Formerly known as the Nevada Proving Grounds of the United States Army, the site was acquired in 1951 to be the testing venue for the American nuclear devices. The first atmospheric test was conducted at the site's Frenchman Flat area by the United States Atomic Energy Commission (USAEC) on January 27, 1951.
The final test at Yucca Flat (also the last test at the entire Nevada Test Site) was Operation Julin's "Divider" on September 23, 1992, just prior to the moratorium temporarily ending all nuclear testing. Divider was a safety experiment test shot that was detonated at the bottom of a shaft sunk into Area 3.

The knowledge gained provided data to prevent nuclear yields in case of accidental detonations—for example, in a plane crash. The John shot on July 19, 1957, was the only test of the Air Force's AIR-2A Genie rocket with a nuclear warhead. [3] It was fired from an F-89J Scorpion fighter over Yucca Flats at the Nevada National Security Site.
