About FAS 

The Federation of American Scientists (FAS) works to provide science-based analysis of and solutions to protect against catastrophic threats to national and international security. Specifically, FAS works to reduce the spread and number of nuclear weapons, prevent nuclear and radiological terrorism, promote high standards for nuclear energy’s safety and security, illuminate government secrecy practices, as well as track and eliminate the global illicit trade of conventional, nuclear, biological and chemical weapons.  FAS was founded in 1945 by many of the Manhattan Project scientists who wanted to prevent nuclear war and is one of the longest serving organizations in the world dedicated to reducing nuclear threats and informing the public debate by providing technically-based research and analysis on these issues.

FAS is a non-profit membership organization, with members from the academic, non-profit and government communities. For more information on FAS membership and to join, please visit our Membership page.
