In 1957, the sixth in a series of weapons tests took place at the Nevada Test Site. The Plumbbob tests consisted of 24 full size atomic detonations and six "safety experiments" and was the peak of atmospheric testing at the Nevada Test Site. There were 21 laboratories and government agencies involved.

The explosions were to test new weapon designs and included 43 military effects tests on civil and military structures, radiation and bio-medical studies, and aircraft structural tests. The Air Force, Army, Navy and Marines continued the Desert Rock Excercises, number VII and VIII with 18,000 personnel.
