It is situated within the Nevada National Security Site and was constructed by the Atomic Energy Commission to house and service the staff of the test site.
Sedan was a thermonuclear device with a fission yield less than 30% and a fusion yield about 70%. [3] [4] According to Carey Sublette, the design of the Sedan device was similar to that used in the Bluestone and Swanee tests of Operation Dominic conducted days and months prior to Sedan respectively, and was therefore not unlike the W56 high yield Minuteman I missile warhead.

On this day in 1957, the first underground nuclear test was carried out at the Nevada Test Site, a 1,375 square-mile research center located 65 miles away from Las Vegas.The 1,7 kiloton nuclear ...
Frenchman Flat is a hydrographic basin in the Nevada National Security Site [2] south of Yucca Flat and north of Mercury, Nevada. The flat was used as an American nuclear test site and has a 5.8 sq mi (15 km 2 ) dry lake bed (Frenchman Lake) that was used as a 1950s airstrip before it was chosen after the start of the Korean War for the Nevada ...
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.
Wind dispersed radioactive fallout from those atmospheric blasts (mushroom clouds) and underground testing (venting) in a seemingly unpredictable manner to people living “downwind.”
Operation Project 58/58A [1] was a series of 4 nuclear tests conducted by the United States in 1957–1958 at the Nevada Test Site. These tests followed the Operation Plumbbob series and preceded the Operation Hardtack I series. All the tests in Project 58 were one-point safety tests. [2]
