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.

Pandemic not slowing Army plans to field enduring indirect fires protection capability
By: Jen Judson WASHINGTON — The COVID-19 pandemic is not slowing down the Army's plans to field an enduring indirect fires protection capability, according to Lt. Col. Juan Santiago, the service's program development manager for the effort. The Army has had to take a few steps back over recent years to reconsider its ways forward to develop an enduring capability to defend against rockets, artillery and mortars as well as cruise missiles and unmanned aircraft systems. As the service re-examined its path, Congress mandated that it buy an interim capability aimed directly at protecting the force from a growing cruise missile threat, but the Army has stressed that the system it will use — Rafael's Iron Dome — won't cover all the bases needed for a lasting capability. Earlier this year, the Army sent a report to Congress outlining its plans to get after the enduring capability, partly by hosting a shoot-off with vendors that bring launcher and interceptor capabilities next year. The Army issued a request for information to industry at the beginning of March with plans to conduct an industry day. But with the COVID-19 pandemic raging in the United States and limiting travel and social contact, the IFPC program office had to get creative in order to keep the program moving forward. The office was able to host one-on-one meetings with interested vendors as part of an industry day this month and is planning to answer industry questions, which have been submitted virtually, Santiago told Defense News in an April 9 interview. To stay on track with the program, the office couldn't afford to delay industry engagements in order to keep the ball moving, Santiago explained. The next big step for industry is to submit white papers to the Army toward the end of April, Santiago said. The Army will review the papers over the course of a month and will notify industry by the end of May whether or not they will be invited to proceed into an agreement with the service to move forward, he said. Those selected will move into a modeling and simulation phase that will also include some hardware-in-the-loop activities where capabilities are demonstrated in a simulated environment to determine if they are ready to go out on the range for the live shoot-off next year in the 3rd quarter of fiscal 2021 at White Sands Missile Range, New Mexico. Santiago said he could not disclose the number of agreements that might be awarded. The Army will invite vendors to submit final proposals following the shoot-off, Santiago said, but even if a vendor isn't ready for that phase, it can still submit a final proposal that draws upon performance in a simulated environment and includes a plan to get to a live-fire capability within the desired timeline. The government will evaluate final proposals and choose one vendor to provide the launcher and interceptor solution in the fourth quarter of FY21, Santiago said. Initial capabilities are expected to be fielded by FY23. https://www.defensenews.com/land/2020/04/10/pandemic-not-slowing-down-army-plans-to-field-enduring-indirect-fires-protection-capability/

With China looming, intelligence community backs AI research
By: Justin Lynch The U.S. government wants to boost its artificial intelligence capabilities or risks being left behind by the private sector and China. In the last two years, that's meant new AI initiatives from the Pentagon, the Defense Advanced Research Projects Agency and the intelligence community. Now, the Intelligence Advanced Research Projects Activity is requesting information about research efforts on “cutting-edge machine learning techniques.” IARPA posted the formal request for information Dec. 4. The deadline for industry to submit information is Jan. 17. “Of specific interest is the respondent's knowledge of, and experience implementing, current, cutting-edge machine learning techniques,” the intelligence community's research arm said. Respondents are required to have top secret clearances to work on the project, according to the IARPA listing. In addition to its deep learning program, IARPA leaders want information about research into “future computing systems” that can self-learn. Such a move could have implications for improving government cybersecurity. “The need for real-time (or near-real-time) analysis of massive amounts of heterogeneous data in this new era of explosive data growth has dramatically broadened the application space for advanced computers,” IARPA said. “The current volume and variety of data are already beginning to exceed the ability of today's most advanced classical systems to deliver optimal solutions.” Most cyber threat detection platforms use some form of artificial intelligence to create warning indicators, according to public and private sector officials. However, the U.S. government is behind the private sector when it comes to use of AI, said James Yeager, the public sector vice president at cybersecurity firm Crowdstrike. “There is, by design, a more staggered type of approach to some of these advances in technology in the public sector, and as a result, the government is going to be behind the private sector,” Yeager said. IARPA has a “very high-risk-but-high-reward approach to solving complex problems. They take a lot of time and take a lot of resources,” said Yeager. “But If they can come out of that research project with a silver bullet, it is going to benefit everyone.” Andrew Laskow, a senior manager at Blue Prism, which provides AI products to federal government and defense agencies, said that in the U.S. government many people are “looking to AI for problems that they cannot solve.” “There is still a misunderstanding at the highest levels of what AI can and cannot do,” Laskow said. Public and private sector officials warn that AI-backed threat network indicators can overload users and create too many warnings. Michael McGeehan, head of business development at Blue Prism, described intelligent automation being broken down into the “thinking side” and the “execution side.” The artificial intelligence platform is the “thinking side” that makes decisions and is analogous to the human brain. On the other hand, robotic processing automation is the “execution side” that carries out tasks, like an arm or a leg. https://www.fifthdomain.com/dod/2019/01/12/with-china-looming-intelligence-community-backs-ai-research
