Operation Plumbbob (nonfiction)

Operation Plumbbob nuclear weapons test Priscilla, detonated on June 24, 1957.

Operation Plumbbob was a series of nuclear tests conducted by the United States between May 28 and October 7, 1957, at the Nevada Test Site, following Project 57, and preceding Project 58/58A.

It was the biggest, longest, and most controversial test series in the continental United States.

The Rainier shot, conducted September 19, 1957, was the first fully contained underground nuclear test, meaning that no fission products were vented into the atmosphere. This test of 1.7 kt could be detected around the world by seismologists using ordinary seismic instruments. The Rainier test became the prototype for larger and more powerful underground tests.
