UK helicopters train in Arctic as Operation Clockwork runs

UK military helicopters have deployed to northern Norway as Commando Helicopter Force begins its annual Arctic training deployment under Operation Clockwork.

Aircraft from Commando Helicopter Force and 18 Squadron Royal Air Force are operating from Royal Norwegian Air Force Base Bardufoss inside the Arctic Circle, where crews are training in extreme cold weather conditions ahead of major NATO activity later this year.

The deployment brings together Merlin, Wildcat and Chinook helicopters, with aircrews, engineers and ground personnel working to maintain operational effectiveness in snow, ice and sub zero temperatures. During recent training serials, Chinook helicopters from 18 Squadron were fitted with specialist snow skis while conducting underslung load lifts. The skis attach to the aircraft’s wheels to prevent them from sinking into deep snow, allowing safe landings and operations in Arctic and mountainous environments by distributing the helicopter’s weight.

Royal Marine Viking BVS10 armoured vehicles were used to move personnel and equipment during the training, supporting helicopter operations across snow covered terrain. Alongside flying activity, personnel are undertaking Arctic survival training designed to prepare crews to live and operate in remote conditions. This includes learning to ski, navigate across wilderness terrain, build shelters and forage for food if required.

The flying phase focuses on operating across Norway’s fjords and mountains, placing sustained demands on pilots, observers and engineers as aircraft performance and maintenance procedures are tested in prolonged cold weather. Operation Clockwork is a long running UK commitment to Arctic and High North operations and forms a key part of Britain’s contribution to NATO’s northern posture. The deployment will culminate in preparation for Exercise Cold Response 2026, the largest military exercise scheduled in Norway this year, which is intended to demonstrate allied unity and NATO’s ability to deter threats in the High North.
