Macron Says France Will Increase Nuclear Warheads

France will increase its number of nuclear warheads for the first time in decades, President Emmanuel Macron announced Monday, marking a significant shift in the country’s nuclear deterrence policy.

Speaking at the L’Ile Longue military base in northwestern France, which hosts the nation’s ballistic missile submarines, Macron confirmed the expansion but did not specify how many additional warheads would be added to the current stockpile of fewer than 300.

“I have decided to increase the numbers of warheads of our arsenal,” Macron said.

The move represents the first increase in France’s nuclear arsenal since at least 1992 and comes amid heightened geopolitical tensions and growing debate over Europe’s strategic autonomy.

France’s nuclear deterrence and European security

Macron framed the decision as essential to preserving France’s long-standing doctrine of nuclear deterrence.

“My responsibility is to ensure that our deterrence maintains — and will maintain in the future — its assured destructive power,” he said.

France is currently the only nuclear power within the European Union, positioning its arsenal as a cornerstone of European security architecture. The announcement follows recurring tensions between European leaders and US President Donald Trump, which have raised questions about Washington’s commitment to defending Europe under the longstanding “nuclear umbrella” policy.

That policy has historically guaranteed that NATO allies would be protected by American nuclear forces in the event of a major threat.

Coordination with European partners

Macron reiterated that while France is open to deeper dialogue with European partners regarding nuclear deterrence, ultimate authority remains with Paris.

“If we had to use our arsenal, no state, however powerful, could shield itself from it, and no state, however vast, would recover from it,” he said.

Several European nations have engaged in discussions about closer coordination. Earlier this month, German Chancellor Friedrich Merz revealed he had held “initial talks” with Macron and publicly floated the possibility of German Air Force aircraft carrying French nuclear weapons.

In July, France and the United Kingdom adopted a joint declaration allowing their independent nuclear forces to be “coordinated.” The UK — the only other European country with a nuclear deterrent — remains a key NATO ally despite no longer being a member of the European Union.

Macron has consistently maintained that any decision to deploy France’s nuclear weapons would rest solely with the French president, underscoring national sovereignty even as Europe explores deeper strategic cooperation.

The expansion signals a new phase in France’s defense policy, as European leaders confront evolving security threats and reassess the continent’s long-term reliance on US military guarantees.
