By Hans M. Kristensen Two suspected terrorists arrested by the Italian police allegedly were planning an attack against the nuclear weapons base at Ghedi. The base stores 20 US B61 nuclear bombs earmarked for delivery by Italian PA-200 Tornado fighter-bombers in war. Nuclear security and strike exercises were conducted at the base in 2014. During […]
By Muhammad Umar, On July 14, 2015, after more than a decade of negotiations to ensure Iran only use its nuclear program for peaceful purposes, Iran and the P5+1 (US, UK, Russia, China, France + Germany) have finally agreed on a nuclear deal aimed at preventing Iran from developing nuclear weapons. Iran has essentially agreed to […]
By Hans M. Kristensen The biggest surprise in the Pentagon’s latest annual report on Chinese military power is the claim that China’s ICBM force now includes the “multiple independently-targetable re-entry vehicle (MIRV)-equipped Mod 3 (DF-5).” This is (to my knowledge) the first time the US Intelligence Community has made a public claim that China has […]
By Hans M. Kristensen In a speech to the Review Conference of the Non-Proliferation Treaty in New York earlier today, U.S. Secretary of State John Kerry disclosed new information about the size of the U.S. nuclear weapons stockpile. Updated Stockpile Numbers First, Kerry updated the DOD nuclear stockpile history by declaring that the stockpile as of […]
By Hans M. Kristensen Is China increasing production of nuclear ballistic missile submarines? Over the past few months, several US defense and intelligence officials have stated for the record that China is planning to build significantly more nuclear-powered missile submarines than previously assumed. This would potentially put a bigger portion of China’s nuclear arsenal out […]
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. […]
By Hans M. Kristensen Russian online news paper Vzglaid is carrying a story that wrongly claims that I have said a Russian flight-test of an INF missile would not be a violation of the INF Treaty as long as the missile is not in production or put into service. That is of course wrong. I […]
Despite the extensive data obtained through the conduct of more than 1000 nuclear explosive tests, there is still much that is unknown or imperfectly understood about the science of nuclear weapons. A newly disclosed report prepared in 2011 by the JASON science advisory panel assessed efforts by the National Nuclear Security Administration (NNSA) to “develop […]
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 […]
