• U.S. has 5,113 strategic nuclear warheads -- down from 31,225 in 1967

    IN 1967 The United States had 31,255 strategic nuclear warheads in its arsenal; in 1989, the number fell to 22,217; today, the number of warhead is 5,113; the number of non-strategic, or tactical, nuclear weapons fell by 90 percent between 1991 and 2009

  • Risks of laser-based uranium enrichment outweigh rewards

    Researchers argue that laser-based uranium enrichment is not the way to bolster nuclear power: the technique, which involves the separation of isotopes by lasers, would save U.S. households no more than about $2 per month in energy costs, while increasing dramatically the risk of nuclear weapons proliferation

  • Northrop Grumman unveils latest version of Wheelbarrow UGV

    Northrop Grumman’s Wheelbarrow unmanned ground vehicle (UGV) was first used by British Army bomb disposal teams during “The Troubles” in Ireland in the 1970s; since then it has gone through a number of design upgrades to extend its capabilities and meet changing military and first response needs; the company has just unveiled the latest version of this veteran robot

  • Uranium-mining nations ignore UN-mandated measures on nuclear terror

    In the aftermath of the 9/11 terror attacks and the 2004 uncovering of the Pakistan-based A. Q. Khan nuclear smuggling network, the United States pushed Resolution 1540 through the UN, which required states to impose strict security measures on nuclear materials and report on the progress they have made in this regard; many states have not bothered to report — almost all them in Africa; especially worrisome is the situation in Niger, the Democratic Republic of the Congo, Zambia, Malawi, and the Central African Republic

  • Worry: gravitational force would cause nuked asteroids to reform

    The only way to prevent large asteroids from hitting Earth is to use nuclear weapons to blast them to pieces; scientists find that this is not good enough: the gravitational force among the asteroids fragments would cause the asteroid to reform, “Terminator”-like, within hours

  • Pentagon orders accelerated production of 15-ton bunker buster

    The Obama administration is inching toward a dialog with Iran over the latter’s nuclear weapons program, but at the same time it readies the means to destroy Iran’s capabilities should the dialog fail

  • Worries grow about safety of Pakistan's nuclear weapons facilities

    All the terror strikes in Pakistan in the recent past have been suicide attacks, but the attack on the Pakistan Army’s General Headquarters in Rawalpindi three days ago was more of a commando attack carried out by well-trained jihadists; experts worry that such military-style tactics could be used against Pakistani nuclear sites

  • A first: Criminals steal nuclear material, than demand ransom for its return

    Criminals in Argentina steal cesium-137 from a drilling company, then demand $500,000 and threaten “to make this city glow” if they did not get the money

  • Radioactive rabbit poo found at plutonium production site

    A clean-up survey at the Hanford site in Washington State, where military-grade plutonium was produced during the early years of the cold war, discovered radioactive jackrabbit droppings around the site; the rabbits burrowed in the area and discovered the tanks in which nuclear waste is stored; they liked the salty taste of the radioactive cesium and strontium salts, so they began drinking and licking them routinely

  • Revelations about Iran's facility raise questions about U.S. intelligence

    Both the 2003 “slam dunk” assertion about Iraq’s WMDs, and the 2007 NIE’s conclusion that Iran had “halted” its nuclear weapons work, were absurdities; we should worry about the fact that they came to the surface — and influenced policy

  • Missile defense system that might just work

    The Obama administration’s decision to scrap the Bush administration’s plan to place ballistic missile defense systems in Poland and the Czech Republic, and replace it with short-range defensive systems closer to Iran, makes sense; instead of making a political point to Russia, the U.S. might now have in place a defensive system that works

  • Fujitsu asks terrorists whether they would use its software for WMD

    Fujitsu runs a patching site for Sun Microsystems’ Solaris Unix variant; the company asks end-users to fill out a survey before downloading the latest patch, and the first question asks whether the customer would be using the patch to build WMD; even if you admit to building a nuclear bomb, Fujitsu allows you to download the patch; either Fujitsu targets really honest terrorists, or the company wants to use the information in its advertising (as in: “5% of our customers are terrorists who use our software to build weapons of mass destruction”)

  • Understanding nuclear ignition better

    The U.S. nuclear warheads are aging; researchers looking for new ways to figure out safe and reliable ways to estimate their longevity and to understand the physics of thermonuclear reactions in the absence of underground testing currently prohibited under law

  • Pentagon asks Congress for funds for 30,000 bunker-busting bombs

    Intensifying the preparations for an attack on Iran’s nuclear facilities, the Obama administration has asked Congress for funds to accelerate production of a 30,000-pound “ultra-large bunker-buster” bomb designed to destroy deeply buried installations

  • Pakistani jihadists attacked Pakistani nuclear sites three times since 2007

    When Pakistan was developing its nuclear weapons infrastructure in the 1970s and 1980s, its main concern was that India would overrun these nuclear weapons facilities in an armored offensive; Pakistan thus chose to locate much of its nuclear weapons infrastructure to the north and west of the country — but this decision means that most of Pakistan’s nuclear sites are close to or even within areas dominated by Pakistani Taliban militants and home to al-Qaeda
