The Pentagon is battling the clock to fix serious, unreported F-35 problems

By:

WASHINGTON — Over the past several years, U.S. Defense Department leaders have gone from citing technical problems as their biggest concern for the F-35 program to bemoaning the expense of buying and sustaining the aircraft.

But the reality may be worse. According to documents exclusively obtained by Defense News, the F-35 continues to be marred by flaws and glitches that, if left unfixed, could create risks to pilot safety and call into question the fighter jet's ability to accomplish key parts of its mission:

F-35B and F-35C pilots, compelled to observe limitations on airspeed to avoid damage to the F-35's airframe or stealth coating. Cockpit pressure spikes that cause “excruciating” ear and sinus pain. Issues with the helmet-mounted display and night vision camera that contribute to the difficulty of landing the F-35C on an aircraft carrier.

These are some of the problems with the jet that the documents describe as category 1 deficiencies — the designation given to major flaws that impact safety or mission effectiveness.

Thirteen of the most serious flaws are described in detail, including the circumstances associated with each issue, how it impacts F-35 operations and the Defense Department's plans to ameliorate it.

All but a couple of these problems have escaped intense scrutiny by Congress and the media. A few others have been briefly alluded to in reports by government watchdog groups.

But the majority of these problems have not been publicly disclosed, exposing a lack of transparency about the limitations of the Defense Department's most expensive and high-profile weapons system.

These problems impact far more operators than the U.S. Air Force, Marine Corps and Navy customer base. Eleven countries — Australia, Belgium, Denmark, Italy, Israel, the Netherlands, Norway, Japan, South Korea, Turkey and the United Kingdom — have all selected the aircraft as their future fighter of choice, and nine partner nations have contributed funds to the development of the F-35.

Taken together, these documents provide evidence that the F-35 program is still grappling with serious technical problems, even as it finds itself in a key transitional moment.

And the clock is ticking. By the end of 2019, Defense Department leaders are set to make a critical decision on whether to shut the door on the F-35's development stage and move forward with full-rate production. During this period, the yearly production rate will skyrocket from the 91 jets manufactured by Lockheed Martin in 2018 to upward of 160 by 2023.

Generally speaking, the department's policy calls for all deficiencies to be closed before full-rate production starts. This is meant to cut down on expensive retrofits needed to bring existing planes to standard.

The F-35 Joint Program Office appears to be making fast progress, but not all problems will be solved before the full-rate production decision, said Vice Adm. Mat Winter, the Defense Department's F-35 program executive.

“None of them, right now, are against any of the design, any of the hardware or any of the manufacturing of the aircraft, which is what the full-rate production decision is for,” he told Defense News in an interview. “There are no discrepancies that put at risk a decision of the department to approve us to go into full-rate production.”

Nine out of 13 problems will likely either be corrected or downgraded to category 2 status before the Pentagon determines whether to start full-rate production, and two will be adjudicated in future software builds, Winter said.

However, the F-35 program office has no intention of correcting two of the problems addressed in the documents, with the department opting to accept additional risk.

Winter maintains that none of the issues represent any serious or catastrophic risk to pilots, the mission or the F-35 airframe. After being contacted by Defense News, the program office created two designations of category 1 problems to highlight the difference between issues that would qualify as an emergency and others that are more minor in nature.

“CAT 1-As are loss of life, potential loss of life, loss of material aircraft. Those have to be adjudicated, have to be corrected within hours, days. We have no CAT 1-A deficiencies,” Winter said.

Instead, the deficiencies on the books all fall under category 1B, which represents problems “that have a mission impact with a current workaround that's acceptable to the war fighter with the knowledge that we will be able to correct that deficiency at some future time,” Winter added.

Greg Ulmer, Lockheed Martin's vice president for the F-35 program, said currently fielded F-35s are meeting or exceeding performance specifications.

“These issues are important to address, and each is well understood, resolved or on a path to resolution," he said. "We've worked collaboratively with our customers, and we are fully confident in the F-35's performance and the solutions in place to address each of the items identified.”

    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/

    Le budget défense atteindra près de 41 milliards d'euros en 2022

    L'enveloppe budgétaire allouée à la défense en 2022 sera de nouveau en hausse pour atteindre près de 41 milliards d'euros, comme prévu par la Loi de programmation militaire (LPM), contre 39,2 milliards d'euros en 2021, a indiqué lundi la ministre des Armées, Florence Parly, lors de son discours de rentrée devant les personnels du ministère. « Depuis 2017, ce sont 26 milliards d'euros de plus qui auront été investis dans notre défense et nos armées. C'est considérable. C'est même historique. Et c'était nécessaire », a-t-elle souligné. D'une enveloppe globale de 295 milliards d'euros sur sept ans, la LPM 2019-2025 prévoit une nette hausse du budget défense après des années de déflation. Les hausses les plus importantes (+3 milliards par an) sont prévues à partir de 2023. « Il faudra continuer à se battre jusqu'au bout de cette Loi de programmation militaire qui doit nous emmener jusqu'en 2025 », a insisté Florence Parly.

    From the Spider to the Griffo, Leonardo launches radar and comms systems

    By: Andrew C. Jarocki WASHINGTON--Leonardo announced a host of new defense systems, including a communications intelligence system and a radar array. The Italian contractor unveiled the new offerings at the 2018 Farnborough Air Show in the U.K. The ‘Spider' communications intelligence system promises to “detect, intercept, identify and geo-locate complex target communcations” in real time, according to the company. The array, designed to fit on drones or manned aircraft, weighs less than 20kg (44 lbs) and fits in a 1.5 x 0.5 x 0.5m pod. The Griffo E-Scan system, the latest model of electronically-scanning radars, uses a matrix of hundreds of tiny radar modules to ‘steer' an electronic beam, rather than the radar physically moving to point a beam at a target. This allows the beam to move quickly and for “the radar to perform multiple tasks simultaneously" according to a company announcement. https://www.defensenews.com/digital-show-dailies/farnborough/2018/07/16/from-the-spider-to-the-griffo-leonardo-launches-radar-and-comms-systems/
