During the Cold War, the French nuclear deterrent was centered around the Force de frappea nuclear triad consisting of Dassault Mirage IV bombers carrying such nuclear weapons as the AN gravity bomb and the ASMP stand-off attack missile, Pluton and Hades ballistic missiles, and the Redoutable class submarine armed with strategic nuclear missiles.
The People's Republic of China became the fifth nuclear power on October 16, when it detonated a 25 kiloton uranium bomb in a test codenamed  at Lop Nur. In the late s, China began developing nuclear weapons with substantial Soviet assistance in exchange for uranium ore.

Cuban Missile Crisis[ edit ] Main article: The Soviet Union supported and praised Castro and his resistance, and the new government was recognized by the Soviet government on January When the United States began boycotting Cuban sugar, the Soviet Union began purchasing large quantities to support the Cuban economy in return for fuel and eventually placing nuclear ballistic missiles on Cuban soil.
