La Navy débarque le Hornet alors que le Super Hornet marque des points

Boeing, qui a pris le contrôle du programme F/A-18 en rachetant McDonnell Douglas, peut-être satisfait : alors que l'US Navy retire ses derniers F/A-18 Hornet des unités de première ligne, son successeur, le Super Hornet, reste bien présent sur le marché des avions de combat où il tient tête (Canada, Finlande, Allemagne...) au F-35 de Lockheed [...](...)

    DoD Creating Standards For AI Programs

    DoD has "so many hundreds of programs that we really couldn't do a fair evaluation of each individual activity," Mark Lewis, director of modernization in the Research and Engineering office, said today. By THERESA HITCHENSon May 19, 2020 at 5:05 PM WASHINGTON: DoD's Research and Engineering (R&E) office has launched a new initiative to develop best practices for the many programs to design and build artificial intelligence (AI) applications, says Mark Lewis, director of modernization. AI is one of DoD's top research and development priorities, charged to the Director of R&E Mike Griffin. The standards initiative is the brain child of newly appointed AI technical director Jill Chrisman, Lewis told the virtual “Critical Issues in C4I Conference 2020,” sponsored by AFCEA and George Mason University. “When Jill first joined us just a couple of weeks ago, I asked her to give me a site view of all the efforts underway in AI across the department, and kind of give me an evaluation of where we stood,” Lewis explained today. However, he said, because DoD has “so many hundreds of programs that we really couldn't do a fair evaluation of each individual activity.” So, instead R&E has decided “to establish a series of standards, if you will, principles and practices that we consider to be good practices for artificial intelligence engineering,” he said. “I liken it to systems engineering.” A key goal of the new effort is to break down stovepipes in order to allow the various DoD AI efforts to share databases and applications. In addition, Lewis said, R&E is aiming to “figure out what are the artificial intelligence applications that will have the biggest impact on the warfighter.” This could involve moving out prototypes rapidly so that warfighters have an opportunity to “play with them, experiment with them, and figure out what makes their job more effective,” he added. At the same time, it would enable warfighters to quickly reject things that are not useful or overly complicated. Lewis said that developing autonomous systems is another top priority. That portfolio of effort is handled by assistant director Wayne Nickols, and is focused on development autonomous systems that can team seamlessly with humans. “We want autonomy systems that will operate in ways that put human life at lower risk,” he explained. “If we can if we can have a robotic system as a target, instead of a human being as a target, that's that's our preferred approach.” In his wide-ranging discussion, Lewis also expounded on DoD's research goals for quantum science — a focus area that he said is somewhat less well developed than others on DoD's high priority list. “There is a lot of hype associated with quantum science,” he said bluntly. “People are talking about quantum computers that will, in a few years, replace our fastest supercomputers, quantum communication technology, quantum key encryption techniques. And frankly, a lot of it is promising — but it's also very very far term.” That said, Lewis noted that there are two near-term opportunities for DoD in the field: enabling back-up positioning, navigation and timing capability in case GPS satellites are degraded in anyway; and future “exquisite sensors for a variety of applications.” https://breakingdefense.com/2020/05/dod-creating-standards-for-service-ai-programs/

    AeroVironment Introduces Extended Range Antenna, Expanding UAS Command and Control up to 40 Kilometers in a Lightweight, Portable Form Factor

    • Cost-effective optional antenna array kit designed to integrate seamlessly with AeroVironment's standard RF head antenna • Provides operators 100 percent greater controllable range over standard RF head antenna with minimal logistical footprint • Add-on kit narrows antenna beam width, extending command and control range up to 40 km SIMI VALLEY, Calif., Dec. 10, 2020 – AeroVironment, Inc. (NASDAQ: AVAV), a global leader in unmanned aircraft systems (UAS), today announced the introduction of its Extended Range Antenna (ERA), the latest addition to AeroVironment's growing line of network connectivity solutions. The ERA is a lightweight, portable antenna array kit designed to integrate seamlessly with AeroVironment's standard RF head antenna to support a diverse range of missions. The ERA add-on kit narrows the antenna beam width, extending the command and control range up to 40 kilometers (24.9 miles) with minimal impact to its size, weight and power (SWAP) footprint. Similar to the standard RF head antenna, the ERA is manually positioned. The included RF Unit switch allows users to toggle between omnidirectional mode, for short-range operations, and extended range mode, for longer-range operations. The ERA supports both M1/2/5 and M3/4/6 Digital Data Link (DDL) operating bands. By adding the ERA kit to their existing AeroVironment RF antenna, UAS flight operators can immediately expand their operational capabilities, gaining actionable battlefield intelligence at greater stand-off range to maximize their stealth and safety. When used in combination with other AeroVironment network connectivity options, the ERA provides an enhanced level of operational flexibility. This enables teams to coordinate command and control transfer of UAS, such as Puma LE, easily over greater distances, maximizing the aircraft's multi-mission capabilities, in day or night operations, across dynamically changing environments. “AeroVironment continues to incorporate direct customer and user feedback into our product development investments to address increasingly complex and dynamic mission requirements,” said Rick Pedigo, AeroVironment vice president of sales and business development. “Not only do operators benefit from available options in terms of UAS capabilities, but they can also benefit from a selection of antenna options that are portable, easy to operate and provide extended range and multi-mission capabilities.” Further expanding its connectivity solutions, AeroVironment recently announced updates to its Long Range Tracking Antenna (LRTA), which it now offers in two versions to support M1/2/5 and M3/4/6 DDL frequency bands. AeroVironment's network connectivity product line includes the pocketable, short-range pDDL (5 km), standard RF antenna (20 km), ERA (40 km) and LRTA (60 km) capabilities in both M1/2/5 and M3/4/6 bands.

    US warns EU against defense market protectionism

    BRUSSELS (AP) — The United States is warning the European Union not to use its deepened military cooperation as an excuse to protect Europe's defense industry, saying such practices could undermine NATO. The U.S. ambassador to NATO, Kay Bailey Hutchison, said Tuesday that "we do not want this (cooperation) to be a protectionist vehicle for EU." She said Washington is "going to watch carefully because if that becomes the case then it could splinter the strong security alliance that we have." EU leaders — 22 of whose nations are also members of the U.S.-led NATO alliance — agreed last year to jointly develop or purchase military equipment like drones. Washington is concerned the bidding process might exclude U.S. firms. http://www.businessinsider.com/ap-us-warns-eu-against-defense-market-protectionism-2018-2
