February 13, 1960With the success of a nuclear test codenamed "Gerboise Bleue", France becomes the fourth country to possess nuclear weapons.
Gerboise Bleue ("blue jerboa") was the name of the first French nuclear test. It was an atomic bomb detonated in the middle of the Algerian Sahara desert on 13 February 1960, during the Algerian War (1954–62). General Pierre Marie Gallois was instrumental in the endeavour, and earned the nickname of père de la bombe A ("father of the A-bomb"). Gerboise is the French word for jerboa, a desert rodent found in the Sahara, while blue is the first color of the French tricolor flag. So the second and third bombs were named respectively "white" (Gerboise Blanche) and "red" (Gerboise Rouge), the remaining colors of the flag.
