The Triomphant class of ballistic missile submarines of the French Navy is the active lead boat class of four boats that entered service in 1997, 1999, 2004, and 2010. These four superseded the older Redoutableclass, and they provide the ocean-based component (the Force océanique stratégique ) of France's nuclear deterrent strike force, the Force de dissuasion (deterrence force). Their home port is Île Longue, Roadstead of Brest, Western Brittany.
The first three boats were originally armed with the French-produced and armed M45 intermediate-range missile, and the fourth vessel, Le Terrible, tested and is equipped with the more advanced M51 missile.Each of the first three boats were retrofitted to the M51 missile standard, with the last M45 offloaded in 2016.
In French, these are called Sous-Marin Nucléaire Lanceur d'Engins de Nouvelle Génération (English: "Next Generation Device-Launching Nuclear Submarine"), abbreviated as SNLE-NG. They have replaced all of the Redoutable-class boats, with the last of those six boats being decommissioned in 2008. These submarines carry 16 submarine-launched ballistic missile launching tubes apiece.
This class reportedly produces approximately 1/1000 of the detectable noise of the Redoutable-class boats (submarines), and they are ten times more sensitive in detecting other submarines. As of October 2010 [update] , an M51 has been test-fired from one of these submarines across the Atlantic Ocean from near France to the west, and is equipped on Le Terrible.Initially armed with the M45 missile, they are designed to carry the new M51 missile, which entered active service in 2010.
These boats were all constructed by the DCNS, and they carry an armament of 16 M45 SLBM or M51 SLBM missiles manufactured by the Aérospatiale company (now Airbus Defence and Space), plus conventional torpedoes and Exocet anti-ship missiles.
The French Navy's goal is to operate a force of four ballistic missile submarines (comparable with the Royal Navy's Vanguard-class submarines), of which two are expected to be on patrol at any given time.

On 3 February or 4 February 2009, Le Triomphant collided with the Royal Navy submarine HMS Vanguard; the Royal Navy boat received damage to the outer casing in the area of the missile compartment on the starboard (right) side and suffered very visible dents and scrapes. Le Triomphant was reported to have proceeded to Brest under her own power, submerged, but with damage to her active sonar dome under her bow.
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the SS denotes submarine, the B denotes ballistic missile, and the N denotes that the submarine is nuclear powered. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect, thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence.
The Force de frappe, or Force de dissuasion after 1961, is the designation of what used to be a triad of air-, sea- and land-based nuclear weapons intended for dissuasion, the French term for deterrence. The French Nuclear Force, part of the French military, is the third largest nuclear-weapons force in the world, after the nuclear triads of the United States and the Russian Federation.
The TN 75 is a French-built 150kt thermonuclear warhead used on France's M45 and M51 submarine-launched ballistic missiles, carried by the last of the Redoutable class submarines, S616 Inflexible, and by the Triomphant class submarines. The French Navy has 290 TN-75 warheads. It is a miniaturized, hardened and stealthy successor to the TN 71.
The M4 was a French submarine-launched ballistic missile (SLBM) deployed on the nuclear Redoutable-class submarines.
The M45 SLBM was a French Navy submarine-launched ballistic missile Forty-eight M45 were in commission in the Force océanique stratégique, the submarine nuclear deterrent component of the French Navy. The missiles, derived from the M4, were produced by Aérospatiale. Initially, an ICBM land-based version was considered, but these plans were discarded in 1996 to favour an all-naval deployment.
L'Inflexible is the sixth and final of the Redoutable-class SNLE of the Force océanique stratégique (FOST), the submarine nuclear deterrent component of the French Navy.
The Le Redoutable-class submarine was a ballistic missile submarine class of the French Marine Nationale. In French, the type is called Sous-marin Nucléaire Lanceur d'Engins (SNLE), literally "Missile-launching nuclear submarine". When commissioned, they constituted the strategic part of the naval component of the French nuclear triad, then called Force de frappe.
The M51 SLBM is a French submarine-launched ballistic missile, built by ArianeGroup, and deployed with the French Navy. Designed to replace the M45 SLBM, it was first deployed in 2010.
Le Redoutable was the lead boat of her class of ballistic missile submarines in the French Marine Nationale.
The M1 MSBS was the first French submarine-launched ballistic missile.
The Strategic Ocean Force has been the synonym of the French Submarine Forces since 1999, which the commandant commands the ensemble related to, along with the squadron of nuclear attack submarine.
The M20 was a French submarine-launched ballistic missile (SLBM) deployed on the nuclear Redoutable-class submarines from 1977. It was withdrawn from service by 1991.
Le Triomphant is a strategic nuclear submarine of the French Navy; the submarine is the lead boat of her class commissioned in 1997 with the home port of Île Longue. The vessel carries sixteen strategic missiles, whose launch can only be authorized by the President of France.
Le Téméraire is a Triomphant-class ballistic missile submarine of the French Navy, launched in January 1998, and commissioned in December 1999, six months behind schedule. The boat had, in May 1999, successfully test launched an M45 submarine-launched ballistic missile.
Le Vigilant is a Triomphant-class strategic nuclear submarine in service with the French Navy.
Le Terrible is a Triomphant-class strategic nuclear submarine of the French Navy. The boat was launched on 21 March 2008
The Submarine Forces of France are one of the four main components of the French Navy. The force oversees all French submarines regardless of role.
The submarines HMS Vanguard of the Royal Navy and Le Triomphant of the French Navy collided in the Atlantic Ocean in the night between 3–4 February 2009. Both nuclear-powered ballistic missile submarines sustained damage, but no injuries or radioactivity releases were reported. At the time of the collision, both vessels were submerged and moving "at very low speed" according to the UK Ministry of Defence. Both are equipped with active and passive sonar, although only the latter is used on an operational patrol.
The M2 MSBS was the second French submarine-launched ballistic missile. In French, MSBS is the abbreviation for Mer-Sol Balistique Stratégique, or Sea-Ground Strategic Ballistic Missile. It has two stages. It was deployed on the Redoutable-class SNLEs or SSBNs from 1974 to 1978, replacing the M1 MSBS. The M2 was itself replaced by the M20 MSBS beginning in 1977.
The SNLE 3G is a class of submarines under development for the French Navy's nuclear deterrent, part of the Force de dissuasion. It is being designed as a replacement for the current Triomphant class beginning around 2035, and could remain in service to as late as 2090.
