Joe Gould WASHINGTON ― U.S. Army officials told lawmakers Tuesday they are seeking a new 15-year, $16 billion strategy to modernize and automate the military's aging munitions plants following nearly a dozen worker deaths and injuries over recent years. In Tactical Air and Land Forces Subcommittee testimony, Army officials suggested workers who handle dangerous materials could be replaced by robotics and computers as part of their ambitious plan. The testimony came as lawmakers are deliberating over a proposed reshaping of the Pentagon's explosives oversight body, as part of the 2021 defense policy bill. “We're essentially making the explosives in a manner very much like we did in World War I in some cases, World War II in others,” Assistant Secretary of the Army for Acquisition, Logistics and Technology Bruce Jette told lawmakers. “We literally have people standing under machines that are full of 1,500 pounds of molten explosives, drooling it into artillery shells to fill them up, and then they push the carts away. We don't have automation, we don't have robotics.” Lawmakers described the ammunition industrial base as fragile because of its dependence on foreign sources of materials and because its aging facilities need of safety upgrades. (Munitions production facilities are contractor operated, with some owned by the government.) Army officials largely agreed, saying they rely on 55 foreign suppliers for certain equipment and materials ― such as a TNT-replacement 2,4-Dinitroanisole, which comes from India ― because costs, environmental regulations and legal liabilities make many of them harder to develop in the United States. The Army even relies on a small volume of detonators and pyrotechnics from China, Jette said. The Army is studying how to wean itself from foreign suppliers. At the same time, Jette has not ruled out supplies from Canada, Mexico and elsewhere, if a surge is needed, adding that he personally visited a South Korean factory that once supplied the U.S. with bullets at .50 caliber and below. Calling safety a top priority, Army officials said human handling of the energetics, explosives and acids associated with munitions can be replaced with “process automation or other technology solutions, freeing the workforce to focus on technical oversight.” More than 80 percent of major mishaps at munitions facilities were caused by human error, they said. “Three deaths in the last ten years on our facilities, two of them were related to the manufacturing process: We don't need to have that happen anymore,” Jette said. “I do not want to be the ASAALT and get another phone call that there's another death on something I could have provided the improvement to.” Jette said the 2017 death of Lake City Army Ammunition Plant worker Lawrence Bass, 55, “should not have occurred,” and that Bass ― killed while handling an explosive component called tetrazine ― was performing his duties in accordance with procedures. “His death is in fact a catalyst in transforming our approach, as opposed to modernizing under current circumstances. He should never have been in that close proximity where that event could have happened,” Jette said. “Should it happen with a machine, I can buy another machine.” Still, modernizing in the way Army officials seek would require Congress appropriate roughly $1 billion per year for 15 years, which is more than twice what the Army has asked over the last three years. It's an open question whether Congress would be as inclined to support the munitions productions facilities, if they support fewer jobs. “The idea of making it safer for workers, there's no doubt about that, but because these plants have grown up since the '40′s," said Tactical Air and Land Forces Subcommittee Chairman Donald Norcross, D-N.J. "You eliminate many of those jobs, there's potential of that support also going.” Asked what more industry could do to shoulder the cost of modernizing facilities, Jette suggested it would be better if the government made the investments upfront as industry would only pass the costs on later. “This is the United States military's industrial base for munitions. We need to own that, not have anything beholden IP-wise or any other way to the defense industry or any other supplier," Jette said. https://www.defensenews.com/congress/2020/09/22/after-munition-worker-deaths-army-floats-16-billion-plan-to-modernize-production/

By Oriana Pawlyk Robins Air Force Base has been selected to host an elite system that will fuse intelligence, surveillance and reconnaissance sensor data from around the world, the Air Force announced Wednesday. The Georgia base, which currently hosts the E-8C Joint Surveillance Target Attack Radar System aircraft, or JSTARS, will be home to the next-generation Advanced Battle Management System, the service said in a release. "We must adapt our capability to survive in the changed threat environment and move swiftly to advanced battlefield management and surveillance," said Air Force Secretary Heather Wilson. "The critical capabilities at Robins allow us to leverage key expertise and accelerate toward the network needed for contested environments." The ABMS is intended to replace the current JSTARS fleet, which will keep flying until the mid-to-late 2020s. The network, which fuses the data from hundreds of sensors to provide situational awareness for combatant commanders across the globe, will function "as [a] decentralized system that draws on all domains," said Air Force Chief of Staff Gen. David Goldfein. "This is an important step as we move forward with a resilient and survivable network to ensure we are ready to prevail against changing threats," Goldfein said in the release. The network will leverage air and space systems and will include "a fusion center and associated supporting activities," the service said. "In addition, the network will also include some remotely piloted aircraft at Robins with sensors capable of collecting and transmitting information from the battlefield." Officials have said RPAs such as MQ-9 Reaper aircraft would be used to plug into such a network for additional situational awareness. Sens. Johnny Isakson and David Perdue, both Republicans from Georgia, were optimistic but cautious about the announcement Wednesday. They have previously voiced concerns over the Air Force's plan to cancel the JSTARS recapitalization program in favor of the ABMS. "We welcome any and all new missions that the Air Force is willing to bring to Robins, and I will continue to work with the Air Force as the implementation of this plan proceeds," Isakson said in a joint statement with Perdue. "In the meantime, I urge Secretary Wilson to work with us to ensure that there will be no capabilities gap that could put our warfighters at risk during the transition to this new system." Perdue added, "This additional new mission at Robins will be critical to fulfilling President Trump's National Defense Strategy and provides for the new Advanced Battle Management System." Both senators in August said they were "alarmed" to find out earlier that month that the Air Force might pursue "alternative intelligence, surveillance and reconnaissance platforms" instead of procuring a JSTARS replacement. The service in 2016 launched a $6.9 billion request for proposal for the engineering, manufacturing and development phase of the upgraded aircraft. It had planned to buy 17 new aircraft. In February, during the Air Force's fiscal 2019 budget rollout briefing, service officials said they were scrapping the initiative. The current JSTARS fleet is capable of developing, detecting, locating and tracking moving targets on the ground. The Air Force on Wednesday said there is no intent to reduce manpower at Robins as it transitions to ABMS. Lawmakers want to ensure there is no capability gap for troops on the ground as the service moves from the E-8C to the ABMS system. In April, the House Armed Services tactical air and land forces subcommittee in its markup to the fiscal 2019 National Defense Authorization Act said it will cap funding for the ABMS program until the Air Force restores the JSTARS recapitalization contract. The HASC passed its version of the fiscal 2019 bill on May 10. But members of the Senate Armed Services Committee have hinted they are open to the Air Force's effort to invest in a more survivable system than the JSTARS, which could be shot down. "There's a recognition in the Senate bill that we don't want to retire aircraft too quickly before a replacement capability arises such that we end up with a gap," an SASC staffer told Defense News on May 30. But "we do not direct them to proceed with the recap out of concerns with survivability, which we share with the department." The Senate is poised to vote on the bill in coming weeks. https://www.military.com/dodbuzz/2018/06/07/air-forces-new-battle-management-system-will-be-based-robins.html
