La DGA commande un prototype de laser anti-drones à Cilas

La Direction générale de l'armement (DGA) a annoncé, mercredi 15 juin, avoir passé commande auprès de la PME Cilas, basée à Orléans (Loiret). La DGA indique avoir attribué à Cilas le marché L2AD, qui prévoit notamment l'achat d'un prototype opérationnel de système laser capable d'identifier, poursuivre et neutraliser des micro-drones (de 100g à 25kg). Le système Helma-P, développé par Cilas, dispose d'une puissance de deux kilowatts, peut détecter un appareil à trois kilomètres de distance et le neutraliser à moins d'un kilomètre, même lorsque sa vitesse dépasse les 50 km/h. Le laser peut également éblouir le drone, en saturant ses capteurs optiques. Une technologie que compte utiliser le ministère des Armées « afin notamment de renforcer la protection des sites militaires sensibles et des opérateurs d'importance vitale », précise le communiqué. D'un montant maximal de 10 M€, ce contrat s'inscrit dans un programme plus vaste de lutte anti-drones, pour lequel les armées prévoient d'investir 300 M€ sur 10 ans.

    US Navy supercarrier John C. Stennis is headed for a complex overhaul

    By: David B. Larter WASHINGTON — Huntington Ingalls Newport News is gearing up to start a yearslong overhaul of the U.S. Navy carrier John C. Stennis, which is shifting home ports from Washington state to Norfolk to get ready for its break from the rotation. The company announced last week it had inked a $187.5 million contract for advanced planning to support Stennis' refueling and complex overhaul, or RCOH, slated to begin in 2021. The contract is for “engineering, design, material procurement and fabrication, documentation, resource forecasting, and pre-overhaul inspections,” according to the announcement. In a statement, HII's head of carrier maintenance said the contract was a critical first step toward getting Stennis started out right.

    Australia to buy U.S. Tomahawk missiles to boost long-range strike capability | Reuters

    Australia will spend A$1.3 billion ($833 million) to boost its long-range strike capabilities as it finalised on Monday a deal to buy more than 200 Tomahawk cruise missiles from the United States, part of a wide-ranging defence shake-up.

  • The Air Force’s experimental navigation satellite cleared for fabrication

    The Air Force’s experimental navigation satellite cleared for fabrication

    Nathan Strout WASHINGTON - The U.S. Air Force has completed critical design review of an experimental navigation satellite, clearing the way for fabrication to begin and keeping the launch on track for 2022. The Air Force Research Laboratory's Navigation Technology Satellite 3 (NTS-3) is one of the Air Force's first Vanguard programs — platforms that can delivers remarkable new capabilities to the war fighter. NTS-3 is being developed to demonstrate new positioning, navigation and timing (PNT) technologies that will inform how future GPS satellites work. AFRL plans to operate the satellite in geosynchronous orbit for one year to experiment with new PNT signals and test new architectures. Beyond the space-based test vehicle itself, NTS-3 will also demonstrate new ground-based command and control as well as new software-defined radios. And, once on orbit, NTS-3 could provide immediate support to the war fighter. The experimental satellite will augment the GPS constellation from geosynchronous orbit, providing a geographically focused signal. “The NTS-3 Vanguard is an experimental, end-to-end demonstration of agile, resilient space-based positioning, navigation, and timing,” Arlen Biersgreen, the NTS-3 program manager, said in a statement. “It has the potential for game-changing advancements to the way the Air Force provides these critical capabilities to war fighters across the Department of Defense.” L3Harris is the prime contractor on NTS-3, and was awarded an $84 million contract for the experimental satellite in 2018. With the critical design review complete, the company can now move forward with fabrication, demonstration and testing. The NTS-3 contract includes a follow-on option for production of an entire constellation, if the Air Force chooses to exercise it. “Collaboration with our customers has enabled us to move rapidly through important milestones to design this experimental satellite,” said Ed Zoiss, president of space and airborne systems at L3Harris. “Our goal is to deliver new signals to support rapidly evolving warfighter missions.” Due to scheduling, NTS-3 technology is unlikely to be included on the any of the GPS III satellites in production, but it will likely inform aspects of the subsequent GPS IIIF satellites which are set to go on orbit in the late 2020s. L3Harris is developing the payloads for those satellites as well. https://www.c4isrnet.com/battlefield-tech/space/2020/08/04/the-air-forces-experimental-navigation-satellite-cleared-for-fabrication
