The countries of Northern Europe have long shared close political and cultural relationships, but their approaches to defence have often evolved independently. In recent years, however, Denmark, Finland, Iceland, Norway and Sweden have established a new level of collaboration on military issues through the Nordic Defence Cooperation, better known as NORDEFCO.
A flexible framework for collective benefit
NORDEFCO came into being on 4 November 2009, replacing earlier frameworks that addressed armaments, peace support and supportive defence structures. Its foundational idea is that the participating nations can achieve more together than apart, especially through cost sharing and developing common solutions. Each member decides for itself which aspects of NORDEFCO’s work it participates in, so bilateral projects frequently operate alongside efforts involving all five nations.
The cooperation model is designed to respect political realities. Each Nordic country has different international obligations and defence alliances, which has sometimes complicated full integration. Nevertheless, the five members regularly identify new ways to combine their strengths. Working alongside other nations outside the group is also possible when it would bring clear advantages.
Organisation and achievements
Leadership within NORDEFCO rotates among the member states, but ultimate responsibility lies with the defence ministers, who meet twice annually. Beneath them, committees of senior defence officials and military officers coordinate projects across areas such as training, personnel development, operations and strategic planning. Specialist working groups focus on interoperability, equipment and logistics, sharing procurement plans to avoid duplication and save money. These joint efforts have already allowed the group to achieve collective savings exceeding €60 million.
One notable result of this collaboration is the development of the Nordic Combat Uniform. Beginning with a comprehensive review of the clothing needs for all climates in the region, the countries worked together to commission a common design, chosen after extensive testing. Although each country retains its own camouflage patterns, the core system, covering all apparel from base layers to outerwear, has been unified since the first orders were placed in 2022.
While NORDEFCO is not a mutual defence alliance in the traditional sense, the lines have begun to shift. In recent years, Denmark, Norway and Sweden created new structures to make it easier for their forces to coordinate during times of crisis or conflict, particularly in southern areas of the Nordic region. Finland, Norway and Sweden have taken similar steps in the north. Members have also agreed to grant each other access to airspace and military installations, further improving their ability to work together if needed.
The changing security environment in Europe influenced these developments. When Finland and Sweden sought NATO membership in 2022, their Nordic neighbours, Denmark, Iceland and Norway, publicly committed to using all means available to assist if either country came under attack during the application period.
