MELBOURNE, Australia — Japan has named Mitsubishi Heavy Industries as the prime contractor to build its next-generation fighter jet, with the Defense Ministry announcing earlier Friday that it signed a contract with the company.
“We will steadily proceed with the development of the next fighter (F-X) together with the company,” the ministry said in a brief statement posted on it website.
Local media is reporting Defense Minister Nobuo Kishi said the country will select an overseas partner by the end of this year for collaboration on aircraft technology, with stealth technology being one area of focus.
The selection of MHI as the prime contractor for the F-X program comes as little surprise, given Japan was determined to restart its indigenous fighter aircraft capabilities. The company is the only one in Japan with experience in this area. The firm took the 21st spot on Defense News' most recent ranking of the top 100 defense companies in the world.
Reuters previously reported the contract for the aircraft is worth up to $40 billion. Defense News emailed the Defense Ministry's Acquisition, Technology and Logistics Agency for an update on the contract value but did not receive a response by press time.
The Defense Ministry is also seeking more funding for F-X research and development in its latest budget request submitted to the country's Finance Ministry in late September. The Defense Ministry requested $555.8 million for the main program and an additional $113.6 million for R&D of fighter subsystems, such as radars and mission systems integration.
The funding will allow Japan to continue its R&D work into fighter technology, which it has kept up over the past decade despite the end of production on the Mitsubishi F-2 fighter jet and the decision to buy the Lockheed Martin F-35.
Work the country plans to continue includes the development and refinement of stealth designs and materials, active electronically scanned array radars, and afterburning turbofan engines. Toward that end, local engine manufacturer IHI is expected to continue work on its XF9-1 afterburning turbofan.
Japan conducted a series of test flights of a locally designed and built fighter technology demonstrator from 2016 to 2018 to validate its work. The country used the data gleaned from the test program to further refine its indigenous capabilities.
The ministry previously said it wants to launch the basic design process for the F-X airframe and engine before the end of the current Japanese fiscal year, which ends March 31, 2021. This would be followed by the production of the first prototype, which is planned to begin in 2024, with flight tests earmarked to start in 2028 following finalization of the design and production plans.
Japan plans to replace its fleet of approximately 90 F-2 jets with the new fighter jet starting around 2035. The F-2 was developed in conjunction with Lockheed in the 1990s, and resembles a larger version of the American company's F-16 multirole fighter but is primarily equipped with indigenous systems.
Japan also plans to acquire 147 F-35s, which will include 42 of the short-takeoff-and-vertical-landing variants. That version, the F-35B, will operate from a pair of helicopter destroyers currently undergoing modifications to handle the jet.
Japan also recently selected Boeing to upgrade 98 of its license-built Mitsubishi F-15J/DJ Eagle interceptors that will see the jets fitted with newer radars and integrated with standoff land-attack missiles.

SOURCE: FLIGHTGLOBAL.COM, BY: GARRETT REIM After completing static, drop and durability testing on the F-35A, Lockheed Martin believes that early results indicate potential for an increased service life certification of the stealth fighter. The F-35's service lifetime is designed to be 8,000h, but each test airframe is required to successfully complete two lifetimes of testing, the equivalent of 16,000h. The F-35A exceeded the requirement by completing three full lifetimes of testing, 24,000h, prompting Lockheed to moot the potential service-life extension. “We look forward to analyzing the results and bringing forward the data to potentially extend the aircraft's lifetime certification even further,” said Greg Ulmer, Lockheed Martin's vice president and general manager of the F-35 program. “Already certified for one of the longest lifetimes of any fighter, an increase would greatly reduce future costs for all F-35 customers over several decades to come.” The USAF plans to fly the F-35A until at least 2070, so a longer lifespan per aircraft may allow the service to reach that goal without having to purchase new fighters. However, as aircraft age they become more expensive to maintain and operate, making it unclear if a service life extension of the F-35A would be economical. The F-35A airframe completed its testing at BAE Systems in Brough, England. The F-35B and C variants were tested at Lockheed Martin's facility in Fort Worth, Texas, though the company did not release the results for those variants. All variants will eventually undergo final teardown inspections at the National Institute for Aviation Research in Wichita, Kansas. https://www.flightglobal.com/news/articles/f-35-stress-tests-raise-possibility-of-longer-servic-451964

Posté dans Technologie par Laurent Lagneau Alors que l'industrie française de l'armement cherche à limiter autant que possible le recours à des composantes relevant de la Réglementation américaine sur le trafic d'armes au niveau international [ITAR] afin d'éviter toute restriction à l'exportation, il aurait été dommage de voir l'entreprise iséroise Dolphin Integration, spécialisée, avec ses 130 ingénieurs, dans la conception de circuits intégrés et de composants dits virtuels analogiques et numériques, fermer ses portes. D'autant plus que cette PME, créée en 1985, avait été sélectionnée par l'Agence européenne de défense [AED] dans le cadre du programme SOC – System on Chip [.pdf], visant à permettre aux industriels européens de l'armement d'accéder à des technologies « ITAR Free » pour « des petits et moyens volumes à des prix compétitifs. » En outre, elle a mené des projetspour le compte de la Direction générale de l'armement [DGA], via le dispositif RAPID Or, en juillet, faisant face à d'importants problèmes de trésorerie et à un chiffre d'affaires en recul, Dolphin Integration a été placé en redressement judiciaire. Et l'entreprise avait jusqu'à la mi-janvier 2019 pour trouver une solution pour assurer la poursuite de ses activités. Cette mésaventure lui est arrivée alors qu'elle avait l'ambition de devenir un acteur mondial de « la conception et de l'optimisation de circuits intégrés dédiés à la très faible consommation d'énergie » et de s'intéresser aux marchés de l'Internet des objets (IoT), de l'automobile et de la défense. Mais il n'aura pas fallu attendre bien longtemps pour voir la situation de Dolphin Integration s'éclaircir étant donné que le missilier MBDA et Soitec, le spécialiste français de la production de matériaux semi-conducteurs, se sont associés pour reprendre la PME iséroise. Dans le détail, le capital de Dolphin Integration sera détenu à hauteur de 40% par MBDA et de 60% par Soitec. Les deux industriels ont pris l'engagement d'investir 6 millions d'euros ensemble. De quoi permettre d'acquérir « la plupart des actifs de Dolphin Integration », de payer « certaines dettes » et d'opérer une « importante injection de liquidités destinée à financer les besoins en fond de roulement. » Étant déjà un client « stratégique » de Dolphin Integration pour les « applications liées à l'armement depuis 2004 », MBDA va accentuer la coopération industriel avec la PME tout en lui « offrant une perspective commerciale à long terme en matière de circuits ASIC (circuits intégrés propres à une application spécifique) et systèmes sur puces. » « L'investissement de MBDA va renforcer la base industrielle de Dolphin Integration dédiée à l'armement français. Il va en effet lui apporter une source plus stable de revenus liés à la défense ainsi qu'une coopération technologique plus étroite ouvrant à son offre microélectronique spécialisée l'accès à l'ensemble de l'industrie de l'armement française et européenne », a expliqué Antoine Bouvier, le Pdg du missilier. http://www.opex360.com/2018/08/24/missilier-mbda-soitec-reprennent-dolphin-integration-specialiste-francais-circuits-integres/
