France test-fires upgraded M51.3 nuclear missile from submarine for first time
France successfully test-fired the upgraded M51.3 strategic ballistic missile from the nuclear-powered submarine Le Vigilant off Finistère on October 6, 2026. The missile, which did not carry a nuclear warhead, splashed down in the North Atlantic. President Macron observed the launch and called it a very important moment for France's strategic credibility. The M51.3 has an estimated range of over 9,500 kilometers and carries four to six MIRVs with the new TNO-2 warhead.

France test-fires upgraded M51.3 nuclear-capable missile from submarine for first time
France successfully test-fired an upgraded version of its M51 strategic ballistic missile, the M51.3, from the nuclear-powered submarine Le Vigilant for the first time on Tuesday. The missile, which did not carry a nuclear warhead, was launched off Finistère in western France and splashed down in the North Atlantic. President Emmanuel Macron, who observed the launch, called it a very important moment for France's strategic credibility, noting it would be closely scrutinized by allies and competitors. The test was an acceptance firing following the submarine's overhaul. The M51.3, manufactured by ArianeGroup, has an estimated range of over 9,500 kilometers and carries four to six multiple independently-targetable reentry vehicles (MIRVs). It is equipped with the new TNO-2 oceanic nuclear warhead and offers improved range, accuracy, and penetration capability. The modernization is part of a broader effort to upgrade France's nuclear deterrence, including new submarines and a hypersonic nuclear cruise missile for the Rafale fighter jet, and aligns with Macron's proposal for 'forward deterrence' to extend French nuclear protection to European allies.

France conducted the first submarine-launched test of its upgraded M51.3 strategic ballistic missile on Tuesday, October 6, 2026, from the nuclear-powered ballistic-missile submarine Le Vigilant off Finistère in western France. The missile, manufactured by ArianeGroup, splashed down in the North Atlantic several hundred kilometers from any coastline and did not carry a nuclear warhead. President Emmanuel Macron, who observed the launch from a French Navy vessel, called it 'a very important moment for our strategic credibility' and said it would be closely scrutinized by allies and competitors. The M51.3 variant is estimated to have a range of over 9,500 kilometers, carries four to six multiple independently-targetable reentry vehicles (MIRVs), and is equipped with the new TNO-2 oceanic nuclear warhead. The test followed the submarine's overhaul and was an acceptance firing. The modernization is part of a broader French nuclear deterrence upgrade that includes new ballistic-missile submarines and a future hypersonic nuclear cruise missile for the Rafale fighter jet, and aligns with Macron's proposal for 'forward deterrence' to potentially extend French nuclear protection to European allies.

France tests modernized M51.3 nuclear missile; Macron says 'we are stronger'
France has confirmed the operational readiness of its nuclear submarine 'Le Vigilant' by test-firing the modernized M51.3 intercontinental ballistic missile off the coast of Brittany. The test, conducted without a nuclear warhead and in compliance with international obligations, aimed to verify the submarine's readiness after extensive maintenance. The launch occurs amid heightened tensions with Russia, following President Vladimir Putin's threat to use nuclear weapons to defend the exclave of Kaliningrad. NATO has stated its activities pose no threat to Russia. French President Emmanuel Macron called the test a clear signal, stating in a video on X: 'Today we are stronger.' He added, 'To be free, one must be feared. And to be feared, one must be powerful.' Macron had announced in March plans to expand France's nuclear arsenal and offered European partners closer cooperation on nuclear deterrence. France possesses approximately 290 nuclear warheads, the fourth-largest arsenal globally, compared to the UK's 225 and the US and Russia's over 5,000 each.
French Navy Conducts Acceptance Firing of M51.3 Missile From Le Vigilant SSBN
On October 6, 2026, the French Ministry of Defence announced the successful completion of the first acceptance firing of the M51.3 version of the M51 ballistic missile. The test was conducted from the nuclear-powered ballistic missile submarine (SSBN) Le Vigilant. The announcement was made via a French MoD press release, translated by Naval News. This event marks a key milestone in the development and qualification of the upgraded M51.3 missile, which is designed to enhance the capabilities of France's sea-based nuclear deterrent force.
