It’s a funny thing: the administrations that talk the most about reducing nuclear weapons tend to reduce the least.
The U.S. Nuclear Weapons Council has selected the W80-1 thermonuclear warhead for the Air Force’s new nuclear cruise missile (Long-Range Standoff, LRSO) scheduled for deployment in 2027. The W80-1 warhead is currently used on the Air Launched Cruise Missile (ALCM), but will be modified during a life-extension program and de-deployed with a new name: W80-4. […]
The transcript of the momentous 1954 Atomic Energy Commission hearing that led the AEC to revoke the security clearance of J. Robert Oppenheimer, the physicist who had led the Manhattan Project to produce the first atomic bomb, has now been declassified in full by the Department of Energy. “The Department of Energy has re-reviewed the […]

By Hans M. Kristensen In December 1963, a shipment of U.S. nuclear bombs arrived at Ghedi Torre Air Base in northern Italy. Today, half a century later, the U.S. Air Force still deploys nuclear bombs at the base. The U.S.-Italian nuclear collaboration was celebrated at the base in January. A placard credited the nuclear “NATO […]

By Hans M. Kristensen One of the last Chinese Second Artillery brigades with the old liquid-fuel DF-3A intermediate-range nuclear ballistic missile appears to have been upgraded to the newer DF-21 road-mobile, dual-capable, medium-range ballistic missile. A new satellite image posted on Google Earth from May 4, 2014, reveals major changes to what appears to be […]
