- France test-fired its new M51.3 nuclear-capable ballistic missile for the first time on October 6, 2026, launching it from the nuclear-powered submarine Le Vigilant off Brittany without a warhead aboard.
- The missile impacted "in the North Atlantic, hundreds of kilometres from any coastline," and the defence ministry confirmed the test was carried out "in strict compliance with France's international commitments."
- President Macron personally witnessed the firing from a French warship, according to an official who spoke to AFP.
- The French defence ministry said the test "once again demonstrates the excellence of the high-tech solutions employed by French industry in the field of nuclear deterrence."
- The launch came as Macron warned of a shift in "Russian aggression and threats" against European nations, citing "hybrid" attacks blamed on Moscow, and vowed in mid-September that such actions would "not go unanswered."
- Macron also proposed this year that they participate in France's "advanced" nuclear deterrence framework — France remains the European Union's sole nuclear weapons power.
Why it matters: France conducted its first-ever M51.3 test on the same timeline as Macron's push to recruit European partners into Paris's nuclear deterrent framework — with France as the EU's sole nuclear power. The dual move strengthens France's independent second-strike credibility while offering allies a nuclear umbrella option outside NATO's existing arrangements, a significant escalation of Paris's leadership claim in European defense at a time of strategic depth.
