PARIS — France carried out the inaugural submarine launch of an upgraded M51 strategic ballistic missile on Tuesday, a demonstration of capability that President Emmanuel Macron described as “very important” for Paris’s strategic credibility and one he said would draw close attention from both allies and rivals.
The nuclear-powered ballistic-missile submarine Le Vigilant released an M51.3 in what the Ministry of the Armed Forces described as an acceptance test after the vessel’s refit. The missile — flown without a nuclear warhead — was launched off the coast of Finistère in western France and fell into the North Atlantic several hundred kilometers from the nearest shore, the ministry said.
France’s enhancement program for the M51, produced by ArianeGroup, forms part of a wider renewal of its nuclear deterrent. That broader effort also encompasses building new ballistic-missile submarines and plans to upgrade Rafale fighters so they can carry a future hypersonic nuclear cruise missile.
“This is a very important moment for our strategic credibility,” Macron told personnel aboard a French Navy ship from which he observed the firing. He added that recent events and Tuesday’s demonstration would be scrutinized by friends and foes alike, calling the test a further step along the country’s chosen trajectory.
Paris’s modernization drive for its nuclear forces is taking place alongside cooperation with several European partners on what Macron has termed “forward deterrence,” a concept that could entail extending some aspects of French nuclear deterrence to those partners, though concrete details have not yet been defined.
The ministry told Defense News by email that every major overhaul of a French nuclear-powered ballistic-missile submarine is followed by an M51 acceptance firing, as part of the post-refit validation process.
ArianeGroup and France’s Directorate General for Armament carried out an initial flight test of the updated M51 at the Biscarrosse launch range in southwest France in 2023, and the upgraded missile entered service in October of last year.
Observers estimate the newest M51.3 has a range exceeding 9,500 kilometers, up from the more than 9,000 kilometers attributed to the prior variant, according to the Bulletin of the Atomic Scientists. The missile is reported to be able to deliver four to six independently targetable reentry vehicles (MIRVs), the Bulletin added.
While France does not publish an official maximum range, ArianeGroup states that the M51 climbs to altitudes beyond 2,000 kilometers before reentering the atmosphere at speeds around Mach 20.
The weapon is fitted with the new TNO-2 oceanic nuclear warhead and, the ministry says, offers enhanced range, accuracy and capability to penetrate defenses. The three-stage, solid-propellant missile weighs in excess of 50 metric tons, and each of France’s four ballistic-missile submarines can carry up to 16 missiles.
“The M51.3 preserves the long-term credibility of the sea-based leg in the face of evolving adversary missile defenses,” the ministry said, adding that the upgrade reflects presidential commitment to keeping the nuclear forces operationally credible over the long term, at the level demanded by the international security environment.
The original M51 was test-launched from Biscarrosse in 2006, and the first submarine launch took place from the SSBN Le Terrible in January 2010. Tuesday’s event marked the seventh time a variant of the M51 has been fired from a French submarine and the 13th overall launch of the missile series — all conducted, the ministry stressed, without nuclear warheads.
