The Atomic Museum is one of a handful of private national museums and showcases some of the rarest of artifacts relating to the nation’s atomic testing program. Nowhere else can you see a large nuclear reactor that was used in the development of the nuclear rocket and the first air-to-air missile, Genie. Personal atomic weapons that were developed to use in place of conventional weapons such as the Backpack Nuke and the Davy Crockett Weapon System (recoilless gun) are placed throughout the 8,000 square feet of museum exhibits.
