This article studies the Federated Advanced Cyber Physical Test range (FACT), a new initiative launched by the European Defence Fund (EDF) in December 2023 to develop a next-generation European cyber test-bed capability. The dependence of military and civil-urban infrastructures on digital and IoT systems underscores the need for and importance of a European cyber range to test military equipment on its cyber resilience. The article addresses the cyber vulnerability of these infrastructures under the current context of hybrid warfare and foreign cyber potential. The FACT case study underlines how this initiative embodies a capability that has yet to be achieved in the current EU framework by creating a shared cyber range test-bed. The analysis of pertinent EU-based NATO-owned cyber infrastructure also emphasises the existing future potential for appropriation and integration into a new European cyber architecture.  Finally, the article stresses how FACT shows the potential and political willingness to change European cyber-resilience and interoperability in the long-term.
