French President Emmanuel Macron has announced a significant shift in France’s defense strategy, proposing the potential deployment of nuclear-capable aircraft in the United Kingdom. This initiative is part of what he refers to as an “advanced deterrence” approach aimed at reinforcing France’s nuclear capabilities amid growing global threats.
During a speech at Île Longue, France’s nuclear facility in Brittany, Macron emphasized the need for a robust nuclear deterrent. “We must strengthen our nuclear deterrent in the face of multiple threats, and we must consider our deterrence strategy deep within the European continent, with full respect for our sovereignty,” he stated. This announcement follows the Northwood Declaration signed by France and the UK in July, which underscored the independent yet coordinated nature of their nuclear forces.
Under the new plan, France will allow the temporary positioning of its strategic air forces, including nuclear-armed jets, in participating European nations. The countries involved in this scheme include Britain, Germany, Poland, the Netherlands, Belgium, Greece, Sweden, and Denmark. Notably, Germany and Poland have expressed interest in relying on France’s nuclear umbrella, suggesting that the aircraft are more likely to be stationed in those countries rather than in the UK.
Macron also revealed that France would increase its nuclear warhead stockpile for the first time since the 1990s. Currently, the French arsenal is estimated to be just under 300 warheads, while the UK’s stockpile stands at approximately 225 as of 2025. He described the strategic distribution of these forces across Europe as akin to “an archipelago of force,” designed to complicate adversaries’ calculations and enhance strategic depth.
The French president reiterated the importance of collaboration among European nations in nuclear deterrence. During his state visit to the UK in July, Macron and UK Labour leader Sir Keir Starmer committed to deeper cooperation in this area. Alongside nuclear coordination, Macron mentioned that Germany, the UK, and France would collaborate on developing long-range missile projects under the European long-range strike approach, known as ELSA. This trilateral initiative aims to create new conventional strike systems in response to Russia’s expanding missile arsenal, addressing the erosion of global nuclear governance.
Macron’s announcements mark a pivotal moment in European defense strategy, highlighting the need for solidarity among European nations in the face of evolving security challenges. The proposed nuclear deployments signal a broader commitment to collective security and deterrence in a rapidly changing geopolitical landscape.
