Le temps n'est pas éloigné où les médias français ridiculisaient le Rafale de Dassault Aviation. Ils le présentaient comme une relique invendable et bientôt dépassée d'un temps où la France, dans la tradition gaulliste, voulait avoir des moyens de défense en propre au lieu de tout acheter aux Etats-Unis.
Aujourd'hui le Rafale a finalement fait sa percée à l'exportation avec plus de 144 appareils commandées, dont 96 fermes. Mais il faut aussi prévoir l'avenir. Le 14 janvier, sur la chaîne de montage du Rafale à Mérignac, Florence Parly ministre de la défense a annoncé que le gouvernement voulait lancer les recherches pour une nouvelle version du Rafale, dit au standard F4, pour laquelle un budget de 2 milliards, malgré les restricitons, a déjà été prévu. Par ailleurs les armées françaises comptent augmenter leurs acquisitions à partir de 2022 portant si possible sur cette nouvelle génération du Rafale, livrables entre 2022 et 2030.
Rappelons que le Rafale est le produit d'un ensemble d'industriels comprenant outre Dassault Aviation, Thales, Safran, MBDA-Missile Systems et des dizaines de sous-traitants. Inutile de préciser que chacun d'eux compte réutiliser dans le cadre d'autres produits militaires et civils le savoir-faire acquis.
Le Rafale augmentera ainsi sa supériorité sur ses concurrents européens, Eurofighter et Gripen. Inutile de préciser aussi que dans le même temps les déboires du programme américain F-35 , qui tourne au scandale politique majeur, élimineront la concurrence de ce dernier. Les gouvernements européens qui avaient par complaisance servile avec les Etats-Unis, accepté de s'en équiper, devront vraisemblablement se rabattre sur le Rafale F4. Ils n'y perdront rien.
Quant aux Su-35 et Su-57 russes, en dehors du marché indien où ils tentent de reprendre l'avantage sur le Rafale, ils ne sont en compétition avec lui quasiment nulle part, ce d'autant plus que le Rafale a déjà fait ses preuves dans divers engagements militaires en vraie grandeur, ce qui n'est pas autant que nous sachions le cas pour les russes.
Les innovations du F4 concerneront principalement sa capacité à opérer en fusion de données au sein d'un dispositif interarmes et interarmées. Il sera en mesure, gr'ce à des logiciels opérant par radio, de recueillir et d'échanger des informations en temps réel avec l'ensemble des systèmes d'armes, aériens, terrestres, navals, spatiaux, qui seront engagés sur une zone de guerre. Ainsi navires, troupes au sol, satellites, plateformes aériennes pilotées et non pilotées (UCAV) qui opéreront à ses côtés, pourront bénéficier des échanges avec eux, soit pour être informés de la situation sur le terrain, soit en effectuant certaines missions pour leur compte.
Le F4 sera doté d'un radar amélioré par rapport à l'actuel, dit AESA RBE2, qui pourra être plus précis pour des missions air-sol, plus puissant sur le mode air-air. Par ailleurs les spécialistes ont noté qu'il verra son système d'autoprotection SPECTRA ou Système de Protection et d'Évitement des Conduites de Tir et ses capacités de brouillage améliorées. Son optronique secteur frontal (OSF) sera doté d'infrarouge. Ceci améliorera les performances nocturnes de l'appareil jusqu'ici réduit à un capteur TV pour l'identification et la poursuite des objectifs aériens.
Ajoutons que Thales apportera sur le F4 ses savoir-faire en matière de gestion des données en temps réel (Big Data) et d'intelligence artificielle (IA) pour offrir au F4 des outils de maintenance prédictive qui devraient permettre non seulement de réduire significativement le coût du maintien en condition opérationnelle mais aussi de rehausser le taux d'appareils immédiatement disponibles, qui ne dépasse pas actuellement du fait des nécessités de la maintenance environ 60%.
On peut penser que le F4 sera est une nouvelle étape vers un Rafale F5, ou MLU (Mid-Life Upgrade), qui verra la pérennité de la filière pilotée assurée au-delà de l'horizon 2050, malgré les prédictions hasardeuses selon lesquelles les appareils pourront se passer de pilotes à bord.
Enfin le Rafale F4 pourra emporter le missile AS4NG (air-sol nucléaire de quatrième génération), missile hypersonique capable de voler à plus de 5.000 km/h et devant entrer en service à l'horizon 2035. Il pourra ansi rivaliser avec les missiles hypersoniques dont seront seuls dotés la Russie, la Chine et sans doute les Etats-Unis, lesquels s'efforcent actuellement de rattraper leur retard en ce domaine.
Il faut espérer que les futurs gouvernement français ne remettront pas en cause ces programmes, dans le désir de mieux financer la consommation ou de se conformer à des instructions de l'Otan.

By Warren Duffie Jr., Office of Naval Research Public Affairs ARLINGTON, Va. (NNS) -- In an effort to establish new connections with innovative small businesses and research companies—and reach these players where they live and work—the U.S. Navy will host a trio of outreach events on April 8-11 in Lowell, Massachusetts. The Navy will hold the events through its Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, both located at the Office of Naval Research. SBIR provides the Navy with groundbreaking technology created by small firms—while STTR transitions products developed by both small businesses and research institutions to the Navy and Marine Corps. This year's events will spotlight New England's regional technology corridor, known for its prominent academic institutions, research centers, laboratories and science- and defense-focused companies. “Outreach events like these help foster collaboration to enhance the innovation network and pipeline, and accelerate the delivery of needed technologies to the Navy and Marine Corps,” said SBIR Director Bob Smith. “It's part of a new naval effort to deliver capabilities to warfighters faster by expanding relationships with regional technology hubs. This year, New England is the first stop.” The three events are: Partnering Summit—This is a setting where the naval acquisition community, government, industry and research organizations can meet to discuss naval priorities, share best practices and learn about partnership opportunities with SBIR and STTR. Monday, April 8, and Tuesday, April 9, at the UMass Lowell Inn & Conference Center. Learn more at https://www.onlineregistrationcenter.com/SBIRSTTR. Navy Forum for SBIR/STTR Transition (FST)—FST is an annual innovation marketplace matching Navy needs with small business-technology solutions. Attendees can see 133 exhibits from 107 vendors; engage in one-on-one meetings; listen to Tech Talks; and sit in on sessions hosted by congressional and Department of Defense leaders. Wednesday, April 10, and Thursday, April 11, at the Tsongas Center at UMass Lowell. Learn more at https://navyfst.com/. Accelerated Delivery and Acquisition of Prototype Technologies (ADAPT) Workshop—ADAPT is a new approach to match non-traditional small businesses with naval needs and quick research-and-development funding. This half-day workshop will feature technology briefs on pre-released areas of interest from a Navy shipyard; discussion about the proposal process and contracting; and opportunities for face-to-face conversations with subject matter experts. Wednesday, April 10, from 8 a.m. to noon. UMass Lowell Inn & Conference Center. Learn more at https://www.onlineregistrationcenter.com/ADAPT. https://www.navy.mil/submit/display.asp?story_id=108981

By C. Michaela Judge, Naval Information Warfare Center Atlantic Public Affairs CHARLESTON, S.C. (NNS) -- The Land Systems Integration (LSI) Division at Naval Information Warfare Center (NIWC) Atlantic continues to be an enterprise leader in Model-Based Systems Engineering (MBSE) for their work on land systems modernization and integration. MBSE is an engineering approach that utilizes a common, digital tool suite allowing all team members – from engineer to sponsor – to have awareness, line-of-sight and an understanding of the interaction between the various moving parts across the systems engineering and project lifecycle. LSI's Vehicular Technology Transition (VTT) team incorporates the full range of MBSE techniques into their systems engineering projects to support the Marine Corps and has had great success in continuing this approach in their daily work. “What makes LSI and our team specifically successful is the depth of knowledge in implementation of using the MBSE Tool Suite,” said Tim Turner, VTT team lead. “Our engineering work isn't radically different than any other engineering groups across the Command; it's how we're putting the data in the system and making it transparent to everyone that needs to have access to it.” Though engineers have been performing systems engineering in some capacity for decades, using this model-based approach provides an added advantage to deliver effective and timely solutions to the warfighter. “Our MBSE Tool Suite is a set of seamlessly integrated engineering lifecycle management tools that work together as one,” said Jacob Witmer, VTT team Military GPS User Equipment (MGUE) project lead. “We use these tools to manage requirements and architectures, plan projects, track changes, manage quality, and provide an enterprise library management system where you catalog, organize, use, reuse, manage, and report on any type of software, technology, or business asset.” In the vehicle transition domain, the VTT team utilized MBSE techniques to solve real-world challenges for the warfighter. Most recently, they used MBSE to conduct global positioning system (GPS) integration work conducted on the Joint-Light Tactical Vehicle, the MGUE Program's lead platform. “When we look at all of the people our team has to work with on this integration project, we have to manage a lot of different data, to include where the trucks are manufactured, where GPS is managed, the performance level of the GPS card, the truck integration and more,” said Witmer. “There are a lot of players, managing a lot of data in a lot of different formats from different geographic parts of the country. That's really what the MBSE Tool Suite is designed to do – manage, connect and link the data to see how they impact each other.” One cost-avoidance benefit of using the MBSE Tool Suite, in time and man-hours, includes the ability to quickly build reports. “We can build 150-page project requirements documents in three minutes because the data is already in the Tool Suite,” said Ryan Longshore, VTT team technical lead. “There is an investment in time and energy upfront in loading the data, but a report that would take 30 to 90 days is done in a matter of minutes and everything from that project is captured in the report.” The team's use of MBSE is not only essential to connecting and maintaining data across a project, but also a necessary resource in developing physical models and solutions in a fraction of the time previously needed to fulfill a warfighter requirement. “Our team works within the Systems Integration Laboratory (SIL) to design and test on multiple vehicular platforms,” said Turner. “The lab allows us to execute MBSE across all team functions, from mission thread to risk analysis or program management.” The team maintains physical models for all of the vehicle platforms they support. When a requirement from a sponsor arrives, the team can use tools within the SIL to design and print a three-dimensional piece of hardware and test it on an existing model before they touch a physical vehicle. The team conducts engineering, mechanical and software-related integration testing and design work all within the laboratory. “It's all about testing upfront, learning upfront, failing faster and learning from it and moving on and improving on the design,” said Turner. As the team designs and tests within the lab, they also update the MBSE Tool Suite is to capture lessons learned, integration challenges and real-time project data for all team members to access. “The beauty of the suite being so integrated is that it doesn't matter what type of systems engineering methodology a project uses, the tools can be tailored to meet a myriad of engineering processes and organizing the data by methodology saves countless hours in digging around trying to find historical artifacts,” said Witmer. The team can now complete an integration project that previously took 18 to 36 months as quickly as six to nine months, without sacrificing quality, thanks to the value of MBSE. With VTT and other teams reaping the benefits of MBSE, NIWC Atlantic created a training and workforce development path to work toward a Command-wide adoption of this method. Communities of interest, industry engagements and training events on MBSE methods are a few of the efforts implemented to date. The VTT uses these training approaches, to a smaller-scale, to continue to encourage MBSE implementation and help employees understand the power of using a model-based approach to apply agility in executing warfighter solutions. “We're seeing the benefits and through MBSE my team has the flexibility to fail fast and learn a lot upfront,” said Turner. The team's success with the MBSE Tool Suite is a Command-wide example of how the transparency and connectivity of engineering data help to provide integration solutions to NIWC Atlantic customers with a high confidence of success. As a part of Naval Information Warfare Systems Command, NIWC Atlantic provides systems engineering and acquisition to deliver information warfare capabilities to the naval, joint and national warfighter through the acquisition, development, integration, production, test, deployment, and sustainment of interoperable command, control, communications, computer, intelligence, surveillance, and reconnaissance, cyber and information technology capabilities. https://www.navy.mil/submit/display.asp?story_id=110447
