    L'achat de 24 Eurofighter par le Qatar devient effectif

    Le contrat signé par le Qatar pour l'achat de 24 avions de chasse Typhoon Eurofighter est devenu effectif mardi, a annoncé l'industriel BAE qui a reçu la première tranche de paiement d'un contrat de 5 milliards de livres. "Ce contrat d'environ 5 milliards de livres (5,6 milliards d'euros, ndlr) est devenu effectif lorsque nous avons reçu le premier paiement ce jour", a expliqué dans un communiqué le groupe de défense britannique, membre du consortium européen Eurofighter aux côtés d'Airbus et de l'italien Finmeccanica. L'accord prévoit non seulement la livraison de 24 Eurofighter mais aussi de 9 avions d'entraînement avancés Hawk, ainsi que les services associés. Les appareils doivent commencer à être livrés à partir de 2022, a précisé l'avionneur. Un accord de principe en ce sens avait été conclu en septembre 2017 puis confirmé lors de la signature du contrat au mois de décembre suivant. Depuis le début de la crise avec ses adversaires arabes qui tentent de l'isoler depuis plus d'un an, le Qatar a pris de nombreuses mesures sur le plan international ou en interne, qui comprennent la signature de nombreux contrats d'équipement militaire. En juin 2017, Doha a signé un accord avec les Etats-Unis portant sur 12 milliards de dollars (10 milliards d'euros) pour l'achat d'avions de combat F-15. Deux mois plus tard, il a confirmé une commande de navires de guerre à l'Italie pour un montant de cinq milliards d'euros. En décembre, outre le contrat avec les Britanniques, le Qatar a signé des contrats de plus de dix milliards d'euros pour l'achat notamment d'au moins 12 avions de combat Rafale et 50 Airbus A321. Le consortium Eurofighter a conclu en mars dernier un protocole d'accord distinct avec l'Arabie Saoudite pour la livraison de 48 avions de chasse. Ryad a déjà reçu 72 appareils de ce type commandés il y a dix ans. Cet accord et celui avec le Qatar ont constitué une bouffée d'air frais pour le programme Eurofighter, qui avait dû ralentir dernièrement son rythme de production faute de commandes - poussant BAE Systems à annoncer en octobre 2017 la suppression de 1.400 emplois dans sa branche aéronautique. Le programme Eurofighter emploie plus de 100.000 personnes sur l'ensemble de la chaîne de fabrication, essentiellement en Europe, dont 40.000 au Royaume-Uni, où BAE Systems fait travaillere pour le moment 5.000 personnes directement pour fabriquer cet avion. https://www.journal-aviation.com/actualites/41110-l-achat-de-24-eurofighter-par-le-qatar-devient-effectif

    DARPA: Five Teams of Researchers Will Help DARPA Detect Undersea Activity by Analyzing Behaviors of Marine Organisms

    Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA's Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. This new, bio-centric PALS technology will augment the Department of Defense's existing, hardware-based maritime monitoring systems and greatly extend the range, sensitivity, and lifetime of the military's undersea surveillance capabilities. DARPA first announced the PALS program in February 2018 with the goal of incorporating biology into new solutions for monitoring adversary movements across the seemingly endless spaces of the world's oceans and seas. Ubiquitous, self-replicating, self-sustaining sea life is adaptable and highly responsive to its environment, whereas maritime hardware is resource intensive, costly to deploy, and relatively limited in its sensing modalities. According to PALS program manager Lori Adornato, “Tapping into the exquisite sensing capabilities of marine organisms could yield a discreet, persistent, and highly scalable solution to maintaining awareness in the challenging underwater environment.” The DARPA-funded PALS teams must develop or apply technologies to record stimulus responses from observed organisms, and develop combined hardware and software systems that interpret those responses, screen out false positives, and transmit analyzed results to remote end users. The teams' solutions will incorporate technologies such as hydrophones, sonar, cameras, and magnetic, acoustic, and kinetic sensors. The team led by Northrop Grumman Corporation, under principal investigator Robert Siegel, will record and analyze acoustics from snapping shrimp and optical activity by bioluminescent organisms. The team led by the Naval Research Laboratory, under principal investigator Lenny Tender, will integrate microbial organisms into a sensing platform to detect and characterize biological signals from natural microorganisms that respond to the magnetic signatures of underwater vehicles. The team led by Florida Atlantic University, under principal investigator Laurent Cherubin, will record and analyze vocalization cues from goliath grouper in tropical and subtropical environments. The team led by Raytheon BBN Technologies, under principal investigator Alison Laferriere, will use snapping shrimp as sources of opportunity for long-range detection, classification, and tracking of underwater vehicles. The team led by the University of Maryland Center for Environmental Science, under principal investigator David Secor, will tag black sea bass with sensors to track the depth and acceleration behaviors of schools of fish that are perturbed by underwater vehicles. DARPA is also funding the Naval Undersea Warfare Center, Division Newport, under principal investigator Lauren Freeman, to develop a seafloor system that uses a hydrophone array and acoustic vector sensor to continuously monitor ambient biological sound in a reef environment for anomalies. The system will analyze changes in the acoustic signals radiated by the natural predator-avoidance response of coral reef ecosystem biota, which could offer an indirect mechanism to detect and classify underwater vehicles in near-real time. DARPA conceived of PALS as a four-year research program with the expectation that researchers will be able to publish results for review by the broader scientific community. However, if DARPA identifies any of the data, results, or technical specifications as controlled unclassified information, DARPA will require the PALS researchers to protect them to prevent proliferation outside of official channels. https://www.darpa.mil/news-events/2019-02-15
