  Most F-35s return to flight operations after fuel tube problem

  By: Valerie Insinna WASHINGTON — After a fuel tube problem sidelined all operational F-35 aircraft last week, more than 80 percent of jets have been cleared to return to flight, the F-35 joint program office stated Monday. In a Oct. 15 statement, the JPO confirmed that the U.S. services and international partners have completed inspections of their F-35 inventories for faulty fuel tubes. The aircraft that are not impacted by the bad tubes — which are a component in Pratt & Whitney's F135 engine — are back in flying status. “The F-35 Joint Program Office continues to work closely with the military services to prioritize fuel tube replacements using the current spares inventory,” the JPO said. “Pratt & Whitney is rapidly procuring more parts to minimize the overall repair timeline for the remaining jets. Current inventory will restore about half of the impacted jets to flight operations, and the remaining aircraft are expected to be cleared for flight over the coming weeks.” Last week, all U.S. and international F-35s were momentarily grounded to allow for an enterprise-wide fuel tube inspection. The review began as a result of an investigation into a Sept. 28 Marine Corps' F-35B crash near Marine Corps Air Station Beaufort in South Carolina — the first F-35 crash in the jet's history. It is still unclear exactly how the defective fuel tubes impact the jet's performance or how serious a safety threat they pose during flight operations. Joe DellaVedova, a spokesman for the JPO, declined to discuss the specific problems that led the program office to call for a fleetwide inspection, saying that details could not be released until the Marine Corps completes its accident investigation. Also still up in the air is whether the Pentagon or Pratt & Whitney will be stuck paying the tab for retrofitting the fleet. Spokesmen from the U.S. Air Force, Marine Corps and Navy declined to lay out exactly how many of their aircraft had been impacted by the faulty fuel tubes. However, as Lockheed Martin delivered its 300th F-35 in June, 20 percent of the operational F-35 fleet can be estimated to be about 60 aircraft across the U.S. and international operators. The JPO called the fuel tube problem an “isolated incident” that would not impact F-35 deliveries. A total of 91 F-35s are planned to be delivered to the U.S. military and foreign customers this year. “The primary goal following any mishap is the prevention of future incidents,” the office said. “We will take every measure to ensure safe operations while we deliver, sustain and modernize the F-35 for the warfighter and our defense partners.” The problem with the defective fuel tubes is the latest in a string of recent supply chain issues that have plagued F-35 prime contractor Lockheed Martin and engine manufacturer Pratt & Whitney, and comes as Defense Secretary Jim Mattis sent a memo directing the Air Force, Marine Corps and Navy to boost the F-35′s mission capable rate to 80 percent. The Pentagon halted F-35 deliveries in March amid disagreements over whether the department or Lockheed should foot the bill for retrofitting part of the fleet that had not received corrosion-preventing primer in certain fastener holes. Deliveries resumed in May once the parties hammered out an agreement — although it was never revealed to the public exactly how the expenses would be paid off. In 2016, certain F-35As were grounded after it was found that coolant lines inside the jets' fuel tanks were rimmed with faulty insulation, which was prone to disintegrating. https://www.defensenews.com/air/2018/10/15/most-f-35s-return-to-flight-operations-after-fuel-tube-problem

  How Lockheed Martin Is Trying To Link Everything on the Battlefield

  BY PATRICK TUCKER Experiment by experiment, the company is weaving aircraft, ground vehicles, satellites, and the rest into a network that will someday give commanders unprecedented decision-support options. The Pentagon's efforts to digitally connect everything on the battlefield is has a big challenge to overcome: getting disparate vehicles and weapons to share data. “The interoperability of various, different systems, that's really where we are struggling. We don't have that machine to machine connection to begin with,” Air Force Brig. Gen. David Kumashiro recently told the audience at last week's Defense One Outlook 2020 conference. Over the past several years, Lockheed Martin officials say they've been working to build those connections, piece by piece and plane by plane. They started by asking, “How would we go fight in 2030, 2045?” and then working backwards, J.D. Hammond, vice president of C4ISR systems, told reporters at one of the company's offices. The company began by asking “How would we go fight in 2030, 2045?” They started with an idea of the state they wanted to reach and then worked backward. In 2013, the company launched a project, dubbed Missouri, to link the stealthy F-22 and F-35 combat jets. The Air Force has announced that they are to test a similar link next month, but the Air Force is establishing more complete linkages, including new forms of secure radio linkagages using software defined radio, and also including other assets such as Valkyrie drones. In 2015, they launched Project Iguana, extending the datalinks to the high-flying U-2 spy plane, fourth-generation combat aircraft such as the F-16, and satellites. In February 2018, they conducted an experiment under DARPA's SoSITE program that added other aircraft and a ground station. In April, their RIOT experiment connectngi jets to ground vehicles. Experiment by experiment, Lockheed tried to “systematically work” to build the components of a larger network of networks, said Hammond. There are four experiments projects planned for next year: Mayhem, focusing on links for satellites; Edison, datalinks for the Navy; Brennan, aircraft and Army units; and Project CASTL, satellites and a “space tactical layer”. Ultimately, Lockheed wants all this to add up to a “virtualized cloud-based architecture.” Think of it like the branches of a tree. A handful of ships and planes might form one network. That will, in turn, connect to a larger network that would, in turn, would be connected to the larger JEDI cloud. “You end up with virtual private clouds on the edge with a computing architecture you could have on an aircraft, on a ship, or any of the deployed nodes,” said John Clark, Lockheed's vice president of intelligence-surveillance-reconnaissance and unmanned aerial systems. Most of the linked aircraft and ships in these experiments carry an Enterprise Mission Computer 2.0 — dubbed “Einstein box” after its abbreviation, EMC2 — that translates each platform's data into a shared protocol that can go out to the larger wireless network. Lockheed officials hope that bringing all these pieces together will enable a new sort of operating system for warfare. They showed journalists a new experimental battle management display to illustrate the concept. The system presents the operator with a list of effects, from devastating explosions to a quiet disabling of some enemy system; a list of available assets, including planes or drones; a map of targets; and recommendations for the best way to deliver effects to targets. As circumstances change — fuel gets low, ammunition is depleted, targets are destroyed, new enemy forces arrive, etc. — the system can send out alerts that a new plan is needed — or automatically update the plan with new instructions for pilots and drone operators. It all depends on how high the operator wants to set the autonomy. That vision is very different from the way mission tasking works today. Preston Dunlap, the chief architect of the Air Force, said at the Defense One Outlook 2020 conference, “Right now, our commanders are very limited in who they can assign to do certain” things. “More often than not, you have to assign someone because they happen to be in front of a specific place in front of a specific computer,” he said. Of course, realtime data sharing across platforms isn't a simple or clear-cut affair, even after successful experimentation. The years-long problems with Lockheed's Autonomic Logistics Information System, or ALIS, for the F-35 show how hard it can be simply to share data between operators and just one platform. The challenges of sharing data between multiple platforms, in the middle of battle in a highly contested airspace, are far larger. But commanders say they must try. “In terms of where our adversaries are,” Kumashiro said, U.S. forces have “a need to have this joint all-domain command-and-control system.” https://www.defenseone.com/technology/2019/11/how-lockheed-martin-trying-link-everything-battlefield/161355
