Detect Nukes In Flight With Electron Beam Technology
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.

Australia releases RFI for at least 16 special operations helicopters
By: Nigel Pittaway MELBOURNE, Australia — Australia's Defence Capability Acquisition and Sustainment Group issued a request for information for at least 16 special operations support helicopters. The helicopters will be acquired under Project Land 2097 Phase 4, which has not been formally approved by the Australian government but has been identified as a priority for future defense spending in the 2016 Defence White Paper. The proposed timeline calls for a request for tender in the fourth quarter of 2019, with the major delivery of equipment to follow in 2022. “The project is currently in the exploratory phase, collecting information and proposals to inform concepts for capability realisation,” according to the RFI's cover letter, authored by CASG's acting first assistant secretary of the helicopter division, Brigadier Jeremy King, and the head of land capability at Army Headquarters, Maj. Gen. Kath Toohey. “The project is considering a wide range of procurement options based around a light helicopter as the major system. The acquisition strategy is developmental and is subject to Government approval,” the letter read. According to the RFI, the requirement is for a proven commercial or military off-the-shelf light helicopter, which is already in service with other operators. Other requirements include optimization for use in dense urban environments, capable of rapid deployment by the Royal Australian Air Force's C-17A airlifters, and the ability to be fitted with simple and proven intelligence, surveillance and reconnaissance equipment and weapons. The helicopters are intended for use by the Australian Army's 6th Aviation Regiment, based at Holsworthy, south of Sydney, and will complement a squadron of larger NHI MRH-90 Taipan helicopters. The Taipans are replacing the 6th Aviation Regiment's existing Sikorsky S-70A-9 Black Hawk, beginning in January 2019. The RFI does not specify a desired size for the new helicopter, but four are required to be deployed aboard one C-17A. In an earlier update to the Army's major battlefield aviation programs, CASG's first assistant secretary of the helicopter systems division, Shane Fairweather, and Toohey discussed a helicopter in the four-ton class. The primary role of the new helicopter will be to provide an air assault capability by small teams of special forces, with secondary roles including ISR (using electro-optical sensors), fire support and general utility. The RFI calls for a helicopter that can be rapidly reconfigured between these roles. The main base for operations will be at Holsworthy, but the Australian Army is considering the establishment of a permanent detachment of helicopters — referred to in the RFI as the “independent detachment” — in a yet-to-be-decided location. Australia's Special Operations Command has two commando regiments based at Holsworthy and the Special Air Service Regiment based in Western Australia. The RFI calls for four helicopters to be maintained online at Holsworthy, in addition to the independent detachment (four aircraft) and two deployable elements, each of four helicopters. The number of helicopters to be acquired is not specified in the document, but respondents are asked to provide an assessment of how many will be needed to support 16 aircraft online at any given time. The forthcoming RFI was a major focus at the 2018 Land Forces exhibition, held in Adelaide in early September, with several major helicopter manufacturers declaring their intention to respond. Then-head of Airbus Group Australia Pacific Tony Fraser said the European manufacturer intends to offer its 3- to 7-ton H145M helicopter. “We will compete the H145M and we expect it to be a very strong competitor,” he said. Also speaking at Land Forces, Bell's business development director for Australia, Dan McQuestin, revealed that the company intends to bid the 2.5-ton Bell 407GT, an armed version of the popular 407GX civil helicopter. “It's COTS, it's already deployed in the field in the Middle East and maintained through a commercial supply chain,” he said. Boeing Defence & Security's vice president of global sales and marketing for Australia said he was keen to see what the Commonwealth's requirements would be, but the U.S. manufacturer saw its 1.6-ton AH-6i Little Bird as a candidate. “Based on our conversations, we think the AH-6i is a viable alternative for Land 2097 Phase 4,” he said. “We'll see what is in the RFI, but we certainly expect to bid.” Leonardo's helicopter division announced during the show that it will propose the AW109 Trekker helicopter. Other potential contenders include MD Helicopters with its MD530G helicopter, and Northstar Aviation with the 407MRH Lightning, a multirole helo based on the Bell 407. https://www.defensenews.com/industry/2018/10/02/australia-releases-rfi-for-at-least-16-special-operations-helicopters

BAE nabs next-gen seeker design work for US Army’s missile defense system
By: Jen Judson WASHINGTON — Lockheed Martin, which builds the Terminal High Altitude Area Defense weapon system for the U.S. Army, has awarded BAE Systems a contract to design and manufacture a next-generation seeker for the system's interceptors, according to a BAE announcement posted March 17. “The sensor design work will improve the missile defense system's ability to neutralize more threats and improve its manufacturability,” the statement read. The company did not disclose the contract amount or timelines to develop a design. The THAAD weapon system is part of the Army's layered approach to missile defense, now with its ability to defeat ballistic missile threats in the terminal phase of flight, but the Missile Defense Agency also wants to make it part of its future homeland defense architecture. BAE already provides the seeker for the THAAD system, which uses infrared imagery to guide the interceptors to threat targets, and the company has delivered more than 500 THAAD seekers to date, according to the statement. While the seekers are built in Nashua, New Hampshire, and Endicott, New York, the company plans to conduct design work for the next-generation seeker in Huntsville, Alabama, home of Redstone Arsenal and the Army's missiles and space programs. BAE Systems is building a state-of-the-art facility that will house a “cutting-edge” design program in Huntsville, the company noted. While the Army plans to continue using THAAD far into the future, the MDA is, in fiscal 2021, planning to allocated $273.6 million for THAAD development efforts, including the THAAD homeland defense tier. Specifically, the agency is asking for $139 million in FY21 to start the development and demonstration of a new interceptor prototype for THAAD, which could support a tiered and layered approach to homeland defense. BAE Systems did not say whether the next-generation interceptor design work includes efforts related to MDA's desire to produce a new interceptor prototype. The agency is “challenging ourselves” to figure out how to develop a THAAD interceptor that would work against an intercontinental ballistic missile, Vice Adm. Jon Hill, the MDA's director, said when the FY21 defense budget request was released in February. To do that, the MDA is seeking to draw lessons from building THAAD batteries for Saudi Arabia, he said. The agency is also looking at the existing engineering trade space. “We may consider an upgraded propulsion stack to give [THAAD] extended range, don't know yet,” he said. “It could be that we don't want to update the propulsion. Maybe there is something in the seeker that would buy us more in the trade space now.” The THAAD interceptor program is a new start in the FY21 budget request, Hill noted. “We are working our way through what that program would look like.” https://www.defensenews.com/smr/army-modernization/2020/03/17/bae-nabs-next-gen-seeker-design-work-for-us-army-missile-defense-system/
