The M1 MSBS was the first French submarine-launched ballistic missile.

In French, MSBS is the abbreviation for Mer-Sol Balistique Stratégique, or Sea-Ground Strategic Ballistic Missile.

It was deployed on the Redoutable-class SNLEs (Sous-marin Nucléaire Lanceur d'Engins) (Device-launching Nuclear Submarine) or SSBNs from 1971 to 1975.
