  New US Army radios show anti-jam progress at network experiment

  Andrew Eversden WASHINGTON — The U.S. Army is seeing improvements in anti-jam capabilities in new radios crucial to securing manned-unmanned communications at its annual Network Modernization Experiment. At NetModX '20, which runs from late July to early October at Joint Base McGuire-Dix-Lakehurst in New Jersey, the Army's Combat Capabilities Development Command's C5ISR Center — or Command, Control, Communication, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance Center — is testing the resiliency of the new radios. The effort will help the service observe how they would perform in the field as the Army looks to partner humans and machines. Initial data from the event suggests the two companies involved — Silvus and Persistent Systems — have improved their radio capabilities from last year, specifically in regard to anti-jam, according to Daniel Duvak, chief of the C5ISR Center's Radio Frequency Communications division. But one major challenge is making the radios less detectable as the Army's tactical network team starts to focus on command post survivability — or reducing the electromagnetic signature of command post communications — while not sacrificing latency and throughput. “If you want to make it less detectable, you know oftentimes you have to trade off the throughput or the range or one of those other products,” Duvak said. “So that's the piece and the real technical challenge that they're continuing to work on over the next few months. We've seen progress that they've made in those areas, but that's the piece that they're still working on.” Robert Stevens, an electronics engineer at the Radio Frequency Communications division, told C4ISRNET that the radios are an important piece of the next-generation combat vehicle. And Duvak said the Army's tactical network modernization team — made up of the Network Cross-Functional Team and Program Executive Office Command, Control, Communications-Tactical — wants to use the radios as a mid-tier radio solution. The development and fielding of new science and technology projects can take more than five years; however, the Army wants to speed that up as it seeks to modernize systems in preparation for future conflicts with near-peer adversaries. At last year's Network Modernization Experiment, the C5ISR Center tested several vendors' radios to see where commercial technology stood. Alternative contracting options, like broad agency announcements as well as cooperative research and development agreements, have proved critical to quickening radio development. Under the contracting mechanisms, vendors and the Army have more flexibility to experiment with radios and make iterative modifications as requirements change. Duvak said this is different from how the Army did business years ago, when it would award yearslong contracts but eventually receive radios that no longer met current requirements. “What we were able to do at this program was, in just about a year and a half of development time, take a couple of those products that we saw that were very promising and we were able to add and actually fund vendors to enhance those radios with those resiliency features that we were just talking about for the contested environment,” Duvak said. “Things like making them anti-jam, or more difficult for the adversary to jam, making them more difficult for the adversary to detect or intercept our communications.” Duvak said the Army wants the new radio capabilities for Capability Set '23, a collection of new tactical network tools to be fielded to soldiers in fiscal 2023. The resiliency of communications is critical as the tactical network modernization team pivots to reduce the electronic signature of the service's command post under Capability Set '23. The team is looking to increase bandwidth and reduce latency as part of that set of tools. Preliminary design review for Capability Set '23 is scheduled for April next year. https://www.c4isrnet.com/battlefield-tech/it-networks/2020/09/21/new-us-army-radios-show-anti-jam-progress-at-network-experiment/

  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
