The missile, a variant of the country’s existing M51 series, was launched from the submarine Le Vigilant off the coast of Brittany. According to officials, it impacted “in the North Atlantic, hundreds of kilometres from any coastline,” ensuring safety during the trial. The ministry confirmed that the missile was not carrying a warhead during the test.

French President Emmanuel Macron personally witnessed the launch, underscoring the strategic importance of the trial for France’s national defence and nuclear deterrence program. The M51.3 represents the latest upgrade in France’s long‑range missile arsenal, designed to enhance precision, range, and reliability.

Defence experts say the test highlights France’s commitment to maintaining a credible nuclear deterrent amid rising global security challenges. The successful firing also reinforces the country’s position as one of the few nations with advanced submarine‑launched ballistic missile capabilities.

The Defence Ministry described the operation as a “major milestone” in France’s defence modernization strategy, with further trials expected before the missile is fully integrated into active service.
