U.S. FCC proposes additional spectrum for drone communications

The U.S. Federal Communications Commission (FCC) on Wednesday proposed new rules to make licensed radio spectrum in the 5 GHz band for the rising number of unmanned aircraft systems, or drones, in use.

    Hypersonics by the dozens: US industry faces manufacturing challenge

    By: Jen Judson HUNTSVILLE, Ala. —The U.S. military is a few years from launching offensive hypersonic weapons that are currently under development. But building those initial missiles is one thing — manufacturing the weapons in multitude is another issue entirely. “I would say we really need to understand, again, how can we produce precision hardware at scale,” Michael Griffin, the Pentagon's undersecretary of defense for research and engineering, told a group of reporters Aug. 7 at the Space and Missile Defense Symposium in Huntsville, Alabama. “If we talk about ballistic missile defense or hypersonic offense and we talk about proliferating architectures, we need any dozens, many hundreds, maybe thousands of assets,” he added. “This takes us back to the Cold War where at one point we had 30,000 nuclear warheads and missiles to launch them. We haven't produced at that kind of scale since the wall came down.” As hypersonic missiles become a reality, industry is going to have to relearn how to effectively, efficiently and economically produce them, Griffin said. While industry has developed warheads, glide bodies and other components, there is no industrial base equipped to manufacture hypersonic weapons. Things are moving in the right direction when it comes to bringing industry up to speed and preparing for larger-scale manufacturing of missiles, Griffin said. But building these systems is challenging because, for example, hypersonics require a greater degree of thermal protection than what has been required of other weapons in the past, he noted. Building hypersonics is no longer a technical issue or a matter of understanding physics, but rather an issue of understanding the industrial engineering required to produce a larger number. “I'm not sure how much help the government can be there,” he said. “Mass production is not what we do. ... That is going to be an industry problem.” The Army is just weeks away from awarding a contract to a company that will work with the federally funded laboratory that developed a hypersonic glide body to develop manufacturing plans and strategies. Other companies will have a turn as well. The effort is spearheaded by the service's Rapid Capabilities and Critical Technologies Office. Griffin stressed that the weapons manufacturing process needs to be affordable. “Our adversaries have clearly found ways to make them affordable. China has these things now by the thousands. What do we do to learn, once again, how to produce sophisticated things at scale and affordably?” he said. China is able to field new systems every few years, Griffin noted, while the U.S. takes a decade or more to get through a cumbersome acquisition process. “It don't believe that the issues facing the United States aerospace and defense establishment are issues of specific technologies,” he said. “I believe that over the last 30 years ... we've become lost in our processes.” https://www.defensenews.com/digital-show-dailies/smd/2019/08/08/hypersonics-by-the-dozens-us-industry-faces-manufacturing-challenge/

    US Should Pull Drones From Missile Control Regime: Mitchell Institute

    "I have great hopes that this administration, with its bold unilateral actions on so many fronts, would take unilateral action with this regime on UAVs," says Keith Webster, former DoD head of defense cooperation. By THERESA HITCHENSon June 03, 2020 at 12:48 PM WASHINGTON: The Trump administration should unilaterally declare that it will no longer subject drone sales to export control restrictions under the Missile Technology Control Regime (MTCR), says a new Mitchell Institute study. And Congress should use the 2021 National Defense Authorization Act (NDAA) to redefine unmanned aerial vehicles (UAVs) as aircraft, which not only remove them from MTCR restrictions but also would ease US domestic export controls, asserts the paper, “”Modernizing UAV Export Policy for Effective Coalition Forces,”. “The US Congress should craft language in the 2021 NDAA that defines UAVs as aircraft, not cruise missiles, but as aircraft, and subject to the same export considerations as any other military aircraft,” said Heather Penny, senior resident fellow at Mitchell and the paper's author, during a webinar today. “We believe that this language, a statute, would be sufficient to be able to remove UAVs from being subject to the MTCR guidelines.” The 35-nation MTCR agreement requires a “strong presumption of denial” for sales of so-called Category 1 drones — those that can carry a 500 kilogram payload more than 300 kilometers. The Category 1 definition is considered as the minimum capability a missile needs to carry a nuclear warhead. Smaller unmanned aerial vehicles also are covered under MTCR's Category 2 rules, but those export restrictions are less stringent. Even the treaty-hating Trump administration sees the MTCR — a political agreement rather than a treaty — as a key tool in preventing the proliferation of ballistic and cruise missiles. This is despite its long-standing efforts to ease drone sales to allies, including through revamping US domestic law to allow “Direct Commercial Sales” by companies, rather than requiring all sales to go through the formal Foreign Military Sales process that requires approval by DoD, the State Department and Congress. Indeed, over the past year the administration tried — and failed — to convince its MTCR partners to revamp the rules to allow drones flying less than 800 kilometers per hour to slip out from under the Category 1 rules, said Penny. Washington is now expected to try again at the annual MTCR signatories meeting, she said, instead suggesting a 600 kph speed limit as the line of demarcation between the two categories of export restrictions. (The meetings are usually held in the fall, although there has yet to be an announcement of the 2020 dates.) But, Penny argued, even if this new effort comes to fruition, it would fail to fix the underlying problem of allowing allies to buy high-end US combat drones — and preventing them from fully integrating with US operations. Secondly, she asserted, complying with MTCR rules “distort the market” in favor of Chinese sales, she said, since China is not a member of the MTCR and has few formal restrictions on arms exports. “Continuing to adhere to and apply MTCR guidelines to UAVs facilitates Chinese strategic interests,” Penny said. “It's working against US interests.” Keith Webster, former DoD head of defense cooperation, agreed — calling efforts to revise the MTCR as a “Band-Aid” that would soon loose viability because of the rapid pace of technology improvement. “I wish we would act unilaterally,” he told the Mitchell Institute webinar. “We have the ability to act unilaterally. And I would like to see us do so very soon. I have great hopes that this administration, with its bold unilateral actions on so many fronts, would take unilateral action with this regime on UAVs.” That doesn't mean, Webster hastened to add, pulling out of MTCR itself. “Stay in the MTCR,” he said. “It served its purpose.” The experts acknowledged that a unilateral US move to exempt UAVs from MTCR could spur other nations to do the same for their own weapons systems that could exacerbate nuclear proliferation. Penny stressed that it was key for the US to renew its commitment to nonproliferation of ballistic and cruise missiles, and support MTCR's rules for those systems. Saying that “we need to be honest with ourselves about the implications” while seeking “creative solutions” to the UAV issue, Webster seemed to suggest that ultimately the US may decide the MTCR itself isn't worth the trade off. “There are challenges with compliance within the regime with at least one member,” he warned. As Breaking D readers know, US military leaders and Congress have sounded the alarm on the proliferation of cruise missiles by Russia (an MTCR member) and China that can more easily slip through US ballistic missile defense systems. This is especially true for hypersonic missiles, which have speeds above Mach 5 and while visible on radar are extremely hard to target. https://breakingdefense.com/2020/06/us-should-pull-drones-from-missile-control-regime-mitchell-institute/
