About FAS

About FAS

The Federation of American Scientists is a nonpartisan, nonprofit policy research and advocacy organization founded in 1945 to meet national security challenges with evidence-based, scientifically-driven policy and expertise. 

Over 75 years later, we are still working to minimize the risks of significant threats – arising from nuclear weapons, biological and chemical agents, and climate change – as well as addressing a broad suite of contemporary issues and challenges where science, technology, and innovation policy can deliver dramatic progress and prevent catastrophic harm. 


Our Story

After the devastating bombings of Hiroshima and Nagasaki, a group of atomic researchers, deeply concerned about the use of science for harm, decided to create an organization committed to using science and technology to benefit humanity. The group they created – the Federation of Atomic Scientists – mobilized to transform policy with scientific expertise. In 1946, the group rebranded as the Federation of American Scientists in recognition of the hundreds of scientists across diverse disciplines who joined together to advance science policy and counter scientific misinformation.


Issues We’re Tackling

Our founders recognized that data-driven policy and security go hand-in-hand. The diverse work at FAS offers evidence-based analysis and solutions for the most pressing policy and security challenges of today.



  • The Nuclear Information Project tracks global nuclear arsenals and nuclear arms control treaties, to reduce the existential threat of nuclear war.
  • The Defense Posture Project monitors rapid advancements in military technology that challenge existing concepts of deterrence.


  • The Congressional Science Policy Initiative provides evidence-based analysis of science and technology issues to Members of Congress, mobilizing experts and connecting them directly with policymakers.
  • The Organs Initiative uses data science to accelerate improved patient outcomes.
