France had been heavily involved in nuclear research before World War II through the work of the Joliot-Curies. This was discontinued after the war because of the instability of the Fourth Republic and lack of finances. [75] However, in the 1950s, France launched a civil nuclear research program, which produced plutonium as a byproduct.
A tacit moratorium on testing was in effect from 1958 to 1961 and ended with a series of Soviet tests in late 1961, including the Tsar Bomba, the largest nuclear weapon ever tested. The United States responded in 1962 with Operation Dominic , involving dozens of tests, including the explosion of a missile launched from a submarine.
