    eBrief: Drones An “Immediate Threat” – DoD Plans Rapid Acquisition of Counter-UAS Systems

    By BARRY ROSENBERGon March 17, 2020 at 12:53 PM The urgency to protect troops, bases, and installations from drone attacks changed forever last year when a swarm of small, low-flying drones unleashed by Yemen's Iranian-backed Houthi rebels targeted Saudi Arabian oil processing facilities. The attack was nothing less than a Pearl Harbor-type wake-up call for the need to counter unmanned aerial systems with defense technology commonly referred to as C-UAS. This Breaking Defense E-Brief examines U.S. Defense Department and global efforts to stay ahead of the threat. It examines sensor development to detect UAS, the use of artificial intelligence to identify targets, and defeat mechanisms ranging from jamming to lasers to knock them down. https://breakingdefense.com/2020/03/ebrief-drones-an-immediate-threat-dod-plans-rapid-acquisition-of-counter-uas-systems

    The US needs to rethink its overseas supply chain

    By: Thomas Ayres As Americans respond to the COVID-19 pandemic, we have become acutely aware of the outsized impact of our dependence on China in the supply chain. Pharmaceutical companies learned key chemicals and minerals are exclusively made or mined in China. For instance, reports show China produces 97 percent of the antibiotics, 95 percent of ibuprofen and 91 percent of hydrocortisone consumed in the U.S. market. Hospitals also learned that while China produces 50 percent of the world's face masks, they are of dubious reliability. There is cause for concern with the quantity or quality of ventilators. In sum, we learned as citizens what we in the Department of Defense have known for some time: Our national security supply chain must be free from dependence on China. The DoD's concern for its supply chain is not new. Congress spurred activity over a decade ago by questioning the DoD's supply chain risk management, or SCRM, policies. The National Defense Strategy‘s recognition of a new era of strategic, great power competition further sharpened the DoD's focus, propelling recent efforts to enhance regulations and procedures in addressing supply chain threats. We are transitioning from analog to digital, with the goal of planes, ships, tanks and satellites all seamlessly sharing data — a lethal version of the ride-sharing app on your smartphone. Yet, even as the DoD builds this future, the threat of supply chain disruption and concerns about component quality within the electronic backbone are real. Counterfeit or planted microelectronic parts can be vectors for cybersecurity intrusions. Recently, for instance, the DoD voiced concerns that Chinese telecommunications giant Huawei's 5G solution provided back doors, purposefully or negligently, for data corruption, data extraction, system failure or worse. Similarly, SCRM policies have increasingly addressed the concern of intellectual property theft enabled by subcomponents designed to allow information to flow back to larger architectures. The COVID-19 pandemic is giving new meaning to that threat, and the risk of disruption to both raw and manufactured materials from abroad has become apparent. Our SCRM focus must broaden in response to COVID-19 to better address national production capacity and sustainability. Being able to assure access to the minerals, chemicals, subcomponents and components required to build weapon systems is essential. China supplies 80 percent of the rare earth minerals imported to the U.S., many of which are essential to electronic parts. Since 1933, the Buy American Act has required federal agencies, including the DoD, to purchase items manufactured in the U.S. Additionally, these items must be made from supplies mined or made in the U.S. The act is implemented by regulations requiring analysis of the components — where they are mined or made, and where they are assembled. Companies that falsify “Made in America” designations can be debarred from the federal marketplace. In July 2019, months before the pandemic emerged, President Donald Trump issued an executive order seeking to increase the minimum domestic manufacture thresholds above the current 50 percent floors. The pandemic now shows even more needs to be done. We must increase to President Trump's mandated percentages, and we must also analyze where each of the subcomponents are manufactured. This doesn't mean we need to back away from allied contributions or alliance-based weapon systems like the F-35 fighter jet, which benefits from the industrial cooperation of nine partner nations. But in light of COVID-19, it does mean that when we make risk-based and measured decisions to produce an alliance system, we program in several months' worth of component backlogs to allow continued production during future quarantines. The majority of our weapon systems are made in the U.S. by American companies with greater than 50 percent of component production and assembly done domestically. Yet, what is less clear are the composition of the subcomponents in the components themselves. Not recognizing the risks of the subcomponents equally jeopardizes the new reality of disruptions to our supply chain and risks of data extraction, degradation and spying, about which we have increasingly been concerned. Recently, I sought to buy a grapefruit spoon on the internet and found it exceedingly difficult to learn where the offered spoons were made. The harder it was to find, the more I suspected it was made in China. Perhaps Congress should pass a law making it easier to learn the source of manufacturing. Ensuring my access to an American-made grapefruit spoon is not nearly as vital as assuring our access to critical weapon systems, rare earth materials, and pharmaceuticals and medical supplies. A vital step is knowing the source countries of components and subcomponents. We must have deeper knowledge of the full supply chains of subcomponents, and how and where they are produced. Trust can only come once we know all that is required to understand our supply chains and we seek even greater focus in our new normal. Our security depends on it.

  • Bell Invictus to Offer Army ‘Lower-Risk Path’ to FARA Capabilities

    Bell Invictus to Offer Army ‘Lower-Risk Path’ to FARA Capabilities

    By Brian Garrett-Glaser ARLINGTON, Texas — Bell's offering for the Army's Future Attack Reconnaissance Aircraft (FARA) contest, the 360 Invictus, is intended to offer the Army an insurance policy by presenting a lower-risk path to the capabilities it hopes to acquire as a “knife fighter” light attack helicopter to replace the retired OH-58 Kiowa Warriors. The Invictus, with its low-drag tandem cockpit design, draws from a lot of the development Bell has put into the 525 Relentless, a super-medium utility aircraft it hopes will be the first fly-by-wire rotorcraft certified for the civil market. Though Bell's FARA program is newer than some of its competitors, such as Sikorsky's S-97 Raider — Bell officials said the program had just three employees at this time last year and now comprises over 200 — the company believes its reliance on systems which it already has at a high technology readiness level due to work on the 525 will provide the Army with a compelling aircraft inside of its cost and timeline objectives. “It's still a very advanced aircraft. But by using technologies that we already had high TRLs in, or high manufacturing readiness levels in, we are ahead on that timeline piece,” Frank Lazzara, director of advanced vertical lift systems, told Avionics International during a press visit to the company's Flight Research Center here. The Invictus design meets or exceeds Army requirements in every area, according to Lazzara, due in part to the clean-sheet engineering that went into the Bell 525, including in the main and tail rotor systems. That aircraft has flown in excess of 200 knots without issue, despite being designed for 160 knots cruise speed. Bell intends the Invictus to cruise efficiently at 180 knots. “We flew [the 525] until we said we're done, but that rotor wasn't done,” said Josh O'Neill, senior manager for technology and evaluation on the Bell 525 program. “So we went not just 201 knots. It was a good bit more than that.” The 525 Relentless was the first aircraft Bell designed “totally in the 3D space,” O'Neill said, and the Invictus is similarly using a digital thread, enabling things like virtual reality maintaining exercises to provide design feedback without a physical product. “You have a digital thread, the same part that's used when you design your aircraft is used in the maintenance training, used throughout the product,” said O'Neill. “You design the aircraft in 3D, lay out all the systems and you're able to go in there with an actual maintainer. So we pulled [a line maintainer] and had him put the gloves on and go maintain the aircraft. And you can see in the 3D space, I need to reach around this piece, I need to turn my hand in a way that the human hand doesn't like to be turned. So we need to move that item.” As a fly-by-wire aircraft designed with a modular open systems architecture (MOSA) approach, Bell believes Invictus will provide the Army with an path to autonomy — or enable a single person in the aircraft to focus on mission functionality — similar to Bell's approach with the V-280 Valor, its offering for the Future Long-Range Assault Aircraft (FLRAA) competition. Bell officials said they are currently introducing autonomous flight software and performing software regression tests for that aircraft and intend to begin autonomous flight tests within the next few months. In March 2020, when the Army narrows the FARA competition from five companies to two, Bell's team will be nine months into design. After that, two of the five designs — selected from Sikorsky, Bell, Karem Aircraft, AVX/L3Harris, and Boeing — will be selected to participate in a fly-off slated for the second half of 2022. The Army hopes to field the first FARA aircraft in 2028. https://www.aviationtoday.com/2019/12/15/bell-invictus-offer-army-lower-risk-path-fara-capabilities/
