  Raytheon to design weather satellite prototype for US Space Force

  Nathan Strout WASHINGTON — The U.S. Space Force has selected Raytheon Intelligence & Space to build an advanced weather satellite prototype that can provide the military with theater weather imaging and cloud characterization, the company announced July 22. The Next Generation Electro-Optical Infrared Weather Satellite is intended to replace the Defense Meteorological Satellite Program, or DMSP, a series of satellites that have provided weather data for military operations since the 1960s. In 2015, Congress directed the Air Force to replace DMSP with a new weather system. As of last year, the satellites in the DMSP constellation were reaching the end of their service life, and the Pentagon expressed concerns that they may not last until a new satellite is launched in 2024. ORS-8, a planned replacement slated to launch in 2020 in partnership with NASA, was canceled by the space agency following protests. A free-flying spacecraft that could help provide weather data in the interim was scrapped by the Pentagon last year in favor of a distributed low-Earth orbit architecture. Raytheon says it can design the new satellite in eight months by leveraging weather system technology used on the Visible Infrared Imaging Radiometer Suite and Moderate Resolution Imaging Spectroradiometer. Raytheon did not disclose the prototype contract value. “Our system will gather all the info needed to not only build an accurate weather forecast, but to really understand what's going on in the atmosphere — both of which are essential to planning and executing a mission,” said Wallis Laughrey, vice president of space and command-and-control systems at Raytheon Intelligence & Space. “Understanding clouds and cloud movement could be used for things as simple as route planning for air-to-air refueling or to know where clouds might be covering an area of interest.” https://www.c4isrnet.com/battlefield-tech/space/2020/07/29/raytheon-designing-weather-satellite-prototype-for-the-space-force/

  Army selects companies to continue in long-range assault aircraft competition

  By: Jen Judson WASHINGTON — The Army has selected Bell and Sikorsky to enter into a competitive demonstration and risk reduction effort ahead of the start of the Future Long-Range Assault Aircraft, or FLRAA, program of record. The service is on a tight timeline to field a new long-range assault aircraft by 2030. The CDRR will consist of two phases that will last roughly one year each. The companies will deliver initial conceptual designs, an assessment of the feasibility of requirements and trade studies using model-based systems engineering. The competition for the program of record will begin in 2022 with a plan to field the first unit equipped in 2030. Congress added $76 million in funding to the aircraft program's top line in fiscal 2020 to drive down technical risk and speed up delivery. The money, which Congress approved as part of its FY20 appropriations bill signed into law in December, will fund the CDRR effort. The Army completed its Joint Multi-Role Technology Demonstration, or JMR TD, for which Bell and the Sikorsky-Boeing team each built aircraft to help the service understand what is possible for a future aircraft — mainly to replace the UH-60 Black Hawk. “These agreements are an important milestone for FLRAA,” Patrick Mason, the Army's aviation program executive officer, said in a statement issued March 16. “The CD&RR continues to transition technologies from the JMR-TD effort to the FLRAA weapons system design. We will be conducting analysis to refine the requirements, conceptual designs, and acquisition approach. Ultimately, this information and industry feedback are vital to understanding the performance, cost, affordability, schedule risks and trades needed to successfully execute the FLRAA program.” Bell has flown its V-280 Valor tilt-rotor demonstrator for two years in the JMR-TD and has logged more than 160 hours of flight time on the experimental aircraft. Sikorsky and Boeing's SB-1 Defiant coaxial demonstrator had a more difficult time getting off the ground due to issues in manufacturing its rotor blades. Its first flight was in March 2019. Even though Defiant has flown for a significantly reduced amount of time, the Army has determined it has enough data to move forward on its FLRAA program rather than extend the JMR TD to wait for the Sikorsky-Boeing team to log flight time. Brig. Gen. Wally Rugen, who is in charge of the service's future vertical lift modernization efforts, said last spring that because of the data collected through the JMR TD process as a well as additional studies and modeling, the service now thinks it has enough information to move more quickly into a full and open competition for FLRAA. Lt. Gen. Paul Ostrowski, the military deputy to the acquisition chief, said in a Senate Armed Services Airland Subcommittee hearing around the same time that the Army is presenting an acquisition strategy to the Pentagon's acquisition chief focusing on a nondevelopmental item approach to procuring FLRAA. That route, Ostrowski said, could lead to a competitive downselect by FY22. The extra funding provided by Congress will give the service the ability to continue to fly and burn down that inherent risk in developing a new helicopter. “What [that] may do as we hit those gates, is allow us to take what was going to be a primary budget, really a starting budget for the Army in ‘23 and ‘24, and potentially move that selection back to ‘23,” Rugen said recently. “We are not going to go to selection if, number one, we don't have requirements stable, we don't have resources stable, and, number two, the technology is not there.” The Army already has had a robust technology demonstrator program, including an extension, Rugen said, but that type of effort doesn't garner the same data as a prototype demonstration or a full-up weapon system. “In the CDRR [competitive demonstration and risk reduction], we're really trying to develop a weapons system, not the tech demonstrator,” Rugen said. “So we're trying to take it to the next level.” The CDRR will assess a laundry list of technologies identified through an Office of the Secretary of Defense-conducted independent technology readiness assessment, which would require additional evaluation to reduce risk, according to Rugen. Some of these technologies include the powertrain, drivetrain and control laws of the aircraft. “When we look at the software involved in flight controls, we have to really reduce risk there,” Rugen noted. The CDRR will also allow the Army to work on the integration of its mission systems. https://www.defensenews.com/land/2020/03/16/army-selects-companies-to-continue-on-in-long-range-assault-aircraft-competition/
