  DARPA Announces Microsystems Exploration Program

  Over the past few decades, DARPA's Microsystems Technology Office (MTO) has enabled revolutionary advances in electronics materials, devices, and systems, which have provided the United States with unique defense and economic advantages. To continue its path of successful electronics innovation, DARPA today announced a new MTO effort called the Microsystems Exploration program. The Microsystems Exploration program will constitute a series of short-term investments into high-risk, high-reward research focused on technical domains relevant to MTO. Leveraging streamlined contracting and funding approaches, awards for each area of exploration – or μE topic – will be made within 90 days of announcement. Each μE topic will run for up to 18 months, during which time researchers will work to establish the feasibility of new concepts or technologies. “This strategy of making smaller, targeted research investments will allow us to capitalize quickly on new opportunities and innovative research concepts,” said Dr. Mark Rosker, director of MTO. “The Microsystems Exploration program provides a way to assess whether or not a concept could evolve into a full program without requiring the use of more significant resources.” The Microsystems Exploration program will employ best practices from DARPA's other fast-track solicitation programs – the agency-wide AI Exploration program and the Defense Science Office's “Disruptioneering” initiative. These programs are focused on enabling rapid advances in artificial intelligence and basic science respectively, and have shown numerous benefits to this approach. Similar to these efforts, the simplified proposal, contracting, and funding process employed by each μE topic will make it even easier for individuals and organizations to contribute to DARPA's mission. Each award may be worth up to $1 million, as described in the individual μE solicitations. To help advance MTO's strategic imperatives, the Microsystems Exploration program will pursue innovative research concepts that explore frontiers in embedded microsystem intelligence and localized processing; novel electromagnetic components and technologies; microsystem integration for functional density and security; and disruptive microsystem applications in C4ISR, electronic warfare, and directed energy. In alignment with these technical domains, the first three potential topics focus on hardware security, novel materials, and new computing architectures for heterogeneous systems. The first potential topic aims to address security issues within the hardware supply chain. Defense systems increasingly rely on commercial of the shelf (COTS) devices that move through complex supply chains, with each component changing hands several times. Throughout the process, nefarious actors have numerous opportunities to compromise the technology by introducing malicious circuitry – or hardware Trojans – to printed circuit boards (PCBs). The ability to detect when components are tampered with is difficult as the attacks are designed to remain hidden and avoid post-manufacturing tests until its functionality is triggered. The “Board-Level Hardware Security” related topic could explore the technological feasibility for real-time detection against these hardware Trojans installed in complex COTS circuit boards. New uses of scandium (Sc)-doped aluminium nitride (AIN) could be investigated as a future potential μE topic. Sc-doped AlN is a popular material for a number of device applications, which span RF filters, ultrasonic sensors, and oscillators. Recent work has demonstrated the emergence of the material's use in ferroelectric switching, which has enormous potential across a number of applications and devices. However, current exploration of this capability has been limited to a research setting. The “Ferroelectric Nitride Materials and Non-Volatile Memory” related topic could expand on this research, identifying the thickness and doping ranges that exhibit ferroelectric behavior, the robustness and reproducibility of the ferroelectric response, and further demonstrating ferroelectric nitrides as a technologically useful material. Another potential μE topic could seek to address the trade-off between programmer productivity and performance that happens as hardware complexity continues to skyrocket. Advances at the hardware and software level that have enabled continued progress in computing performance, cost, and ubiquity have hit a wall. The expectation is that subsequent performance gains will come from an increased level of parallelism, specialization, and system heterogeneity, which will place further strain on programmer productivity. This “Massively Parallel Heterogeneous Computing” related topic could explore the creation of compiler technology that improves programmer productivity of massively parallel and heterogeneous processing systems. Additional information about the Microsystems Exploration program can be found under Program Announcement DARPA-PA-19-04. Further details on the three potential μE topics can be found under Special Notice DARPA-SN-19-69. The Microsystems Exploration Research Area Announcement Special Notice has been issued solely for information and potential new program planning purposes. All future and official solicitation notices for μE topics will be published to Federal Business Opportunities (FBO) at www.fbo.gov. https://www.darpa.mil/news-events/2019-07-16

  The US Navy’s new autonomous refueling drone takes historic first flight

  By: David B. Larter WASHINGTON — The U.S. Navy's MQ-25 Stingray refueling drone, destined to be the first carrier-launched autonomous unmanned aircraft integrated into the service's strike arm, took its first test flight from MidAmerica Airport in Illinois, Boeing announced Thursday. The two-hour flight, remotely controlled by Boeing pilots, tested the basic flight functions of the aircraft, a Boeing statement said. “The aircraft completed an autonomous taxi and takeoff and then flew a pre-determined route to validate the aircraft's basic flight functions and operations with the ground control station,” the release said. Boeing's project head said it was an important step toward getting the drone on the flight deck. “Seeing MQ-25 in the sky is a testament to our Boeing and Navy team working the technology, systems and processes that are helping get MQ-25 to the carrier,” MQ-25 Program Director Dave Bujold said in the release. “This aircraft and its flight test program ensures we're delivering the MQ-25 to the carrier fleet with the safety, reliability and capability the U.S. Navy needs to conduct its vital mission.” An $805 million contract awarded to Boeing last August covers the design, development, fabrication, test and delivery of four Stingray aircraft, a program the service expects will cost about $13 billion overall for 72 aircraft, said Navy acquisition boss James Geurts. The award to Boeing kicks off what the Navy would is aiming to be a six-year development effort moving toward a 2024 declaration of initial operational capability. At the end, it will mark a historic integration of drones into the Navy's carrier air wing. The MQ-25 flown Thursday is a Boeing-owned test asset and a predecessor to the first four engineering design model aircraft provided for under last year's contract. The model “is being used for early learning and discovery to meet the goals of the U.S. Navy's accelerated acquisition program,” the release said. The Stingray was a priority pushed by the Navy's previous chief of naval operations, Adm. John Richardson, who saw it as a chance to force a program through the system and field a new capability quickly. “The MQ-25 was really a signature program to test the limits and plow new ground in that direction,” Richardson told Defense News last April. "And so we brought industry in way earlier. I think that's key to getting the acquisition cycle faster, even in the refinement of the requirements phase. “And so that's where we've been with MQ-25, is to bring them in, see what they've got and see how fast they can get a prototype together to fly. One thing we did do was we locked down on requirements. We could probably get agreement from everybody that we need something to tank. It liberates a lot of our strike fighters from doing that mission and it's something that we can get done ― its relatively straightforward.” https://www.defensenews.com/naval/2019/09/19/the-us-navys-new-autonomous-refueling-drone-takes-historic-first-flight
