France fires its newest nuclear missile from a submarine

France successfully test-fired its newest submarine-launched nuclear missile, the M51.3, on October 6. President Emmanuel Macron observed the operation from a French Navy frigate off the coast of Brittany. The missile was launched from the submarine Le Vigilant off Finistère, eventually landing in the North Atlantic. This upgraded nuclear missile test occurred amidst ongoing tensions with Russia, marking the first time the M51.3 has been deployed from a ballistic missile submarine during a live exercise.
