  Lockheed Martin to Integrate New Situational Awareness System for F-35

  By Frank Wolfe Lockheed Martin is to integrate the Raytheon Next-Generation Electro-Optical Distributed Aperture System (DAS) into all F-35 variants over the next two years under a nearly $99 million contract announced by the Pentagon on Dec. 30. The system is to provide "360-degree situational and environmental awareness day or night," according to Raytheon, for navigation, missile and aircraft detection and tracking. The pilot's helmet is to receive high-resolution, real time imagery from six external infrared cameras. Northrop Grumman developed the current AN/AAQ-37 DAS, but bowed out of a bid for the follow-on program in 2018, as company executives said that the pay-off would be higher for other business opportunities. Lockheed Martin is to perform the integration work on the new Raytheon DAS in Ft. Worth and finish the work by July 2022 for delivery to the F-35 fleet beginning in 2023 with production Lot 15 aircraft. As Pentagon officials follow congressional direction to reduce F-35 sustainment costs and improve aircraft performance, Lockheed Martin has said that the Raytheon DAS will lead to more than $3 billion in life cycle cost savings, a 45 percent reduction in unit recurring costs, a more than 50 percent reduction in operations and sustainment costs, five times more reliability, and twice the performance capability. Raytheon has also been moving to install the Stormbreaker smart bomb, previously known as Small Diameter Bomb II, on the F-35. Stormbreaker has a tri-mode seeker that uses imaging infrared, millimeter wave, and a semi-active laser to destroy moving targets in adverse weather from up to 45 miles away. Raytheon said that it completed integration of the Stormbreaker on the U.S. Air Force F-15E Strike Eagle by Boeing in April, 2018. Integration of the Stormbreaker on U.S. Navy F/A-18 E/F aircraft by Boeing and the Lockheed Martin F-35 has begun. All F-35 variants are to carry Stormbreaker by 2023, according to Raytheon, which said that the F-35 can carry eight Stormbreaker weapons internally and eight on the wings. https://www.aviationtoday.com/2020/01/14/lockheed-martin-to-integrate-new-situational-awareness-system-for-f-35/

  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, Philippines expand exercise to territorial edges amid tension with China

  The U.S. is continuing to find ways to fortify defenses across the Pacific to deter China and counter its influence. The Philippines is key to that effort.
