By Hans M. Kristensen Russian nuclear weapons have received a lot of attention lately. Russian officials casually throw around direct or thinly veiled nuclear threats (here, here and here). And U.S. defense hawks rail (here and here) about a Russian nuclear buildup. In reality, rather than building up, Russia is building down but appears to be […]
By Hans M. Kristensen Russian deployed strategic warheads counted by the New START Treaty once again slipped below the U.S. force level, according to the latest fact sheet released by the State Department. The so-called aggregate numbers show that Russia as of March 1, 2015 deployed 1,582 warheads on 515 strategic launchers. The U.S. count […]
Physicist Kenneth W. Ford, who participated in the design of the hydrogen bomb in the early 1950s, has published a memoir of his experiences despite the objections of Energy Department reviewers who requested substantial redactions in the text. “Building the H Bomb: A Personal History” was released this month in softcopy by World Scientific Publishing Company.

It has become popular among military and congressional leaders to argue that the United States has had a “procurement holiday” in nuclear force planning for the past two decades. “Over the past 20-25 years, we took a procurement holiday” in modernizing U.S. nuclear forces, Major General Garrett Harencak, the Air Force’s assistant chief of staff […]
The U.S. government will not categorically declassify the number of weapons in the U.S. nuclear arsenal once and for all, but it will consider declassification of the size of the prior year’s arsenal on a case by case basis, the Department of Energy said last week. In May 2010, the Obama Administration declassified the fact […]
The news media and private web sites are full of rumors that Russia has deployed nuclear weapons to Crimea after it invaded the region earlier this year. Many of these rumors are dubious and overly alarmist and ignore that a nuclear-capable weapon is not the same as a nuclear warhead. Several U.S. lawmakers who oppose […]
By Hans M. Kristensen For the next week I’ll be in Vienna for the Conference on the Humanitarian Impact of Nuclear Weapons. This is the third in a series of conferences organized and attended by a growing number of countries and humanitarian organizations to discuss the unique risks nuclear weapons pose to humanity and life […]
