UK Military Participates in Key Trilateral Arctic Exercise to Strengthen Strategic Presence in the High North

The Royal Marine Commandos and personnel from the Royal Air Force have joined forces with Norwegian and American allies on the remote Arctic island of Jan Mayen as part of Operation Atlantic City. This initiative aimed to evaluate NATO’s capabilities in navigating and operating within the severe conditions typical of the Arctic, where meticulous planning is essential due to the demanding weather and terrain.

Demonstrating NATO’s Enhanced Capabilities

The deployment to Jan Mayen, which took place from 26 August to 4 September 2026, involved members of LXX Squadron from the Royal Air Force alongside detachments from the UK Commando Force. This trilateral operation was a vital component of Arctic Sentry, NATO’s enhanced vigilance activity in the High North.

Jan Mayen, located approximately 620 miles from mainland Norway, holds significant geostrategic importance. It lies north of the crucial Greenland-Iceland-UK gap, a waterway essential for the defence of Northern Europe and the broader Euro-Atlantic region.

This operation facilitated collaboration between UK forces and the Royal Norwegian Navy, the Norwegian Home Guard, and units from the US Marine Corps. By integrating various sensor and communication systems, NATO enhanced its preparedness for potential threats in the region.

Commitment to Collective Security

The UK’s involvement in this operation underscores its commitment to NATO’s collective security and its readiness to tackle the distinct challenges presented by Arctic operations. Defence Secretary Wes Streeting commented on the significance of the High North for the security of the UK and its NATO allies, stating that the operation exemplifies the strength of the partnership with Norway and the United States.

Streeting emphasised that this deployment serves as a clear indication of the UK’s ongoing commitment to NATO security and the defence of shared interests in the High North.

Maximising Resources Across the Theatre

Operation Atlantic City ran in parallel with naval exercises during Operation Northern Viking 26, allowing the combined forces to leverage overlapping maritime and sensor resources across the European theatre while simultaneously supporting NATO’s broader Arctic Sentry initiatives.

This exercise builds on similar training conducted by Allied forces around Jan Mayen last year, drawing upon the island’s historical significance and strategic location.

Training in Challenging Conditions

Training in the Arctic equips UK forces with invaluable experience in maritime operations, surveillance, movement, survival, and joint operations, all under some of the most challenging weather conditions in the world. Forces operating in the High North must be adept at overcoming obstacles related to distance, extreme weather, limited infrastructure, and rapidly changing environments.
