    The Pentagon has cut the number of serious F-35 technical flaws in half

    By: Valerie Insinna WASHINGTON — The U.S. Defense Department is slowly but surely whittling down the number of F-35 technical problems, with the fighter jet program's most serious issues decreasing from 13 to seven over the past year. In June 2019, Defense News published an investigation delving into the details of 13 previously unreported category 1 deficiencies — the designation given to major flaws that impact safety or mission effectiveness. Following the report, five of those 13 category 1 problems have been “closed,” meaning they were eliminated or sufficiently corrected. Five were downgraded to a lower level of deficiency after actions were taken to help mitigate negative effects, and three issues remain open and unsolved, according to the F-35 program executive office. Four additional CAT 1 problems have also since been added to the list, raising the total CAT 1 deficiencies to seven. The program office declined to provide additional details about those issues for classification reasons, but stated that software updates should allow all of them to be closed by the end of 2020. “The F-35 Lightning II Joint Program Office is keenly aware of these existing F-35-related category 1 deficiencies and is focused on developing and implementing solutions for these issues as quickly as possible,” the program office said in response to questions from Defense News. “F-35 operator safety is the F-35 JPO's highest priority.” In a statement to Defense News, F-35 manufacturer Lockheed Martin confirmed the number of open category 1 deficiencies. However, the company declined to provide further information about the path to fix current issues or how earlier issues had been ameliorated. “We are actively addressing the deficiencies and expect all to be downgraded or closed this year,” the company said. While the overall reduction in deficiencies is a promising trend, it is also important to track how problems are solved and how quickly fixes are pushed to the rest of the fleet, said Dan Grazier, an analyst with the independent watchdog group Project on Government Oversight. “I'm not surprised that they are continuing to find issues. This is why we are supposed to be testing weapon systems before we buy a whole bunch of them. I am a little surprised that we are finding CAT 1 deficiencies at this point during operational testing,” Grazier said. “I think that speaks to the level of complexity with this program that it's taken us this long to get to this point, and even after all the testing that has been done and the time and money that has gone into this that we're still finding category 1 issues," he added. "It shows that the program wasn't born in the right place. It was way too ambitious from the very beginning.” Aside from four classified problems, there remain three open category 1 deficiencies in need of a fix. There are myriad reasons for that, the program office stated. “Reasons for delayed issue closure vary according to the complexity of the solution and the availability of test assets needed to verify the solution,” the JPO said. “The U.S. services fund the F-35 program to address a prioritized set of DRs [deficiency reports], while at the same time, develop new capabilities. It is likely that some low-priority DRs will never be resolved because of their minor impact on F-35 fleet operations does not justify the cost of resolution." The F-35 program office provided some details on the path forward for resolving these technical flaws, but noted that many details regarding those plans remain classified: Spikes in the F-35 cockpit's cabin pressure have been known to cause barotrauma, or extreme ear and sinus pain. This problem was documented when two Air Force pilots, flying older versions of the F-35A conventional-takeoff-and-landing model, experienced ear and sinus pain that they described as “excruciating, causing loss of in-flight situational awareness, with effects lasting for months,” according to documents obtained by Defense News. The physiological event is known by the medical term barotrauma. The F-35 Joint Program Office believes barotrauma in the jet is caused when sensors on the outer mold line of the aircraft detect “rapidly changing static pressures” that, in turn, drive very quick changes of the cockpit pressure regulator valve. Lockheed Martin has tested a fix that proved to be successful in a laboratory setting, Lockheed program head Greg Ulmer said last year. But flight testing of that improvement has not occurred, slowing the pace of a solution. The F-35 program office now says flight testing of a new cockpit pressure regulation system is planned for mid-2020. If all goes well, the deficiency should be completely eliminated in 2021. On nights with little starlight, the night vision camera sometimes displays green striations that make it difficult for all F-35 variants to see the horizon or to land on ships. On nights where there is little ambient light, horizontal green lines sometimes appear on the night vision camera feed, obscuring the horizon and making landing on a ship more dangerous. The problem is different than the notorious “green glow” issue, caused when the F-35 helmet-mounted display's LED lights produce a greenish luminescence that inhibits a pilot's ability to land on an aircraft carrier on nights with very little light. At one point, both Lockheed and the government's program office believed both problems could be solved by the F-35 Generation III helmet that the U.S. military began fielding last year. Although the program office no longer considers the “green glow” problem a deficiency, it appears that the new helmet did not completely solve the night vision camera issue. The program office told Defense News that it intends to develop software improvements and test them in flight later this year, but the deficiency will not be considered “closed” until at least 2021. The sea search mode of the F-35's radar only illuminates a small slice of the sea's surface. Unlike the other problems, which are the result of the contractor not meeting technical specifications or the jet not working as planned, this deficiency is on the books even though the jet's Northrop Grumman-made AN/APG-81 active electronically scanned array radar fulfills its requirements. Currently, the radar can only illuminate what is directly in front of it when in sea search mode. That performance is not good enough for the Navy, which wants to be able to search a wider area than is currently possible. Although this problem can be fixed with software modifications and an upgrade to the radar's processing power, it will continue to be on the books for some time. According to the program office, “[the] U.S. services agreed to plan for an improved radar mode, which will require the Technology Refresh-1 avionics update, for software release in [calendar year] 2024.” ‘A line in the sand' Although Defense Department and military leaders have criticized the F-35 program for high operations and sustainment costs, the operational community has rallied around the performance of the jet, praising its advanced computing capability that allows the aircraft to mesh together data from different sensors and provide a more complete picture of enemy threats. Brig. Gen. David Abba, who leads the Air Force's F-35 integration office, said in March that he was comfortable with the path forward to correct open deficiencies, downplaying the impact of those issues on daily operations. “Is it important to hold folks' feet to the fire and make sure that we're delivering on the capabilities that we need? Yes,” he said. But, he added, it's also difficult to balance the need to meet a stated technical requirement against the reality of a fielded technology that may already be performing well in daily operations. “That's the crux of the acquisition and the delivery problem that we have,” Abba said. “When we say ‘I need this to work exactly like this,' I'm drawing a line in the sand. If I'm a half degree on one side of that line versus the other, is it really that different? That's where the art comes in.” “We've got to kind of get over ourselves a little bit and acknowledge that we never field perfect weapon systems,” he continued. “I don't want to diminish the fact that it's critical that we get after open DRs, but every weapon system in the United States Air Force — and frankly around the planet — has open deficiencies. What matters is the severity of those deficiencies and ensuring that we have a robust process between government and industry to triage those and deal with them appropriately.” Aaron Mehta and David B. Larter contributed to this report. https://www.defensenews.com/smr/hidden-troubles-f35/2020/04/24/the-pentagon-has-cut-the-number-of-serious-f-35-technical-flaws-in-half/

    UK defense plans could take major hit from coronavirus fallout

    By: Andrew Chuter LONDON — Britain is facing some “distasteful medicine “ in an upcoming defense review, with question marks around money, allies, the industrial base, Defence Secretary Ben Wallace has warned. Giving evidence in a virtual session of the Parliamentary Defence Committee April 22, Wallace said there were some difficult issues to be addressed by a post COVID-19 Britain. “We will have to take some pretty distasteful medicine," he told committee members spread across the country in the first ever virtual session of the committee. "It's not just about sums of money. It is about cultural change — our relationship with our allies, what Britain's ambitions are going to be. Do we want to do everything? Do we want to do less? Do we want to let go of something? Do we want to bank on international consortia every time, or do we want to invest in our industrial base? All those are difficult questions. The defense secretary, who only recently recovered from COVID-19, said changing the culture is going to be as important as the sums of money made available to the Ministry of Defence in the integrated review. The government refers to it as an ‘integrated review' as it involves, defense, security, foreign policy and international development departments. Wallace said that whether the review is uncomfortable or not, his hope is the defense ministry will have a realistic amount of money available to undertake what it recommends. That's rarely been the case in previous reviews over the last 30 years or so, and few people here are expecting much different this time round. The issue is already complicated by the never-ending budget pressure at the MoD. According to the National Audit Office, the government's financial watchdog, the MoD already has a financial black hole for its equipment program of between £3 and £13 billion, or as much as $16 billion. John Louth, an independent defense analyst in the U.K., said one of the big challenges facing the MoD will be putting the procurement roadmap back together post COVID-19. “One of the real challenges will be re-profiling a schedule for procurement," Louth said. Everything is slipping to the right, and re-profiling is going to be difficult, particuarly as many of the programs are interdependent on other programs. That poses a large and difficult challenge within a restricted budget." The economic impact of the COVID-19 pandemic is likely to make more difficult allocation of cash to its various departments and ministeries in the next comprehensive spending review. That's not withstanding the fact that MoD personnel — nearly 3,000 at the last count — have been lauded for their excellent performance assisting the National Health Service and others, carrying out tasks ranging from delivering oxygen to hospitals to setting up and running command and control centers. In particular the MoD has been widely praised for rapidly constructing several field hospitals for COVID-19 sufferers, including a 4,000 bed facility at the Excel Centre in London. The site is well known to defense contractors, as it's the venue for the DSEI exhibition. The government announced last week it was pausing the integrated review to focus resources on the COVID-19 fight, without saying when the work would recommence. Wallace answered that question — twice. First he said the review would recommence next year; later he said the correct date was the end of this year, but he was seeking clarity on the exact timing. That decision will be taken by the Cabinet Office who are leading the review. They had previously ordered the review, which was initiated after Prime Minister Boris Johnson won the general election last December, be completed by July. That was a date many analysts and politicians, including the defense committee, thought was risky. “This [the delay] is welcome news. I want a longer period for the integrated review. I want us to examine our place in the world, especially post COVID. It's going to be a different world,” he said. Wallace, an ex-British Army officer, said the number one threat is lack of resilience. "I suspect it will be higher up the agenda as a result of the virus,” he said. The defense secretary said that unlike countries such as France, Britain wasn't bringing forward a number of programs to protect the industrial base. “We are though speaking to industry to ensure their cash flow is continuing. There is a lot of work on the books that we would like to keep going,” he told the committee. One industry executive who asked not to be named said, “cash is not an issue yet, but I'm prepared for that to happen. I'm bracing for extended credit being taken by our customers, but I haven't seen it yet.” The virus has had an impact on a number of major defense programs in the U.K., as people have been ordered to work at home or, if that's not possible, adopt social distancing requirements in the workplace. The impact that might have on defense suppliers ability to meet their contractual obligations, and subsequently their financial viability and and that of the supply chain, has been recognized by the government . A series of actions relating to paying suppliers has been in place since late March, with MoD procurement authorities advised to support suppliers in a range of ways to maintain cash flow. This includes forward ordering, payment in advance, interim payments and payment on order rather than receipt. The scheme has been well received by industry here. The executive said he applauded the government for its swift action, but acknowledged the challenge remains for protecting employment and cash flow. The executive did say though that more clarity was needed from the government over the availability of initiatives like the Corona Business Interruption Loan scheme for defense exporters. Wallace named BAE's F-35 and nuclear submarine activities as programs where the balance between COVID restrictions to keep workers safe and keeping production and cash flow moving were vital. “It's really important that we continue some work that's absolutely key. We also need to help these firms to get through the process, because cash flow is really important to their survival,” said Wallace. But it's not easy keeping your distance from colleagues if you are trying to build something like a nuclear submarine. As such, Wallace said submarine building activities in the U.K. had some of the highest absentee rates in the sector. BAE employs around 9,000 people at its nuclear submarine yard at Barrow in northwest England where it is building Astute-class attack submarines and working on the Dreadnought class of Trident nuclear missile boats. About 4,000 of the staff are working from home with over 1,100 employees now working on site – up from 800-900 last week. A BAE spokesperson said the employees were supporting critical work at the yard. Last week the company reported that HMS Audacious, its latest attack submarine to be built for the Royal Navy, had left the yard and was heading to the submarine base on the Clyde in Scotland. https://www.defensenews.com/global/europe/2020/04/23/uk-defense-plans-could-take-major-hit-from-coronavirus-fallout/

  • The Pentagon wants to ‘reconsider’ its JEDI award decision

    The Pentagon wants to ‘reconsider’ its JEDI award decision

    By Andrew Eversden The Department of Defense requested 120 days to “reconsider certain aspects” of its decision to award its controversial enterprise contract to Microsoft. The request from the DoD in a March 12 court filing comes after Court of Federal Claims Judge Patricia Campbell-Smith issued a temporary restraining order directing the Pentagon to stop all work on its Joint Enterprise Defense Infrastructure cloud contract, after AWS alleged that the DoD made mistakes in its source selection process. The court granted Amazon's request for an injunction Feb. 13. While Amazon challenged both the technical evaluation and political interference, the court's decision to impose the injunction rested on AWS' technical challenges to the DoD selection, which included issues with how the Pentagon considered data storage capabilities. “DoD wishes to reconsider its evaluation of the technical aspects of Price Scenario 6, and intends to issue a solicitation amendment and to accept limited proposal revisions addressing the offerors' technical approach to that price scenario,” Defense Department lawyers wrote in the document. In the court filing, the DoD also said it wants to reconsider its evaluation of Microsoft and AWS' online marketplace offerings and “may conduct” clarifications with the two tech giants. The DoD will reconsider other technical challenges presented by AWS, but “does not intend to conduct discussions with offerors or to accept proposal revisions with respect to any aspect of the solicitation,” other than price scenario six of the RFP, which deals with storage capabilities. In a statement, Microsoft spokesperson Frank Shaw said the DoD made the “correct decision.” “However, we support their decision to reconsider a small number of factors as it is likely the fastest way to resolve all issues and quickly provide the needed modern technology to people across our armed forces. Throughout this process, we've focused on listening to the needs of the DoD, delivering the best product, and making sure nothing we did delayed the procurement process. We are not going to change this approach now," Shaw said. “Over two years the DoD reviewed dozens of factors and sub factors and found Microsoft equal or superior to AWS on every factor. We remain confident that Microsoft's proposal was technologically superior, continues to offer the best value, and is the right choice for the DoD.” The JEDI cloud contract is potentially worth $10 billion over 10 years. This court filing is another significant setback for the DoD, even after the continuous challenges the contract has faced for about two years. Earlier in the court battle, Amazon sought to depose President Donald Trump, Secretary of Defense Mark Esper, former Secretary of Defense Jim Mattis, DoD CIO Dana Deasy and several other DoD officials involved in the in the final decision. An Amazon spokesperson said the company was “pleased” with the decision. "We are pleased that the DoD has acknowledged ‘substantial and legitimate' issues that affected the JEDI award decision, and that corrective action is necessary,” a spokesperson said. "We look forward to complete, fair, and effective corrective action that fully insulates the re-evaluation from political influence and corrects the many issues affecting the initial flawed award.” https://www.federaltimes.com/it-networks/cloud/2020/03/13/the-pentagon-was-to-reconsider-its-jedi-award/
