  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/

  Lockheed dives into next-generation missile defense interceptor competition

  By: Jen Judson WASHINGTON — Lockheed Martin said it will compete to build the Missile Defense Agency's Next-Generation Interceptor designed to protect the homeland against intercontinental ballistic missile threats from North Korea and Iran. The company is “excited to confirm that we are putting in a bid for the Next-Generation Interceptor,” Sarah Reeves, Lockheed's vice president of missile defense programs, told reporters Aug. 3. Bids were due July 31. Boeing and a Raytheon-Northrop Grumman team have already announced their intentions to compete to develop and field the agency's new interceptor following the cancellation of the Redesigned Kill Vehicle meant to replace the warhead on the current Ground-Based Interceptors. Those missiles are part of the Ground-based Midcourse Defense System, which is operational at Fort Greely, Alaska, and Vandenberg Air Force Base, California. The RKV program was paused in May 2019 and then abruptly terminated in August 2019 due to insurmountable technical issues resulting in delayed schedules and cost increases. The Defense Department announced at the time that it would embark on an entirely new program to field a future interceptor. MDA now plans to downselect to two companies, which will then compete for the right to build the interceptor. While MDA struggled with RKV, Lockheed invested the last two decades on multi-kill vehicle technology,” Reeves said. Lockheed had one of three small contracts to design a kill vehicle that could take out multiple warheads several years ago that would lead to a program that would replace the RKV called the Multi-Object Kill Vehicle (MOKV) program. Raytheon and Boeing had won the remaining two contracts. Reeves stressed the need for the new interceptor to be able to go after threats that disperse multiple objects including decoys. “We are looking carefully at the lessons learned from RKV including parts survivability testing which, in that program, was done too late and caused a major system redesign, as well as ensuring early-and-often testing and fly-before-you-buy mentality,” Reeves said. Lockheed plans to conduct two successful flight tests before going into production, Reeves said, which as an MDA program requirement. “The time is right now,” Reeves said. “We have significant investments and the technology a couple of decades ago, when this was initially a vision of MDA, wasn't quite there, but now it is ready to go.” The company plans to take elements from its existing capabilities such as the Terminal High Altitude Area Defense (THAAD) system, which Reeves said has had a 100 percent mission success rate, and the Aegis missile defense system. Lockheed also will garner experience from its partnership with the U.S. Navy on its Trident II submarine-launched ballistic missile system, which “has to survive these more hostile environments,” she said. And Lockheed's experience with space is another asset that will contribute to understanding technology needed for an NGI, which will need to travel through space, according to Reeves. Lockheed is also optimistic, Reeves said, that it can meet a faster schedule for NGI than currently planned. Some Defense Department officials said NGI could not be fielded until the 2030s but the MDA director and U.S. Northern Command's commander believe it is possible to move that timeline to at least 2028 or earlier. The company plans to use tools such as artificial intelligence, machine-to-machine learning, big data analytics and 3-D printing to “accelerate the schedule and to deliver products faster than we have had in the past,” Reeves said. https://www.defensenews.com/industry/2020/08/03/lockheed-dives-into-next-generation-missile-defense-interceptor-competition
