SPACE & MISSILE DEFENSE SYMPOSIUM, HUNTSVILLE, ALA.: Imagine a technology that could detect roadside bombs and landmines buried underground, pick out a nuclear warhead from a cloud of decoys miles away, or even fry enemy electronics, potentially disarming those warheads from a distance. Well, physicist William Dent has invented that technology and briefed its potential to the Army and industry here. It's called a neutron beam generator.
Dent's idea is a potential breakthrough for bomb squads and missile defenses, enthused conference organizer David Mann, a three-star Army general who ran Space & Missile Defense Command here (SMDC) until his retirement in 2016. Despite the Star Trek-esque name, Mann told me after Dent's presentation, this is a feasible real-world technology, a matter of “when, not if.”
Dent is already working with the Army to explore the low-hanging fruit: detecting buried explosives at a distance. Now, the military already uses neutron generators for this, because neutrons easily penetrate most materials (they have no electric charge to interact with and a lot of mass to give them momentum) but will stop and generate a distinctive burst of gamma rays when they hit high-density materials like explosives. The problem with current systems is their range is very short, anywhere from one meter to 20-plus depending on the size of the explosive and the depth to which it's buried.
Why? Traditional neutron generators shoot off neutrons indiscriminately in all directions, the same way a light bulb emits light. That means the neutrons spread out rapidly, in fact exponentially (specifically, divide strength at the source by the square of the distance). Very soon, there are too few of them hitting any particular target to trigger enough gamma radiation to detect.

Yet industry executives believe foreign arms sales will remain a priority of the new administration. BY MARCUS WEISGERBER GLOBAL BUSINESS EDITOR JANUARY 26, 2021 02:51 PM ET Raytheon Technologies executives told investors Tuesday that it expects the Biden administration to block at least one arms deal to a Middle Eastern ally as the U.S. shifts its weapons export policy. Raytheon CEO Greg Hayes, speaking on the company's quarterly earnings call, said Raytheon has removed from its books a $519 million projected sale of an “offensive weapon system” to a “customer in the Middle East...we can't talk about.” On the same call, CFO Toby O'Brien said the sale involves an “offensive munition.” The scale of the deal indicates that the execs were referring to the planned sale of some 7,500 Paveway bombs to Saudi Arabia. Last April, Raytheon said in a regulatory filing that its arms sales could be hurt by lawmakers' concerns about Riyadh's role in Yemen's civil war and about the Saudi crown prince's involvement in the murder of a U.S.-based Saudi journalist. Still, in December, Bloomberg reported that the Trump administration was moving ahead with the sale. “We had assumed that we were going to get a license to provide these offensive weapon systems to our customer,” Hayes said. “With the change in administration, it becomes less likely that we're going to be able to get a license for this. And so we appropriately decided that we could no longer support the booking of that contract.” During his Senate confirmation hearing last week, now-confirmed Secretary of State Anthony Blinken said the Biden administration would “end our support for the military campaign led by Saudi Arabia in Yemen.” Still, Hayes said the company does not anticipate issues selling defensive weapons, like Patriot missile interceptors, and other types of arms in the region. “Look...peace is not going to break out in the Middle East anytime soon,” Hayes said. “I think it remains an area where we'll continue to see solid growth.” Similarly, Lockheed Martin CEO Jim Taiclet expected foreign arms sales to remain a priority in the Biden administration. “As far as international business, including foreign military sales, the tendency of the people in the Biden administration [and] in the president's own statements, reiterate his view that alliances are important that they need to be cultivated, and that they have real value in deterrence and national defense,” Taiclet said. “I do think that we'll have a more open environment for [foreign military sales] and direct commercial sales to our international partners.” Taiclet said foreign weapon sales are a way to generate American jobs and stimulate the U.S. economy. “If jobs and the economy are important, the promotion of international defense sales, one would surmise, would also be important,” Taiclet said Tuesday morning on Lockheed's quarterly earnings call. While arms sales create jobs growth, a 2019 Center for International Policy report said those claims, particularly during the Trump administration, were greatly exaggerated. Still Taiclet, a former U.S. Air Force pilot, said arms sales are a way to deepen relationships with an ally. “I can tell you that there's no better way to get a tighter bond with an ally than sell them jet fighter aircraft,” he said. “All the way back in the mid-[19]80s, when I was in pilot training, we had Saudis in our class, for example.” https://www.defenseone.com/business/2021/01/raytheon-expects-biden-block-500m-bomb-sale-saudi-arabia/171645/
