The Redoutable class submarine is a ballistic missile submarine class of the French Marine Nationale , the oceanic part (Force Océanique Stratégique, FOST) of the Force de frappe. In French, the type is called Sous-marin Nucléaire Lanceur d'Engins (SNLE), literally "Missile-launching nuclear submarine".

The class entered active service in 1971 with Le Redoutable, six submarines were built in total. All decommissioned. The structural changes in L'Inflexible have seen it regarded as a different class from the early boats. The class has been superseded by the Le Triomphant class, firing the larger M45 missile (M51 from around 2010).

The first submarine, Le Redoutable, was ordered in 1963, built at Cherbourg, launched in 1967 and commissioned in 1971. Later submarines were very heavily upgraded from 1985 to fire the 2nd generation MIRV capable M4 missile - Le Tonnant was recommissioned in 1987; L'Indomptable in 1989; Le Terrible in 1990; and Le Foudroyant in 1993.
