    US government may gain new power to track drones and shoot them down

    By: David Koenig, The Associated Press An aviation bill Congress is rushing to approve contains a little-noticed section that would give authorities the power to track, intercept and destroy drones they consider a security threat, without needing a judge's approval. Supporters say law enforcement needs this power to protect Americans from terrorists who are learning how to use drones as deadly weapons. They point to the Islamic State terrorist group's use of bomb-carrying drones on battlefields in Iraq, and warn that terrorists could go after civilian targets in the United States. Critics say the provision would give the government unchecked power to decide when drones are a threat. They say the government could use its newfound power to restrict drone-camera news coverage of protests or controversial government facilities, such as the new detention centers for young migrants. The provision is tucked in a huge bill that provides $1.7 billion in disaster relief and authorizes programs of the Federal Aviation Administration, which regulates drones. The House approved the measure Wednesday by a 398-23 vote, and the Senate is expected pass it on to President Donald Trump's desk in the coming days. The White House signaled support of the drone provision in July. Sen. Ron Johnson, a Wisconsin Republican, introduced the Preventing Emerging Threats Act this year. It would give the Homeland Security Department and the Justice Department power to develop and deploy a system to spot, track and shoot down drones, as unmanned aircraft are called. Officers would have the authority to hack a drone operator's signal and take control of the device. The bill was never considered on its own by the full Senate or the House. Instead, in private negotiations that ended last weekend, it was tucked into a "must-pass" piece of FAA legislation. Homeland Security Secretary Kirstjen Nielsen wrote in a recent op-ed that the threat of drone attacks "is outpacing our ability to respond." She said criminals use drones to smuggle drugs across the border, but worse, terrorists like the Islamic State are deploying them on the battlefield. "We need to acknowledge that our first and last chance to stop a malicious drone might be during its final approach to a target," she wrote. Attorney General Jeff Sessions said in a statement this week that the measure "would finally give federal law enforcement the authority we need to counter the use of drones by drug traffickers, terrorists and criminals." The National Football League's top security executive recently endorsed the bill's intent but said it should go further by letting trained local police officers intercept drones. The official, Cathy Lanier, a former Washington, D.C., police chief, said the NFL is alarmed by an increase in drone flyovers at stadiums. Opponents including the American Civil Liberties Union argue that the proposal gives the government unchecked power to track and seize drones without regard for the privacy and free-speech rights of legitimate drone operators. It exempts the government agencies from certain laws, including limits on wiretapping. The bill provides no oversight or means to question a government decision about what is a "credible threat" and what is an "asset" or "facility" in need of protection when drones are nearby. News organizations are increasingly using drones. They deploy them to cover natural disasters like the recent flooding from Hurricane Florence and also controversies such as the Trump administration's construction of new camps for migrant children who were separated from their parents at the U.S.-Mexico border. "Being able to see footage of protests, the size of protests, being able to see facilities like those at the border is useful — those are newsworthy events," said India McKinney, a legislative analyst for the Electronic Frontier Foundation. Without a specific means to protect First Amendment rights — something not in the bill — "it's entirely feasible to think that the DOJ or DHS could just decide that a drone owned by a news organization provides a credible threat and then destroys the footage," she said. ___ David Koenig can be reached at http://twitter.com/airlinewriter https://www.militarytimes.com/news/your-military/2018/09/28/government-may-gain-new-power-to-track-drones-and-shoot-them-down

  • KC-46 refueling system flaws will take years to fix and cost hundreds of millions, GAO says

    KC-46 refueling system flaws will take years to fix and cost hundreds of millions, GAO says

    By: Stephen Losey New designs will be required to fix some of the issues with the refueling boom and the remote vision system on the Air Force's new KC-46 Pegasus tanker, and that could take years to fix, the Government Accountability Office said in a report released Wednesday. The refueling boom on the Pegasus could inadvertently scratch fighter jets' stealth coatings, or otherwise damage aircraft, according to the GAO. The good news is that the cost of delivering all 179 KC-46 tankers is now expected to come in at $43 billion, or nearly $9 billion cheaper than originally estimated in 2011, GAO said in the report. More, the KC-46 is ultimately expected to meet all 21 of its performance goals. But delays in the program mean that Boeing will not be able to make good on its most significant delivery requirement — delivering nine sets of wing aerial refueling pods — until mid-2020, or nearly three years later than originally expected. In addition to previously reported foreign object debris problems, the GAO report details deficiencies with the tanker's remote vision system and refueling boom — which could damage aircraft, especially stealth coatings. As has been previously reported, the remote vision system's cameras sometimes had problems with glare when the sun shone at certain angles, GAO said. This caused the display screens to be washed out or blacked out during some test flights, and the aerial refueling operators had a hard time seeing the receiving aircraft's receptacles to guide in the boom. The system also doesn't provide enough depth perception in some lighting conditions, GAO said. Boeing said it has already made changes, such as adjusting the contrast on the display screen and allowing operators to more quickly switch between different viewing options. However, GAO responded that those changes didn't fix the underlying problem: KC-46 operators need to be able to refuel aircraft in all conditions, with sufficient visual clarity in all lighting conditions. Boeing has agreed to redesign the vision system to do so, but the redesign could take three or four years, plus several more years to install it in the planes. That vision problem also caused the boom nozzle to bump into the receiving aircraft, without the knowledge of the refueling operators. This could damage the antenna or other structures near the refueling receptacle, GAO said. This especially presents a problem for low-observable planes such as the F-22 fighter, because inadvertent boom nozzle contact could scratch or damage special stealth coatings, and make them visible to radar. GAO also said the Pegasus' telescoping boom is stiffer than expected, which means lighter aircraft — such as the A-10 and F-16 — must use more power to move the boom forward while in contact to compress it and stay in refueling position. The need for additional force can create a problem when the receiving planes disconnect from the boom. When they disconnect, their additional power can cause them to lunge forward back into the boom, which could damage the plane and the boom itself. For the A-10, because the receptacle is located on its nose, a collision with the boom could damage the windshield and put the pilot at a greater risk. Boeing said that fixing that problem will require a hardware change, which could take three or four years to be designed and certified by the Federal Aviation Administration. But because the contract didn't specify how much force should be needed to compress the boom, and because the Air Force signed off on Boeing's original proposed specifications, program officials said the Air Force will have to foot the bill. The total cost for designing and retrofitting roughly 106 KC-46s? More than $300 million, GAO said. https://www.airforcetimes.com/news/your-air-force/2019/06/13/kc-46-refueling-system-flaws-will-take-years-to-fix-and-cost-hundreds-of-millions-of-dollars-gao-says/
