  Le Japon va acquérir 105 avions de combat américains F-35

  Le Japon va acheter 105 avions de combat américains F-35 supplémentaires, a annoncé lundi le président américain Donald Trump à l'issue d'un sommet avec le premier ministre japonais Shinzo Abe. « Les États-Unis soutiennent les efforts du Japon pour améliorer ses capacités de défense, et ces derniers mois nous leur avons envoyé une grande quantité d'équipements militaires », a déclaré M. Trump lors d'une conférence de presse, annonçant « l'intention du Japon d'acheter 105 F-35 neufs ». Le Japon, qui avait déjà annoncé fin 2011 l'achat de 42 F-35, est avec cette nouvelle commande le premier client international pour cet avion de combat de cinquième génération. En réalité, l'archipel s'était déjà engagé en décembre à cette acquisition, portant à 147 le nombre de ces chasseurs furtifs en sa possession, selon un communiqué du constructeur aéronautique américain Lockheed Martin publié à l'époque. Le gouvernement de Shinzo Abe, qui a annoncé en décembre un budget record pour la défense, a accru ses importations d'équipements militaires américains sous la pression de Donald Trump. Le but est de contrer la menace militaire de la Chine, mais aussi de réduire le déséquilibre commercial avec les États-Unis, régulièrement dénoncé par le président américain. Lancé au début des années 1990, le F-35 est produit par Lockheed Martin, et ses moteurs par un autre américain, Pratt et Whitney. Selon les derniers chiffres, 390 F-35 ont été livrés dans le monde. C'est le plus cher des programmes d'armement de l'histoire militaire américaine, avec un coût estimé au total à près de 400 milliards de dollars pour l'armée américaine, pour un objectif de près de 2500 appareils à produire dans les décennies à venir. https://www.lapresse.ca/affaires/201905/27/01-5227679-le-japon-va-acquerir-105-avions-de-combat-americains-f-35.php

  Russia plans to arm its most advanced fighter with new hypersonic air-to-air missiles meant to cripple the F-35 stealth fighter

  Ryan Pickrell Russia's most advanced fighter jet, the Sukhoi Su-57, will reportedly carry the hypersonic R-37M long-range air-to-air missile, a new weapon with the ability to strike targets hundreds of miles away. The Chinese are developing similar systems for their fighter jets. These weapons, assuming US rivals can take them from testing to deployment, could pose a threat to rear support aircraft such as early warning and aerial refueling aircraft, key force multipliers for American jets like the F-35 Lightning II Joint Strike Fighter. Russia reportedly plans to arm its most advanced fighter jet with a powerful hypersonic air-to-air missile that can take aim at aircraft nearly two hundred miles away, making them a potential threat to critical US air assets. The Su-57 multipurpose fighter jet, a fifth-generation stealth fighter built for air superiority and complex attack operations that is still in development, will be armed with the new R-37M, an upgraded version of an older long-range air-to-air missile, Russia Today reported Thursday, citing defense officials. The Russian Ministry of Defense is reportedly close to completing testing for this weapon, the development of which began after the turn of the century. With a reported operational range of 186 to 248 miles and a top speed of Mach 6 (4,500 mph), the R-37M is designed to eliminate rear support aircraft, critical force multipliers such as early warning and aerial refueling aircraft. Russia asserts that the missile possesses an active-seeker homing system that allows it to target fighter jets during the terminal phase of flight. While Russia initially intended to see the weapon carried by the MiG-31 interceptors, these missiles are now expected to become the primary weapons of the fourth-generation Su-30s and Su-35s, as well as the next-generation Su-57s. The weapon's specifications were modified to meet these demands. The Russians are also apparently developing another very long-range air-to-air missile — the KS-172, a two-stage missile with a range said to be in excess of the R-37M's capabilities, although the latter is reportedly much closer to deployment. China, another US competitor, is also reportedly developing advanced long-range air-to-air missiles that could be carried by the reportedly fifth-generation J-20 stealth fighter. The China Dailyreported in January 2017 that photos of a J-11B from the Red Sword 2016 combat drills appeared to show a new beyond-visual-range air-to-air missile. "China has developed a new missile that can hit high-value targets such as early-warning planes and aerial refueling aircraft, which stay far from conflict zones," the state-run media outlet reported, citing Fu Qianshao, an equipment researcher with the People's Liberation Army Air Force. Slow, vulnerable rear-support aircraft improve the overall effectiveness of key front-line fighter units, such as America's F-35 Lightning II Joint Strike Fighter, which just conducted its first combat mission. The best strategy to deal with this kind of advanced system is to "send a super-maneuverable fighter jet with very-long-range missiles to destroy those high-value targets, which are 'eyes' of enemy jets," Fu told the China Daily, calling the suspected development of this type of weapon a "major breakthrough." The missiles being developed by US rivals reportedly have a greater range than the American AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM), giving them a potential edge over US military aircraft. The Russian Su-57 is expected to enter service in 2019, although the Russian military is currently investing more heavily in fourth-generation fighters like the MiG-29SMT Fulcrum and Su-35S Flanker E, which meet the country's air combat needs for the time being. Russia canceled plans for the mass production of the Su-57 in July after a string of development problems. There is some evidence the aircraft may have been active in Syria earlier this year, but the plane remains unready for combat at this time. Military analyst Michael Kofman previously told Business Insider that the Su-57 is "a poor man's stealth aircraft," adding that it doesn't quite stack up to the F-35 or F-22. https://www.businessinsider.com/russia-plans-to-arm-su-57-jets-with-new-hypersonic-air-to-air-missiles-2018-9
