidate Allied exercises and operations in the Arctic and High North, Secretary General Mark Rutte said. The initiative initially integrates Denmark's Arctic Endurance and Norway's Cold Response, and Allied Command Operations will use Arctic Sentry to create an overarching operational approach amid increased Russian activity and growing Chinese interest.
