  Air Force study on future aerial refueling tanker could start in 2022

  By: Valerie Insinna WASHINGTON — The Air Force could begin to lay out its vision for a future aerial refueling tanker, previously known as KC-Z, as early as next year, the head of Air Mobility Command said Monday. The service intends to conduct an analysis of alternatives for an advanced aerial refueling aircraft in fiscal year 2022, AMC commander Gen. Jacqueline Van Ovost said during a Defense Writers Group meeting with reporters. That study will help the Air Force determine precisely which capabilities a future tanker will need to to operate in more heavily contested battlefields against the threats posed by nations such as Russia and China. “We're thinking about the near peer [competition], and what we need for a near peer [competition],” she said. Key to that discussion is figuring out how much of the aerial refueling process can be performed without a human pilot or boom operator onboard the plane to fly it or give other aircraft gas. “Is going to be autonomous? Is it going to be pilot on the loop [or] pilot in the loop capability?” asked Van Ovost. “Is it going to be small? Is it going to be large? What kind of [self protection] is it going to have? What kind of electromagnetic spectrum capabilities is it going to have to both protect itself and enhance the lethality of the Joint Force while it's out there?” In April, Will Roper, then the Air Force's top acquisition official, told reporters that an agreement with Boeing for a new and improved KC-46 vision system could pave the way for autonomous aerial refueling. The addition of 4K high-definition cameras, modern processors and LiDAR (light detecting and ranging) sensors would help the new system accumulate much of the data necessary for a computer to correctly calculate all the variables that need to be solved for safe aerial refueling. “All you have to do is take that data that tells the world inside the jet the reality of geometries between the airplane and the boom outside the jet. Once you have that, you simply need to translate it into algorithms that allow the tanker to tank itself,” Roper said then. The Air Force is not the only service interested in automated aerial refueling. The Navy is flight testing the MQ-25 Stingray aerial refueling drone — which, like the Air Force's new KC-46 tanker, is built by Boeing. The Navy eventually hopes to operate the MQ-25 onboard aircraft carriers, where it will be used to extend the range of fighter jets like the F-35C and F/A-18EF Super Hornet. Van Ovost acknowledged the Air Force is still years away from being able to hold a competition for the platform formerly known as KC-Z. After the Air Force completes its procurement of 179 KC-46s — which, if its current buy rate holds, will occur around the 2027 timeframe — the service will buy a non-developmental “bridge tanker,” she said. That effort, which replaces the KC-Y program, will likely be a battle between Boeing and an Airbus-Lockheed Martin team, which joined forces in 2018 to market Airbus' A330 Multi-Role Tanker Transport to the U.S. Air Force. Both teams are expected to offer upgraded versions of their current aerial refueling aircraft. Van Ovost did not say when that competition will begin. Along with tackling questions about its future tanker, the Air Force is also set to begin a business case analysis whether to pursue contracted aerial refueling to support U.S. military training and test activities across the contiguous United States. After holding a Dec. 19 industry day with interested vendors, Air Mobility Command conducted a study into the feasibility and affordability of commercial air refueling services and submitted a proposal to Air Force leadership. However, Air Force leaders want more information before making a final decision, and have asked for a comprehensive business case analysis that would finalize a requirement for all of the services' needs, Van Ovost said. The study would come up with options for various contracting models — which could include tankers that are leased to the government or contractor-owned and operated — as well as hammer out details on Federal Aviation Administration certification requirements. “We're working with headquarters Air Force to finalize the parameters for the study, and then likely will be contracting out that study,” Van Ovost said. “And for expectation's sake, it does take a while. These kinds of business case analysis we have seen take 18 months, so we are going to put pen to paper and take a very close look at it.” https://www.defensenews.com/air/2021/02/02/air-force-study-on-future-aerial-refueling-tanker-could-start-in-2022/

  FCC and Ligado are undermining GPS – and with it, our economy and national security

  Sen. Jim Inhofe, Sen. Jack Reed, Rep. Adam Smith, Rep. Mac Thornberry Right now, the coronavirus is rightly our country's most immediate concern. But the Federal Communications Commission has used the crisis, under the cover of darkness, to approve a long-stalled application by Ligado Networks — a proposal that threatens to undermine our global positioning system (GPS) capabilities, and with it, our national security. The FCC granted Ligado (formerly known as LightSquared) permission to repurpose spectrum adjacent to GPS frequencies for a terrestrial cellular network — framing this proposal as essential to “winning the race to 5G.” But what Ligado has done is conflate two different and important spectrum issues: the sharing of mid-band 5G spectrum by the Department of Defense and commercial industry, and harmful interference of Ligado's signal with the low-band GPS signals used in nearly every aspect of daily life. The result: some members of Congress, members of the administration, and the public are now confused about the real and immediate impacts of Ligado's proposal. So, we wanted to clarify things: domestic 5G development is critical to our economic competiveness against China and for our national security. The Pentagon is committed working with government and industry to share mid-band spectrum where and when it makes sense to ensure rapid roll-out of 5G. [Editor's note: C4ISRNET first broke the news that the FCC would move forward with Ligado's request on April 10.] The problem here is that Ligado's planned usage is not in the prime mid-band spectrum being considered for 5G — and it will have a significant risk of interference with GPS reception, according to the National Telecommunications and Information Administration (NTIA). The signals interference Ligado's plan would create could cost taxpayers and consumers billions of dollars and require the replacement of current GPS equipment just as we are trying to get our economy back on its feet quickly — and the FCC has just allowed this to happen. Think of all the ways Americans use GPS each and every day. GPS satellites provide free precise timing and navigation that powers thousands of functions: making financial transactions at our banks, keeping the lights on in our homes, traveling around the country — the list goes on and on. Studies show GPS satellites contribute at least $1 billion to our economy every single day. GPS also forms the backbone of countless military operations and applications — to get supplies to our war fighters on the battlefield, guide unmanned aircraft and vehicles, target its precision weapons, and much more. It would be practically impossible to identify and repair or replace all of the potentially adversely affected receivers. It would “needlessly imperil [Department of Defense] GPS-dependent national security capabilities,” per Secretary Esper, putting the war fighter, U.S. Space Force, military readiness, and even the defense of our homeland at risk. American families and businesses would lose coverage or be forced to use systems from our strategic competitors, China and Russia, jeopardizing our global leadership in precision timing. We're not the only ones with serious concerns. Nine federal departments and agencies have completed extensive engineering tests and analyses on Ligado's proposal; and the results are clear: Ligado's plan would interfere with millions of GPS receivers across the nation. The Departments of Defense, Commerce, Interior, Justice, Homeland Security, Energy, and Transportation — as well as NASA, the National Science Foundation, the Coast Guard and the Federal Aviation Administration — all strongly object to Ligado's plan. What kind of precedent is the FCC setting by disregarding near unanimous opposition of federal agencies to this proposal? It's not just the government, either — industry leaders representing GPS, satellite communications services, automotive companies, commercial aviation, and weather data have also voiced concerns over Ligado's proposal. We would expect that the FCC listen not just to Ligado's privately funded research, but also broad-based, in-depth research from experts in national security and other fields. This makes it all the more confusing — why is the FCC ignoring all the evidence, especially now, at the height of a global crisis? The Ligado application highlights the need to use a technical, data-driven approach to balance the use of the spectrum between war fighter requirements and commercial needs, rather than strong-arming a proposal through the process like the FCC just did. We can expect this issue to be an ongoing national security challenge. If we want to strike a responsible balance moving forward, the U.S. government must modernize the infrastructure needed to manage and share spectrum efficiently, promote policy and technology innovation, and improve the ability of military systems to operate alongside commercial systems. Considering the risks, it's clear the FCC commissioners made the wrong decision regarding Ligado's plan, which will set a disastrous precedent while impeding ongoing work on spectrum sharing. The vulnerabilities to our national and economic security are not worth the risk, particularly for a band of spectrum that isn't necessary to secure a robust 5G network. We encourage the FCC to withdraw its approval of Ligado's application and take this opportunity to work with the NTIA and other federal agencies, including the Departments of Defense and Transportation, to find a solution that will both support commercial broadband expansion and protect national security assets. Moreover, we expect the FCC to resolve Department of Defense concerns before moving forward, as required by law. If they do not, and unless President Trump intervenes to stop this from moving forward, it will be up to Congress to clean up this mess. Senator Jim Inhofe, R-Okla., is the chairman of the Senate Armed Services Committee. Sen. Jack Reed, D-R.I., is the ranking member on the Senate Armed Services Committee. Rep. Adam Smith, D-Wash., is the chairman of the House Armed Services Committee. Rep. Mac Thornberry, R-Texas, is the ranking member of the House Armed Services Committee. https://www.c4isrnet.com/breaking-news/2020/04/22/fcc-and-ligado-are-undermining-gps-and-with-it-our-economy-and-national-security/
