When did France first test nuclear weapons?

The first French nuclear test was Gerboise Bleu on February 13, 1960 at 06:04 Greenwich Mean Time. The test was conducted near Reganne in the Algerian Sahara desert in Africa. It was a tower shot from a 105-meter tower. The test device was a single-point implosion-type plutonium device and had a yield of between 60 and 70 kilotons (as predicted). It was the largest first test by the nuclear powers of the time.
