    US Army seeks to compete as OMFV prime, industry unnerved

    by Ashley Roque Industry is concerned about a potential US Army plan to bid on, judge, and select its own M2 Bradley Fighting Vehicle replacement, and is likening such a measure to a metaphorical self-licking ice cream cone. During the past few weeks, defence companies have been eagerly awaiting the release of a draft request for proposal (RFP) for the army's latest attempt to design and field an Optionally Manned Fighting Vehicle (OMFV). Although they were interested in learning more about what the army is seeking this time around, they were also keen to see if a provision was included that enabled the service's Ground Vehicle Systems Center (GVSC) to also compete as a prime contractor. As several sources suspected, the draft RFP publicly released on 17 July included such provision. “Potential offerors are notified that a US government entity may submit a proposal as a prime offeror,” the army wrote. Ashley John, the public affairs director for the army's Program Executive Office for Ground Combat Systems, confirmed to Janes on 19 July that the service is exploring options to “leverage its core competencies and compete with industry in the design of a future combat vehicle”. More specifically, she said that the service wanted to use its science and technology community and engineers to “potentially develop” a Bradley replacement vehicle. As a result, interested vendors now have a flurry of questions over the ethics and legality of such a measure.

    Detect Nukes In Flight With Electron Beam Technology

    SYDNEY J. FREEDBERG JR. So, I asked, could a sufficiently high-powered neutron beam not just detect a nuclear warhead from a distance, but actually disable it? Dent, who worked on the Safeguard missile defense system as a young Army officer and later on Reagan's Star Wars initiative for SAIC, pondered a moment. Then he said: “Could it fry the electronics ? Yes, it could." 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.
