Main Gallery



Now open inside the Atomic Museum is “SPY,” a brand-new boutique exhibit in partnership with the National Security Agency’s (NSA) National Cryptologic Museum in Fort Meade, Maryland. “SPY” spotlights how the NSA’s gathering of telemetry intelligence, which is used to obtain data on the internal functioning of missiles and space vehicles being tested by foreign governments, allowed the United States to keep pace with ever-changing technology.

Several artifacts relate to ensuring compliance with START I, which was the bilateral treaty signed in 1991 between the United States and the Soviet Union regarding the reduction and limitation of strategic offensive arms.

Diagnostic Rack

Gaze up at the towering model of a diagnostic rack in our underground testing gallery. These racks would have held nuclear weapons and other equipment in place in massive holes as deep as 2000 feet.


Marvel at a real Phoebus-2A nuclear reactor that was built as part of Project Rover. Phoebus-2A was the most powerful nuclear propulsion reactor designed for the project. Scientists at the time thought that this prototype could be modified to send astronauts to Mars.
