France test-fired its new M51.3 nuclear-capable ballistic missile from a submarine on Tuesday, October 6, 2026. The missile was fired from the Le Vigilant submarine off Brittany and impacted in the North Atlantic, hundreds of kilometres from any coastline.

The test was witnessed by President Emmanuel Macron from a French warship. The Defence Ministry said the launch was conducted without a nuclear warhead and in strict compliance with France's international commitments.
