Defense Atomic Support Agency, Lake Mead Base, Las Vegas, NV

The Defense Atomic Support Agency (DASA) operated a facility at Lake Mead Base near Las Vegas, Nevada, during the height of the Cold War. Established in the late 1950s, the base supported DASA’s mission of overseeing and coordinating U.S. nuclear weapons testing and related activities, particularly at the nearby Nevada Test Site. Personnel at Lake Mead Base provided logistical, scientific, and technical support for atomic test operations, including radiological safety and data collection. The base remained active into the early 1970s, contributing to America's nuclear readiness before its functions were absorbed by successor agencies.
