Generality

The Strategic Ocean Force (), created on March 1, 1972, constitutes the principal composite of the Strategic French Nuclear Forces (). FOST was placed under the command of a Squadron Vice-Admiral (Officers of Admiral rank) (), hence the acronym ALFOST. With the dissolution of the Atlantic Attack Submarine Group, the submarines with conventional propulsion were grouped with the nuclear submarines from July 1, 1999.

capability). Since 1985, the strategy of nuclear deterrence in France armed six French nuclear ballistic missile submarines in service, five in service since 1991, and four since 1997; maintaining a permanent presence around the oceans and seas. Deterrence is ensured in 2014 by the permanent deployment of the French nuclear ballistic missile submarines of the ''Triomphant''-class. Between 1972 and April 2014, hundreds of patrols were realized. The first submarine class of French nuclear ballistic missile submarines in service was the ''Redoutable'' class, the head of the series, which was put in dry-docks under authorization in March 1963, with construction commencing in 1964 and was launched on March 29, 1967, in presence of

Charles de Gaulle. Trials of theclass commenced in 1969 and the boat entered into service on December 1, 1971. Six French nuclear ballistic missile submarines of the ''Redoutable'' class capable of carrying sixteen ballistic missiles were built: * ''Le Redoutable'' (in service 1971–1991) * ''Le Terrible'' (1973–1996) * ''Le Foudroyant'' (1974–1998) * '' L'Indomptable'' (1976–2003) * ''Le Tonnant'' (1980–1999) * ''L'Inflexible'' (1985–2008) Four French nuclear ballistic missile submarines of a newer generation, the ''Triomphant'' class, are in service in 2013 in the '' force océanique stratégique'' of the

''Le Terrible'' was presented on March 21, 2008, and entered service at the end of September 2010 to replace the ''L'Inflexible'', last of the retired ''Redoutable''-class ballistic missile submarine in 2008. The armament systems of the ballistic missile submarines include in general: * 16 M45 missiles with TN 75 warheads (nuclear deterrence). French nuclear deterrence also includes M51 missiles. * Four 533 mm tubes for F17 torpedoes and Exocet SM39 anti-ship missiles. The mission of a French nuclear ballistic missile submarine is simple: leave the designated port of attachment, in the most discreet possible way, remain undetectable all along the mission to be able at any moment launch a nuclear strike, under orders of the President of France.
