  Air Force Eyes Drones For Adversary And Light Attack Roles As It Mulls Buying New F-16s

  The future of the U.S. Air Force's tactical aircraft fleet is under review, with some radical ideas under discussion. BY THE WAR ZONE STAFF JANUARY 22, 2021 The U.S. Air Force is in the midst of a major review of its tactical aircraft fleets. This includes investigating the possibility of using drones equipped with the artificial intelligence-driven systems being developed under the Skyborg program as red air adversaries during training, and potentially in the light attack role. The service is also exploring a potential purchase of new F-16 fighter jets, likely based on the Block 70/72 variant, two decades after the service ordered its last Vipers as it shifted focus to the F-35A Joint Strike Fighter. In an interview with Steve Trimble, Aviation Week's Defense Editor and good friend of The War Zone, earlier this month, which you can find here, now-former Assistant Secretary of the Air Force for Acquisition, Technology, and Logistics, Will Roper, provided insight into the ongoing tactical aircraft review, including particularly intriguing comments about forthcoming unmanned aircraft system programs and buying additional F-16s. These and other ideas are being scrutinized as the service looks toward its Fiscal Year 2023 budget request, which, barring any complications, would be unveiled in the spring of 2022. Roper had been the chief architect and advocate of the Air Force's Skyborg program, which the service revealed in 2019, and is developing a suite of new autonomous capabilities for unmanned aircraft with a heavy focus on artificial intelligence (AI) and machine learning. The service has said that the goal is to first integrate these technologies into lower-cost loyal wingman type drones designed to work together with manned aircraft, but that this new “computer brain” might eventually control fully-autonomous unmanned combat air vehicles, or UCAVs. The Skyborg effort has been heavily linked to other Air Force programs that are exploring unmanned aircraft designs that are “attritable.” This means that they would be cheap enough for commanders to be more willing to operate these drones in riskier scenarios where there might be a higher than average probability of them not coming back. With this in mind, Skyborg technology has previously been seen as ideal for unmanned aircraft operating in higher-threat combat environments. However, in the interview with Aviation Week, Roper suggested that they might also first serve in an adversary role. In this way, these unmanned aggressors would test combat aircrew, either standing in for swarms of enemy drones or conducting the kinds of mission profiles for which an autonomous control system would be better suited. As the proliferation of advanced drone capabilities continues, adversary drone training systems will become a pressing capability. Even using drones to stand in for or augment manned adversary platforms is one of the potential solutions to the problem of needing far more targets in the air at one time to stress fleet pilots. Operating huge fleets of manned adversaries is highly cost-prohibitive. For example, Air Combat Command shortlisted seven companies for a combined total of $6.4 billion of potential aggressor contract work in 2019; details of the first five bases to receive this support were revealed last year, as The War Zone reported at the time. Other solutions, including augmented reality, are being looked at to solve this problem, as well. You can read more about this issue in this past exclusive of ours. “I think, at a minimum, attritables ought to take on the adversary air mission as the first objective,” Roper said. “We pay a lot of money to have people and planes to train against that do not go into conflict with us. We can offload the adversary air mission to an artificially intelligent system that can learn and get better as it's doing its mission.” Roper's specific mention here of attritable drones is interesting and could perhaps hint that the manned aircraft they would battle with might, at least on some occasions, also shoot them down. If that were to become a reality, it would provide pilots with a highly realistic element to their training that would potentially be far more valuable than the relatively “canned” type of live-fire gunnery or missile firing that they are exposed to today. The Air Force Research Laboratory (AFRL) is already in the midst of an effort, separate from Skyborg, to develop an autonomous unmanned aircraft that uses AI-driven systems with the goal of having it duel with a human pilot in an actual fighter jet by 2024. Roper also clearly sees the use of drones equipped with the Skyborg suite of systems as a potential way to bring down the cost of the entire red air training enterprise, reducing the requirement to procure more expensive manned aircraft and teach the instructors required to fly them. Beyond cost-saving, however, there is still a demand for higher-end red air capabilities, especially stealthy ones, that contractors can't really provide. This is one of the reasons why early-model F-35s have been chosen to equip a future aggressor squadron. While this will go some way to meeting the demand for advanced threat simulation, it is likely to be a limited and costly fleet. Stealthy, but attritable drones, such as the XQ-58 Valkyrie, would certainly be a possibility for adding additional capacity here at a lower cost. As well as training the human elements, introducing Skyborg-enabled drones into large-force exercises would also help train them, enhancing their own AI algorithms, and building up their capabilities before going into battle for real. Essentially, algorithms need to be tested repeatedly to make sure they are functioning as intended, as well as for the system itself to build up a library of sorts of known responses to inputs. Furthermore, “training” Skyborg-equipped drones in this way in red air engagements inherently points to training them for real air-to-air combat. Air-to-air combat isn't the only frontline role the Air Force is eying for drones carrying the Skyborg suite. “I think there are low-end missions that can be done against violent extremists that should be explored,” Roper said. This opens up the possibility that lower-cost unmanned aircraft using AI-driven systems could help the Air Force finally adopt a light attack platform after more than a decade of abortive efforts in this regard. Despite initial plans to buy hundreds of aircraft, the service dramatically scaled back its most recent attempt, known as the Light Attack Aircraft program, in 2019. U.S. Special Operations Command (SOCOM) subsequently tried to revive the project, but Congress blocked that effort in its annual defense policy bill, or National Defense Authorization Act (NDAA), for the 2021 Fiscal Year. So, there remains a requirement for a light attack platform that could potentially be filled by an advanced unmanned alternative. In the meantime, the Air Force had also attempted to cease buying MQ-9 Reaper drones, which currently undertake many of these types of lower-end combat missions, but this was ultimately blocked by Congress, too. Still, close air support (CAS) is a mission that still benefits hugely from a human in the cockpit. As such, the exact capability set of a semi-autonomous drone, in this regard, may be limited. One could imagine giving the targeting control directly to those the drone is tasked with supporting on the ground though. This could compress the kill-chain and help with providing CAS in contested environments where a stealthy and attritable airframe may be overtly beneficial. Just such a concept was floated by the then Air Force Chief of Staff General Mark Welsh, who described it as “a flying Coke machine.” You can read all about that in this past article of ours. Roper had also indicated in his interview that perhaps the cost-savings from using drones in the adversary role might free up funds to otherwise address the light attack issue, as well as other needs the Air Force might have. Replacing “adversary air [with attritable unmanned aircraft] would save us money up front,” Roper explained. With regards to manned tactical aircraft, Roper also revealed in the interview that the Air Force is looking at new purchases of F-16s. “As you look at the new F-16 production line in South Carolina, that system has some wonderful upgraded capabilities that are worth thinking about as part of our capacity solution,” he said. Roper was almost certainly referring to the latest Block 70/72 variants of the F-16C/D that Lockheed Martin has been successfully selling on the export market in recent years. The company also offers an upgrade package to bring existing Vipers up to a similar configuration, known as the F-16V. In September 2020, the defense giant announced plans to standardize its F-16 offerings around a base model derived from the Block 70/72 configuration, which you can read about more in this past War Zone piece. New Vipers based on this standardized model are what the Air Force would likely be looking to buy in Fiscal Year 2023 or beyond. The latest Block 70/72 jets are already highly capable, featuring sophisticated avionics, mission systems, active electronically scanned array radar, extended range, and a digital electronic warfare suite. In the meantime, the Air Force is working hard to wring the most out of existing F-16 inventory, updating many with the Scalable Agile Beam Radar (SABR) and the new electronic warfare package from the Block 70/72.

  To get more female pilots, the Air Force is changing the way it designs weapons

  Valerie Insinna WASHINGTON — In 2022, the U.S. Air Force will take delivery of the F-15EX, a new and improved version of the nearly 40-year-old F-15E Strike Eagle. But for all of the modern advances of the new jet, only 9 percent of women in the Air Force currently meet the body-size standards for piloting the legacy F-15 and possibly also the new EX variant, potentially blocking highly qualified pilots from flying a platform that will be in operation for decades to come. Like the vast majority of the Air Force's aircraft and aircrew equipment, the F-15 was designed to meet the anthropometric specifications of a male pilot in 1967. But in an Aug. 4 memo, the Air Force mandated that future weapons programs use current body size data that reflects the central 95 percent of the U.S. recruitment population — a move meant to make pilot and aircrew jobs more accessible to women and people of color. Air Force acquisition executive Will Roper, who signed off on the changes, said there is a strategic imperative for opening the door to a more diverse pool of pilots and aircrew. During a war with a near-peer, technologically advanced nation like China, the U.S. military will have to contend with a well-trained, highly educated force that might outnumber its own, he said. By fielding weapon systems that can only be used by a smaller portion of the U.S. population, the Air Force could be shutting out some of its most promising potential pilots or aircrew. “The human factor is a delineator and it likely will be against an adversary like China, where I believe we will have a greater propensity to trust the operator in the seat, to delegate more, to empower more and take greater risk in that delegation,” Roper told Defense News in an exclusive Aug. 6 interview. “All well and good when you're a country that's going to face a country with a population that's four times your own by the end of this decade,” he said. “But if we begin with a recruitment population that we've artificially halved because of how we design our cockpits and workstations, we've just doubled our work, and now we make every operator in the seat have to be eight times better than the counterpart they will face in a nation like China.” The new guidance directs the Air Force Lifecycle Management Center to conduct a study that will solidify a more inclusive anthropometric standard that would include 95 percent of the U.S. population eligible for recruitment in the U.S. Air Force. But until that wraps up, all new-start Air Force programs must be designed with cockpits, aircrew operating stations and aircrew equipment that accommodates eight anthropometric data sets. These eight cases use measurement data from the Centers for Disease Control and represent a range of body types including individuals who are short in stature, have short limbs or have a long torso. AFLCMC's Airman's Accommodations Laboratory will also run a three-year study that will develop separate anthropometric standards for career enlisted aviators, who perform specialized jobs onboard military aircraft including flight engineers, flight attendants and loadmasters. Currently, career enlisted aviators also must meet the 1967 anthropometric standards. ‘A hidden barrier' The legacy design parameters — which stem from a 1967 survey of male pilots and measure everything from a pilot's standing height, eye height while sitting, and reach — have effectively barred 44 percent of women from being able to fly aircraft unless they receive a waiver, with women of color disproportionately affected, the Air Force stated. Even after a waiver is granted, the pilot will remain disqualified from certain platforms regardless of his or her aptitude. Then, when future requirements are defined for new platforms or equipment, the systems are usually designed to meet the existing pool of pilots, creating a self-perpetuating problem. “It is a hidden barrier with multiple layers,” said Lt. Col. Jessica Ruttenber, an Air Force mobility planner and a leader of the Women's Initiative Team that advocated for the change in anthropometric standards. “People are trying to do the right thing, but the barriers are baked into legacy policy. And without even knowing it, they're kind of cut and pasting the same standard.” Ruttenber said the new guidance addresses the root of the problem by establishing new design specifications — ensuring platforms are engineered to accommodate a wide range of body sizes from the start of the development process, rather than papering over the problem with waivers after the fact. “[For] the next inter-theater airlift that is going to replace the C-130 or C-17, we can't get the anthropometric data wrong or women are still going to be eliminated 30 years from now. The C-130 and C-17 still eliminate one out of three women from flying it,” she said. For more than a year, the Women's Initiative Group worked with Chief Master Sgt. Chris Dawson, the career field manager for the Air National Guard's career enlisted aviators, on trying to garner funding for an anthropometric study for CEAs. “There were so many communities we had to coordinate with that we realized really quickly that this has to come from the top down or we're not going to be as successful,” Ruttenber said. After meeting with Roper, the Women's Initiative group was granted $4 million for the study. Ruttenber, a KC-135 pilot, remembers being pulled out of her first pilot training class in 2005 because her physical examination indicated that she didn't meet the standing height requirement of 5-foot-4 by a fraction of an inch. She then sought a waiver that would allow her to fly. “The process was different back then. I had to drive from base to base and get measured in each cockpit in an attempt to get an exception to policy. I went to Charleston and I got measured in a C-17, and then I went to Little Rock and got measured in a C-130,” she said. “I got measured in the KC-135 and so on and so on and so on.” Since then, the Air Force has made the process to obtain a waiver less arduous, and it recently removed the initial height requirement — although some platforms still require pilots to meet the 5-foot-4 standard. Newer aircraft such as the F-35 joint strike fighter and the T-7 trainer currently under development will also accommodate a wider height and weight range. However, Ruttenber pointed out that the specifications for legacy aircraft will remain a hurdle for the progression of female pilots. “Even if the F-35 is 97 percent accommodating for women, I still can't get there because the T-38,” which is used for fighter pilot training, “has a 41 percent accommodation envelope for women,” she said. Roper said he is working with defense contractors to see whether there can be modifications made to legacy platforms — or upgraded versions like the F-15EX — that will accommodate operators with a wider range of body sizes. But whether those changes are ultimately made will depend on if they are technically feasible and funding is available for design changes. At the time of the Aug. 6 interview, Roper had already spoken to some defense industry executives — including those from Lockheed Martin — about the new guidance and planned similar phone calls with Boeing and Northrop Grumman officials over the coming days. The reaction from industry so far has been “very positive” but “very surprised” that such bias still exists, he said. However, Roper acknowledged that more work has yet to be done. “Changing the policy is one thing. Changing the platforms is another. And that's going to require cost to do. My next job, aside from designing future systems differently — which we'll do — is to find options to bring systems into greater compliance with the new policy and then to advocate tooth and nail for the funding needed to do it,” he said. “The litmus test for the Air Force long term has got to be balancing accommodation with the technology for future platforms.” https://www.airforcetimes.com/news/your-air-force/2020/08/19/to-get-more-female-pilots-the-air-force-is-changing-the-way-it-designs-weapons/
