Regulatory Harmonisation for Pan-European Defense Manufacturing

European defence planners are driving an unprecedented push to harmonise regulations and standards across EU Member States’ defence sectors. Behind this effort lie urgent strategic motivations. Russia’s war against Ukraine starkly exposed the inefficiencies of a fragmented European defence market, where incompatible systems and disjointed procurement hindered rapid response.

EU leaders have concluded that a patchwork of national rules and procedures not only wastes resources but also undermines Europe’s strategic autonomy – its ability to sustain a credible defence industry and supply its own military needs.

This analysis answers: What strategic motivations drive the EU push to harmonise defence regulations and standards across Member States? How did fragmentation and incompatible systems hinder rapid response and undermine European strategic autonomy? What mechanisms would harmonisation require, and which actors and procedures does it affect? What are the compliance and industrial implications of pan-European standardisation for defence manufacturing?
