The size of the U.S. nuclear stockpile as of September 30, 2015 — 4,571 weapons — and the number of U.S. nuclear weapons that were dismantled in FY 2015 — 109 of them — were declassified and disclosed last week. The latest figures came as a disappointment to arms control and disarmament advocates who favor […]
By Hans M. Kristensen Shortly before President Barack Obama is scheduled to arrive for his historic visit to Hiroshima, the first of two Japanese cities destroyed by U.S. nuclear bombs in 1945, the Pentagon has declassified and published updated numbers for the U.S. nuclear weapons stockpile and warhead dismantlements. Those numbers show that the Obama administration […]
By Hans M. Kristensen The Pentagon’s latest annual report on Chinese military developments mainly deals with non-nuclear issues, but it also contains important new information about developments in China’s nuclear forces. This includes: The size of China’s ICBM force has been relatively stable over the past five years China has deployed a new version of a medium-range […]
From its inception 70 years ago, the founders and members of the Federation of American Scientists were reinventing themselves. Imagine yourself as a 26-year old chemist having participated in building the first atomic bombs. You may have joined because your graduate school adviser was going to Los Alamos and encouraged you to come. You may […]
The Federation of American Scientists (FAS) formed after the bombing of Hiroshima and Nagasaki, precisely because many scientists were genuinely concerned for the fate of the world now that nuclear weapons were a concrete reality. They passionately believed that, as scientific experts and citizens, they had a duty to educate the American public about the […]
On August 8, 2015, twenty-nine scientists sent a letter to President Obama in support of the agreement with Iran that would block (or at least significantly delay) Iran’s pathways to obtain nuclear weapons. This continues a tradition that began seventy years ago of scientists having a role in educating the public, advising government officials, and […]
From its beginning, the Federation of American Scientists has been immersed in policies and issues regarding government secrecy and censorship. By the time World War II broke out, the fission process had been observed, followed by detection of the neutron, and recognition of induced uranium fission. In the early 1940s, some scientists in the United […]
“I was chairman of FAS from 1962-63. Fifty-year-old memories are hopelessly unreliable and historically worthless. Fortunately, my mother preserved the letters that I wrote to her describing events as they happened. The letters are reliable and give glimpses of history undistorted by hindsight. Instead of trying to recall fading memories, I decided to quote directly […]
“I am sharing some memories of the period 1960-1970 when I served as FAS General Counsel. I start by echoing Freeman Dyson’s caution that 50-year old memories are unreliable. I first learned about FAS in late 1958 when my wife, Dr. Maxine Singer, a molecular biologist employed by NIH, shared with colleagues her concerns about […]
“When, in 1970, I descended from the FAS Executive Committee to become the chief executive officer, FAS had 1,000 members and an annual budget of $7,000 per year. The organization was very near death. During my 30 year tenure, FAS became a famous, creative, and productive organization….”
“When, at Jeremy Stone’s instigation, I was elected chair of the Federation of American Scientists in 1979, I had no idea what an adventure that I was about to embark upon. This adventure was triggered by President Reagan taking office in 1981 and resulted in FAS making significant contributions to ending the U.S.-Soviet nuclear arms […]
“Supporting and expanding on Frank von Hippel’s cogent and exciting narrative of some of the great accomplishments of the Federation of American Scientists, I detail below two endeavors, at least one of which may have had far-reaching impact. The first was the initiative of FAS Director (and later President) Jeremy J. Stone who, in 1971, […]
