Andrew Eversden The Army's new network tools, set to be deployed to units in 2021, were heavily influenced by a new factor: soldiers. Through exercises and training events, the Army's Network Cross-Functional Team received feedback on its design decisions for Capability Set '21, the set of new network tools set to be delivered to soldiers next year as part of the service's network modernization efforts. “This is the first time really in recent history that the network has really focused on soldier feedback. And it's important and it played a huge role in that,” said Col. Garth Winterle, project manager for tactical radios at the Army's Program Executive Office Command, Control, Communication-Tactical. The Army recently completed its critical design review of Capability Set '21 and is in the beginning stages of procuring network pieces for delivery. In the lead-up to making purchases, feedback from units helped show the differences between how the new network tools perform in the field versus in a lab. “Soldier ingenuity, leader know-how, the skill craft that our soldiers bring and the tradecraft they utilize in the field is a lot different than how we conceptualize it back here,” Col. Rob Ryan, deputy director of the Network CFT at Army Futures Command, said at a C4ISRNET event in June. Testing for the capability set has been ongoing in lab-run experiments and with limited field tests in the last few months. Through the field experiments, the Army modernization team received feedback from units on what volume of various capabilities the soldiers needed, what capabilities were usable and what “attributes” of each capability soldiers found to be more important than others, said Winterle. Disruptions caused by both the coronavirus pandemic and a deployment of the 82nd Airborne Division to the Middle East at the end of December forced the modernization team adjust its testing plans. Defender 2020, a massive exercise scheduled to take place in June with European allies, was altered. Army leaders had planned to use the event to test network equipment with allies. However, network tests are “back on the calendar” in the fourth quarter of fiscal 2020, Winterle said. “The design decisions that were made at critical design review are still up on the table for revision or reassessing after continual soldier feedback,” Winterle said. “This is a continual evaluation, continual process.” Maj. Gen. Peter Gallagher, director of the Network CFT, said in a June 9 webinar with industry that several testing events, like a Joint Warfighting Assessment and Defender 2020, were altered, as were combat training center rotations and other exercises. Those “are always great venues for us getting feedback from soldiers and leaders on improving the network design,” Gallagher said. Ryan said that the network team received feedback from soldiers during the development, build and delivery phases of network design. In forthcoming testing events, the Army wants to figure out how many radios are needed and where they need to be located, Winterle said. The service also plans to evaluate if it undervalued and overvalued certain capabilities. https://www.c4isrnet.com/yahoo-syndication/2020/07/30/from-the-lab-to-the-battlefield-soldiers-put-new-network-tools-to-the-test/

Steve Trimble In December 2018, General Atomics Aeronautical Systems executives still felt the bitter sting of a losing bid two months earlier for the U.S. Navy MQ-25 contract, but a clearly disappointed company president vowed to return for the next competition against the aerospace industry's largest companies. “If the [request for proposals] comes out for a major program of record, we're all-in,” said David Alexander in that December 2018 interview in his offices in Poway, California. “We'll maybe have a few more lessons learned on what to do and what not to do,” he added. "But we'll go in with both feet planted again and go after it.” Eighteen months later, General Atomics Aeronautical Systems (GA-ASI) is doubling-down on Alexander's commitment, releasing exclusively to Aviation Week a concept rendering of a next-generation unmanned aircraft system (UAS) that reflects the characteristics the company's designers view as essential for the class of aircraft that could replace the MQ-9 by the early 2030s. Ultra-long-endurance UAS proposed GA-ASI hints at propulsion advances GA-ASI was among at least five industry teams that responded to the U.S. Air Force's request for information (RFI) for a next-generation intelligence, surveillance and reconnaissance (ISR) and strike UAS to enter service in fiscal 2030. Northrop Grumman and Lockheed Martin shared concepts for next-generation UAS designs on Sept. 11. Boeing and Kratos also responded to the Air Force RFI by the July 15 deadline but declined to release concepts at this nascent stage of the bidding process. Arguably, GA-ASI invented the role of the ISR/Strike UAS with the MQ-9, and the company's concept for the Reaper is no less provocative, featuring a jet-powered aircraft with distinctive, tear-shaped inlets and a long, high-aspect-ratio wingspan that appear optimized for ultra-long-range flight at high altitudes. “We're embracing ultra-long endurance to keep our next-generation ISR/Strike UAS in the fight for longer periods than many ever imagined possible,” Alexander said in a statement to Aviation Week. Although GA-ASI released no specifications with the rendering, it is clear Alexander means the next-generation concept should have even longer range that the 27-hr. endurance currently offered by the Air Force's MQ-9. The Air Force Research Laboratory defined ultra-long-endurance in 2019, when a popular light sport aircraft, the Pipistrel Sinus, was modified to fly autonomously for 2.5 days over the Dugway Proving Ground, Utah. The modified aircraft was called the Ultra-Long-Endurance Aircraft Platform. How the new GA-ASI concept achieves ultra-long endurance is likely to include intriguing surprises beyond the disproportionately long, thin-chord and highly swept wings. The tear-shape inlets appear to feed airflow through parallel ducts down the middle of the fuselage into a mysterious propulsion system. Alexander's statement hints that the aircraft's engine is a critical element of the ultra-long-endurance capability. “Our advancements in propulsion technology will give commanders a longer reach than ever before,” Alexander said. In the late-1990s, GA-ASI designed the MQ-9 to perform the hunter-killer UAS mission's three “F's”—find, fix and finish—by itself if necessary, with a targeting sensor embedded beneath the nose and AGM-114 Hellfire missiles along with GBU-12 laser-guided or GBU-38 GPS-guided gravity bombs under the wing. GA-ASI's next-generation UAS concept appears capable of performing the role in a similar stand-alone fashion. A faintly visible bulge under the leading edge suggests capacity for a large payload bay, allowing the future concept to carry sensors and weapons internally, unlike the MQ-9. But the Air Force's concept of operations is changing. Whether manned or unmanned, any aircraft in the future combat fleet must be capable of finding and striking targets on their own, but they are expected to be able to operate as part of a network. Data from onboard sensors must be shared to the network, and data coming from other sensors elsewhere on the network must be receivable. GA-ASI's concept is adapted to that approach, Alexander said. “We envision [the] next-gen ISR/Strike [aircraft] as a conduit, supplier and consumer of information,” hesaid. “We believe it is imperative that future unmanned systems are able to communicate, share information and collaborate—together and intuitively with their human counterparts—across systems and domains in record time.” The next-generation UAS also addresses the workforce needed to operate the MQ-9, including separate teams of pilots and sensor operators during cruise flight and takeoff and landing. GA-ASI notes that the company has already qualified technologies to enable the existing fleet to taxi, take off and land automatically as well as a ground control system that allows a single pilot to control six UAS. “Our team has been developing and delivering automation solutions for years,” Alexander said. https://aviationweek.com/shows-events/afa-air-space-cyber-conference/reaper-replacement-reveals-bold-new-ga-asi-vision
