    Boeing to get $882M in withheld KC-46 funds back for COVID-19

    By: Valerie Insinna WASHINGTON — The U.S. Air Force will release $882 million to Boeing that it had retained due to ongoing technical problems involving the KC-46 tanker, the service announced Thursday. The move is meant to help the company make ends meet during the novel coronavirus pandemic. “This agreement provides Boeing $882M of withheld payments for previous non-compliance in 33 KC-46 deliveries,” the service said in a statement. “This withhold release is in line with Department of the Air Force and Department of Defense policies to maximize cash flow, where prudent, to combat coronavirus impacts on the industry base." When the U.S. Air Force agreed to take delivery of the first KC-46 tanker in January 2019, it made clear to Boeing that it still maintained a significant piece of financial leverage. The service could withhold a maximum of $28 million every time a new KC-46 was delivered — about 20 percent of the total sum due to Boeing. Air Force officials said they would hold back those funds until they saw measurable progress in fixing technical deficiencies, particularly the tanker's troubled Remote Vision System. By January, when Boeing had delivered 30 planes, the service had withheld about $800 million, according to Defense One. The Air Force and Boeing on Thursday announced a final agreement to fix the RVS, the imaging system used by boom operators to see the position of the receiver aircraft and the movements of the boom itself. According to the deal, Boeing will pay for both incremental fixes to current RVS software and hardware, as well as a complete redesign of the system with new cameras, processors and computers. Speaking with reporters about the decision on Thursday, Air Force acquisition executive Will Roper stressed that the service will be able to re-enact the cost penalties if Boeing's performance begins to slip. However, the service wanted to ensure that Boeing has the funding it needs to begin the RVS redesign, which it is calling RVS 2.0. “Have we given up our leverage? No, I think we've used it well," he said. “Part of what we committed to Boeing is to do an expedited review over the next 120 days for the 159 outstanding noncompliances. Boeing asserts that they have addressed those noncompliances, and we are going to review those quickly. We will not instate withholds over the 120 period, but if we put that some of the corrections that have been put in place don't make our requirement, then we will start withholds again.” As the largest maker of commercial planes in the United States, Boeing has been hit particularly hard by the COVID-19 pandemic, which has spurred travel restrictions and called into question commercial airlines' ability to pay for Boeing aircraft already on order. Meanwhile, Boeing announced last week that it would shutter operations for two weeks at its facilities in the Seattle, Washington, area due to the high number of COVID-19 cases in the state. Those production operations include the manufacturing of the KC-46 at Everett and the P-8 submarine-hunting plane in Renton. The Air Force intends to buy 179 tankers over the KC-46 program of record. https://www.defensenews.com/air/2020/04/02/boeing-to-get-882m-in-withheld-kc-46-funds-back-for-covid-19

    The Army wants drones that make their own networks

    By: Kelsey D. Atherton Eventually, the Shadow will come to pass. The Army is looking for replacements to the venerable drone, first flown in 1991, through its Future Tactical UAS program. In the nearly three decades since, every aspect of drone technology has seen some improvement, including materials used, sensors to communication hardware and software, and even the batteries that power those computers and sensors. The Army has also seen the limitations of what it can and cannot do with a drone that has to either operate from a runway or be launched from a rail and caught on a hook. Into this mix of requirements and new possibility flies the Resolute Eagle, made by PAE ISR, complete with an ad hoc network system from Persistent Systems. The Army is looking at a range of drones for possible Shadow replacement, and the Resolute Eagle will have to compete with designs as varied as Insitu's ScanEagle and Integrator, Martin UAV's V-Bat, Endeavor Robotics' Firstlook and SUGV, QinetiQ's Talon and Dragon Runner. This is a somewhat crowded field, and to compete in it Resolute Eagle has a VTOL model, which essentially grafts booms with rotors to the drone's wings, allowing it to take off and land like a quadcopter. The VTOL configuration is listed as having 12 hours of endurance, compared to 18 hours for the purely fixed-wing version, and the booms are detachable, giving some flexibility when forward deployed. “Our reconfigurable platform (from fixed wing to VTOL), large payload capacity, and reduced ground support equipment requirements offers significant mission flexibility, both as a Shadow replacement for BCT expeditionary forces and as a complement to the existing platforms currently in use for military and civilian uses,” said Beth Beach, vice president of business development at PAE ISR. Besides military customers, PAE ISR is targeting the Resolute Eagle at a broad range of law enforcement, the Department of Homeland Security, humanitarian and commercial missions, according to Beach. Its ISR abilities could be used for pipeline and railway inspection, as well as evaluating the area after a natural disaster and looking for people in search and rescue. Key to this is an ability to operate beyond line of sight through satellite communications. Relying on satellites is a safe bet for civilian applications going forward, but across the Pentagon people are looking for other ways to retain or set up communications networks on the battlefield in the event that the satellite communication becomes untenable. One way to ensure communication via drones is equipping the drones with tools for an ad hoc network. For the Resolute Eagle, that comes in the form of Persistent Systems' MPU5 Wave Relay mobile ad hoc networking (MANET). “The beauty of the MANET is that it can be setup and deployed with ease,” said Robert Regan, sales engineer at Persistent Systems. “Users can leave and enter the network seamlessly due to its self-healing and self-forming nature. When dealing with RF it is important to remember that every use case is different. So when dealing with distances there are lots of variables that can affect distance: RF environment, terrain, frequency band selected and antenna selection, just to name a few. With our auto-tracking antenna system we have reached out to UAV's at 130 miles.” This MANET is platform agnostic, and could operate not just from Resolute Eagle drones, but from multiple drones, ground robots, and in systems carried by people on foot. To keep the communication secure, MPU5 radio operates with AES 256-bit Suite B encryption, ensuring that only those with the right decryption tools (or the proper key) can access it. As the Army looks for its Shadow replacement, the capabilities on offer are what's most compelling, since they suggest the full range of possibility for a new mid-sized tactical drone. Crossing over from offering to contract is a not insignificant task, and in November 2018 US Naval Air System Command awarded PAE ISR a $173 billion contract for ISR services by Resolute Eagle. https://www.c4isrnet.com/unmanned/2019/01/16/resolute-eagle-brings-ad-hoc-networks-to-the-shadow-fight
