  Five F-35 issues have been downgraded, but they remain unsolved

  By: Aaron Mehta , Valerie Insinna , and David B. Larter WASHINGTON — The F-35 Joint Program Office has put in place stopgap fixes for five key technical flaws plaguing America's top-end fighter jet, but the problems have not been completely eliminated. Last June, Defense News reported exclusive details about 13 major technical issues, known as category 1 deficiencies, impacting the F-35. The JPO has since quietly downgraded five of those issues to the lesser category 2. A category 1 deficiency is defined as a shortfall that could cause death, severe injury or illness; could cause loss or damage to the aircraft or its equipment; critically restricts the operator's ability to be ready for combat; prevents the jet from performing well enough to accomplish primary or secondary missions; results in a work stoppage at the production line; or blocks mission-critical test points. In comparison, a category 2 deficiency is of lesser concern — something that requires monitoring, but not something that should impact operations. But downgrading the category doesn't mean the problems are solved, said Dan Grazier, who tracks military issues for the Project on Government Oversight. CAT 2 programs are still "definitely cause for concern. They are going to have an impact on how the aircraft performs,” Grazier said. "It really depends on what the issue is, but every design flaw has a potential issue on the mission. ... You want to not have flaws, you want these things can be fixed so pilots can get out and do what they need to do.” Aside from a few basic statements on which projects were downgraded to CAT 2, a JPO spokesperson said the office “cannot disclose any information about how these deficiencies were resolved or downgraded due to their security classification.” The ALIS sovereign data transfer solution does not meet information assurance requirements. The Autonomic Logistics Information System, or ALIS, provides the backbone of the F-35, used by the aircraft's operators in virtually all stages of flying and sustaining the Joint Strike Fighter. The system is used to plan and debrief missions, order spare parts, walk maintainers through repairs, and view technical data and work orders. (A potential replacement, named ODIN, is in the works.) But some international partners on the F-35 program have expressed concerns that data flowing through ALIS to the United States government — and to Lockheed Martin — could give both the U.S. military and the American defense contractor a window into that country's flight operations, including when and where its F-35s are flying. Those concerns were so high that two countries threatened to leave the program entirely if a fix was not quickly applied, according to the original documents viewed by Defense News. That fix is now in, according to the JPO, which said that on April 29, 2019, an update to ALIS included an initial version of a new Sovereign Data Management tool. “The SDM tool permits F-35 operators more control over the types of Prognostics and Health Management (PHM) data that are transferred to the F-35 Operations Center,” the JPO said. Incorrect inventory data for complex assemblies continues to result in grounding conditions. This particular deficiency involves supplies or components that, upon installation, are not actually listed and tracked in ALIS as designed. Those require specific, almost daily requests to software engineers to have data corrected in the system. While those requests can catch some problems, the issue is not always detected by the user. These “holes,” as the JPO calls them, do not collect data on how parts are used after installation, which means a part might be breaking down from heavy use. Yet, that part won't be flagged by ALIS as an at-risk piece. As a result, it's less likely that issues developing from wear and tear or a lack of replacement parts will be discovered until such an issue has become an acute problem, possibly leading to a grounding of the aircraft. The issue was downgraded to a CAT 2 deficiency on Jan. 13, 2020, “due to ALIS data quality improvements that have been made in the two years since this DR [deficiency report] was written,” according to the JPO. “The quality improvements have reduced the frequency and magnitude of issues that have impacted operational units' abilities to quickly release aircraft for flight following maintenance.” The F-35B and F-35C experienced incongruous lateral and longitudinal control response above a 20-degree angle of attack. One of the most eye-opening issues identified in the initial report was that the F-35B and F-35C models used by the Marine Corps and Navy become difficult to control when operating above a 20-degree angle of attack — which would be seen in the extreme maneuvers a pilot might use in a dogfight or while avoiding a missile. Pilots reported the aircraft experiencing unpredictable changes in pitch, as well as erratic yaw and rolling motions when coming in at that angle of attack.. “It has random oscillations, pitch and yaw issues above [its] 20-[degree angle of attack]," a longtime naval aviator told Defense News last year. "[So] if I had to perform the aircraft — if I had to maneuver to defeat a missile, maneuver to fight another aircraft, the plane could have issues moving. And if I turn around aggressively and get away from these guys and use the afterburner, [the horizontal tail and tail boom] start to melt or have issues.” The issue was important enough that it accounted for two CAT 1 issues, one each for the two variants impacted by the design issue. However, the JPO downgraded this issue to a CAT 2 on May 28, 2019, for the F-35C and on July 8, 2019, for the F-35B. The solution involves “improvements in flying qualities that were implemented in software. The improvements provide pilots with an intuitive reference indication for AOA [angle of attack], which allows pilots to more quickly optimize lateral maneuvering during air-to-air maneuvering. These software improvements have been released to all F-35 operators.” There were unanticipated thrust limits in jetborne flight on hot days. This particular issue only occurred once, but was so significant that it was identified in the original document as the “No. 1 priority” for the Marine Corps. The issue was identified aboard the amphibious assault ship Essex, where a Marine pilot performed what is known as a “mode four” operation. That is where the jet enters hover mode near a landing spot, slides over to a target area and then vertically lands onto the ship. It's a key capability for the "B" model, which was designed for its short-takeoff-and-vertical-landing abilities. The engine — working hard on a day that temperatures cracked 90 degrees Fahrenheit while trying to lift a plane that was heavier than most returning to base — wouldn't generate the needed thrust for a safe, ideal landing. The pilot managed to land, but the issue set off alarm bells in the Marine aviation community. The JPO initially expected a fix for this issue to be out sometime in 2019, but it wasn't until March 2020 that a mix of nondescript “software updates and procedural adjustments” brought the “propulsion system performance back to original specified performance levels.” https://www.defensenews.com/smr/hidden-troubles-f35/2020/04/24/five-f-35-issues-have-been-downgraded-but-they-remain-unsolved/

  How the US Air Force is assembling its northernmost F-35 squadron amid a pandemic

  By: Valerie Insinna WASHINGTON — The COVID-19 pandemic could make it more difficult for the U.S. Air Force's newest F-35 squadron to organize its personnel and jets on schedule. On April 21, the 356th Fighter Squadron at Eielson Air Force Base, Alaska, became the service's northernmost fighter squadron after receiving its first two F-35s. Pilots began flying those jets for training three days later, and another four F-35s on loan from Hill Air Force Base in Utah flew to Alaska on April 27. But a couple key challenges could hamper the assemblage of the new squadron, said Col. Benjamin Bishop, commander of the base's 354th Fighter Wing. “We're actually on timeline,” he told Defense News in an exclusive interview on April 28. “We have the pilots and maintainers already here to support operations throughout the summer. However, as you know, the Department of Defense has put a stop-movement order through [June 30], and that is something we're working through on a case-by-case basis.” Under the current order, pilots and maintainers who are moving through the training pipeline have been granted a blanket exception to transfer to Eielson. But more experienced pilots, maintainers and support personnel coming from an operational base like Hill Air Force Base will need to receive an exception. Getting additional F-35s to Eielson could also be an obstacle, as Lockheed Martin assesses whether it must slow down deliveries of the F-35 due to disruptions to its supply chain. In a statement to Defense News, Lockheed spokesman Brett Ashworth could not say whether the company was on track to deliver F-35s to Eielson on schedule. “Lockheed Martin continues to work with our suppliers daily to determine the impacts of COVID-19 on F-35 production,” he said. “We are analyzing impacts at this time and should have more detail in the coming weeks.” If the coronavirus pandemic delays the pace of F-35 deliveries to Eielson, the squadron will have to mitigate the shortfall in jets, Bishop said. “Currently, we're at a good pace on the road to readiness for our F-35 program here, and we'll continue to adapt and adjust to bring this mission capability to its full potential in the Indo-Pacific theater,” he noted. Despite COVID-19 and the potential logistical challenges involved in sending people and F-35s to Eielson, day-to-day training operations have continued as normal, said Col. James Christensen, 356th Fighter Squadron commander. Having six F-35s on base allows maintainers to use the jets for training while also maximizing flight hours for the eight pilots currently in the 356th. “We still do the mission the way we always have. We have the masks and the wipe procedures and social distancing,” Christensen said. “So [we're] being creative but still being able to get the mission done.” There are strategic benefits to being the U.S. Air Force's northernmost fighter squadron, starting with access. With support from an aerial refueling tanker, the F-35s at Eielson can reach and target any location in Europe or the Asia-Pacific, Bishop said. And even the harsh climate of Eielson has its perks. It's a short flight away from the Joint Pacific Alaska Range Complex, the Defense Department's largest instrumented training range, with 77,000 square miles of airspace, according to the 354th Fighter Wing. “The F-35 is going to be able to fly in that airspace, but they're not going to be alone,” Bishop said. F-35s training in that area will regularly be joined by F-22s based at Joint Base Elmendorf-Richardson in Anchorage, as well as the F-16s in Eielson's 18th Aggressor Squadron that simulate enemy combat jets. “You're going to see amazing fifth-generation tactics and integration tactics emerge,” he said. Russia is investing in its Arctic infrastructure, and the U.S. military must make its own improvements to how it operates from and trains in the region, said Gen. Terrence O'Shaughnessy, who leads U.S. Northern Command and the North American Aerospace Defense Command. “It's great to see some of the additional forces that are going in, whether it's the F-35s going to Eielson, whether it's the work of the Coast Guard to develop icebreakers,” he said during a May 4 event. “These are all relevant things for us to be able to operate in the Arctic. And that is absolutely, to me, key to our ability to defend ourselves.” As the 356th stands up and becomes combat-ready, it will participate in the next Red Flag-Alaska, a multinational air-to-air combat training exercise slated to be held this August. The squadron is also looking for opportunities to deploy around the Asia-Pacific so that pilots can acclimate themselves to the long geographical distances that characterize the region, Christensen said. “Everyone is excited just to have F-35s here because of the awesome training we can do, but we're also thinking about at some point we have to project this air power out into the Indo-Pacific theater as a combat force. And transitioning everyone, including the wing and including [Pacific Air Forces] — they all have to adjust the mission of Eielson,” he said. Unlike other fighter bases, which usually swap out existing aircraft of existing squadrons with new jets, the two F-35 squadrons coming to Eielson aren't replacing anything, and infrastructure needs to be built to accommodate the anticipated growth in both people and aircraft. When the first members of the 356th Fighter Squadron arrived on base in July 2019, Eielson was home to about 1,750 active-duty personnel, Bishop said. By December 2021, that number is expected to double, with the addition of about 1,500 airmen. In that time, 54 F-35s will be delivered to the base for a total of two squadrons — a notable increase from the 30 F-16s and KC-135s previously at Eielson. An estimated $500 million will be spent on military construction to support the buildup at Eielson, including new operations buildings, a simulator building, heated hangars and other maintenance facilities, and a new cafeteria. A total of 41 facilities will be either built or refurbished with that funding, with 29 of those projects finished and others still under construction to support a second F-35 squadron, Bishop said. And everything — from constructing new facilities to maintaining runways — is tougher in the subzero temperatures of the Arctic. “Early on in this job, I learned that there are two seasons in Alaska,” Bishop said. “There's winter and construction season, with the former a lot longer than the latter. From a beddown perspective, how you put your construction plan together, you have to maneuver around that season.” “In order to maintain efficiency of fighter operations up here, one of the things we did is we built walled weather shelters for our aircraft, so all of our aircraft are actually housed in weather shelters," he added. "That's not necessarily for the aircraft. That's more for the maintainers because having that insulated and heating facility, now you can do maintenance around the clock.” Corrected at 5/12/20 at 2:53 p.m. with the correct size of the JPARC, which was recently expanded to 77,000 square miles of airspace. https://www.defensenews.com/smr/frozen-pathways/2020/05/11/how-the-us-air-force-is-assembling-its-northernmost-f-35-squadron-amid-a-pandemic/
