By Hans M. Kristensen Although the U.S. Navy has yet to make a formal announcement that the nuclear Tomahawk land-attack cruise missile (TLAM/N) has been retired, a new updated navy instruction shows that the weapon is gone. The evidence comes not in the form of an explicit statement, but from what has been deleted from […]
Researchers from the Federation of American Scientists (FAS) asked two physicists who are experts in missile defense issues, Dr. Yousaf Butt and Dr. George Lewis, to weigh in on the announcement on March 15, 2013 regarding missile defense by the Obama administration. Before exploring their reactions and insights, it is useful to identify salient elements […]
The Highly Pathogenic Avian Influenza (HPAI) H5N1 virus poses a public health threat in many regions of the world. Approximately 600 human cases have been reported since 2003, with a laboratory-confirmed case fatality rate of up to 60% according to the World Health Organization (WHO). The recent death of a woman from southwest China, attributed to H5N1, has […]

I will argue (prepared remarks here) that the United States could make more unilateral nuclear arms reductions in the future, as it has safely done in the past, as […]
By Hans M. Kristensen The United States has quietly reduced its nuclear weapons stockpile by nearly 500 warheads since 2009. The current stockpile size represents an approximate 85-percent reduction compared with the peak size in 1967, according to information provided to FAS by the National Nuclear Security Administration (NNSA). The reduction is unilateral and not […]
By Hans M. Kristensen The National Nuclear Security Administration (NNSA) expects additional delays in production and delivery of the B61-12 nuclear bomb as a result of so-called sequestration budget cuts. During testimony before the Hours Energy and Water Subcommittee last week, NNSA’s Acting Administrator Neile Miller said an expected $600 million reduction of the agency’s […]
On December 12, 2012, North Korea finally succeeded in placing an object into low Earth orbit. Recovered debris of the launcher’s first stage verified some previous assumptions about the launch system, but it also included some surprises. Independent from the technical findings and their consequences, the public debate seems to miss some important points. Fundamental […]
By Hans M. Kristensen When the news media reported that a meteor had exploded over Chelyabinsk in Russia, the location name sounded familiar: the region is home to some of Russia’s most important nuclear weapons production and storage facilities. Impact sites still have to be found but one reportedly was Chebarkul Lake, some 72 kilometers […]
.By Hans M. Kristensen The United States and Russia have some 1,800 nuclear warheads on alert on ballistic missiles that are ready to launch in a few minutes, according to a new study published by UNIDIR. The number of U.S. and Russian alert warheads is greater than the total nuclear weapons inventories of all other […]
