Mission of the NNSS
The Nevada National Security Sites and its related facilities help ensure the security of the United States and its allies by: supporting the stewardship of the nation’s nuclear deterrent; providing nuclear and radiological emergency response capabilities and training; contributing to key nonproliferation and arms control initiatives; executing national-level experiments in support of the National Laboratories; working with national security customers and other federal agencies on important national security activities; and providing long-term environmental stewardship of the NNSS’s Cold War legacy.
A Premier National Security Resource
Located in a remote, highly secure area of southern Nevada, the NNSS is a premier outdoor, indoor, and underground national laboratory. It is a preferred location for experiments supporting the National Nuclear Security Administration (NNSA)’s nuclear weapons Stockpile Stewardship Programs, national defense programs, and national security research, development and training programs, as well as vital programs of other federal agencies.
