The European Military Nuclear Industrial Base

France and the United Kingdom are the only European states that operate complete national nuclear weapons enterprises. Yet neither enterprise functions in isolation. Each depends on an extensive network of private-sector firms that design, build, integrate, maintain, secure, and enable strategic submarines, delivery systems, naval reactors, warhead-related infrastructure, and high-assurance facilities.

The central question addressed in this report is therefore not simply which companies are involved, but how the European private industrial base is structurally embedded within the military nuclear enterprise.

This analysis answers: How is the European private industrial base structurally embedded within the French and UK military nuclear enterprises? Which functional segments (strategic submarines, delivery systems, naval reactors, warhead-related infrastructure) depend on private firms? What evidence-first methodology and procurement entry points identify the companies actually involved? What does the company mapping reveal about structural dependencies and resilience of the enterprise?
