Nuclear Legacies: Public Understanding and FAS
“In late 1945, a group of scientists who had been involved with the Manhattan Project felt it was their civic duty to help inform the public and political leaders of both the potential benefits and dangers of nuclear energy. To facilitate this important work, they established the Federation of Atomic Scientists, which soon became the Federation of American Scientists. Over the years, FAS has evolved into a model non-governmental organization that plays a leading role in providing scientifically-sound, non-partisan analyses of nuclear and broader security issues. I have long admired FAS and was therefore deeply honored when President Charles D. Ferguson asked if I would be interested in preparing a brief essay for a special edition of the PIR that would commemorate the organization’s 70th anniversary. A period of mild apprehension then followed: What could I say on the relationship between science and society that had not been said a thousand times before?”
The SIPRI chapter describes the nuclear weapon modernization programs underway in each nuclear-armed state and provides estimates for how many nuclear warheads each country possesses.
FAS researchers Hans Kristensen and Matt Korda with the Nuclear Information Project write in the new SIPRI Yearbook 2024, released today.
The total number of U.S. nuclear warheads are now estimated to include 1,770 deployed warheads, 1,938 reserved for operational forces. An additional 1,336 retired warheads are awaiting dismantlement, for a total inventory of 5,044 warheads.
A military depot in central Belarus has recently been upgraded with additional security perimeters and an access point that indicate it could be intended for housing Russian nuclear warheads for Belarus’ Russia-supplied Iskander missile launchers.
