French President Emmanuel Macron today unveiled a substantial redefinition of France’s nuclear deterrence doctrine, signaling an increase in the total number of atomic weapons controlled by Paris. This move, justified by the current „ambient animosity,” is deemed „necessary for a strengthening of our defense model,” stated the Élysée leader.
A New Era for French Nuclear Deterrence
In a 45-minute speech delivered to armed forces personnel and officials, at a dry dock alongside a nuclear ballistic missile submarine (SNLE), Macron emphasized the „indispensability” of modernizing the French arsenal. Although he did not provide precise figures, he noted that France „will no longer communicate their numbers.” The speech, described as an expression of „assumed might in the service of peace,” highlighted the need to guarantee „the credibility of our nuclear deterrence,” considering that „we cannot be satisfied with our current trajectory.” Macron reaffirmed that French doctrine is not based on a graduated nuclear response, but is „strategic and exclusively strategic.”
Extending the French Nuclear Umbrella: A European Discussion
In addition to consolidating the national arsenal, Macron revealed that France is engaged in active discussions with several European nations, including Germany, the United Kingdom, Poland, the Netherlands, Belgium, Greece, Sweden, and Denmark, for an „advanced deterrence” initiative related to the French nuclear umbrella. The President clarified that this does not imply the deployment of French nuclear weapons on foreign soil.
Modernized Armaments and Unprecedented Capabilities
Acknowledging that French nuclear power „is not achieved without effort,” Macron nevertheless stressed that investments are paying off. In the coming months, the new M51.3 missiles will be operationalized on the French Navy’s SNLE submarines, equipped with a „new optimized oceanic nuclear warhead designed to penetrate all defenses.” A fifth SNLE submarine, named „Invincible,” will be built and ready for launch by 2036. The French leader also announced the launch of a „very ambitious” program for a hypersonic and maneuverable strategic missile, which will equip combat aircraft and the future French aircraft carrier in the next decade.
An Unequivocal Warning to Adversaries
In a direct message to potential enemies, Macron did not hesitate to warn: „If we have to use our nuclear arsenal, no state, however powerful it may be, will be able to avoid the consequences. None, however vast it may be, would recover.” He underscored the devastating force, recalling that „a single one of our submarines carries more strike power than all the bombs that fell in Europe during World War II. It’s almost 1,000 times greater than the first nuclear bombs.” The President acknowledged that „our adversaries have changed, our partners too, and the world is getting tougher, as the last few hours have shown,” alluding to the war in Iran.
„Forward Deterrence”: Macron’s Concept for European Defense
Macron advocated for „strengthening our nuclear deterrence against the combination of threats” and for rethinking strategic deterrence „within the depths of the European continent, with full respect for our sovereignty,” through the progressive implementation of what he called „forward deterrence.” This concept, he explained, is a „progressive procedure” that allows partner nations „to participate in our deterrence exercises.” It could involve „warnings, including beyond our borders, or allied forces taking a conventional part in our nuclear activities.” It also provides for „the deployment of our strategic air forces to disseminate in depth across the European continent […] like an archipelago of forces which will complicate the calculations of our adversaries and will give this forward deterrence a lot of value for us.”
Key Reactions and Partnerships: From Berlin to Warsaw
The French President stated that Germany, the United Kingdom, Poland, the Netherlands, Belgium, Greece, Sweden, and Denmark „have agreed” to take part in this initiative, emphasizing that „Germany will be a key partner.” Shortly after the speech, German Chancellor Friedrich Merz confirmed on Twitter the establishment of a Franco-German nuclear steering group, announcing concrete steps before the end of the year, including conventional German participation in French nuclear exercises. Polish Prime Minister Donald Tusk posted on X that Poland „is in talks with France and a group of closest European allies” on the advanced nuclear deterrence program, stating that „we are arming up together with our friends so that our enemies will never dare to attack us.” Swedish Prime Minister Ulf Kristersson had previously revealed discussions with France. Macron also mentioned the tightening of ties with the United Kingdom in July 2025, a nuclear power with whom France has recognized since 1995 that the vital interests of one affect those of the other.
France’s Role: The Final Decision Remains Sovereign
Macron clarified that, despite cooperation, „there will be no sharing in the ultimate decision [to launch a nuclear strike], nor in its planning or implementation,” responsibilities that lie „exclusively with the President of the Republic.” He specified that the first steps in this forward deterrence will include joint exercises and visits to strategic sites. He also indicated that discussions are ongoing with a number of other, unspecified European nations interested in joining the program to strengthen Europe’s defense in three key areas: early warning of ballistic and hypersonic threats (the Franco-German JEWEL initiative), the Franco-Italian SAMP/T NG Mamba air defense system, and the ELSA (European Long-range Strike Approach) program for advancing long-range strike and defense capabilities.
In conclusion, Macron declared that he wants „Europeans to retake control of their own destiny,” signaling a major strategic reorientation for the continent’s security.
