Danish F-35 fighter jets were deployed alongside U.S. and Canadian forces across the Arctic and the North Atlantic as part of Operation Noble Defender, an annual air defense exercise conducted by the North American Aerospace Defense Command (NORAD).

The deployment brought together aircraft and personnel from Denmark, the United States, Canada, and France to conduct air operations in high-latitude environments known for extreme weather, long distances, and limited infrastructure.

Over two weeks, Royal Danish Air Force F-35A fighters were deployed forward to Keflavík Air Base in Iceland, from which they conducted air operations and surveillance over Iceland and the southeastern approaches to Greenland.

The Danish Armed Forces said the mission made a central contribution to the operation and highlighted Denmark’s growing role in Arctic air defense following the introduction of the F-35 into frontline service.

Forward Operations from Iceland and Greenland

From Keflavik, Danish F-35s conducted surveillance and air policing sorties under NORAD command and control, operating alongside U.S. and Canadian aircraft in the Arctic and North Atlantic. The location enabled rapid access to northern airspace while placing significant logistical and environmental demands on crews and equipment.

At the same time, Denmark deployed a Challenger aircraft to Kangerlussuaq in western Greenland to provide search and rescue coverage.

The aircraft ensured immediate rescue readiness during U.S. and Canadian air operations launched from Pituffik Space Base in northern Greenland, underscoring the risks associated with flying in Arctic conditions where response distances are long and survival times can be limited.

One Danish Challenger transport aircraft also operated from Iceland, supporting personnel movement and logistics during the deployment.

Allied Support and Aerial Refueling

Danish fighter operations were supported by a French Air and Space Force A330 MRTT aerial refueling aircraft during longer sorties. Tanker support allowed the F-35s to remain on station for extended periods despite the vast distances involved in Arctic operations.

The multinational setup provided a test of coordination between allied air forces and highlighted the importance of aerial refueling and logistical support in sustaining high-latitude missions.

Operation Noble Defender is a recurring NORAD activity focused on demonstrating and maintaining the ability to employ air forces under difficult climatic conditions, such as those in the Arctic.

NORAD, a binational U.S.-Canadian command, is responsible for monitoring airspace and protecting the North American continent against potential threats.

Fifth-Generation Jets in Extreme Conditions

The deployment also marked one of the most demanding operational uses of Danish F-35s to date. Danish pilots and ground crews operated in severe cold, limited infrastructure, and long-range sortie profiles that reflected real-world Arctic contingencies.

The operation provided a test of the aircraft’s sensors, propulsion systems, and sustainment capabilities in sub-zero temperatures and turbulent North Atlantic weather.

Danish F-35s operated alongside U.S. and Canadian fighters, validating data sharing and situational awareness provided by the aircraft’s advanced radar, electro-optical sensors, and secure communications systems.

The missions highlighted the ability of fifth-generation aircraft to maintain persistent surveillance and air defense coverage in remote environments.

The Royal Danish Air Force is in the process of introducing the F-35A into full operational service as part of a planned fleet of 27 aircraft.

More than a dozen jets have already been delivered and declared operational, with increasing focus on expeditionary and Arctic missions. The latest deployment marked a shift from national air policing tasks toward sustained multinational operations under NORAD command.

Experience in Multinational Arctic Operations

Operation Noble Defender provided experience in operating advanced fighter aircraft in demanding Arctic environments while strengthening cooperation between Denmark and its allies.

Danish defense officials said the mission offered valuable training in coordination, logistics, and operational planning across multiple countries and platforms.

Denmark has previously participated in the operation with search and rescue capabilities, but this year’s deployment placed the F-35 at the center of its contribution.

The mission also demonstrated how allied air forces can integrate fifth-generation fighters, aerial refueling assets, and support aircraft to maintain a sustained presence across the High North.

As strategic attention increasingly focuses on the Arctic and North Atlantic, the operation highlighted the role of allied cooperation in maintaining air security and readiness in the region.

Lessons from the deployment are expected to inform future operations and contribute to the continued development of Arctic air defense capabilities among NORAD partners and NATO allies.
