  U.S. Military Exploring eVTOL Solution to Resupplying Troops

  by Nick Zazulia The U.S. military is stepping up its efforts to enlist autonomous eVTOL aircraft for a variety of missions, especially those that would reduce risk to troops, such as moving cargo in combat zones. In early January, the U.S. Air Force issued a request for information to civil eVTOL developers in a bid to evaluate options for investing in the technology. For 2020 alone, the Pentagon has allocated almost $170 million to investigate options for what it calls unmanned logistic system-air (ULS-A) capability. In Iraq and Afghanistan, U.S. forces have faced difficulty moving supplies, according to Carmine Borrelli, deputy head for logistics innovation with the Marine Corps Warfighting Lab. Valuable military aircraft often need to be kept in reserve for higher-priority missions, and even when they are used, high sustainment costs make resupply an inefficient use for them. “They [eVTOLs] have the potential to have a platform that could be cost-effective, that could go far distances and that could carry stuff, potentially, at a lesser cost than what we were doing,” said Borrelli in a press briefing hosted by the Vertical Flight Society on March 10. The Marines are partnering with both the Army and the Air Force on different projects to realize that goal through what it calls small, medium, and large unmanned logistics systems. The Office of the Secretary of Defense is allocating approximately $120 million to the efforts of the Naval Air Systems Command (Navair) with small and medium ULS-A vehicles covered by the program objective memorandum (POM-19). Another $30 million for medium-size ULS-A in combined stakeholder investment and funding from the Office of the Secretary of Defense is being put toward joint capabilities technical demonstrations that need to be completed before the POM funding can be put to use. And the fiscal year 2020 budget from Congress includes $18.5 million to advance autonomous technology, particularly in large aircraft. There is more funding for the smaller ULS vehicles, because the use case is more clearly defined, and the work is further along. Instead of usual rigid requirements, the Marine Corps is now deliberately thinking about possible use cases in terms of range. Borrelli that this approach allows more flexibility in finding the best way to use the burgeoning eVTOL technology. The Department of Defense (DoD) considers “small” ULS to be vehicles with a 60- to 150-pound payload, designed for trips within 10 or 15 miles and a daily throughput of about 1,000 pounds per aircraft. Borrelli said the Marines are finding that it's realistic for vehicles of that size to weigh as much as or less than the payload they're designed to carry. The goal is to use them for squad resupply, leveraging highly automated routines to complete simple operations without requiring much manpower. Early operational capability is scheduled for 2023 with full operational capability on the docket for 2026. A medium ULS carries 300- to 500 pounds anywhere from a 20 to 125-mile combat radius, allowing for carrying up to 5,000 pounds of cargo in a day. As with a small ULS, medium ULS can keep their weight efficient enough that payload about meets vehicle weight, though they will be used for more complicated missions, such as supplying platoons, operations between advanced bases, and more. “We're trying to anticipate the future; potentially that size range could also do casualty evacuation...if these things prove out and they are reliable enough,” Borrelli said. The Marine Corps is working with the U.S. Army Research Laboratory on medium ULS efforts. At the end of January, Navair hosted a tactical resupply unmanned aircraft systems fly-off competition in Yuma, Arizona, won by Survice Engineering's TRV-150 system, which is based on the Malloy Aeronautics tactical resupply vehicle drone platform. Other competitors included Bell, Autonodyne, AirBuoyant, Pacific Aerospace Consulting, and Chartis Federal. Borrelli said medium ULS are targeted to enter service during fiscal year 2024 or 2025, with full operational capability in 2030. The category just finished its first year of successful joint-capabilities technical demonstration flight tests as part of a three-year effort. The large ULS category is still a bit more abstract. Initially, DoD conceived of vehicles with a 2,000- to 6,000-lb payload, in some ways a replacement for Bell Boeing V-22 Ospreys or Sikorsky CH-53 Sea Stallions on shorter trips. However, as the consumer market has defined and taken shape, the military realized that scaling back to vehicles with 1,000- to 2,000-lb payloads will make more sense. “We want to seriously consider and match industry's approach,” Borrelli said. “If the market is moving toward the 1,000-pound platform—a "flying car"—and many [new eVTOL aircraft] are going to be out there, it would be in our best interest to figure out how best we can use that platform to do what we need to do. We look to ride the coattails of industry.” The military is still interested in larger vehicles that can move up to 6,000 lb, but it recognizes that isn't where the bulk of innovation is taking place right now. In the large ULS category, the Marine Corps is working with the Air Force, whose Agility Prime program was started last year to leverage the commercial VTOL industry to find more efficient ways to execute resupply missions than through its high-sustainment-cost aircraft. The military wants to use these larger ULS for company resupply in remote areas with austere landing zones and launched from a new class of small, minimally-manned ships, as well as potentially to transport troops. The vehicles would work in a radius of up to 350 miles, each handling throughputs ranging from 15,000 to 30,000 pounds per day. Early operational capability for large ULS is scheduled for 2023, with full operational capability in 2030. While the military has done less work on large ULS, it hopes to rely more on the investment of the commercial UAM industry. For large ULS, Borrelli said the same weight efficiency won't be possible, so it will take a heavier vehicle to lift 2,000 pounds. Both hybrid and fully-electric propulsion is on the table and, in either case, new propulsion technology brings infrastructure questions with it. “That's something that we have constantly in the back of our minds,” Borrelli said. “So, as we're moving to the rest of the ULS space, the ground and surface and sub-surface, we're considering where those charging stations could be or where a battery inventory would be. If we don't have a charging station, we have to have a battery inventory. It's not going to do us any good to have a considerable amount of inventory unless we can be able to charge efficiently.” https://www.ainonline.com/aviation-news/defense/2020-03-12/us-military-exploring-evtol-solution-resupplying-troops

  The drive to advance missile defense is there, but there must be funding

  By: Richard Matlock Over the past five years, missile threats have evolved far more rapidly than conventional wisdom had predicted. Best known is North Korea's accelerated development and testing of sophisticated, road-mobile ballistic missiles. But the U.S. National Defense Strategy requires renewed focus on greater powers. China has adopted an anti-access strategy consisting of new offensive missiles, operational tactics and fortifications in the South China Sea. Russia, too, has developed highly maneuverable hypersonic missiles specifically designed to defeat today's defenses. Grappling with these sobering realities demands change. The 2019 Missile Defense Review called for a comprehensive approach to countering regional missiles of all kinds and from whatever source, as well as the increasingly complex intercontinental ballistic missiles from rogue states. But programs and budgets have not yet aligned with the policy. The upcoming defense budget submission presents an important opportunity to address these new and complex challenges. The Missile Defense Agency's current top three goals are sustaining the existing force, increasing capacity and capability, and addressing more advanced threats. The first two are necessary but insufficient. The third goal must be elevated to adapt U.S. missile defense efforts to the geopolitical and technological realities of our time. For the last decade, less than 2 percent of MDA's annual funding has been dedicated to developing advanced technology, during which time our adversaries have begun outpacing us. As President Donald Trump said last January, we “cannot simply build more of the same, or make incremental improvements.” Adapting our missile defense architecture will require rebalance, discipline and difficult choices. Realigning resources to develop advanced technologies and operational concepts means investing less in single-purpose systems incapable against the broader threat. It also requires we accept and manage new kinds of risk. Indeed, meeting the advanced threat may, in the short term, require accepting some strategic risk with North Korea. The beginning of this rebalance requires more distributed, elevated and survivable sensors capable of tracking advanced threats. The most important component here is a proliferated, globally persistent space layer in low-Earth orbit consisting of both passive and active sensors. MDA may be the missile defense-centric organization best suited to developing and integrating this capability into the architecture, but there is considerable opportunity for partnering with others to move out smartly, as recently urged by Vice Chairman of the Joint Chiefs of Staff Gen. John Hyten. Partnerships with the Space Development Agency and the Air Force can be supplemented by collaborative efforts with commercial space companies. We need not do this all at once. Space assets could be fielded in phases, with numbers, capability (sensors, interceptors, lasers), missions, and orbits evolving over time. MDA demonstrated a similar paradigm with the Delta experiments, Miniature Sensor Technology Integration series and the Near Field Infrared Experiment in the past. Meanwhile, other sensors could alleviate the cost of building new, billion-dollar radar on islands in the Pacific Ocean — efforts which continue to suffer delay. Adding infrared tracking sensors to high-altitude drones, for instance, has already been demonstrated experimentally in the Indo-Pacific theater with modified Reaper unmanned aerial vehicles. These need not be dedicated assets. Sensor pod kits could be stored in theater to be deployed aboard Reapers or other platforms during heightened tensions. We must revisit boost-phase defenses and directed energy. In 2010, the Airborne Laser program demonstrated that lasers could destroy missiles in the boost phase, but deploying toxic chemical lasers aboard large commercial aircraft was fiscally and operationally untenable. Fortunately, considerable operational promise exists with recently developed solid-state lasers (the cost of which is around $2 of electricity per shot). We must move these systems out of the laboratory and build and test operational prototypes. Near-term actions to better manage risk against the rogue-state ballistic missile threat must not overtake the pursuit of these larger goals. Although the Pentagon is currently considering a 10-year, $12 billion program for a next-generation interceptor, nearer-term, cheaper options are available. Replacing each existing kill vehicle on the Ground-Based Interceptors with several smaller kill vehicles would multiply each interceptor's effectiveness dramatically. The U.S. has been developing this technology since 2006, including a “hover” flight test in 2009. Affordable solutions like this must be found. Missile defense cannot do it all. Denying, degrading and destroying enemy missile systems prior to launch must be part of the mix. But left-of-launch activities can be expensive and difficult, and reliance on a cyber magic wand carries risk, too. We need to broaden our approach to attack all parts of our adversary's kill chain. The National Defense Strategy urges that we contend with the world as it is, not as we might wish it to be — or as it previously was. To meet the threats of today and tomorrow, we must radically transform our U.S. missile defenses. It falls to the 2021 budget to do so. https://www.defensenews.com/opinion/commentary/2020/01/31/the-drive-to-advance-missile-defense-is-there-but-there-must-be-funding/
