How DC became obsessed with a potential 2027 Chinese invasion of Taiwan

Some in defense circles say the U.S. needs to prepare for Beijing's invasion of Taiwan in 2027. China experts say it isn’t a deadline.

    Will this hybrid drone give Russia a high-altitude advantage?

    By: Kelsey D. Atherton Is it still a tiltrotor aircraft if the whole body tilts? The new “Fixar” drone, set to be presented at Russia's MAKS-2019 airshow in late August, is a hybrid of sorts, a quadcopter with fixed wings. With limited moving parts and a flexible design, it's the kind of dual-use technology worth watching and, perhaps, even imitating. “Many companies and UAV manufacturers will present their aircraft, concepts and models” at the MAKS-2019 airshow, said Samuel Bendett, an adviser at the Center for Naval Analyses. “This Fixar UAV is a ‘self-initiated' project by the manufacturer, with the hope of getting attention from potential civilian and military customers at the air show.” Unlike the more eponymous tiltrotor craft, which switch distinctly from rotor-powered takeoff and landing to propeller-driven level flight, the Fixar instead has its four rotors in a permanently fixed position. The engines remain in position while the whole frame of the aircraft can lean backwards for more traditional vertical flights or stay level to operate as a fixed-wing machine. While the Fixar's marketing photos show it working in fields of crops, manufacturer IKS also bills it as designed specifically to operate in windy conditions and in mountains, suggesting that the whole machine might have a role in ISR and cargo transport. “What caught my attention in particular was that the drone can operate in ‘mountainous conditions' due to its unique design,” said Bendett. “In fact, Russian military has been practicing the operation of different UAVs at high altitudes and in high wind — so this Fixar UAV can prove useful right away.” Like all duel-use platforms, a drone is only as useful as the payloads put on it. Cameras and supply storage are likely options, though nothing yet suggests any new demand on the airframe. An ability to fly fast and from small patches of land without a runway is valuable, but it needs to have a certain range and speed to be a better choice than the baseline low cost and simplicity of civilian quadcopters. A large internal security market might support that and could easily lead to the Fixar in police roles, as well. “At present, there is no UAV in the Russian military that has characteristics similar to the Fixar, but given a steady rate of UAS acquisition by the MOD — at 300 UAVs per year for the next several years — it's safe to assume that the Russian military is looking to diversify its UAV fleet beyond the workhorses like Eleton or Orlan," said Bendett. https://www.c4isrnet.com/unmanned/2019/08/13/will-this-hybrid-drone-give-russia-a-high-altitude-advantage/

    Les employés du DDPS sommés de refuser les invitations

    Les employés du DDPS ne peuvent plus accepter d'invitations d'entreprises actives dans le domaine de la défense, a décrété la conseillère fédérale Viola Amherd. Cette mesure vise à contrer des accusations de conflits d'intérêts dans le cadre du projet Air2030. Le projet Air2030 comprend l'acquisition de nouveaux avions de combat et d'un nouveau système de défense sol-air. En décembre, les médias avaient parlé d'officiers suisses participant à un buffet suédois dans un hôtel à Berne. Concrètement, la directive de la ministre de la défense Viola Amherd stipule que les employés de son département ne doivent pas participer à des manifestations organisées ou sponsorisées par des entreprises impliquées dans le projet Air2030, a déclaré jeudi le porte-parole du DDPS, Lorenz Frischknecht, confirmant une information des journaux CH-Media. Les contrevenants pourront être sanctionnés. Cela est également valable pour les invitations d'Etats impliqués dans l'acquisition d'avions de chasse, a dit M. Frischknecht. Il s'agit notamment de l'Allemagne, de la France, de la Suède, d'Israël et des Etats-Unis. Il peut s'agir de réceptions à l'occasion de fêtes nationales ou d'autres événements, tels que des conférences ou des expositions. Cinq avionneurs présentent leurs appareils dans le cadre du projet Air2030. L'Eurofighter (Airbus, Allemagne), le F/A-18 Super Hornet (Boeing, Etats-Unis), le Rafale (Dassault, France), le F-35A (Lockheed-Martin, Etats-Unis) et le Gripen E (Saab, Suède) seront testés au sol et dans les airs en Suisse de mi-avril à fin juin. https://www.rfj.ch/rfj/Actualite/Suisse/Les-employes-du-DDPS-sommes-de-refuser-les-invitations.html
