Israelis To Boost F-35 Fleet’s Electronic Warfare

By on June 15, 2020 at 1:02 PM

TEL AVIV: The Israeli air force's F-35 special test aircraft is set to arrive in Israel, suitably enough, on the Fourth of July, along with three more Joint Strike Fighters. The arrival will start a planned process of upgrading the IAF's F-35 aimed at making them the main target supplier for the Israeli defense forces.

In November another three are scheduled to arrive, bringing the IAF's total to 27 out of the 50 in the current contract.

The special test aircraft was officially delivered to the IAF a year ago and some new systems developed by Israel have been installed. But the most sensitive systems will be installed only after the aircraft lands in Israel.

Currently, the IAF operates 20 F-35 (Adir) and uses them in combat. One of the key capabilities of the F-35 is its capability to absorb electronic signals from radars and air defense systems and to quickly classify them, geolocate them, and display them to the pilot. Then the aircraft can distribute that data to other combatants.

The critical data is collected by the aircraft's passive antennas embedded in the F-35's edges. They feed the signals information to the jet's computers. Using interferometers, the slightest time delay between when a signal hits one antenna compared to another, azimuth and range can be defined and target-quality coordinates created on where the threatening radio frequency emission is coming from.

The already very advanced ELINT system of the F-35 is going to be further upgraded by the IAF, working with Israel's defense companies.

Since the stealth fighter aircraft first arrived in Israel, some locally-made systems have been partially tested in different scenarios, but the test aircraft will allow these new systems to be put completely through their paces.

The test aircraft will enable each of the Israeli F-35s to function as a “Target Generator” for all Israeli ground and naval forces thanks to what some have described as an Israeli-built command-and-control system.

The Israeli companies that are developing systems for the IAF's F-35's are reluctant to provide details about the systems under development.

Eitan Ben Eliyahu, former commander of the IAF, told Breaking Defense that the F-35 will bring two main capabilities to the Israeli air force's existing ones: “The stealth of course is the obvious one and it is crucial in an area where different forces deploy advanced anti-aircraft systems.

“The second capability is the one that allows this aircraft to receive and distribute all kinds of combat data from a long list of sensors. This,” Ben Eliyahu said, “is very important for an air force that is performing combat missions almost on a daily basis.”

    Space Development Agency wants someone to launch its first 28 satellites

    Christina Mackenzie PARIS – The French government is to order by year-end another 12 Rafale fighter aircraft for its Air and Space Force to replace the 12 in its current inventory of 102 that are being sold to Greece. “We have the intention, between now and the end of the year, to place an order, in parallel with the orders for Greece, of 12 aircraft for the Air & Space Force," Armed Forces Minister Florence Parly told parliamentarians at the National Assembly's Defence Commission during a hearing on the defense budget. When Greece announced that it would be buying 18 Rafales from France, of which 12 would be second-hand, the French government had said that each Rafale removed from the inventory would be replaced in order not to impact operations. “I'd like to reassure you. Together we've agreed that by 2025, in conformity with the military program law, we would have 129 Rafale aircraft and I have every intention of abiding by that,” Parly said. The purchase of these new Rafales cannot be paid for with the funds that Greece will pay for their 18 aircraft. The Hellenic order is valued at “between €1 billion and €2 billion,” according to Parly's Cabinet. She explained that these monies technically would go straight into the state budget and not into her ministry's. That means a new battle is afoot with the Ministry of the Economy, Finance and Recovery about the transfer of funds into defense coffers to pay for the replacements, she admitted. In addition to this order for 12, Dassault Aviation, manufacturer of the Rafale, still has 28 aircraft to deliver to France between 2022 and 2024. The 12 new ones would be delivered “immediately after this,” according to Parly. And by 2023 the Armed Forces Ministry plans to order a further 30 which would be delivered from 2027. https://www.defensenews.com/global/europe/2020/10/08/france-moves-to-replace-the-12-rafales-sold-to-greece/

    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. For details of the event, visit https://go.usa.gov/xEZeT. A forthcoming Broad Agency Announcement will include complete program objectives, schedules, and metrics. 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

  • Government watchdog warns of cost and technical risk for next-gen combat vehicle effort

    Government watchdog warns of cost and technical risk for next-gen combat vehicle effort

    By: Jen Judson WASHINGTON — The Government Accountability Office is warning the Army its approach to cost estimates and technical development for its Optionally Manned Fighting Vehicle program is risky and should be amended, according to an August 6 report. The Army has already struggled to get the OMFV program, intended to replace the Bradley Fighting Vehicle, off the ground, canceling its previous solicitation to compete after receiving just one bid from General Dynamics Land Systems last fall. And GAO, in its report, is concerned that the service's newest attempt to get after delivering an OMFV comes with risk because the program documentation “does not clearly communicate the uncertainty associated with projected costs” and limits the program's “ability to gather the knowledge to effectively mitigate risk associated with system design maturity.” For one, the Army has come up with a singular cost estimate for the life-cycle of the program rather than a range of potential costs that takes uncertainty into account, according to the report. The OMFV program cost estimate, the report notes, is roughly $46 billion in fiscal 2019 dollars. “Our past work has determined that a point estimate alone is insufficient for managers to make informed decisions about the cost of a program,” the GAO writes. “For informed decisions, the cost estimate must reflect a degree of uncertainty, typically achieved through an uncertainty analysis, so that level of confidence can be given about the estimate.” For example, the OMFV program will be optionally manned, “which adds complexity and unknowns to the design as no vehicle like this currently exists in the Army's ground vehicle fleet,” the GAO said. “But the uncertainty surrounding this complex design is not reflected in the point estimate.” And because of this “decision makers are left making choices without a clear understanding of the impact on costs and may not be able to accurately budget for the program,” the report states. The constrained development schedule for OMFV is also a cause for concern as it inevitably drives risk into the program. GAO notes the Army had laid out, in its previous solicitation, a plan to design and demonstrate an OMFV prototype in three years and three months, but has since spread the schedule out a bit more with the relaunch of the program and now plans to complete system development and prototype demonstration in “close to” five years. The new solicitation also lays out a five-phase effort that will allow the Army to reassess the process at certain checkpoints throughout development, according to the report. The GAO also found promise in the Army's plan to use a modular open systems architecture to incorporate incremental upgrades. In the Army's previous plan for OMFV it also planned to use a mix of existing and new technologies but, the GAO report states, the program did not include plans to complete an independent technology readiness assessment until it was approaching a production decision. According to the Office of the Under Secretary for Defense for Acquisition and Sustainment, in a report to Congress, “the least mature technology for OMFV had only been demonstrated at the component level in a laboratory environment,” the report notes, adding that the level of technology maturity would require “significant” additional development before it could be added to a weapon system. “The Army is maturing, or has plans to mature, individual technologies to a level lower than the threshold recommended by leading practices before beginning system development,” the report says. “This creates a danger of limited insight into key technology risks.” Critical technologies, GAO states, should be demonstrated in “an operational or realistic environment — not simply in a relevant environment — prior to their incorporation into a system design to ensure that they work as intended for the end-user.” The GAO adds, based on past experience, that without proving out technology at that level, the Army risks the possibility that new capabilities won't work as planned and will require further maturation, which results in schedule slips and rising costs. In the previous competition, OMFV didn't hold a systems engineering design review before beginning system development and the Army canceled the solicitation “in part due to the conclusion that contractors could not complete a system design that met requirements within the given schedule,” the report notes, which “illustrates the risk of beginning system development without conducting a systems engineering design review.” Program officials told the GAO that the program office and requirements developers “may have misjudged the ability of contractors to integrate the desired technology within the given schedule.” The GAO recommends the Army secretary direct the OMFV program office to include a range of cost estimates to support a range of possible outcomes as well as conduct systems engineering reviews at key decision points. The report also lays out similar findings on the Mobile Protected Firepower program, which is heading into competitive prototype testing this summer. General Dynamics Land Systems and BAE Systems are competing to build the new light tank for Army infantry. The GAO recommended the Army should ensure the MPF program also include a range of cost estimates that account for uncertainty. https://www.defensenews.com/land/2020/08/06/government-watchdog-warns-of-cost-and-technical-risk-for-next-gen-combat-vehicle-effort/
