Le Rafale, loin de disparaître, ambitionne de rester le meilleur avion de combat du monde.

PAR

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.

    ‘I’ll be their angel investor’: Air Force vice chief wants to crowdsource airmen’s ideas

    By: Kyle Rempfer As the U.S. military turns its attention to the threats posed by near-peer adversaries, Air Force leadership is shifting its focus to great power approaches to combat, like multi-domain operations and expeditionary warfare. A culture of innovation among airmen will be pivotal in preparing for such a conflict, and the effort to foster that independence and creativity is already underway. In the coming weeks, the Air Force will be rolling out a new initiative to crowdsource solutions from airmen around the service. Across all specialty codes, the service is calling on airmen to design apps, develop algorithms and create new approaches to the problems that plague their career fields or help the Air Force carry out its missions. The program — dubbed the Vice Chief's Challenge — will be spearheaded by Air Force Vice Chief of Staff Gen. Stephen Wilson. “We want to take the ideas our airmen have to see around corners, anticipate what's next and solve these really complex national security challenges,” Wilson told Air Force Times. Those challenges range from fusing open-source social media information into actionable intelligence with new software, to upgrading legacy aircraft with gadgets to help airmen stay in the fight longer. “Navigation apps like Waze change the way we travel across town by giving us an intuitive display that integrates traffic, hazards, and route recommendations in real time. Companies like Uber and Amazon have transformed our view of logistics," according to a copy of the Vice Chief's Challenge provided to Air Force Times. "They are not the only ones leaning forward. I am sure each of you have seen opportunities to enhance [multi-domain operations]. I want to hear your best ideas.” The initiative is designed to deliver capabilities to the Air Force in months, rather than the usual years, Wilson said. And it's going to become routine, always running against the backdrop of the service's other acquisition initiatives. “It's this cultural change and this shift that happens ... and today, I think it's clear in this great power competition, we need this urgently," Wilson said. “I need to remove barriers to innovation." The Vice Chief's Challenge will consist of three phases. First, ideas will be solicited from across the service in a broad announcement. Then, workshops will be set up in which subject matter experts help refine the most promising proposals and draft development plans for the budding ideas. The final phase will involve developing and demonstrating prototypes for the chosen concepts. “We'll start small by gathering ideas from individual airmen, rapidly evolve concepts with national thought leaders, and scale fast by working with industry to build and demonstrate prototypes in the next year,” Wilson said. Each phase will be led by a different organization, but the Air Force Research Lab and the Office of the Vice Chief of Staff will serve as executive agents to ensure smooth transition between phases. The initiative is similar to last year's first-ever Spark Tank innovation proposals. “Each of the [major commands] went out to their different wings and solicited ideas, picked their best ones and came to us," Wilson said. "There were a dozen ideas, of which we picked six of them and presented them at the [Warfighter's Edge] conference.” The idea chosen for development ended up being that of a boom operator on the KC-135 Stratotanker. He proposed a plan to re-engineer the boom operator platform instructor position for the entire KC-135 fleet at a projected cost of $1.5 million. The proposed innovation aims to both reduce back and neck injuries and save the Air Force $132 million each year in this critical aircrew specialty, according to Air Mobility Command. “It was across the fleet, easy to implement, and that's what we're using now,” Wilson said. Other innovative ideas that Wilson has already seen, and clearly wants more of, involve software development that connects sensors, platforms and nodes to share information across the force. “We had an airman and second lieutenant who briefed me on software development they had done that was unbelievable — the capability they were bringing me and the speed at which they were doing it,” Wilson said. The duo took SIPRNet information and found a way to fuse it together using complex computer coding for targeting purposes. The result was a tool dreamed up in-house that directly solved a pressing issue. Much of that is simply owed to the fact that those airmen knew what they needed to do, how to do it and already worked in a position to provide the service. “The CEO of Pivotal [Software Inc.] pulled me aside and said ‘I work with all the Fortune 500 companies across the world, and I would put these two people against any company, anywhere,'” Wilson said. That's the sort of innovation the Vice Chief's Challenge is looking to tap into. Wilson doesn't know yet how many ideas will be taken to completion, but by this time next year, he's hoping that the Vice Chief's Challenge will be handing out some awards. “I can't compensate them like industry can, but I can offer them purpose," he said. https://www.airforcetimes.com/news/your-air-force/2018/09/20/ill-be-their-angel-investor-air-force-vice-chief-wants-to-crowdsource-airmens-ideas

    Russia Researching Future Interceptor Technologies, New Light Fighters

    Piotr Butowski On Jan. 22, Russian state development agency Rostec Corp. published a story on its website about the MiG-31 Foxhound interceptor in which it mentioned that the aircraft's successor, PAK DP or MiG-41, is currently under development. A few days later, the designation MiG-41 was removed from the text. The program for PAK DP, an acronym that roughly translates to Future Air Complex of Long-Range Interception, deserves close attention, as the conceptual work on it has been commissioned and is financed by the Russian defense ministry. The sums allocated to this program so far are small. The PAK DP is a research project, which aims to develop an initial concept of the aircraft and formulate requirements for a subsequent development effort. Available documents show that the main contractor for the PAK DP research work is the United Aircraft Corp. (UAC), which on Dec. 25, 2018, secured a contract from Russia's defense ministry. In May 2019, UAC ordered Russian Aircraft Corp. (RSK MiG) and Sukhoi to develop the aircraft concept. It is not clear whether each company is developing its own concept or if Sukhoi has a section of work under the RSK MiG project. That Sukhoi received the order directly from UAC, and not through RSK MiG, suggests the former. RSK MiG and Sukhoi have commissioned individual parts of the work to subcontractors. In 2020, RSK MiG ordered airborne missile designer and manufacturer GosMKB Vympel to conceptualize arming the PAK DP with air-to-air missiles. At the request of RSK MiG, part of the research work carried out in 2020—though it is not known what work specifically—was undertaken by the Moscow Institute of Thermal Technology (MITT). The engineering school deals with intercontinental and tactical ballistic missiles, as well as hypersonic technologies. Even before the contract from the defense ministry, RSK MiG had requested the Central Aerohydrodynamic Institute (TsAGI) perform tests of the PAK DP model in the T-102 wind tunnel in 2017 and 2018. The T-102 is a low-speed tunnel; the research concerned the characteristics of the PAK DP in various configurations of the wing high-lift devices at speed Mach 0.2 and at angles of attack from -7 deg. to 36 deg. A total of 246 measurements of the model were made. Judging by the meager value of these contracts so far—2.5 million rubles ($33,000) for Vympel, 3 million rubles for MITT and 8.9 million rubles.for TsAGI, the project remains in its early stages. In 2019, as part of the PAK DP program, Sukhoi commissioned the development of instructions for counteracting foreign intelligence. With the launch of any military equipment development program in Russia, an accompanying document is developed in which it is determined what features of the new design must be hidden, as well as ways to hide them—including disinformation. The PAK DP program was broadly referenced by representatives of the Russian aviation industry and the air force in previous years. In August 2017, Ilya Tarasenko, then the director general of RSK MiG, said that PAK DP will implement all the technologies that the company has to offer. In November of that year, Sergey Korotkov, UAC vice president and general designer, said that PAK DP will fight against hypersonic targets. “We will have to deal with hypersonic carriers and their weapons, which are also hypersonic,” Korotkov said. People involved in the PAK DP project have publicly used the designation MiG-41 several times. In the above-mentioned RSK MiG order for PAK DP's wind-tunnel tests, the airplane is called “izdeliye,” or “product” 41. The PAK DP project dates back to the days of the Soviet Union. In the 1980s, MiG was designing MDP, a multifunction long-range interceptor that was developed to achieve a range of 7,000 km (4,350 mi.) while flying at a cruising speed of Mach 2.35. Summing up the available information, it can be said that the purpose of the PAK DP is to fight the most demanding air targets, including hypersonic ones as well as low-orbit spacecraft. The aircraft would also fight against threats similar to those targeted by the current MiG-31, such as heavy bombers and strategic cruise missiles. PAK DP is to achieve the same cruising speed as the MiG-31 at 20 km altitude, Mach 2.35, but with a much longer radius of action. When speaking about the timing of the PAK DP program, UAC President Yury Slyusar said in August 2018 that the creation of the new interceptor “has to be synchronized with exhaustion of the MiG-31's lifetime.” In other words, the 2030s, Slyusar added. For Russia, however, the date is so distant that it is difficult to forecast anything. Current trends in the Russian economy and the aviation industry indicate that Russia will not be able to afford such an aircraft. It is possible that the tasks currently planned for PAK DP will be partially moved to an intercepting variant of the Su-57 fighter, especially after arming it with the new very-long-range missile “izdeliye 810.” In addition, the Russians may again extend the service life and upgrade the current MiG-31 fleet in order to keep it in service well beyond 2030. Light Strike Aircraft, With or Without Pilot RSK MiG, and Sukhoi too undoubtedly, are conducting conceptual work on variants of lightweight tactical combat aircraft. They all have a lower status than the PAK DP project, given there is no procurement or government financing for the variants under study. Sergey Chemezov, the CEO of Rostec, to which UAC, RSK MiG and Sukhoi belong, told reporters in early December 2020 that the corporation is developing the concept of a fifth-generation fighter “in the light- and medium-weight class.” “This could be a universal platform in manned and unmanned versions,” he added. On Dec. 16, 2020, Andrei Yelchaninov, deputy chairman of the Military-Industrial Commission board, told the Izvestia newspaper that “MiG is working on the creation of a light strike aircraft, which can be either manned or unmanned.” Both Chemezov and Yelchaninov underlined that the work “is conducted on an initiative basis and is not funded by the state.” They also emphasized the export orientation of this project and possible cooperation with a foreign partner. One of Russia's possible partners is the United Arab Emirates (UAE). In February 2017, during the IDEX 2017 exhibition, Chemezov announced that Russia and the UAE had agreed to jointly create a new-generation lightweight fighter. Chemezov proclaimed the signing of an appropriate contract later that year. The aircraft would be produced in the UAE and was intended for the UAE Air Force and neighbor services. In the following years, apart from a few general declarations that the project is up to date, details were not available. There are three known acronyms for Russia's new lightweight fighter project. The official strategy of UAC for 2016-2035 was published in December 2016. That document interchangeably uses “LFI,” an acronym translated as Lightweight Tactical Fighter, or “PLIB,” translated as the Future Lightweight Fighter-Bomber, as the names of this program. In 2018, the United Engine Corp. (UEC) said in a presentation that the LFI/PLIB's powerplant could be a single “izdeliye 30” turbofan developed for the Su-57 fighter. According to the same presentation, two modified “izdeliye 30” engines would be used to provide propulsion for the PAK DP. The RSK MiG uses the acronym “LMFS” for its lightweight fighter project. In December 2019, RSK MiG ordered TsAGI to “calculate the aerodynamics of a lightweight multifunction tactical aircraft (LMFS) in a twin-engine configuration” and compare it with foreign counterparts. One of the known RSK MiG LMFS designs is a canard that has a large delta wing, with small control surfaces at the rear and on the sides of the engine nacelles. It has a maximum takeoff weight of 24,500 kg (54,000 lb.) and is designed to reach speeds of up to Mach 2. The ferry range with additional fuel tanks will be 2,160 nm, and the basic weapon load is to be carried inside the fuselage. The current conceptual work on the RSK MiG LFMS is a continuation of the LFI lightweight tactical fighter program launched by MiG as early as 1986. The LFI fighter was later refreshed in the form of the E-721 project for the purposes of the PAK FA stealth fighter program. In 2002, the MiG E-721 lost the PAK FA competition for the Sukhoi T-50 project, the present Su-57. https://aviationweek.com/defense-space/budget-policy-operations/russia-researching-future-interceptor-technologies-new-light
