The Force de frappe (French for: strike force), or Force de dissuasion after 1961, is the designation of what used to be a triad of air-, sea- and land-based nuclear weapons intended for dissuasion, the French term for deterrence. The French Nuclear Force, part of the Armed Forces of France, is the third largest nuclear-weapons force in the world, following the nuclear triads of the Russian Federation and the United States.
France has deactivated all land-based nuclear missiles. On 27 January 1996, France conducted its last nuclear test (in the South Pacific) before signing the Comprehensive Nuclear-Test-Ban Treaty (CTBT) in September 1996. In March 2008, President Nicolas Sarkozy confirmed reports giving the actual size of France's nuclear arsenal and he announced that France would reduce its French Air Force-carried nuclear arsenal by 30%, leaving the Force de Frappe with 290 warheads.
In addition to its nuclear military programme, France has a large peaceful nuclear programme and ranks as one of the world's largest generators of nuclear power.
The decision to arm France with nuclear weapons was made in 1954 by the administration of Pierre Mendès-France under the Fourth Republic.President Charles de Gaulle, upon his return to power in 1958, solidified the initial vision into the well-defined concept of a fully independent Force de Frappe capable of protecting France from a Soviet or other foreign attack, independent of the North Atlantic Treaty Organization, which President de Gaulle considered to be dominated by the United States to an unacceptable degree. In particular, France was concerned that in the event of a Soviet invasion of Western Europe, the US—already bogged down in the War in Vietnam and afraid of Soviet retaliation against the United States proper—would not come to the aid of its Allies in Western Europe. According to de Gaulle, France should never trust its defense and therefore its very existence to a foreign and thus unreliable protector.
