M1 (missile)

Spacecraft and Launch Vehicles

The M1 MSBS was the first French submarine-launched ballistic missile. MSBS stands for Mer-Sol Balistique Stratégique, or sea-ground strategic ballistic missile, and the M1 had two stages. It was deployed on the Redoutable-class nuclear ballistic missile submarines, known in French as SNLE, from 1971 to 1975, and was then replaced by the M2 in 1974 and 1975. The M1 opened the MSBS family that gave France the sea-based leg of its nuclear deterrent, a line that went on through the M2, M20, M4 and M45 missiles and was later succeeded by the M51.
