  Top Army Official Tests Out Futuristic Smart Combat Glasses

  By Matthew Cox The U.S. Army's new boss recently got a chance do shoot-house training with the latest Microsoft-based, smart soldier glasses. Ryan McCarthy, who is now serving as acting secretary of the Army, and incoming Army Chief of Staff Gen. James McConville traveled to Fort Pickett, Virginia earlier this spring to try out early prototypes of the Integrated Visual Augmentation System, or IVAS. The Army awarded a $480 million contract to Microsoft in November to develop IVAS -- a high-tech device that relies on augmented reality to create a synthetic training environment for soldiers. The experience is reportedly similar to first-person shooter video games. The system is being designed to also be worn in combat, projecting the operator's weapon sight reticle into the glasses. "He and I literally put them on, and we went through a shoot house together," McCarthy told Military.com on a flight to Fort Knox, Kentucky. "Here's the thing -- they are empty rooms, because we had the synthetic feed." McCarthy then described how the IVAS device presented targets that resembled enemy fighters from terrorist groups such as the Islamic State of Iraq and Syria. "I literally came in a room ... and they looked like Taliban targets and ISIS guys with black turbans," he said. "They had one where they had a guy holding a civilian. It looked like a very good video game." IVAS is part of the Army's effort to create a synthetic training world so soldiers can run through many repetitions of combat scenarios, such as clearing urban areas and engaging enemy forces, without having to leave home station and travel to training facilities. Leaders can view the data compiled by IVAS during the training to show soldiers where they need improvement. McCarthy and McConville were joined by Army and Marine Corps sergeants who also took a turn with IVAS. "We had a bunch of NCOs from the 75th Ranger Regiment and the 1st Marine Division, and they did the shoot house and reminded me that I have been out for a while," McCarthy chuckled, referring to the days when he served in the Ranger Regiment. McCarthy served in the Army from 1997-2002. McCarthy acknowledged that these were early prototypes of IVAS that need further development. "You would do it for a little bit, and they would go out and [engineers] had to make a tweak and they would get the screen back up," McCarthy said. Rangers and Marines liked the technology, he said. "The one thing that they all really liked about it was the greater depth perception," he said. "It was like a pair of glasses ... and literally when you are walking through a room and seeing the target, I had depth perception to my left and right, so I could see down the hallway." IVAS replaces the service's Heads-Up Display 3.0 effort to develop a sophisticated situational awareness tool soldiers can use to view key tactical information before their eyes. Officials hope to complete the prototyping phase on IVAS by 2020; when the system might be fielded to soldiers is still unclear. https://www.military.com/daily-news/2019/07/03/top-army-official-tests-out-futuristic-smart-combat-glasses.html

  Florence Parly lance le programme du futur porte-avions français, successeur du Charles-de-Gaulle

  "Je suis fière de lancer officiellement le programme de renouvellement de notre porte-avions", a déclaré mardi Florence Parly au Bourget, lors du salon Euronaval. La ministre des Armées Florence Parly a annoncé mardi le lancement du programme du futur porte-avions de la France, qui succédera au Charles-de-Gaulle, avec une phase d'études de 18 mois, lors du salon du secteur naval de défense Euronaval. Première étape : la phase d'étude. "Le Charles de Gaulle aura besoin d'un successeur (...) C'est pourquoi je suis fière, aujourd'hui, ici, au Bourget, lors de ce salon Euronaval, de lancer officiellement le programme de renouvellement de notre porte-avions", a déclaré Florence Parly. Le montant du projet sera de 40 millions d'euros, a précisé une source gouvernementale. "Cette étape numéro un, qui se lance aujourd'hui, c'est la phase d'étude", a-t-elle précisé. Il s'agit de déterminer "ce que nous voulons et comment nous le voulons pour notre futur porte-avions". La fin du Charles-de-Gaulle prévue autour de 2040. La France dispose d'un unique porte-avions, le Charles-de-Gaulle, qui a vocation à terminer sa vie active autour de 2040. Il subit depuis début 2017 à Toulon une vaste rénovation longue de 18 mois, qui doit lui donner une seconde vie pour les 20 prochaines années. Le Charles-de-Gaulle reprendra ensuite la mer et doit se rendre dans l'océan Indien en 2019. Établir l'architecture du futur porte-avions. La phase d'étude, qui s'achèvera en 2020, doit permettre ensuite d'établir l'architecture du futur porte-avions et de poser les bases de l'organisation industrielle nécessaire pour le b'tir dans les délais et les coûts, a souligné Florence Parly. Cette phase servira à examiner les menaces que le futur porte-avion devra affronter et les missions qu'il devra accomplir, mais aussi son dimensionnement et notamment sa capacité d'accueillir l'avion de combat du futur, le Scaf, lancé en coopération avec l'Allemagne en 2017. La période d'étude permettra aussi d'étudier le mode de propulsion, nucléaire ou classique, de ce porte-avion de nouvelle génération, et les nouvelles technologies qu'il sera capable d'accueillir, notamment les catapultes électromagnétiques, déjà utilisés par la marine américaine. http://www.europe1.fr/politique/florence-parly-lance-le-programme-de-futur-porte-avions-francais-successeur-du-charles-de-gaulle-3785138

  DARPA Awards Six Teams During Final Spectrum Collaboration Challenge Qualifier

  On December 12, DARPA held the second preliminary event of the Spectrum Collaboration Challenge (SC2) – the world's first collaborative machine-intelligence competition to overcome spectrum scarcity. Fifteen teams represented by members from across the academic, commercial and defense landscapes gathered at Johns Hopkins University Applied Physics Laboratory (APL) to pit their intelligent radio designs against each other in a head-to-head competition. At the event's conclusion, six of the eight top-scoring teams walked away with $750,000 each in prize money. While not all competitors received interim prizes, all 15 teams have an opportunity to move on to the next stage and compete in the 2019 Spectrum Collaboration Challenge grand finale, which will be held in conjunction with MWC19 Los Angeles, in partnership with CTIA, on October 23, 2019. The six prize-winning teams from the second preliminary event are: Zylinium, a team of independent researchers MarmotE from Vanderbilt University Sprite from Northeastern University Erebus, a team of independent researchers Gator Wings from University of Florida SCATTER from IDLab, an imec research group at Ghent University and University of Antwerp, and Rutgers University "During the second preliminary event we witnessed a technological shift," said Paul Tilghman, the DARPA program manager leading SC2. "For the first time, we saw autonomous collaboration outperform the status quo for spectrum management." Starting in early December, each team's radio participated in 105 matches against competitors in the Colosseum, a massive RF testbed that was developed specifically for SC2. The matches were held in a round-robin fashion where each radio network – working in groups of threes, fours or fives – had multiple opportunities to compete against every other radio design in the competition. Roughly 400 matches were held in total to determine the final team rankings and the prize recipients. During the PE2 matches, teams were put through six different RF scenarios designed to mimic the challenges that collaborative, autonomous radios will face in the real world. These scenarios challenged the radios to collaboratively mitigate interfering with an incumbent radio system, sense and adapt to the spectrum demands of high-traffic environments, handle the data demands of the connected soldier of the future, and beyond. Each scenario was designed to pressure test various elements of the teams' approaches and, in particular, their ability to successfully collaborate with the other radios operating within the same environment. “The six different scenarios were closely aligned to actual situations that our defense and commercial systems face in the field. The Wildfire scenario, for example, replicates the complex communications environment that surrounds an emergency response situation, while the Alleys of Austin scenario was designed to mimic what's needed to help dismounted soldiers navigate and communicate as they sweep through an urban environment. This real-world relevance was critical for us as we want to ensure these technologies can continue to develop after the event and can transition to commercial and/or military applications,” said Tilghman. The sixth scenario of the competition was used to determine the six prize winning teams. This scenario explored the essential question of the SC2 competition: can the top teams' collaborative SC2 radios outperform the status quo of static allocation? Each of the six teams that received awards at PE2 demonstrated that their radio was capable of carrying more wireless applications without the aid of a handcrafted spectrum plan, while simultaneously ensuring four other radio networks operating in the same area had improved performance. In short, each of these six radio networks demonstrated the autonomous future of the spectrum. To aid with decision making, teams applied AI and machine learning technologies in various ways. Some leveraged the current generation of AI technologies like deep learning, while others used more conventional optimization approaches. There were also a few teams that used first wave, rule-based AI technologies. “We're very encouraged by the results we saw at PE2. The teams' radios faced new and unexpected scenarios but were still able to demonstrate smart, collaborative decision making. PE2 showed us that AI and machine learning's application to wireless spectrum management creates a very real opportunity to rethink our current century-old approach,” said Tilghman. The competition now enters its third year and moves closer to the finale, which will be held at one of the country's largest annual technology and telecommunications shows – MWC19 Los Angeles. More than 22,000 attendees from the broad mobile ecosystem and adjacent industry sectors will convene at this three-day event to discuss the current opportunities and future trends shaping the industry. The SC2 championship event will be held on the keynote stage of MWC19 Los Angeles on October 23, 2019. At the conclusion of SC2's finale, three teams will be awarded $2 million, $1 million and $750,000, respectively, for first, second and third place. The real prize, however, will be the promise of a more efficient wireless paradigm in which radio networks autonomously collaborate to determine how the spectrum should be used moment-to-moment, helping to usher in an era of spectrum abundance.
