A l'occasion du salon Euronaval On Line, MBDA annonce l'intégration du missile antiaérien Mica NG à son système de défense VL Mica.
MBDA vient d'élargir son système de défense aérienne VL Mica à la version "Nouvelle Génération" (NG) du missile et qui sera disponible en série à partir de 2026. L'intégration du Mica NG est rendue possible par des dimensions externes inchangées malgré un "design entièrement nouveau". Les systèmes actuels pourront être portés au standard VL Mica NG "par de simples mises à jour logicielles". Il intègre par contre "un nouvel autodirecteur infrarouge à base de capteur matriciel offrant une sensibilité accrue et un nouvel autodirecteur électromagnétique avec antenne à émetteurs modulaires actifs (AESA - Active Electronically Scanned Antenna) permettra des stratégies intelligentes de détection", précise MBDA.
Et de poursuivre : "du fait de la réduction de volume de la partie électronique, le MICA NG emportera une quantité de propergol plus importante permettant d'augmenter significativement la portée du missile : un nouveau propulseur à double impulsion permettra ainsi de redonner de l'énergie au missile en fin de vol afin d'augmenter sa manœuvrabilité et sa capacité d'interception de cibles situées à grande distance. En tir depuis la surface, le MICA NG sera capable d'intercepter des cibles au-delà de 40 km. Enfin, la maintenance et les coûts de possession de l'arme seront significativement réduits grâce à des capteurs internes qui permettront de suivre l'état de santé de la munition tout au long de sa vie".
Grâce aux innovations technologiques qu'il intègre, le nouveau système VL MICA NG offre des capacités améliorées pour traiter les cibles atypiques (drones, petits aéronefs), ainsi que pour traiter les menaces futures, caractérisées par des signatures infrarouge et électromagnétique toujours plus réduites. Par ailleurs, les cibles « classiques » (avions, hélicoptères, missiles de croisière et antinavire) déjà traitées par le VL MICA actuel, pourront être interceptées à plus longue distance. "La totale compatibilité entre les deux générations de missiles permettra aux forces armées de les panacher sur leurs systèmes existants et de maximiser ainsi les retombées de leurs investissements", conclut Eric Béranger, président de MBDA.

By: Mike Gruss The Navy plans to test next year whether it can push new software — not just patches but new algorithms and battle-management aids — to its fleet without the assistance of in-person installation teams. Navy officials plan to send the first upgrades to the aircraft carrier Abraham Lincoln's C4I systems for a test in early 2021, officials said during a March 3 media roundtable at the West 2020 trade show in San Diego. Today, Navy teams frequently deliver security patches to ships, but that process does not allow for new capabilities. The reason is because service officials fear that one change to the ship's software could have unintended consequences, creating a cascading effect and inadvertently breaking other parts of the system. But in recent years, Navy officials have embraced the idea of digital twins, which are cloud-based replicas of the software running on a ship's systems. This setup allows Navy engineers to experiment with how new code will react with the existing system. It also helps software developers work on the same baseline and avoid redundancies. Ultimately, the setup offers Navy officials a higher degree of confidence that the software they're uploading will work without any surprises. The Navy completed its first digital twin, the Lincoln, in fall 2019 and has started building a digital twin of the aircraft carrier Theodore Roosevelt. Eventually Navy leaders expect to complete a digital twin of all the service's ships. However, only those in the fleet that have already been upgraded to a certain version of the Navy's tactical afloat network, known as the Consolidate Afloat Networks and Enterprise Services program, or CANES, would be eligible for the over-the-air updates. “In the Information Warfare community, software is a weapon,” Rear Adm. Kathleen M. Creighton, the Navy's cybersecurity division director in the Office of the Deputy Chief of Naval Operations for Information Warfare, told C4ISRNET in a March 17 statement. “If we were to ask a warfighter if it would be valuable to conceptualize, order and receive additional kinetic capability at sea, of course the answer would be yes. The same is true of software. “In an ever-dynamic warfighting environment, the ability to improve, add to, or build new capabilities quickly has extraordinary value. We believe our sailors on the front line are the best positioned to tell us what they need to win. That is what we are trying to accomplish. Put the warfighter's perspective at the center of the software we deliver and do it iteratively at speed.” In this case, think of a capability update for a ship much like downloading a new app on a smartphone. Today, some ships in the fleet can receive security updates for applications they've already downloaded, but they cannot download new applications. Navy officials expect that to change. The new capability would arrive as an automatic, over-the-air update or come pierside, but would not require an installation team as is the case today. “Anytime there's a new capability or a new change, we're just going to do it the same way that you get that done on your smartphone,” said Delores Washburn, chief engineer at the Naval Information Warfare Center Pacific, which is leading the change. “What we will be able to [do] now is do a rapid update to the ships.” Navy engineers hope to be able to push the updates as quickly as war fighters need them. “We're going to try to go slowly here because, again, we're having to tackle simultaneously cultural, technical and operational problems,” said Robert Parker, the deputy program executive officer for command, control, communications, computers and intelligence. The Navy plans to test this new arrangement by installing a set of software, performing an update and then fairly quickly pushing that update to the ship. https://www.c4isrnet.com/battlefield-tech/it-networks/2020/03/19/the-navy-will-test-pushing-new-software-to-ships-at-sea/
