France managed to research and develop its own nuclear weapon in 1960. The test, known as, Gerboise Bleue, was the result of mostly French research. One of the main figures that played crucial role in the entire process of developing the bomb was General Pierre Marie Gallois. He was concerned that the Suez Crisis, which started in 1956, would show the world how insignificant France became, since out of all Great Powers in the world, they were the only one without possessing its own nuclear arsenal. The tests were conducted on the terrains of Sahara Desert.
At this moment France owns 300 nuclear warheads, out of which almost all are deployed. What is more, compared to Great Britain, they made more tests, approximately 210. Noteworthy is the fact that the development of the first nuclear bomb in France as well as its tests were a bit controversial. It was due to the fact that France allowed Israeli observers to attend the tests, providing them with almost unrestricted access to all the data. It was quite important, since Israel, together with United Kingdom and France, were trying to invade Egypt.
