Europe's Military Dependency Is in the Enablers, Not the Budgets

As of mid-2025, exo-atmospheric mid-course missile interception in Europe was provided solely by the United States. Not mostly. Solely. If a ballistic missile has to be stopped above the atmosphere over European territory, an American system does it or nothing does.

Europe has spent three years talking about strategic autonomy. On the capabilities that decide whether a continent can defend itself without permission, it has moved barely at all.

Four Numbers That Define the Dependency

The dependency is concentrated in enablers rather than in soldiers or tanks. European NATO members operate 49 military satellites against 246 American ones. On crewed intelligence and surveillance aircraft the ratio is at least 80 US to 36 European. Roughly half of Europe's active fighter fleet is American-made.

The Gaps Are in the Plumbing, Not the Platforms

European governments like announcing equipment. Enablers are harder to photograph and harder to buy. Europe lacks a space-based missile early warning system entirely. France and Germany are building one, Joint Early Warning for a European Lookout, with an initial capability targeted for the early 2030s.

The IISS assessment is blunt about the timeline. Even under a burden-sharing model, Europe could not field a sovereign space-based missile early-warning architecture, match the scale of American intelligence and surveillance coverage, or replicate US space situational awareness within a decade. The hardest gaps to close are precisely the ones where dependency is deepest, because those capabilities are capital intensive, globally distributed and time sensitive.

A continent that cannot detect a missile launch on its own satellites, cannot intercept it above the atmosphere, and cannot see its own periphery without American aircraft is not defending itself. It is being defended.

Money Is Arriving. Coordination Is Not.

The funding picture has changed fast. European defence spending in 2025 ran more than 50% above its earlier level. Germany announced EUR 35 billion for military space capabilities by 2030. France added EUR 4.2 billion for military space between 2026 and 2030, with sentinel satellites planned from 2027. The EU has SAFE and the wider rearmament programme behind it.

The problem is that these are national answers to a continental problem. The IISS conclusion is that the investments are not structured around a coherent strategy to close the most consequential gaps within a decade. National priorities and mixed signalling at European level risk duplication in ballistic and hypersonic defence while the early-warning layer stays empty.

The Nuclear Question Is Already Open

In March 2026, Macron announced the first increase in the French warhead stockpile since 1992 and a doctrine he called forward deterrence, built around strategic partnership with seven European states, participation in nuclear exercises and the possible temporary deployment of French nuclear-armed aircraft to allied territory. The UK and France deepened their own nuclear cooperation in July 2025.

This is real movement, and it is also carefully limited. French command and control remains sovereign, and Paris has been explicit that forward deterrence complements rather than replaces the American nuclear guarantee. Macron's implicit bargain is that partners take on early warning, air and missile defence and conventional deep strike while France handles the nuclear layer.

That bargain only works if Europe delivers its half. Which returns to the same four numbers.

What a European Defence Pillar Requires

The goal is not a European army, which nobody will agree to, or leaving NATO, which would be self-defeating. It is a European pillar inside the alliance capable of operating without American enablers if it has to.

The last row is the one that gets skipped. Capability without a decision-making process is inert. A continent that needs unanimity among 27 governments to act cannot use the forces it is now paying for.

Conclusion

None of this is a case against the alliance. American capability underwrote European security for seventy years and still does, and the fastest route to a capable Europe runs through NATO rather than around it. The 2026 US defence authorisation mandates a minimum troop presence of 76,000 in Europe, which buys time.

Time is the one thing Europe keeps spending without noticing. A dependency that takes a decade to unwind has to be started a decade before it is needed. On early warning and interception, Europe is already late.
