    Air Force not considering new F-15 or hybrid F-22/F-35, top civilian says

    By: Valerie Insinna WASHINGTON — The two biggest manufacturers of military aircraft have been busy marketing new versions of their fighter jets to the U.S. Air Force, but the service's top official told Defense News in an exclusive interview that it's not actually interested in purchasing either of them at the current moment. This summer, Defense One broke two major stories about sales pitches from Boeing, which is proposing an advanced version of the F-15 to the Air Force, and Lockheed Martin, which has been pushing a hybrid version of the F-22 Raptor and F-35 joint strike fighter similar to what it is reportedly offering Japan. But just because those companies are offering new jets, doesn't mean that the Air Force wants them. In an exclusive Sept. 5 interview, Air Force Secretary Heather Wilson said she believes the service needs to expend its precious financial resources on stealthy, fifth-generation platforms — specifically the F-35 — and thus buying even an advanced fourth generation fighter like the so-called F-15X is not in the cards. "We are currently 80 percent fourth-gen aircraft and 20 percent fifth generation aircraft,” she said. "In any of the fights that we have been asked to plan for, more fifth gen aircraft make a huge difference, and we think that getting to 50-50 means not buying new fourth gen aircraft, it means continuing to increase the fifth generation.” What about a new fifth generation plane that would combine the F-35 and F-22? Wilson shut down that idea as well, saying that proposal "is not something we're currently considering.” In a statement, a Lockheed spokesman said that the company was focused on the F-35 program but also looking into generational leaps in capability “to ensure our technology, including existing aircraft, remains a step ahead of advancing threats.” Boeing declined to comment on this story. The Air Force secretary's proclamations seem to pour cold water on both Lockheed and Boeing's sales pitches, but it is always possible that others inside the service are in favor of buying the F-15X and F-22/F-35 hybrid — and that they could continue making the case to Air Force leadership, potentially winning them over. Sources that spoke to The War Zone said Boeing was in “very serious” talks with the Air Force over the F-15X, but that the service had shied away from making its interest public so as to not to derail it's number-one procurement priority, the F-35. Defense News has also heard from multiple sources that the Air Force has been in talks with Boeing over the F-15X for over a year, though it's unknown at what levels those conversations currently reside. Experts who spoke with Defense News said it's very likely that the Air Force intends to keep its focus on ramping up F-35 production for the time being, but that alternative platforms could very well be considered in future years. However, it is the F-22/F-35 hybrid, not the F-15X, that they believe stands a better chance of being adopted by the Air Force. Defense One, which broke the story about Lockheed's hybrid offer, wrote that the proposed jet would involve taking the F-22 airframe and outfitting it with some of the F-35's more advanced mission systems, though some structural changes could also be involved. “Every F-22 hybrid or derivative I've seen has been great,” said Rebecca Grant, a defense analyst with IRIS independent Research. The Air Force is in great need of such a stealthy air superiority aircraft because it only procured 183 F-22s, she said. Its other plane that specializes in the air-to-air fight, the F-15C/D, was originally fielded in the 1970s. Grant said she interprets Wilson's dismissal of the F-22/F-35 hybrid as a reflection of near-term requirements and priorities, noting that “job one is acquiring the F-35.” But in the future, that jet could be what the service decides it needs to contend with current and future threats. David Deptula, the dean of the Mitchell Institute for Aerospace Power Studies and a retired Air Force lieutenant general, agreed that the service should continue buying F-35s for the time being. However, the F-22/F-35 hybrid might be a good option for the service in the future, when it begins looking for a next-generation air superiority jet, which the Air Force has variously called Penetrating Counter Air and Next Generation Air Dominance.

    DARPA: Understanding Warfighter Performance from the Inside Out

    Measuring Biological Aptitude (MBA) aims to identify, understand, and monitor in real time the biology that underlies success in specialized roles A new program out of DARPA's Biological Technologies Office could help the Department of Defense enhance and sustain military readiness both by revolutionizing how troops train, perform, and recover, and by mitigating shortages of highly qualified candidates for extremely specialized roles. The anticipated outputs of the Measuring Biological Aptitude (MBA) program are a set of biomarkers — measurable indicators of biological processes — that correspond to traits of highly effective performance in a given role, along with new tools to measure and report on those biomarkers in real time. This information will enable individual warfighters to understand and affect the underlying biological processes that govern their success. MBA technologies could improve training, team formation, mission performance, and post-mission recovery, yielding a better prepared, more effective, more resilient force. At its core, MBA seeks to shed light on the biological factors and processes that support peak performance in each of a set of military specializations. The research will work backwards from phenotypes — that is, how an individual's fixed genetic code expresses as externally observable cognitive, behavioral, or physical traits — and attempt to establish the biological mechanisms that translate underlying genetic makeup into phenotypic traits. At present, those mechanisms of translation — also known as expression circuits — are largely a mystery. MBA researchers will develop new assays and technologies to monitor and report on the biomarkers that reveal the activity of key expression circuits. “With existing technology scientists are able to read out genotype and measure and observe certain aspects of phenotype. Most of what happens in between is a black box,” said Eric Van Gieson, the MBA program manager. “DARPA believes that the information inside the box — these expression circuits — can be predictive of how an individual will respond to a given stimulus or scenario, and more importantly, we believe it will help inform the individual on how to improve their performance throughout their career.” Researchers supporting MBA will initially analyze samples and other data collected from high-performing troops across select military specializations to identify biological signatures of successful performance in each of those roles and determine how they can be measured. For instance, maintaining a lowered heart rate during combat is a valuable trait and easily measured with existing wearable technology. Adaptable problem solving, resilience, and cognitive flexibility are extremely valuable, but less easily measured. MBA analyses should reveal an array of such traits and the expression circuits responsible for them. If DARPA succeeds, the resulting MBA system could support military readiness in various ways. The first improvement relates to how the military initially evaluates recruits and subsequently develops candidates for specialized roles. Many of these roles currently suffer from shortages of qualified candidates, even as more pervasive use of complex technologies and an expanding set of mission profiles are increasing demand for uniquely skilled personnel. For at least the past 50 years, initial assessment of military service members has remained essentially unchanged, comprising a basic medical screening, a standardized physical readiness test, and a written test known as the Armed Services Vocational Aptitude Battery (ASVAB) for enlisted personnel. Scores on the ASVAB feed into the preliminary determination of an individual's qualification for certain military occupational specialties. As a service member's career advances, future placement into other roles does not follow a prescribed protocol and can be based in large part on subjective measures. Against this backdrop, MBA technology could increase the objectivity of the criteria used by military selection committees, remove biases, and raise the baseline of performance for incoming recruits. Additionally, by taking biology into account, the results from MBA measurements could reveal to individuals career options that might not be apparent based on commonly accepted, externally observable traits alone. The second improvement ties to training, both before and after an individual pursues a military career. MBA technology could allow a user to assess his or her personal potential for specialized roles and proactively nurture the traits that are characteristic of successful performers. “Genotypes are fixed, but phenotypes are not. Biology is fundamentally adaptable, and that is the key to enabling performance improvements,” Van Gieson said. “What we're planning to deliver with MBA is a set of continuously updated information that empowers individuals to track their progress throughout their careers and quickly identify what aspects of training and preparation are the most productive.” Third, during missions commanders could employ real-time reporting of changes in service members' biomarkers to inform how a military operation unfolds, adding a layer of biological awareness to provide a more complete assessment of the mission space. Commanders could shift resources or adjust strategies and tactics based on how squad members are performing. Following a mission, biomarker reporting could likewise guide recovery practices and indicate potential health issues. The overall MBA program will be informed by consultations with independent expert advisors in the ethical, legal, social, and regulatory aspects of the work, with particular emphases on privacy, data protection, and responsible utilization of data by individuals. MBA performer teams will be required to provide medical guidance as part of any human study through an embedded genetic counselor, sports therapist, or similar specialist. “Human beings are extremely complex, and although we expect to gain valuable new insights by measuring biology, we also understand that people are not locked into predetermined fates,” Van Gieson explained. “Any breakthroughs we achieve in the MBA program will necessarily be used to address shortages in critical roles by expanding opportunities, not limiting them. If we can provide people with information on their unique biology, and empower them to affect and measure gains in key traits, we'll have opened career pathways that they may not have previously considered.” DARPA will hold a Proposers Day on February 12, 2019, in Arlington, Virginia, to provide more information about MBA and answer questions from potential proposers.

Team should have experience in human performance, phenotyping, multi-scale biology, physiology, biomarker detection and tracking, device development, and various other aspects that will be specified in the announcement. https://www.darpa.mil/news-events/2019-01-22a

    Here’s how the Corps could shave about 6 pounds off your body armor

    By: Shawn Snow The Corps is in the beginning stages of researching a new, lighter alternative ballistic body armorplate for counterinsurgency style conflicts that is nearly six pounds lighter than the legacy plates. And on Thursday, it held an industry day with 16 companies vying to produce the Corps' latest body armor. The goal is to reduce battlefield fatigue and provide commanders with flexibility on the type of armor protection they decide to carry into combat, according to Keith Pierce, the armor team lead for Infantry Combat Equipment at Marine Corps Systems Command. While the current Enhanced Small Arms Protective, or ESAPI, have been highly effective in saving lives on the battlefield, they weigh nearly a combined 15 pounds, the Corps wants to shave that down to roughly 8.6 pounds for a medium-sized Marine, Pierce said. But don't expect the ESAPI to disappear just yet. The new plates are being crafted for low intensity threat environments like the counterinsurgency style wars that have embroiled American forces for nearly 20 years. While the new plates will “defeat a preponderance of threats” in low intensity conflicts, the ESAPIs will still be “critical in some threat environments,” Pierce explained to Marine Corps Times. But the changes to the new plates are still likely to be minimal. The Corps has decided to keep the same basic shape of the ESAPI, and there's unlikely to be any major changes in materials used to construct the armor plates “The materials for plates haven't had a big tech leap,” Pierce said. “A lot of people are trying to find that next leap.” The Army recently fielded a new plate, but its relatively of the same construction as the ESAPI, according to Pierce. “There may be incremental changes ... like the ceramic improving a little bit,” Pierce explained. But Pierce said he didn't expect any major changes over the next five years. “We are looking at some unique things,” he added. A lot of data and analysis is being pored over, to include assessments of the threat environment by the intelligence community for the construction of the new plates. So far, the Corps has tested a prototype of the lighter plates and found Marines had nearly eight percent faster mobility over the heavier ESAPIs. The new plates — when combined with the new Plate Carrier Gen III system — will reduce a Marine's load burden by a total of eight to 10 pounds, according to Pierce. The Corps expects to award a contract sometime in fiscal 2019 for the lightweight plates, and fielding might kick off in 2020, Pierce said. https://www.marinecorpstimes.com/news/your-marine-corps/2018/09/27/heres-how-the-corps-wants-to-shave-about-6-pounds-off-body-armor/
