    THALESRAYTHEONSYSTEMS ET LEONARDO RENFORCENT LEUR COOPÉRATION SUR LES ACTIVITÉS DU SYSTÈME DE CONTRÔLE ET COMMANDEMENT AÉRIEN (ACCS) DE L’OTAN

    MASSY, 10 septembre 2019 - ThalesRaytheonSystems et Leonardo renforcent leur coopération sur l'ensemble du périmètre ACCS. Cette coopération portera sur le soutien du système sur site, le déploiement de l'ACCS sur de nouveaux sites et les rétrofits de sites actuels. Elle permettra aussi de faire bénéficier l'ACCS de plusieurs innovations développées par Leonardo dans le domaine des C2, des communications, des traitements radar et de la défense antimissile balistique. Via cet accord, ThalesRaytheonSystems, Leonardo et leurs partenaires proposeront à l'OTAN et aux opérateurs des Nations membres le meilleur des technologies disponibles sur le marché. Ces nouvelles coopérations vont permettre de gérer de façon plus dynamique et innovante les évolutions d'ACCS. L'ACCS est opérationnel en Italie depuis mars 2015 et le système est en cours de transition dans 10 pays de l'OTAN. La composante anti-missile est opérationnelle depuis 2012 et la composante déployable de l'OTAN est utilisée depuis 2015 dans un certain nombre de pays de l'Alliance. Le système de contrôle et commandement aérien aide les nations membres des pays de l'Alliance à renforcer la souveraineté de leurs territoires, la protection de leurs populations et de leurs forces armées contre toute menace aérienne, y compris les missiles balistiques. Pour les aider à assurer cette mission, ThalesRaytheonSystems développe ACCS, un système unique de commandement et de contrôle aérien unifié et interopérable qui permettra aux pays membres de gérer tous types d'opérations aériennes, tant au-dessus du territoire des pays européens de l'OTAN que lors de déploiements extérieurs. Une fois pleinement déployé, l'ACCS de l'OTAN couvrira 10 millions de km² d'espace aérien. Depuis le début du programme ACCS, plus de 40 entreprises de 15 Nations de l'OTAN ont participé au projet. Leonardo est un partenaire historique fournissant le composant essentiel de fusion des données de plus de 50 types de radars appartenant aux pays membres de l'OTAN. « ThalesRaytheonSystems souhaite renforcer les apports technologiques sur l'ACCS afin de proposer à l'OTAN les dernières innovations de ses partenaires industriels. » Thierry Weulersse, Président-directeur général de ThalesRaytheonSystems « Avant l'ACCS, chaque pays disposait de son propre système. Les membres de l'Alliance bénéficieront bientôt de capacités unifiées qui constituent une véritable révolution en matière d'opérations aériennes. ThalesRaytheonSystems continue d'investir avec ses partenaires pour soutenir l'OTAN dans ses actions et sa transformation. » Thomas Got, Directeur général des activités opérations aériennes et systèmes d'armes de Thales. « L'évolution prévue par ce protocole d'accord est une nouvelle reconnaissance des capacités que Leonardo peut offrir à l'OTAN dans le cadre de l'évolution de l'ACCS vers la défense antimissile aérienne intégrée », a déclaré Manlio Cuccaro, Directeur général adjoint de l'électronique de défense terrestre et navale Italie chez Leonardo. « Leonardo a joué un rôle clé au cours des deux dernières décennies dans la définition et le développement du projet ACCS et nous sommes impatients de renforcer de plus en plus cette relation avec TRS ». https://www.thalesgroup.com/fr/group/press-release/thalesraytheonsystems-et-leonardo-renforcent-leur-cooperation-activites-du

  • Could soldiers silently communicate using brain signals in the future?

    Could soldiers silently communicate using brain signals in the future?

    Andrew Eversden WASHINGTON — A breakthrough in decoding brain signals could be the first step toward a future where soldiers silently communicate during operations. New research funded by the U.S. Army Research Office successfully separated brain signals that influence action or behavior from signals that do not. Using an algorithm and complex mathematics, the team was able to identify which brain signals were directing motion, or behavior-relevant signals, and then remove those signals from the other brain signals — behavior-irrelevant ones. “Here we're not only measuring signals, but we're interpreting them,” said Hamid Krim, a program manager for the Army Research Office. The service wants to get to the point where the machine can provide feedback to soldier's brains to allow them to take corrective action before something takes place, a capability that could protect the health of a war fighter. Krim pointed to stress and fatigue signals that the brain gives out before someone actually realizes they are stressed or tired, thus letting troops know when they should take a break. The only limit to the possibilities is the imagination, he said. Another potential future use is silent communication, Krim said. Researchers could build on the research to allow the brain and computers to communicate so soldiers can silently talk via a computer in the field. “In a theater, you can have two people talking to each other without ... even whispering a word,” Krim said. “So you and I are out there in the theater and we have to ... talk about something that we're confronting. I basically talked to my computer — your computer can be in your pocket, it can be your mobile phone or whatever — and that computer talks to ... your teammate's computer. And then his or her computer is going to talk to your teammate.” In the experiment, the researchers monitored the brain signals from a monkey reaching for a ball over and over again in order to separate brain signals. But more work is to be done, as any sort of battle-ready machine-human interface using brain signals is likely decades away, Krim said. What's next? Researchers will now try to identify other signals outside of motion signals. “You can read anything you want; doesn't mean that you understand it,” Krim said. “The next step after that is to be able to understand it. The next step after that is to break it down into into words so that ... you can synthesize in a sense, like you learn your vocabulary and your alphabet, then you are able to compose. “At the end of the day, that is the original intent mainly: to have the computer actually being in a full duplex communication mode with the brain.” The Army Research Office-backed program was led by researchers at the University of Southern California, with additional U.S. partners at the University of California, Los Angeles; the University of California, Berkeley; Duke University; and New York University. The program also involved several universities in the United Kingdom, including Essex, Oxford and Imperial College. The Army is providing up to $6.25 million in funding over five years. https://www.c4isrnet.com/battlefield-tech/it-networks/2020/11/25/could-soldiers-silently-communicate-using-brain-signals-in-the-future/

  • Adam Smith expects future defense budgets to dip below $716 billion

    Adam Smith expects future defense budgets to dip below $716 billion

    By: Aaron Mehta WASHINGTON — When Congress delivered a $716 billion defense budget to the Pentagon, defense leaders made it clear it was a welcome boost — but some questioned if the number would be enough to do everything the department foresees as necessary. Now the ranking Democrat on the House Armed Services Committee — who is poised to take over the HASC should November elections go blue — is warning that tightened belts are on the horizon. Asked specifically if $716 billion is the right number for defense and whether future budgets will stay at that level, Rep. Adam Smith, D-Wash, said flatly: “No and no.” “I think the number's too high, and its certainly not going to be there in the future,” Smith said at the second annual Defense News Conference. The congressman argued that the debt and deficit situation facing the country requires balancing out how the government is spending, particularly after the Trump administration's tax cuts made it “even more difficult to get our budget under control.” But drawing down the defense budget has to be part of a broader look at U.S. strategy, something that Smith said requires a realistic look at America's military strategy. He pointed to the idea that 355 ships are vital for the Navy as an example of flawed logic, because “capability matters.” “We can do this,” Smith said of the U.S. remaining the key world power. “I'm not even remotely worried about it. It is a more complicated and different world in some ways, but the Cold War was no walk in the park either. World War II certainly wasn't. We will always face challenges. The question is about being smart. “We just have to be smart instead of trying to force our way back into a world that is never going to be again." “We are going to be a major, major player, probably the major player, on the global stage” for a long time to come, Smith added. “But we are not going to be utterly and completely dominant.” https://www.defensenews.com/smr/defense-news-conference/2018/09/05/adam-smith-expects-future-defense-budgets-to-dip-below-716-billion
