  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.

  Pencils down: Bids are in to replace the US Army’s Bradley fighting vehicle

  By: Jen Judson WASHINGTON — The bids are in for a chance to build prototypes for the Army's Optionally Manned Fighting Vehicle that will replace its Bradley Infantry Fighting Vehicle. Among them is a Raytheon and Rheinmetall team putting forward Rheinmetall's Lynx 41 Infantry Fighting Vehicle, and General Dynamics Land Systems, which showcased its Griffin III technology demonstrator equipped with a 50mm cannon a year ago at the Association of the U.S. Army's annual exposition. It is currently unknown if any other teams submitted bids by the service's set deadline of Oct. 1. None have come forward publicly despite rumors of a dark horse or two. Absent from the usual brood of combat vehicle manufacturers is BAE Systems. Defense News broke the news earlier this year that the company wouldn't compete in the OMFV competition. Textron has joined the Raytheon and Rheinmetall team with plans to, if chosen to build the new vehicle, build Lynx here in the United States at its Slidell, Louisiana, manufacturing facility. Raytheon and Rheinmetall announced a joint venture Oct. 1 — calling it Raytheon Rheinmetall Land Systems LLC — to pursue the OMFV competition. “General Dynamics Land Systems submitted our OMFV proposal and bid sample to the US Army on 27 September. GD's bid sample was purpose built to address the desired system lethality, survivability and mobility as substantiation of our response to the Army's request for proposal,” the company said in a statement sent to Defense News. The company did not provide details on the submission. GDLS did note, however, that it is proposing a “purpose built vehicle” using technologies from other platforms and “years of investment in advanced capabilities to include a 50mm cannon,” according to the statement. The Army released its request for proposals in March opening a competition to build prototypes. The service plans to choose from the pool of bidders up to two teams to build 14 prototypes each. The service will choose a winner that will start replacing Bradleys in 2026 that is designed to better operate in future environments that would allow soldiers to maneuver to a position of advantage and “to engage in close combat and deliver decisive lethality during the execution of the combined arms maneuver,” according to an Army statement issued along with the RFP release. Some of the threshold requirements for OMFV are a 30mm cannon and a second-generation, forward-looking infrared system, or FLIR. Objective requirements are a 50mm cannon and a third-generation FLIR. Brig. Gen. Ross Coffman, who is in charge of Next-Generation Combat Vehicle (NGCV) modernization efforts, said at the Defense News Conference in September that he is confident the requirements set for OMFV are right and had no plans to change them. The selected prototypes will go through “rigorous” operational testing and soldier assessments. The Army plans to downselect to one vehicle for low-rate initial production following the assessments and testing. https://www.defensenews.com/land/2019/10/01/pencils-down-bids-are-in-for-armys-bradley-fighting-vehicle-replacement
