Le drone de combat furtif RQ-180 officiellement dévoilé

Dans une vidéo publiée récemment, l'US Air Force a dévoilé ce qui pourrait probablement être le drone de combat le plus important de sa génération : le RQ-180. Appartenant à la classe des drones HALE (haute altitude longue endurance), le RQ-180 afficherait une autonomie approchant les 36 heures, un double système de propulsion avec entrée d'air dorsale, et une cellule fortement similaire à celle du X-47B sans empennage arrière. Dans la vidéo, l'USAF révèle les premières images de ce qui pourrait être le RQ-180, surnommé « White Bat » (chauve-souris blanche). USAF a d'ailleurs recréé en 2019 le 74e escadron de reconnaissance sur la base aérienne de Beale (Californie) avec un insigne représentant une chauve-souris blanche. Le concept de furtivité a été très largement exploré aux Etats-Unis pour les bombardiers stratégiques tels le B-2A Spirit de Northrop ou le F-117 de Lockheed Martin, puis pour les chasseurs comme le F-22, les premiers drones mis en service autour des années 2000 devaient surtout permettre une bonne permanence sur zone.

    German ministry seeks data on quicker fighter jet deliveries

    Andrea Shalal BERLIN (Reuters) - The German military has asked potential bidders in a high-stakes competition to replace its aging Tornado fighter jets about accelerating deliveries of new warplanes before an initial target date of 2025, sources familiar with the matter said. The defense ministry posed the question in early August in a follow-up to its initial request for information from Europe's Airbus (AIR.PA) and Lockheed Martin (LMT.N) and Boeing (BA.N), both from the United States, the sources said. The ministry had no comment on the latest twist in a tender that could be worth billions of euros. One of the sources said the request signaled concerns about the growing cost of servicing the current fleet of 85 operational Tornado jets. Defence Minister Ursula von der Leyen says she favors a European solution - the Eurofighter Typhoon built by Airbus, Britain's BAE Systems and Italy's Leonardo SpA (LDOF.MI) - but Lockheed and Boeing still hope for a chance to bid for the work. Airbus and the U.S. government submitted data this spring about the four fighter jet models under consideration - the Eurofighter, Lockheed's F-35, and the Boeing F/A-18E/F or F-15E. Germany is studying a number of options, including buying one type of jet to replace the Tornado jets, a split buy of two aircraft types, and a service life extension of the Tornado jets, according to multiple sources familiar with the process. Germany has also asked Washington for information about the possibility of leasing Boeing F-15 fighter jets, two sources said, although that is seen as an unlikely outcome. Von der Leyen in July said she expected a preliminary decision on the next steps by the end of the year. POSSIBLE SPLIT BUY? One proposal calls for Germany to buy 40-45 Lockheed F-35 jets to replace those Tornados that can carry nuclear bombs, and about 75 new Eurofighters to replace both the other Tornados and a first batch of Eurofighters delivered between 2003 and 2008. Buying F-35s would allow Germany to keep a mixed fleet of fighter jets, a key requirement in its military strategy, while averting costly and time-consuming modifications to the process of certifying the Eurofighter to carry nuclear bombs. Although not a nuclear power, Germany hosts some U.S. nuclear warheads under NATO's nuclear-sharing policy and operates a number of Tornado warplanes that can deliver them. The U.S. has told Germany it could take 12 to 18 months to study the Eurofighter certification issue. German industry executives are pressing for quick answers, given that the already high cost of keeping the Tornado jets flying could rise once Britain and Italy phase out their fleets. “The cost of spare parts and operations keeps going up,” one industry executive said. https://www.reuters.com/article/us-germany-fighter/german-ministry-seeks-data-on-quicker-fighter-jet-deliveries-idUSKCN1LR24V
