  Lutte anti-drone : l'armée française teste l’HELMA-P de CILAS

  La ministre des Armées, Florence Parly, a assisté mercredi sur le site de la DGA Essai de missile, à Biscarrosse, à une démonstration de destruction en vol d'un mini-drone au moyen d'un laser. Le système HELMA-P, développé par la pépite CILAS, filiale d'ArianeGroup, est composé d'un radar pour détecter les drones jusqu'à 3 kilomètres, d'un système de pointage pour suivre la cible et d'un laser pour le neutraliser. Il peut « soit brûler le drone soit l'éblouir avec un tir de précision ». D'une portée d'un kilomètre, le laser est d'une puissance de 2 kW et détruit sa cible en moins d'une dizaine de secondes. Le système devrait être opérationnel en 2024. « A moyen terme, pour renforcer notre défense anti-drones, nous travaillons sur le développement de lasers de puissance, et c'est ce que vous nous avez montré aujourd'hui », a souligné la ministre. Parmi les armées occidentales, seuls les Américains et les Israéliens ont développé des capacités similaires. En Allemagne ou au Royaume-Uni, des recherches se poursuivent aussi.

  Reaper Replacement Reveals Bold New GA-ASI Vision

  Steve Trimble In December 2018, General Atomics Aeronautical Systems executives still felt the bitter sting of a losing bid two months earlier for the U.S. Navy MQ-25 contract, but a clearly disappointed company president vowed to return for the next competition against the aerospace industry's largest companies. “If the [request for proposals] comes out for a major program of record, we're all-in,” said David Alexander in that December 2018 interview in his offices in Poway, California. “We'll maybe have a few more lessons learned on what to do and what not to do,” he added. "But we'll go in with both feet planted again and go after it.” Eighteen months later, General Atomics Aeronautical Systems (GA-ASI) is doubling-down on Alexander's commitment, releasing exclusively to Aviation Week a concept rendering of a next-generation unmanned aircraft system (UAS) that reflects the characteristics the company's designers view as essential for the class of aircraft that could replace the MQ-9 by the early 2030s. Ultra-long-endurance UAS proposed GA-ASI hints at propulsion advances GA-ASI was among at least five industry teams that responded to the U.S. Air Force's request for information (RFI) for a next-generation intelligence, surveillance and reconnaissance (ISR) and strike UAS to enter service in fiscal 2030. Northrop Grumman and Lockheed Martin shared concepts for next-generation UAS designs on Sept. 11. Boeing and Kratos also responded to the Air Force RFI by the July 15 deadline but declined to release concepts at this nascent stage of the bidding process. Arguably, GA-ASI invented the role of the ISR/Strike UAS with the MQ-9, and the company's concept for the Reaper is no less provocative, featuring a jet-powered aircraft with distinctive, tear-shaped inlets and a long, high-aspect-ratio wingspan that appear optimized for ultra-long-range flight at high altitudes. “We're embracing ultra-long endurance to keep our next-generation ISR/Strike UAS in the fight for longer periods than many ever imagined possible,” Alexander said in a statement to Aviation Week. Although GA-ASI released no specifications with the rendering, it is clear Alexander means the next-generation concept should have even longer range that the 27-hr. endurance currently offered by the Air Force's MQ-9. The Air Force Research Laboratory defined ultra-long-endurance in 2019, when a popular light sport aircraft, the Pipistrel Sinus, was modified to fly autonomously for 2.5 days over the Dugway Proving Ground, Utah. The modified aircraft was called the Ultra-Long-Endurance Aircraft Platform. How the new GA-ASI concept achieves ultra-long endurance is likely to include intriguing surprises beyond the disproportionately long, thin-chord and highly swept wings. The tear-shape inlets appear to feed airflow through parallel ducts down the middle of the fuselage into a mysterious propulsion system. Alexander's statement hints that the aircraft's engine is a critical element of the ultra-long-endurance capability. “Our advancements in propulsion technology will give commanders a longer reach than ever before,” Alexander said. In the late-1990s, GA-ASI designed the MQ-9 to perform the hunter-killer UAS mission's three “F's”—find, fix and finish—by itself if necessary, with a targeting sensor embedded beneath the nose and AGM-114 Hellfire missiles along with GBU-12 laser-guided or GBU-38 GPS-guided gravity bombs under the wing. GA-ASI's next-generation UAS concept appears capable of performing the role in a similar stand-alone fashion. A faintly visible bulge under the leading edge suggests capacity for a large payload bay, allowing the future concept to carry sensors and weapons internally, unlike the MQ-9. But the Air Force's concept of operations is changing. Whether manned or unmanned, any aircraft in the future combat fleet must be capable of finding and striking targets on their own, but they are expected to be able to operate as part of a network. Data from onboard sensors must be shared to the network, and data coming from other sensors elsewhere on the network must be receivable. GA-ASI's concept is adapted to that approach, Alexander said. “We envision [the] next-gen ISR/Strike [aircraft] as a conduit, supplier and consumer of information,” hesaid. “We believe it is imperative that future unmanned systems are able to communicate, share information and collaborate—together and intuitively with their human counterparts—across systems and domains in record time.” The next-generation UAS also addresses the workforce needed to operate the MQ-9, including separate teams of pilots and sensor operators during cruise flight and takeoff and landing. GA-ASI notes that the company has already qualified technologies to enable the existing fleet to taxi, take off and land automatically as well as a ground control system that allows a single pilot to control six UAS. “Our team has been developing and delivering automation solutions for years,” Alexander said. https://aviationweek.com/shows-events/afa-air-space-cyber-conference/reaper-replacement-reveals-bold-new-ga-asi-vision

  COVID-19 Infects Defense Industry With F-35 Production Slowdown

  Steve Trimble May 27, 2020 This was supposed to be a relatively easy year for Lockheed Martin's F-35 production. As 2020 began, the stealth fighter program's three-year growth spurt had subsided after annual deliveries more than doubled between 2017 and 2019. Lockheed planned to deliver 141 F-35s in 2020, only seven more than in 2019. But the F-35 supply chain is not immune from the global disruption caused by the COVID-19 pandemic. After signaling during a first quarter earnings call in April that a production slowdown was likely, Lockheed confirmed the impact on May 19. The company issued a new forecast of 117-124 F-35 deliveries this year. If Lockheed is unable to recover in the second half, the slowdown would mark the first year-over-year decrease in F-35 deliveries since the program began. “However, we will accelerate production when we return to pre-COVID-19 conditions and could see this number decrease,” the company says. The company's new financial guidance reflects the lower F-35 delivery total, with net sales for the year falling to a range of $62.25-64 billion from $62.75-64.25 billion. Other large F-35 suppliers include Northrop Grumman (center fuselage, radar), Raytheon Technologies (engine, distributed aper-ture system) and BAE Systems (aft fuselage, electronic warfare suite). It was not immediately clear which customers and variants would be affected by the potential shortfall of 18-24 F-35 deliveries in 2020. The Defense Department is closely watching the F-35, its single-largest production system. So far, senior acquisition officials expect the overall impact of the novel coronavirus on weapon system production to be manageable. But the Pentagon leadership considers the military aircraft industry an exception. Although demand and domestic U.S. military spending remain intact, the military aviation supply chain's links to the collapsing commercial aircraft market is causing delays. “I think [military] aviation has had a more acute sensitivity to supplier disruptions, largely driven by the massive upheaval in the commercial aviation market,” said James Geurts, assistant secretary of the Navy for research, development and acquisition. “Many of the aerospace companies were blended between military and commercial, and with commercial just falling through the floor, their abilities to stay open and keep their workforce has been a little bit more challenged.” Another sector Geurts is watching is the market for command, control, communications and computers and intelligence (C4I). “We're trying to track all of it,” he says. “But the most immediate impact we've seen has been on aviation.” Lockheed's F-35 assembly line in Fort Worth was hit hard by the COVID outbreak in mid-April. One employee, Claude Daniels, died after reporting COVID-19-related symptoms to a supervisor. Another F-35 employee, who survived, broadcast a Facebook Live video from his hospital bed, pleading with his unionized co-workers to sanitize their workspaces even if it is not in their job description. The company's management has said that the F-35 assembly line adopted new protocols in response to the COVID-19 pandemic, which included regularly sanitizing equipment and quarantining employees exposed by co-workers or others to the virus. The COVID-19 response is not the only pressure on the F-35's production system. Lockheed exceeded the overall delivery target by three aircraft in 2019, but slower production of the less mature F-35C airframe nearly caused the company to miss the annual goal. To compensate, Lockheed moved up deliveries of four F-35As originally scheduled for 2020 to the end of 2019, allowing the company to beat the delivery target by three aircraft instead of missing it by one. Before the impact of the virus, the F-35's global supply chain was already strained by the three-year production ramp-up from 2017 to 2019. Late part deliveries jumped to 10,000 in 2019 from 2,000 in 2017, according to a May report by the Government Accountability Office (GAO). Monthly parts shortages, meanwhile, leaped to 8,000 in July 2019 from 875 a year before, the GAO says. The shortages represent a fraction of the 300,000 parts in each F-35, but the trend offered a glimpse of the pressure on the supply chain to meet demand during the ramp-up. https://aviationweek.com/defense-space/supply-chain/covid-19-infects-defense-industry-f-35-production-slowdown
