  The Army wants a self-directed combat vehicle to engage enemies

  By: Adam Stone While the commercial world tiptoes toward the notion of a self-driving car, the military is charging forward with efforts to make autonomy a defining characteristic of the battlefield. Guided by artificial intelligence, the next-generation combat vehicle now in development will have a range of autonomous capabilities. Researchers at Army's Communications-Electronics Research, Development and Engineering Center (CERDEC) foresee these capabilities as a driving force in future combat. “Because it is autonomous, it can be out in front to find and engage the enemy while the soldiers remain safely in the rear,” said Osie David, chief engineer for CERDEC's mission command capabilities division. “It can draw fire and shoot back while allowing soldiers to increase their standoff distance.” Slated to come online in 2026, the next-gen combat vehicle won't be entirely self-driving. Rather, it will likely include a combination of autonomous and human-operated systems. To realize this vision, though, researchers will have to overcome a number of technical hurdles. Getting to autonomy An autonomous system would need to have reliable access to an information network in order to receive commands and relay intel to human operators. CERDEC's present work includes an effort to ensure such connections. “We need resilient comms in really radical environments — urban, desert, trees and forests. All those require new and different types of signal technologies and communications protocols,” David said. Developers also are thinking about the navigation. How would autonomous vehicles find their way in a combat environment in which adversaries could deny or degrade GPS signals? “Our role in this is to provide assured localization,” said Dr. Adam Schofield, integration systems branch chief for the positioning, navigation and timing (PNT) division. In order for autonomous systems to navigate successfully, they've got to know where they are. If they rely solely on GPS, and that signal gets compromised, “that can severely degrade the mission and the operational effectiveness,” he said. CERDEC, therefore, is developing ways to ensure that autonomous systems can find their way, using LIDAR, visual cues and a range of other detection mechanisms to supplement GPS. “We want to use all the sensors that are on there to support PNT,” Schofield said. In one scenario, for example, the combat vehicle might turn to an unmanned air asset for ISR data in order to keep itself oriented. “As that UAV goes ahead, maybe it can get a better position fix in support of that autonomous vehicle,” he said. Even as researchers work out the details around comms and navigation, they also are looking to advances in artificial intelligence, or AI, to further empower autonomy. The AI edge AI will likely be a critical component in any self-directed combat vehicle. While such vehicles will ultimately be under human control, they will also have some capacity to make decisions on their own, with AI as the software engine driving those decisions. “AI is a critical enabler of autonomy,” said CERDEC AI expert Dr. Peter Schwartz. “If autonomy is the delegation of decision-making authority, in that case to a robotic system, you need some confidence that it is going to make the right decision, that it will behave in a way that you expect.” AI can help systems to reach that level of certainty, but there's still work to be done on this front. While the basics of machine learning are well-understood, the technology still requires further adaptation in order to fulfill a military-specific mission, the CERDEC experts said. “AI isn't always good at detecting military things,” David said. “It may be great at recognizing cats, because people post millions of pictures of cats on the internet, but there isn't an equally large data set of images of adversaries hiding in bushes.” As AI strategies evolve, military planners will be looking for techniques that enable the computer to differentiate objects and actions in a military-specific context. “We need special techniques and new data sets in order to train the AI to recognize these things in all different environments,” he said. “How do you identify an enemy tank and not confuse that with an ordinary tractor trailer? There has to be some refinement in that.” Despite such technical hurdles, the CERDEC team expressed confidence that autonomy will in fact be a central feature of tomorrow's ISR capability. They say the aim is create autonomous systems that can generate tactical information in support of war-fighter needs. “As we are creating new paradigms of autonomy, we want to keep it soldier-centric,” David said. “There is filtering and analyzing involved so you don't overwhelm the user with information, so you are just providing them with the critical information they need to make a decision.” https://www.c4isrnet.com/unmanned/2018/11/30/the-army-wants-a-self-directed-combat-vehicle-to-engage-enemies

  Number of Foreign Companies Within Defense Supply Chain Grew Over Past Decade, Report Says

  Reliance on foreign suppliers in the defense industrial base rose—notably in packaged software and IT services—even as calls for reshoring increase, according to a new report. Reshoring the defense supply chain may reduce national security risks, but a new report detailing a heavy dependency on goods and services from foreign countries like China shows reshoring may be easier said than done. Researchers at Govini, a decision science company supporting the defense industry, analyzed data from over 1,000 Defense Department vendors across 100 industries to show how supply chain reliance on products from foreign countries has increased over the past decade. According to the survey, the number of Chinese suppliers in DOD's base increased by a total of 420% since 2010. For cyber and information technology, two statistics stick out. The share of companies based in foreign nations in the supply chain grew the most in the packaged software and IT services between 2010 and 2019. Companies based in foreign countries made up 3% of the packaged software supplier base in 2010. That number rose to 7% in 2019. The numbers are similar for IT services: Companies based in foreign countries made up 3% of the IT services supplier base in 2010 and 7% in 2019. Tara Murphy Dougherty, CEO of Govini, told Nextgov increasing adoption of IT infrastructure is critical for the Defense Department, particularly as COVID-19 forced the agency's workforce into mass telework. But that means it is imperative DOD addresses supply chain concerns for information and communications technology. Murphy Dougherty said these two investment areas are only going to continue to grow, which means the department needs to act to clearly define its stance on IT supply chain security. “What are you doing, other than responding to some of the legislation that we've seen come out of the Hill mandating investigation of this?” she said. “It would be great to see more options.” A key mandate from Congress related to supply chain was supposed to take effect on an interim basis Thursday. Section 889 (a)(1)(b) of the 2019 National Defense Authorization Act bans agencies from contracting with companies that do business with five Chinese firms, including Huawei and ZTE. But according to a Defense News report, the Pentagon received a temporary waiver from the Director of National Intelligence pushing back the compliance date until September 30. Defense Undersecretary for Acquisitions and Sustainment Ellen Lord said at a Professional Services Council webinar Thursday she needs feedback from industry on what's working and what's not when it comes to implementing the rule. “I know we're all aligned in that we do not want adversaries in our supply chain. We don't want further theft of intellectual property. We don't want these nefarious actions going on,” Lord said. “But how do we get the language into the contracts, how do we practice the behaviors of ensuring we understand what we have in our supply chains for telecommunications equipment? What we need to do is continue to hear from you.” It's not yet clear how the brief deadline extension will affect the implementation process. Regardless, visibility down the supply chain remains a key concern. Murphy Dougherty said there needs to be more transparency in supply chains if the industry is going to address security risks. The Govini report focuses on firms in the mid-tier of the supply chain, with less visibility than a large company like Boeing. For companies further down the supply chain, U.S.-based companies make up less than half of the supplier base, according to the report. Chinese companies make up anywhere from 5% to 9% of the supplier base in the middle to lower ranges of the supply chain. Murphy Dougherty said it's going to take time to see changes in the data. How to address the industrial base at a structural level remains an unanswered question, she said, and collaboration between DOD and industry will be critical in coming up with a new system to ensure supply chain security. “It begs the question of do we have the right models in place today and the right framework for the department to get all of the goodness and partnership it possibly can out of the American commercial economy,” Murphy Dougherty said. https://www.defenseone.com/threats/2020/08/number-foreign-companies-within-defense-supply-chain-grew-over-past-decade-report-says/167767/
