    Nouvelle version du Black Eagle 50

    Steadicopter présente une nouvelle version de son drone Black Eagle 50. A l'occasion du salon DSEI, l'entreprise israélienne Steadicopter présentera une version modernisée du Black Eagle 50. Cet aéronef correspond à un drone VTOL (à décollage et atterrissage vertical), capable de mener des missions civiles et militaires. Il a principalement été mis au point pour la conduite d'opérations ISTAR (renseignement, surveillance, acquisition de cible, reconnaissance). La nouvelle version du Black Eagle 50 repose sur deux nouveautés majeures. D'une part, l'aéronef a été équipé d'un système de navigation inertielle, lui permettant de se déplacer sans accès au signal GPS et de calculer les coordonnées de l'appareil en permanence. Deuxième grosse amélioration apportée au Black Eagle 50, l'appareil a été modifié afin de pouvoir conduire des missions en environnement naval, voire même d'être embarqué à bord d'un b'timent. Le Black Eagle 50 peut ainsi désormais conduire des missions sur terre et en mer. Son endurance, comprise entre 3 et 4 heures, et sa portée, pouvant atteindre les 150 km, lui permettent ainsi de couvrir de large périmètre à chaque mission. Equipé de capteurs permettant de conduire des missions en environnement diurne et nocturne, le Black Eagle 50 peut emporter une charge utile allant jusqu'à 5 kilos, pour une masse à vide de 27 kilos. Sa masse maximale au décollage est de 35 kilos. Par Justine BOQUET http://www.apps-drones.com/nouvelle-version-du-black-eagle-50-126255

    Japan Calls For STOVL Fighters, Plan For 42 F-35Bs Reported

    Bradley Perrett | Aerospace Daily & Defense Report BEIJING—A national security meeting of Japan's ruling party has called for the acquisition of shipboard fighters capable of short takeoff and vertical landing (STOVL), as a newspaper reports that substantial orders are planned for the version of the Lockheed Martin F-35Lightning that has that ability. Japan needs STOVL aircraft operated from currently available ships to guard against threats from its Pacific Ocean side of the country, according to a summary of results of the meeting published by the office of Prime Minister Shinzo Abe, days before the expected release of a five-year defense acquisition program. Buying 100 F-35s, including some of the F-35B STOVL version, has been expected in the five-year plan, which will start on April 1, 2019; they would be in addition to a current program for 42 F-35As. In fact, there will be 42 F-35Bs, the Mainichi newspaper said. They will operate from the helicopter carrier Izumo, which will reportedly be modified for that purpose. Modification of Izumo's sibling, Kaga, is not mentioned but would surely also occur, to ensure that one ship with F-35Bs was always available.
