Defence Data Architecture

Europe’s defence transformation is increasingly becoming a data architecture problem. Modern military capability depends not only on platforms, sensors and weapons systems, but on the ability to govern, share, secure and exploit data across national borders, industrial supply chains and allied command structures.

The emerging European Defence Data Space should therefore be understood as more than a cloud or digitalisation initiative: it is a strategic infrastructure layer for AI-enabled defence, software-defined systems, digital twins, predictive maintenance, multinational readiness and European industrial sovereignty.

This analysis answers: Why is Europe's defence transformation increasingly a data architecture problem beyond platforms, sensors and weapons? How should the European Defence Data Space be understood as a strategic infrastructure layer rather than a cloud or digitalisation initiative? What institutional, technical and governance architecture underpins governing, sharing and securing data across borders and supply chains? What industrial, financial and legal implications follow for AI-enabled, software-defined defence?
