    COVID-19 Won’t Slow New Army Weapons: McCarthy, Murray, Jette

    While some prototype deliveries and field tests are being delayed, Army leaders said, there's enough slack in the schedule that combat units will still get the new tech on time. By SYDNEY J. FREEDBERG JR.on April 23, 2020 at 2:40 PM WASHINGTON: The Army and its contractors are coping with the COVID-19 pandemic so well that the service expects no delay in the fielding of future weapons, the Army Secretary and his two top modernization officials told reporters today. The “rigorous” review of acquisition programs for the 2022 budget request is also still on schedule, Sec. Ryan McCarthy said. “It's just amazing how quickly they've adapted, kept their workforce engaged, and are protecting cost, schedule, and performance on these weapons systems,” said McCarthy, recently returned from a visit to BAE and General Dynamics facilities in Detroit. “Also I'm very proud of Dr. Jette's and Gen. Murray's performance during this crisis, working on things like progress payments for manufacturers, trying to help them get access to small business loans, the managing of second- and third-tier suppliers.” “Right now, all the companies that were closed for any period of time are reopened,” said Assistant Secretary Bruce Jette, the service's civilian acquisition chief. One BAE worker was infected, resulting in a week-long shutdown of a combat vehicle assembly line – you can't weld armor plate over your telephone, Jette noted – but the company has now restarted production with new precautions in place. The company and the union have agreed to give up their traditional week-long shutdown for summer vacation to catch up. The Boeing CH-47 helicopter plant in Philadelphia also shut down for 10 days, Jette reported, but they're back up and running as well. He's most worried about smaller subcontractors, where a single COVID-19 case can force the entire workforce to be quarantined for 14 days, so he's tracking that closely. “I keep track on a daily basis of 63 pages of supply chain [data],” Jette said. “Our industry partners have been really good about opening their books all the way down to their sub-suppliers and keeping us well-informed — they contractually don't have to do that but they have.” Some deliveries of prototypes have been delayed, said Gen. John “Mike” Murray, chief of Army Futures Command. But, so far, those delays are measured in weeks and there's sufficient slack in schedules to catch up later this year, he said, which means programs will proceed to production and fielding on time. What's particularly tricky for the Army is that, after decades of dumping “good ideas” on soldiers only to find they didn't actually work, it's now systematically letting soldiers try out prototypes hands-on. These soldier touchpoints require troops to work together in the field, often side-by-side with contractors who record their feedback and make some fixes on the spot. That's difficult given pandemic precautions – but not impossible. Other types of testing allow a little more social distance, and work from engineering design to budget reviews can take place entirely online. Gen. Murray gave a rundown of key programs: The next flight test of Lockheed Martin's Precision Strike Missile (PrSM) will take place as scheduled on April 30th, Gen. Murray said. “I'm very confident,” he declared, to the point he's already planned his flight to go observe. On the other hand, the third big soldier touchpoint test for the IVAS targeting goggles, scheduled for this summer, has been delayed to the fall. That's not just because of social distancing, Murray said, but also because a Microsoft subcontractor ran into COVID-19 problems (they'll be back in operation this week). Because this would have been the first test of a fully militarized and ruggedized “form factor” of IVAS, which began life as a modified Microsoft HoloLens, it's too important to cut corners, he said. The program will be able to make up the lost time and deliver the final production version to troops on schedule, he said. There's been a six week delay in delivery of the three competiting prototypes for Next Generation Squad Weapon, meant to replace the M249 SAW. Once the weapons arrive, however, the Army will now get them into soldiers' hands in just two weeks, a month faster than originally planned, making up for most of that lost time. Field-testing of one contender for the new FTUAS drone is already underway at Fort Riley, as we've previously reported. Testing of another drone design at Fort Campbell is “a little bit delayed,” Murray said, but should start by the end of the month. The Limited User Test of the IBCS missile defense network has been postponed (again, as we've reported). But the equipment remains in place at White Sands Missile Range in New Mexico, Murray said, software updates continue, and the soldiers who spent months training to operate it will be back to do the test “this summer or early fall.” (The Army also previously announced it would postpone field tests of promising new Robotic Combat Vehicles). “In general,” Jette said, “we don't see any FUEs changing”: That's military jargon for “First Unit Equipped,” the crucial moment when enough of a weapon has been built to equip a significant combat unit. “We are tracking each program,” Jette said, not just the service's top priorities “but all of our over 600 programs, [and] none of them are at risk” of a delay so severe they can't recover. https://breakingdefense.com/2020/04/covid-19-wont-slow-new-army-weapons-mccarthy-murray-jette/

  • The US Air Force Is Adding Algorithms to Predict When Planes Will Break

    The US Air Force Is Adding Algorithms to Predict When Planes Will Break

    The airlines already use predictive maintenance technology. Now the service's materiel chief says it's a “must-do for us.” The U.S. Air Force has started to use algorithms to predict when its aircraft will break, part of an effort to minimize the time and money they consume in the repair shop. The use of predictive analytics has been blazed by airlines, which monitor their fleets' parts in an effort to replace broken components just before — and crucially, not after — they break. “I believe it is a must-do for us,” said Gen. Ellen Pawlikowski, the head of Air Force Materiel Command, the arm of the Air Force that oversees the maintenance of its planes. She spoke Tuesday at a Defense Writers Group breakfast in Washington. “We see this as a huge benefit.” If the Air Force could reduce the risk of unexpected breakage — and the attendant need to fly replacement parts and repair crews around the globe — it could reduce costs and boost mission effectiveness. It could also increase the usefulness of the current fleet by reducing the number of aircraft that need to be be held in reserve as backups. It starts with gathering data, such as the temperature of engine parts or the stresses on the airframe. “We are trying to leverage what we already get off of airplanes, as opposed to trying to go in and put instruments in places,” Pawlikowski said. “It turns out there's quite a bit that's there, but it may not be a direct measurement. In order to measure the temperature in this one particular spot, I'm getting information somewhere else.” Artificial intelligence and machine learning can then determine patterns. The general said the Air Force has been learning a lot from Delta, the world's second-largest commercial airline. “Delta has demonstrated the effectiveness of predictive maintenance in dramatically reducing the number of delays to flights due to maintenance,” she said. Over the past three years, Air Mobility Command — the arm of the Air Force that oversees all of its large cargo planes and aerial refueling tankers — has been organizing the data it collects on some of its planes. It has started using the predictive maintenance technology on its massive C-5 airlifters. The Air Force is also using the technology on the B-1 bomber. “The B-1 is an airplane that we actually bought with a whole bunch of data that we weren't using,” Pawlikowski said. “We started to take that data in and start to analyze it....We're very excited about this because we see huge potential to improve aircraft availability and drive down the cost.” She said she “was impressed when I saw some of the data that they were showing me.” The Air Force Lifecycle Management Center, which reports to Pawlikowski, has been funding these trials “by finding the loose change in the seat cushions,” she said. “As we have now shown some things ... we're seeing more and more interest in it and we're looking at increasing the investment in that to bring it further,” Pawlikowski said of the predictive maintenance. Last September, Gen. Carlton “Dewey” Everhart, head of Air Mobility Command, stressed his desire to use predictive maintenance, but warned it would cost money to get the datafrom the companies that make the planes. “In some cases, we'll be working this collaboratively with our industry partners,” Pawlikowski said Tuesday. “In other cases, we'll be doing it completely organically.” Air Mobility Command is also using predictive maintenance technology on the C-130J airlifter. The latest version of the venerable Lockheed Martin cargo plane — the J model — collects reams of data as it flies. In April, the Lockheed announced it was teaming with analytics firm SAS to crunch that data. “Everything we've been doing up to a certain point has been looking in the rear-view mirror with the data,” said Lockheed's Duane Szalwinski, a senior manager with his company's sustainment organization who specializes in analytics. “We're going to be able to look forward.” Lockheed is working on a six-month demonstration for Air Mobility Command; officials hope to be able to predict when certain parts will break before a flight. “If we're able to do that, it kind of changes the game in how you maintain and operate a fleet,” Szalwinski said. The data will give military planners a wealth of information about their aircraft that could help determine the best aircraft to deploy. “All those things you now know you have insights as to what you will need at the next flight, so you act accordingly,” he said. “Once we prove that we understand the probability of failure of these parts ... all things then become possible,” Szalwinski said. “Now it's not a matter of if, it's a matter of when. And if you know when, you can start acting accordingly. It would be a gamechanger in the way you manage a fleet.” Lockheed also wants to use the predictive maintenance tech on the F-35 Joint Strike Fighter. “The beauty of this is that the toolsets that we're developing, the models, how we clean the data, how we build the models, how we build the algorithms, all of that is not unique to a platform,” Szalwinski said. Still, instituting predictive maintenance practices fleet-wide is not going to happen overnight, particularly as since it will take time to understand the data, Pawlikowski said. Using this technology will require a cultural shift among maintenance crews because they'll be replacing parts before they actually fail, Pawlikowski said. “One of the big benefits is the reduction in the amount of time the airmen on the flightline spends troubleshooting a broken part” because “we will take them off before they break,” she said. https://www.defenseone.com/business/2018/05/us-air-force-adding-algorithms-predict-when-planes-will-break/148234/
