DARPA: Discover DSO Day Announced
DARPA's Defense Sciences Office (DSO) will host Discover DSO Day (D3) on June 18, 2019, to facilitate discussion of technical research thrusts outlined in a new office-wide Broad Agency Announcement (BAA) solicitation expected in mid-June. Additionally, D3 will familiarize participants with DSO's mission and streamlined business practices designed to simplify the proposal process and accelerate the timeline from idea approval to research start date. The event will take place in the DARPA Conference Center, Arlington, Virginia, from 8:45 a.m. to 5:00 p.m. EDT, and the audio also will be webcast. Registration is required to attend in person or via webcast.
One of six technical offices at DARPA, DSO identifies and pursues high-risk, high-payoff research initiatives across a broad spectrum of science and engineering disciplines and transforms them into game-changing technologies for U.S. national security.
“D3 is an opportunity for the broader science and technology community to engage with DSO as we highlight key technical areas we're focusing on in the coming year,” said Valerie Browning, director of DSO. “We encourage potential proposers from small companies, universities, research centers and large companies to join us. We especially encourage those who've never done business with DARPA to come and learn about DSO and let us hear your novel ideas in the areas we're interested in.”
Panels of DSO program managers will discuss concepts and ideas they are pursuing in each of the four technical areas listed below. Participants will have the opportunity to ask questions following each panel presentation:
Frontiers in Math, Computation & Design: The increasingly complex, technologically sophisticated, fast-paced and dynamic military operational environment imposes fundamental challenges in how we design and plan for future military needs. The DoD implications of these trends drive a need for new math, computation, and design tools that enable trusted decision making at increased speed and with known confidence levels. Topics of interest under this domain include, but are not limited to, the following: (1) mathematical, computational, and design frameworks and tools that provide robust solutions to challenging DoD problems such as planning, optimization, and platform design; (2) fundamental scientific underpinnings and limits of machine learning (ML) and artificial intelligence (AI); and (3) alternative computing models, architectures, and substrates for faster, more robust decision making.
Limits of Sensing & Sensors: Sensing and measurement of signals ranging from “DC to daylight” are ubiquitous to military systems and missions. Surveillance, navigation, warfighter health monitoring, and target ID/tracking are just a few examples of missions and/or applications that rely on various sensing modalities. Topics of interest under this domain include, but are not limited to, the following: (1) new sensing modalities, (2) fundamental sensing limits, (3) engineered materials that enable novel optics and imaging capabilities, (4) fundamental and practical limits of quantum enabled sensing and metrology, and (5) practical and deployable sensing and sensor designs.
Complex Social Systems: Understanding social behavior and the dynamics of complex social networks is critically important for many military operations including stability, deterrence, compellence, counter-terrorism, shaping the environment, training, and mission planning. Additionally, increasingly robust machine capabilities in the form of automation, platforms, and artificial intelligence (AI) will fundamentally change how human teams frame problems, plan, and operate at tempo and manage complexity. Topics of interest under this domain include, but are not limited to, the following: (1) accurate and scientifically validated models of the social dynamics underlying different kinds of conflict; (2) capabilities to improve understanding of causality in complex social systems; (3) artificial intelligence and other tools that enable improved human-machine symbiotic decision-making; and (4) new concepts in war-gaming and simulations to identify and understand options for deterrence and stability operations.
Anticipating Surprise: Ultimately, the goal of DSO R&D investments is to ensure that U.S. warfighters have access to the most advanced technologies. Research funded under this thrust area supports scientific and technological discovery that leads to “leap ahead” capabilities for enhanced military readiness across multiple operational domains. Example topics of interest under this domain include, but are not limited to, the following: (1) novel functional and structural materials and manufacturing processes; (2) materials for harsh environments; (3) defense against Weapons of Mass Destruction/Weapons of Mass Terror (WMD/WMT) threats; (4) energetic materials; (5) new propulsion concepts; and (6) novel approaches to energy storage and power generation.

The US Air Force wants to develop a hypersonic cruise missile
By: Valerie Insinna WASHINGTON — The U.S. Air Force is seeking information from industry about hypersonic cruise missile technology, with the hopes of starting up a new prototyping program in the near future. The service issued a sources sought notification on April 27 asking companies to submit information about air-breathing conventional hypersonic cruise missiles that could be launched from fighter jets and bombers. The responses will help the Air Force determine whether to begin funding a new program of record and figure out how quickly it will be able to field the new weapon, said Air Force acquisition executive Will Roper. “In the case of how fast we could go with the scramjet technology getting into cruise missile and missionizing it, I think we can go fast,” he told reporters April 30. “I don't know how fast — that's why we're reaching out to the street. But given how far scramjet technology has matured, I'd expect that we'll be able to go pretty quickly on this.” According to the solicitation, the service would aim to conduct a preliminary design review in the fourth quarter of fiscal 2021. The technologies offered should feature ramjet, scramjet or dual-mode propulsion — a major difference from the hypersonic weapons currently under development by the Defense Department, which are all boost glide missiles. There are multiple advantages to fielding air-breathing and boost glide hypersonic weapons, Roper said. Boost glide missiles fly just below space, above the “thick atmosphere” where scramjet missiles would fly. That allows scramjet missiles to take on certain missions and targets that boost-glide systems cannot engage. “In the world of competing technology, we can't afford to have any blind spots or cede any ground. So we're preparing to make sure we don't cede ground on scramjet technology and hypersonic cruise missiles as a whole,” Roper said. “We will have greater flexibility with this as a whole. That's one reason we're interested in accelerating the technology. It's mature, it's ready. It will give our operators greater flexibility.” It will also allow the Defense Department to diversify the number of companies that can produce hypersonic weapons, he said. “In the case of boost glide technology, a lot of our major programs in the department go to the same suppliers,” in part because those companies have pioneered materials and components that have not been replicated throughout industry, Roper said. “One of the reasons I'm excited about starting a hypersonic cruise missile program is that we will have different suppliers. It's a very different technology.” Roper said the hypersonic cruise missile effort would involve inputs from the Air Force Research Laboratory and the Defense Advanced Research Projects Agency. In particular, DARPA's Hypersonic Air-breathing Weapon Concept, or HAWC, effort could inform the new program. As part of the effort, a Raytheon-Northrop Grumman team and a Lockheed Martin-Aerojet Rocketdyne team are building scramjet-powered hypersonic vehicles. “Scramjet technology has come a long way. I have been exceptionally impressed by what new manufacturing techniques are enabling,” Roper said. “I entered this job thinking scramjet will probably be a step behind boost glide. I am delighted to say that I was wrong. Scramjet is much more mature and ready to go than I originally thought.” The Air Force may be embarking on a new hypersonic weapons program just months after canceling one of its two development efforts, the Hypersonic Conventional Strike Weapon, or HCSW. Although HCSW showed promise and was on track for flight tests, the service killed it the fiscal 2021 budget rollout this February in favor of the Air-Launched Rapid Response Weapon. Both ARRW and HCSW are boost-glide weapons made by Lockheed, but the Air Force decided to pursue ARRW because it was more affordable and could be carried in larger quantities by the B-52 and F-15 aircraft, Roper said. https://www.defensenews.com/industry/techwatch/2020/04/30/the-air-force-wants-to-develop-a-hypersonic-cruise-missile/

Aviation Week Forecasts: Western C4ISR Commercial Airliner Aircraft MRO 2020-2029
June 23, 2020 Aviation Week Network forecasts that from 2020 to 2029, Western-built commercial airliners performing military C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance) missions will generate $20.7 billion in maintenance, repair and overhaul (MRO) demand, declining 4% over the decade. These figures only include aircraft categorized as commercial airliners that are specifically equipped to perform C4ISR missions against land and airborne targets—everything from aircraft equipped with just electro-optic/infrared (EO/IR) devices to sophisticated electronic warfare platforms. Excluded are observation aircraft not specially equipped for C4ISR missions, any dedicated search-and-rescue aircraft, and military VIP transports. The single largest source of MRO demand over the forecast is the Boeing 707, which will produce a dominant 78.6% of the global forecast total. The 707 is the base airframe for 13 different C4ISR platforms around the globe, including the U.S.'s E-3, E-6, and E-8 fleets. Despite the dominance, the 707's annual demand will decline 14.5% in the next 10 years. Boeing's queen of the skies, the 747, will produce the second most MRO demand this decade, albeit a 10th of the 707. The 747 takes the lead in terms of MRO decline, shedding 33.5% of its demand by 2029 as the U.S. Air Force is expected to retire some of its smallest but most expensive-to-maintain fleets like the E-4. There is an estimated $330 million in MRO demand for yet-undecided military competitions and requirements that are assessed to be won by a commercial airliner C4ISR platform. While only 1.6% of the forecast total, it is 7.1% of the total in 2029, making it the second-largest source of MRO that year. https://aviationweek.com/defense-space/z/aviation-week-forecasts-western-c4isr-commercial-airliner-aircraft-mro-2020-2029
