  Deux candidats encore en lice pour l'achat de la défense sol-air

  Berne (awp/ats) - Deux systèmes de défense sol-air de longue portée sont encore dans la course pour le renouvellement de la défense de l'armée suisse. Le consortium français Eurosam et la société américaine Raytheon ont transmis leurs offres. Israël a renoncé. La soumission de cette première offre marque le début de la phase d'analyse et d'essais, a indiqué armasuisse lundi. Un deuxième appel d'offres aura lieu dans le courant de l'hiver prochain. Des spécialistes du Département fédéral de la défense vont analyser les offres des fabricants en évaluant l'efficacité des différents systèmes et en testant la performance du radar. Aucun essai de tir ne sera effectué. Ces analyses donneront lieu à des rapports individuels. Les candidats ne seront comparés qu'ensuite. Suivra un deuxième appel d'offres. Le Conseil fédéral tranchera. La surface à couvrir par la défense sol-air doit être de 15'000 km2 au moins. Le système doit atteindre une altitude d'engagement de plus de 12'000 m et une portée supérieure à 50 km. Il n'est pas nécessaire de disposer d'une capacité de défense contre des missiles balistiques. Le renouvellement des moyens de défense sol-air de longue portée fait partie du programme d'achat de la nouvelle flotte d'avions de combat de l'armée suisse. La facture totale se monte à 8 milliards de francs suisses. Cinq appareils sont évalués pour remplacer les Tiger et les F/A-18 de l'armée: le Gripen E suédois (Saab), le Rafale français (Dassault), l'européen Eurofighter (Airbus), ainsi que les américains Super Hornet de Boeing et le F-35A de Lockheed-Martin. https://www.zonebourse.com/SAAB-6491624/actualite/Deux-candidats-encore-en-lice-pour-l-achat-de-la-defense-sol-air-28231928/

  Northrop Grumman and Airbus Finalize Agreement on “Wing of Tomorrow” Program

  Agreement positions company for work on next generation composite manufacturing technology DULLES, Va. – Oct. 16, 2018 – Northrop Grumman Corporation (NYSE: NOC) announced today it has finalized a Cooperation and Research Agreement to work closely with Airbus on the Wing of Tomorrow program. The three-year agreement expands the current Northrop Grumman relationship with Airbus and explores complex composite wing stiffener forming automation with out-of-autoclave material systems through an investment in equipment, test articles and engineering support. This relationship positions Northrop Grumman for future potential high-rate production opportunities. “This agreement builds on Northrop Grumman's valuable working relationship with Airbus and its partners. Our work with Airbus is an important component of growth in the commercial aerospace structures business,” said Wendy Williams, vice president and general manager, aerospace structures, Northrop Grumman. “We are excited about the advanced composite manufacturing technology being developed to support the Wing of Tomorrow concept, and our team is eager to continue our long-term relationship with Airbus on their future endeavors.” Northrop Grumman is currently producing composite fuselage stringers and frames for the Airbus A350 XWB -900 and -1000 variants at its state-of-the-art Aircraft Commercial Center of Excellence facility in Clearfield, Utah. The company has successfully delivered more than 200,000 Airbus A350 parts since the inception of the program. Northrop Grumman's proprietary automated stiffener forming process has been instrumental in the development and manufacture of high-rate production composite stringers and frames that are extremely high quality, affordable and dimensionally precise. This technology will be evolved to the new material systems, geometries and processing needs of the future while maintaining the superior benefits of a highly automated production process. The Airbus Wing of Tomorrow program will address future aggressive aircraft production rates and the requirement for wings to be made faster and more affordably. The program will explore the best materials, manufacturing and assembly techniques, as well as new technologies in aerodynamics and wing architecture. New material experimentation represents a major part of the program, and lower-cost composite technologies currently being pursued could enable wing components to be produced with significantly reduced equipment and tooling costs, along with enabling a faster production cycle. Increased use of composite materials also opens up new possibilities in terms of wing configuration and construction. Northrop Grumman is a leading global security company providing innovative systems, products and solutions in autonomous systems, cyber, C4ISR, space, strike, and logistics and modernization to customers worldwide.
