Cold Response 26 concludes: NATO strengthens northern flank readiness in Arctic conditions

As winter draws to a close in northern Europe, NATO’s Cold Response 26 exercises in northern Norway are reaching their final phase, providing a decisive test of alliance readiness in extreme Arctic conditions. Spanning several weeks and involving approximately 25,000 personnel from 14 NATO member states, the operation has integrated land, sea, and air components to validate interoperability, logistics, and operational readiness along the alliance’s northern flank.

Strategic significance of NATO’s northern flank

Northern Norway, encompassing the Barents Sea coast and Arctic approaches, remains one of Europe’s most strategically sensitive regions. Its maritime accessibility, port infrastructure, and proximity to potential adversary routes make it a critical point for NATO’s collective defense.

Cold Response serves multiple strategic purposes:

• Deterrence: demonstrating NATO’s capability to rapidly deploy forces and secure the northern flank.
• Readiness testing: exercising operational command structures, joint logistics, and rapid reaction in harsh environmental conditions.
• Operational familiarity: ensuring troops are proficient in Arctic warfare, including cold-weather mobility, amphibious operations, and combined arms coordination.

As Arctic temperatures remain low at the end of winter, Cold Response 26 has highlighted the persistent operational challenges posed by snow, ice, and limited visibility, which affect mobility, navigation, and communications.

Participating nations and force composition

Cold Response 26 brings together a broad coalition of NATO forces:

• Norway – hosting the exercise with corvettes KNM Skjold, KNM Glimt, and KNM Storm, logistics vessel KNM Maud, Arctic-capable marine units, and air assets.
• The Netherlands – contributing roughly 1,000 personnel, including Korps Mariniers, NH90 helicopters, and amphibious ships Zr. Ms. Johan de Witt (L801) and Zr. Ms. Van Amstel.
• United States, United Kingdom, France, Germany, Denmark, Sweden, Finland – providing combined land, naval, and air units, including specialized forces and logistical support.
• Smaller contingents from the Baltic states and Canada – focusing on specialized and support capabilities.

The exercise required meticulous coordination across domains, including maritime and air transport, at-sea replenishment, Arctic communications networks, and integrated command procedures under rapidly changing weather conditions.

Maritime operations: real-world readiness in action

Cold Response 26 has put NATO naval forces to the test, particularly corvettes of the Skjold-class, which conducted high-speed maneuvers, maritime interdiction, amphibious coordination, and even real-life rescue operations.

A notable example occurred in Andfjorden, where a 30-foot day cruiser carrying nine civilians lost steering during exercise operations. Despite being fully engaged in high-intensity training scenarios, KNM Skjold and KNM Glimt quickly diverted to the distressed vessel. The corvettes took control of the drifting cruiser and towed it to safety, later handing over the operation to the local rescue vessel Kaptein Buhre. No casualties were reported.

This incident highlights the dual readiness requirement for NATO maritime forces: the ability to execute complex training scenarios while simultaneously responding to real-world emergencies in Arctic conditions.

Operational lessons from Cold Response 26

As Cold Response 26 concludes, several key lessons emerge:

1. Interoperability is essential – integrating land, sea, and air forces from multiple NATO countries enables rapid, coordinated responses to dynamic operational scenarios.
2. Arctic logistics remain complex – fueling at sea, helicopter transport, and rapid deployment of ground units are vital capabilities tested under realistic conditions.
3. Dual-use readiness enhances resilience – forces must balance combat simulations with civilian safety operations, demonstrating flexibility and operational agility.
4. Strategic signaling reinforces deterrence – a visible, multinational presence in the Arctic sends a clear message about NATO’s commitment to northern European security.
5. Data-driven training improves future planning – lessons from terrain, weather, and interoperability challenges will inform upcoming Arctic Sentry exercises and NATO strategic planning for the High North.

End-of-winter observations

Conducting Cold Response 26 at the end of the Arctic winter provides particularly valuable insights. Snow and ice still pose navigational challenges, affecting mobility, helicopter lift capacity, and amphibious landings. This timing also simulates transitional conditions as spring approaches – a period in which operational readiness must remain high to address both natural and man-made contingencies.

For naval forces, maintaining continuous situational awareness and rapid response capacity during weather fluctuations is crucial. Similarly, for ground and air components, terrain familiarity, cold-weather operations, and interoperability under variable daylight conditions are key takeaways for future Arctic operations.

Implications for NATO’s Arctic strategy

Cold Response 26 forms part of the broader Arctic Sentry initiative, aimed at increasing NATO’s presence in the High North and enhancing readiness to respond to threats in the region. The exercise demonstrates that NATO’s northern flank is not only defended by strategic planning but also by practiced, interoperable forces capable of complex, multi-domain operations under extreme conditions.

The integration of real-world maritime rescue operations, large-scale amphibious maneuvers, and cross-domain coordination reinforces the importance of continuous, multinational training to preserve regional stability and deterrence.

As Cold Response 26 draws to a close, NATO forces consolidate lessons learned from one of the largest Arctic exercises in recent years. The final phase of operations underscores that:

• Northern Europe’s defense requires constant readiness in extreme climatic conditions.
• Interoperable multinational forces are capable of executing both combat simulations and emergency response simultaneously.
• Operational knowledge gained at the end of winter provides crucial insights for future Arctic deployments.

For NATO, the exercise is more than a routine winter drill – it is a demonstration of sustained commitment, deterrence, and operational excellence along the alliance’s northern flank, ensuring that Europe remains prepared to meet strategic challenges in the High North.
