50 YEARS OF THE STRATEGIC OCEAN FORCE (FOST)
The Submarine Forces (FSM) and the Strategic Oceanic Force (FOST) are composed of about 4000 sailors, military and civilian, who operate 4 nuclear ballistic missile submarines (SSBNs), 6 nuclear attack submarines (SSNs), units providing their command, strategic communications and support.
Lurking in the ocean, equipped with 16 missiles, each carrying several nuclear warheads, the 4 SSBNs have been patrolling continuously for 50 years to ensure the permanence of nuclear deterrence at sea. They are grouped together within the FOST. Created on March 1, 1972, FOST is the naval component of strategic nuclear forces. The nuclear deterrent remains, as a last resort, the cornerstone of our security and the guarantee of our vital interests.
Formidable submarine chasers, SSNs are essential to the safety and support of the FOST as well as to the protection of a naval air force at sea. They can quickly reach a theatre of operations, stay there for a long time, discreetly or, if necessary, more conspicuously, gather intelligence, participate in special operations and, if necessary, use their weapons: torpedoes, anti-ship missiles, naval cruise missiles.
