U.S. Marines test expeditionary advanced based operations concepts in the Arctic alongside NATO Ally forces from the U.K. Royal Air Force and the Norwegian armed forces, Sept. 1 - 3, 2025. The Norwegian-led arctic operation was a first-of-its-kind mission to conduct rapid insertion of military assets to remote and austere location. The operation focused on NATO sea denial and maritime domain awareness capabilities and helps set conditions to quickly respond and defeat any crisis or threat to NATO allies.
