    US Army picks 5 teams to design new attack recon helicopter

    By: Jen Judson WASHINGTON — AVX Aircraft Co. partnered with L-3 Communications Integrated Systems, Bell Helicopter, Boeing, Karem Aircraft and Lockheed Martin-owned Sikorsky have won awards to design a new Future Attack Reconnaissance Aircraft (FARA) for the U.S. Army over the next year, the service announced April 23. Only two teams will move forward, at the end of the design phase, to build flyable prototypes of the future helicopter in a head-to-head competition. The Army laid out a handful of mandatory requirements that the vendors had to meet and also a list of desired requirements for initial designs, Col. Craig Alia, the Future Vertical Lift Cross Functional Team chief of staff, told a select group of reporters just ahead of the contract awards. The service also looked at the vendors' execution plans and evaluated timing as well as funding profile requirements. “The ones that were selected were clearly meeting the mandatory requirements and were in the acceptable risk level of the execution plan and the desired requirements," Dan Bailey, who is the FARA competitive prototype program manager, added. The prototype program falls under the purview of the Army Combat Capabilities Development Command Aviation and Missile Center's Aviation Development Directorate. AVX and L3 unveiled its design for the FARA competition at the Army Aviation Association of America's annual summit in Nashville, Tennessee, earlier this month. The design uses AVX's compound coaxial and ducted fans technology. The companies said its single-engine design meets 100 percent of the Army's mandatory requirements and 70 percent of its desired attributes. The CEO of Textron, Bell's parent company, said during a recent earnings call, that its FARA design will be based on its 525 technology rather than its tiltrotor technology. Bell has built and flown a tiltrotor prototype — the V-280 Valor — for the Army's Future Vertical Lift program. Karem has been working to develop technology under a small contract to help build requirements for FVL aircraft focused on a medium-lift helicopter. Sikorsky's offering will be based off of its X2 coaxial technology seen in its S-97 Raider and the Sikorsky-Boeing developed SB-1 Defiant, which are now both flying. “This is the culmination of years of investment in the X2 Technology Demonstrator and the S-97 RAIDER aircraft that have proven the advanced technology and shown its ability to change the future battlefield,” Tim Malia, Sikorsky's director of Future Vertical Lift Light, told Defense News in an emailed statement shortly after the announcement. “We continue to fly the S-97 RAIDER to inform the design for FARA, which provides significant risk reduction to the program schedule and technical objectives. We are eager to continue to support the US Army, and we are excited that the Sikorsky FARA X2 will be ready for this critical mission," he said. A total of eight teams submitted data and potential designs for FARA, but upon evaluation, three of those did not meet mandatory requirements, according to Bailey. It is not publicly stated who the losing teams were, but MD Helicopters had previously protested the Army's decision to not enter into a first phase agreement with the company to develop a FARA prototype, arguing to the Government Accountability Office (GAO) that the Army “unreasonably” evaluated its proposal and failed to promote small business participation. The GAO denied the protest earlier this month on the grounds it did not have authority to review protests of contracting mechanisms like Other Transaction Authorities (OTA) which the Army used in this case. The awards were made two months ahead of an already ambitious schedule to get FARA prototypes flying by 2023. A production decision could happen in 2028, but the service is looking at any way possible to speed up that timeline. The Army has to move quickly, Alia said. Echoing his boss, Brig. Gen. Wally Rugen, the FVL CFT director, he said the Army is “at an inflection point. We can't afford not to modernize. We know the current fleet is fantastic, but we can't indefinitely continue to incrementally improve 1970s to 1980s technology.” FARA is intended to fill a critical capability gap currently being filled by AH-64E Apache attack helicopters teamed with Shadow unmanned aircraft following the retirement of the OH-58D Kiowa Warrior helicopters. The service has tried and failed three times to fill the gap with an aircraft. The Army is also planning to procure another helicopter to fill the long-range assault mission, replacing some UH-60 Black Hawk helicopters in the fleet, simultaneously. With the advent of the new Army Futures Command — that is focused on six major modernization priorities of which FVL is third — the service is moving faster on prototyping capability to ultimately procure major weapon systems at a somewhat unprecedented speed. Through the AFC and the use of contracting mechanisms like OTAs, the Army has found a way to compress parts of the acquisition process that previously took three to five years into periods of time often amounting to less than a year. “What is exciting about the new process the Army has put in place,” Bailey said, “in basically a year's period of time, we've gone through concept, through an approved set of requirements, to developing an innovative approach to contracting, to building industry partnerships to have industry propose to us a plan and a solution.” And the Army rigorously evaluated those FARA proposals, Bailey said, all within that year. The teams have until January or February next year to provide design plans and an approach to executing the build of the prototypes followed by potential larger-scale manufacturing, Bailey said. The second phase of the program will be to build prototypes, and “only two will make it into phase 2 and they all know that now,” Bailey added. According to Rugen, when the request for proposals was released, the Army did not want to get locked into keeping inflexible requirements, but the request did state that the aircraft should have a maximum 40-foot rotor diameter. The Army also asked for the aircraft to be able to accept some government furnished equipment including an engine, a gun and a rocket launcher, Alia said. When it comes to some of the desirable attributes for a new aircraft, the Army is considering speed, range and payload possibilities, Alia said, but the service “wanted to encourage innovation by industry to come to us with their ideas and unique ways of meeting both mandatory and desirable characteristics and that is where we got some great feedback from industry and some innovative designs.” https://www.defensenews.com/digital-show-dailies/aaaa/2019/04/23/us-army-picks-5-teams-to-design-new-us-army-attack-recon-helicopter/

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

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

    PAR JEAN-PAUL BAQUIAST 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. https://blogs.mediapart.fr/jean-paul-baquiast/blog/190719/defense-le-rafale-f4
