  Airbus reveals classified LOUT stealth testbed

  Airbus Defence & Space has revealed a more than decade-long research and demonstration effort into very low observable (LO) technologies, conducted as a classified effort for the German defence ministry. Showing its LO UAV testbed – or LOUT – platform at Manching on 4 November, Airbus future combat air system (FCAS) programme manager Mario Hertzog said the company began initial concept work in 2007. This led to a contract award in 2010 to refine configuration and material choices, and the production of a diamond planform demonstrator was completed in 2014. Pointing to the company's long involvement with LO reseach, Hertzog says: “Bringing all our experience into one programme was a logical conclusion.” The chosen configuration used for aerodynamic and anechoic chamber testing since 2014 has a roughly 12m (39.3ft) wingspan and similar length, and is described as a 4t-class vehicle. The subsonic design would use a conventional engine concealed behind a diverterless inlet, and has twin intakes blended into its upper fuselage. A cockpit transparency and sensor apertures also formed part of the testing. The aircraft's exhaust nozzle also is shielded from beneath, with Hertzog noting that such a vehicle would be optimised for use against ground-based air-defence systems. This mission requirement also led the company to hone LO techniques for the vehicle's landing gear doors and centerline internal weapons bay, Hertzog notes. Focus areas have included testing LO materials, including a radar absorbent structure for engine intake ducts, and on assessing radar frequency and infrared signature performance. Modelling work has also been conducted to analyse the likely acoustic characteristics of such a design. Airbus confirms that it has completed contracted work on LOUT, but says additional activities could be conducted. However, Hertzog declines to say whether Berlin could seek a flight-test campaign with such a system. Lessons learned from the LOUT programme will be available for potential adaptation during a long-term evolution activity on the Eurofighter Typhoon, and on a proposed French-German-Spanish FCAS development, Hertzog says. "Stealth is and will remain an enabler for survivability," he notes. https://www.flightglobal.com/news/articles/pictures-airbus-reveals-classified-lout-stealth-tes-462003/

  US Space Force to begin sharing technical space data with UK

  Nathan Strout WASHINGTON - The U.S. Space Force will begin sharing valuable space situational awareness data with the United Kingdom as part of Operation Olympic Defender, the service announced Aug. 14. Under a recently signed agreement, the Space Force will share it's Standardized Astrodynamics Algorithm Library with the U.K.‘s Ministry of Defense. SAAL is a collection of the Space Force's understanding of orbital physics and algorithms that helps the service predict the trajectories of objects on orbit. “Aggressive actions in space must be deterred through a multinational, coordinated effort, allowing for the defense and protection or our collective capabilities,” said Maj. Gen. DeAnna Burt, USSF director of Operations and Communications, in a statement. “Sharing the SAAL with our coalition partners enables greater cooperation and coordination between the U.S. and our Allies.” The agreement comes as part of Operation Olympic Defender, an American-led coalition of space-faring allies working together to deter hostile actions in space, strengthen deterrence against hostile actors and address the growing issue of orbital debris. Operation Olympic Defender was officially taken over by U.S. Space Command in May and is located at the Combined Space Operations Center at Vandenberg Air Force Base, California. The U.K. was the first nation to join Operation Olympic Defender and is the first to receive access to the SAAL. Under the new arrangement, that nation's Space operations Center will now be better able to collaborate with the Space Force, sharing algorithms and data to better predict orbital trajectories. The Space Force is looking to share the SAAL with more partners within Operation Olympic Defender. According to the announcement, the Secretary of the Air Force's International Affairs Office, SPACECOM and the Space Force have recognized a new framework that will allow other coalition partners to begin receiving SAAL. SPACECOM has signed a number of space data sharing agreements with other countries in recent months. https://www.c4isrnet.com/battlefield-tech/space/2020/08/18/space-force-to-begin-sharing-technical-space-data-with-uk/
