An Air Force radio that can run for a week in the sun

The Pentagon has long been looking for a way out from under its tradition of massive, multi-year, multi-billion-dollar projects. With the rapid pace of technological development, military leaders have sought tools and strategies for more rapid acquisitions.

There's the Defense Innovation Unit, or DIUx, a Defense effort to make faster use of emerging technologies. Some organizations have also turned to contractual tools such as the OTA, or other transaction authority, as a means to accelerate the technology buying process.

Recently, technicians at McConnell Air Force Base proved that homegrown ingenuity can make a difference, too. Workers there used a local partnership and a modest development effort to craft a portable, solar-powered communications system.

“The military needs to be ready to go anywhere and solar enables that,” said Tech. Sgt. Clayton Allen of the 22nd Air Refueling Wing.

As a non-commissioned officer in charge of the wing's XPX innovation team, Allen led the effort to shrink down the standard communications package and make it self-sustaining. The three-man team got the job done in about 400 hours, working in cooperation with Wichita State University's GoCreate rapid-innovation lab.

“We took it from a box the size of a small room and made it something you can drag behind you like luggage, weighing about 150 pounds,” he said.

An expeditionary force typically might have to spend a couple of days setting up its communications operation. The newly-developed unit works right out of the box and costs about $12,000 less, the team said. As a solar-power unit, it also does not rely on the presence of a generator, making it easier to deploy in a wider range of circumstances.

“It is completely self-sustainable, powered by solar power, and the solar panel can extend the [battery life] out almost indefinitely,” Senior Airman Aaron Walls, an XPX innovation team member, said in an Air Force news release.

La bataille du futur avion de chasse de l'armée suisse a démarré
La Suisse a lancé début juillet l'appel d'offres pour les nouveaux avions de combat. Les constructeurs Boeing, Airbus, Dassault, Saab et Lockheed Martin redoublent déjà d'efforts pour convaincre la Confédération. Cinq jets doivent être évalués: le Gripen E suédois (Saab), le Rafale français (Dassault), l'Eurofighter allemand (Airbus), et côté américain, le successeur du FA-18, le Super Hornet de Boeing, et le F-35A de Lockheed-Martin. Les constructeurs pourront soumettre leur offre à Armasuisse d'ici la fin janvier 2019. En Suède, l'opération de séduction a démarré à Linköping, petite ville de 150'000 habitants et capitale du Gripen. La localité est habituée aux rugissements du chasseur et au secret défense. Alors qu'il n'était qu'un projet en 2014, le Gripen E de Saab a désormais 30 heures de vols à son compteur. "Le Gripen E mûrit très vite", explique Rustan Nicander, responsable du marché suisse chez Saab. "Le Brésil et la Suède sont déjà clients, avant que la Suisse ne décide d'acheter l'appareil. Ce sera donc un appareil très mûr quand la Suisse fera son choix." Convaincre les politiques et l'industrie Pour remporter à nouveau l'appel d'offres, le constructeur suédois tente de rassurer, tout en misant sur son réseau. "Nous avions déjà remporté la dernière évaluation il y a quelques années", rappelle Jonas Hjelm, responsable des affaires aéronautiques. "Je pense que nous apportons cette fois un ensemble encore plus cohérent." Les performances du futur appareil ne constitueront pas le seul critère pour la Suisse. L'ultra-moderne F-35A américain n'a par exemple plus grand chose à prouver. L'entreprise américaine sait donc qu'elle doit aussi convaincre la politique et l'industrie. "Tous les pays qui ont acheté le F-35 ont eu un retour économique et industriel", affirme Yung A. Le, responsable de l'Europe du Nord chez Lockheed Martin. "Ce ne sera pas différent pour la Suisse. Nous avons des collaborateurs qui rencontrent l'industrie en Suisse romande, chez les Alémaniques et les italophones afin de mieux comprendre le tissu industriel." Après le travail de l'industrie, celui de la diplomatie Les entreprises étrangères avec lesquelles des contrats seront signés devront compenser 100% de la valeur des contrats par des affaires en Suisse. Discrète, la filiale allemande d'Airbus privilégie depuis son bureau bernois les coulisses aux grandes campagnes de communication pour vendre son Eurofighter. "Nous ne sommes pas nouveaux en Suisse, nous y avons déjà des contrats avec l'industrie, mais il faut que nous les développions davantage pour atteindre les besoins demandés", indique le Dr. Alexander-Long Vinh, responsable de cette campagne chez Airbus. Après le travail de l'industrie viendra celui de la diplomatie. Ce sera au gouvernement de chaque constructeur de transmettre une offre à la Suisse. Des tests au sol et en vol seront menés dans le pays entre mai et juillet 2019. Un deuxième appel d'offre pour les jets sera mené en novembre 2019 et les réponses sont attendues pour fin mai 2020. Le choix des modèles devrait tomber vers fin 2020. Le Parlement puis le peuple devraient pouvoir se prononcer sur la facture.

Why the new Raytheon Technologies will eschew platforms for new technology development
By: Aaron Mehta WASHINGTON — “Platform agnostic.” It's a term getting a lot of play from United Technologies CEO Greg Hayes and Raytheon CEO Tom Kennedy, in the wake of this weekend's surprise announcement that the two companies would be merging into a new firm,known as Raytheon Technologies Corporation. Neither company works as a platform producer, eschewing the production of aircraft or ground vehicles and instead focusing on the technology that makes them work. It's a business model that has produced well for both firms, and in a Monday interview with Defense News, the two CEOs made it clear they see no need to deviate now. “One of the first and foremost things we absolutely agree on is, we want to be platform agnostic,” Hayes said, noting that UTC sold off its Sikorsky helicopter unit almost five years ago because “we didn't like the programmatic risk associated with platforms.” “We'll supply all the content and all the systems, all of the offensive, defensive capabilities necessary to make the system successful, but we really think it's important that we remain agnostic among the platform providers,” Hayes added. Said Kennedy, “Neither of us essentially develop platforms or sell platforms. Why that's important is, really, the amount of capital that you have to go and spend in maintaining and creating these platforms kind of takes your eye off the ball relative to investing in technology moving forward. So that was a big feature, that both companies are platform agnostic.” Instead, both men said the new firm will remains focused on developing high-end technologies which can be inserted on, or in, platforms developed by the other major defense primes. With that goal in mind, the company is preparing to spend $8 billion in R&D funds in the year following its merger. When the merger is completed in early 2020, Kennedy will become chairman of the board, with Hayes serving as CEO. Two years later, Kennedy will step down, with Hayes adding the chairman title. One area Kennedy highlighted as having good synergies is hypersonic weapons, a major interest for the Pentagon. Raytheon has already been working on hypersonic missiles, including the guidance and control systems, but UTC's experience with propulsion and materials science might be able to help deal with a specific challenge for Raytheon's weapon designers. “It just turns out when you're flying at Mach 5, you really increase your temperature on all your surfaces," Kennedy said. "If you have a propulsion system, the air is coming in at such a high speed, that creates a significant amount of heat; it has to be dissipated in a very efficient way,” Kennedy said. “And one of the areas that the United Technologies has, really based in the Pratt & Whitney guys, is all the technology that they've developed over the years in working very high temperatures internal to their turbine engines,” he continued. “So not only do they have, I would call it the heat management capabilities, but also the material science to go implement those.” Hayes identified two areas where shared R&D will have a near-term impact, and they underline the benefit of having a new company that will be roughly 50-50 defense and non-defense business. The first is on aircraft control systems, where each company has technologies that can be brought to bear for the FAA's next-generation air traffic control networks. The second comes in the form of cybersecurity. “I think Raytheon is second to none as it relates to cyber, and we view this as a core competency that can benefit the entire commercial aerospace ecosystem,” Hayes said. “Not just the connected aircraft, which is probably the first order of business, but the whole ecosystem. How do you protect passenger data, how do you protect the equipment that's on the ground? How do you protect the airplane while it's flying? “I think we'll see that shortly in the marketplace.” https://www.defensenews.com/industry/2019/06/10/why-the-new-raytheon-technologies-will-eschew-platforms-for-new-technology-development/
