New report: The cross-Nordic defence industry is taking shape

Nordic defence cooperation is beginning to translate into concrete capability development and procurement decisions, as regional alignment deepens and uncertainty over United States security guarantees grows.

That is the conclusion of a new report from the Danish Institute for International Studies (DIIS). It finds that the Nordic countries are now more closely aligned on security policy than at any point in recent history following Finland and Sweden’s accession to NATO.

The shift matters because cooperation is moving beyond interoperability towards interchangeability, the ability to share equipment, maintenance and training across borders. 

According to the report, this alignment creates a window for deeper cooperation as all five countries increase defence spending and prepare major procurement programmes in parallel.

In practical terms, this opens the door to more joint acquisition of platforms, shared maintenance structures and cross-border training. It also raises the possibility of borrowing and lending equipment between countries in a crisis, increasing operational flexibility.

Already taking place

Recent events, including Nordic support for Denmark during tensions over Greenland, are highlighted as examples of political alignment beginning to translate into operational cooperation.

For the defence industry, the shift could carry tangible consequences. 

A move towards standardisation and shared systems would favour scalable, cross-border solutions over highly customised national requirements. Policymakers are increasingly prioritising speed and volume in procurement rather than country-specific optimisation.

However, the report also highlights persistent challenges. 

Coordination across governments remains complex, and differences in geography and operational priorities are likely to limit the scope for full integration. National industrial interests are also expected to constrain major programmes.

While Nordic cooperation is not seen as a replacement for NATO, it is emerging as a pragmatic hedge in a more uncertain strategic environment.

The direction of travel is clear: Nordic defence cooperation is no longer primarily political, it is beginning to materialise in capabilities, procurement decisions and operational planning.
