This Foreign Ministry analysis was written for French Foreign Minister Maurice Couve de Murville. It spells out the obstacles facing an independent deterrent two weeks after France’s first nuclear test on February 13, 1960. The author cautions that a “minor deterrent” of a few dozen 100-kilton atom bombs loaded on vulnerable, short-range Mirage IV A fighter-bombers would cost hundreds of billions of francs. Intermediate-range ballistic missiles with which to threaten Moscow would require an additional 8-10 years and a further cost of 500 billion francs (around $100 billion in 1960). In order to match the superpowers’ thermonuclear level, that figure could rise as a high as “several trillion” over more than a decade, during which time the United States and the Soviet Union might well leapfrog the French force de dissuasion.
