European defence capability development is currently shaped by a structural tension between urgency and inertia. On one side, the return of high-intensity warfare on the European continent has generated immediate demand for rapid capability enhancement, industrial scaling, and accelerated deployment of new technologies.

On the other, the material reality of European force structures remains anchored in long-lived legacy platforms, complex certification regimes, and highly integrated system architectures that cannot be replaced at the speed required by the strategic environment.

This analysis answers: How does the tension between urgency and inertia shape European capability development anchored in long-lived legacy platforms? What is the technical integration logic for inserting startup technologies onto legacy systems via modularity and open architectures? How do prime contractors as system integrators, and acquisition or exclusive-supplier status, function both as success paths and as risks? What are the investor, policy and industrial-readiness implications of this thesis?
