The Triomphant class SSBN is the active lead boat class of the French Navy.

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 provide the ocean-based component (the Force océanique stratégique) of France's nuclear deterrent strike force, the Force de Frappe.

All SSBN's are based at Ile Longue, Brest, Western Brittany.

The first three boats are all armed with the French-produced and armed M45 intermediate-range missile, and the fourth vessel, Terrible, has tested and is equipped with the more advanced M51 missile. Each of the first three boats are to be retrofitted to the M51 missile standard, starting with Vigilant in 2010, then Triomphant, and ending with Téméraire in 2018.

They have replaced the six Redoutable-class Ballistic Missile Submarines.

This class reportedly produces approximately 1/1000 of the detectable noise of the Redoutable-class SSBN's, and they are ten times more sensitive in detecting other submarines.
