  US Army floats the option of fielding high-altitude balloons

  By: Jen Judson WASHINGTON — The U.S. Army is now carving out a path to field high-altitude balloons to provide an additional but less expensive layer of communications, connectivity, range extension and surveillance capabilities, adding resiliency to the service's existing architecture of space assets and aircraft supporting multidomain operations. Recent tests and experiments with high-altitude balloons at White Sands Missile Range, New Mexico, left an impression on the head of the Army's Space and Missile Defense Command. “It's just phenomenal what we're able to do with high-altitude balloons,” Lt. Gen. Daniel Karbler told Defense News in an interview ahead of the Association of the U.S. Army's annual conference, which took place virtually Oct. 13-16. “I don't have the cost analysis but, in my mind, pennies on the dollar with respect to doing it. If I had to do it via a [low-Earth orbit] or some satellite constellation, what we are able to provide with high-altitude balloons, it's tactically responsive support to the war fighter,” he added. Karbler said he sees the balloons supporting the Army's Multidomain Task Force in the future. “Conceptually, with the types of missions that the Multidomain Task Force is working, the high-altitude balloons would be a key capability enabler,” Brent Fraser, concept development division chief at SMDC's Space and Missile Defense Center of Excellence, told Defense News in an Oct. 29 interview. “[The balloons would] be able to provide some beyond-line-of-sight capability, whether it's communications, extended distances, to be able to provide the ability to enable sensing of targets deep in the adversary's areas, to be able to reinforce and complement existing sensing systems other than the aerial layer as well as the space layer,” Fraser added. In terms of war games and experiments conducted with high-altitude balloons, “as we look at a number of emerging concepts and capabilities and formations,” he explained, “I think we still have a ways to go, but I think we're on a positive path to continue.” SMDC has been working on high-altitude balloons — basically dirigibles that can camp out roughly 60,000-90,000 feet in the air — for a long time, but recently the technology has improved, particularly through the commercial market. Google, for instance, used high-altitude balloons to help Puerto Rico after Hurricane Maria to help establish internet connectivity. Duration is one of the areas that has greatly improved. High-altitude balloons can now stay aloft for weeks, if not months, rather than just hours or days. Users can also command and navigate the balloons better than before, and the platforms can more easily be recovered after missions. “The technology readiness levels have really come a long way,” Fraser said. SMDC has partnered with Army Futures Command to advance the technology, particularly involving the latter's Assured-Positioning, Navigation and Timing cross-functional Team as well as Training and Doctrine Command, the Army Intelligence Center, and cyber and special operations personnel. Several years ago, the Army developed a high-altitude concept that established a foundation on which to build, Col. Tim Dalton, Army capability manager for space and high altitude within the SMDC's center of excellence, said in the same interview. After integrating the concept into a variety of war games with Futures Command and other entities, the Army is starting to develop requirements. “We're in the initial stages of defining what those requirements would be,” Dalton said. “There's kind of two aspects to the high-altitude piece: the high-altitude platform, so it's the balloon, and then whatever it's carrying on there for a payload.” The Army has created initial documents for staffing through Futures Command, and over the next couple of years the service will run those requirements through the Joint Capabilities and Integration and Development System process, which will lead to review by the Army Requirements Oversight Council. The service is in the early stages of figuring out what a program of record would look like, but it has some options, Dalton said. “What we're kind of hoping to do over the next couple of years as part of our campaign of learning is to help define what that looks like and the best way to resource those requirements for the Army.” https://www.defensenews.com/digital-show-dailies/ausa/2020/11/09/us-army-floats-the-option-of-fielding-high-altitude-balloons/

  As Army’s Shadow to fade from view, Textron looks to a successor

  By: Valerie Insinna WASHINGTON — In the crowded exhibit halls of the U.S. Army's largest conference, a strange-looking drone — a small, flat, tailless, triangular aircraft with four flexible rotors — is suspended above a room full of giant wheeled vehicles and static helicopter displays. That aircraft, Textron's X5-55 demonstrator, hasn't been built for a customer or a particular mission, but the company believes that some of the technologies it plans to mature on the X5-55 could be spun off for future U.S. military requirements like a replacement to Textron's own RQ-7 Shadow. The goal is not to come to the services with a family of new products it can adopt, said David Phillips, Textron's senior vice president and general manager for unmanned systems. Instead, it plans to use the X5-55 as a test bed to mature new propulsion, rotor assembly and fuel cell technologies. “We're not going to say, ‘here's your product,' but we'll listen to them and we'll be ready,” he told Defense News in a Oct. 8 interview. “We know what our deployed customers want. Everything is about smaller, smaller, smaller, and doing more and [being] easier to operate and more agile and more flexible and quieter.” What sets the X5-55 apart from other drones is its vector thrust technology that allows it to take off vertically, hover, transition to normal flight and land vertically using the four electric rotors, whereas other drones that vertically take off but fly like an airplane — like the company's Aerosonde hybrid quad unmanned aircraft system — use electric-powered rotors for vertical flight and a heavy fuel engine to power their propeller during horizontal flight. “The logic allows the system, basically, literally to eliminate what we call flight control surfaces. So you won't see ailerons. You won't see flaps, you won't see servos and those things that control the elevation, climb and descend in normal flight,” he said. “That's all done with the vector thrust. We change how those electric motors and the props work in tandem to be able to climb or descend.” Textron unveiled the X5-55 this May at the Association for Unmanned Vehicles International Xponential conference, but the version shown this week at the Association of the U.S. Army's annual conference has already been modified with new propulsion pods and rotor assemblies that help enable vector thrust, as well as landing gear that protects the underside of the drone as it touches down. The demonstrator flies every several weeks at Textron's schoolhouse at Blackstone, Virginia. And over the next few months, the company plans to continue testing the drone's ability to move from hover to standard flight, as well as eventually work up to endurance flights that prove how long the UAS can remain airborne. Although the Army does not have a formal requirement for a Shadow replacement, officials have expressed interest in fielding one soon. Earlier this year, Brig. Gen. Wally Rugen, who runs the Army's Future Vertical Lift program, called a Shadow replacement an area where there is “potential, anyway, for a quick win,” and said that it should take a few years — not a full decade — to be able to field a new, runway-independent drone for the service. “We are talking much, much shorter, so when I'm talking ‘soon,' I'm talking just several years, not distant future,” he said. https://www.defensenews.com/digital-show-dailies/ausa/2018/10/08/as-armys-shadow-to-fade-from-view-textron-looks-to-a-successor
