The M20 was a French submarine-launched ballistic missile deployed on the nuclear Redoutable-class submarines from 1977 and withdrawn from service by 1991. It was the third member of the MSBS family (Mer-Sol-Balistique-Stratégique, sea-ground ballistic strategic) of intermediate-range missiles that make up the second leg of the French nuclear deterrent force. The M20 was a two-stage, solid propellant missile 10.4 metres long and 1.5 metres in diameter, with a launch weight of 20,000 kilograms, a range of 3,000 kilometres and inertial guidance. Its single re-entry vehicle carried a TN-60 warhead reported at 1.2 megatonnes. About 100 missiles were produced, and the M20 was largely succeeded by the M4 and M45.
