Το γραφείο διακλαδικού προγράμματος (JPO) F-35 των Ηνωμένων Πολιτειών Αμερικής (ΗΠΑ) και η εταιρεία Lockheed Martin οριστικοποίησαν συμφωνία αξίας $34 δισεκατομμυρίων για την παραγωγή και παράδοση 478 διακλαδικών αεροσκαφών κρούσης F-35 στην χαμηλότερη τιμή σ’ όλη την ιστορία του προγράμματος. Η σύμβαση αυτή περιλαμβάνει όλα τα αεροσκάφη παρτίδων 12, 13 και 14 των διεθνών εταίρων και των Στρατιωτικών Πωλήσεων Εξωτερικού (FMS) των ΗΠΑ.

Στο πλαίσιο της συμφωνίας, η εταιρεία που κατασκευάζει το F-35 καλύπτει και υπερβαίνει τους δηλωμένους στόχους μείωσης κόστους για κάθε έκδοση – και η τιμή μονάδας F-35A, συμπεριλαμβανομένου κινητήρα και αεροσκάφους, πλέον βρίσκεται κάτω από τα $80 εκατομμύρια στις παρτίδες 13 και 14, το κόστος μονάδος για το F-35A παρουσιάζει την εκτιμώμενη συνολική μείωση του 12,8 τοις εκατό από το κόστος του αεροσκάφους συμβατικής προσγείωσης παρτίδας 11 και εξοικονόμηση κατά μέσο όρο 12,7 τοις εκατό και στις τρεις εκδόσεις των παρτίδων 11 έως 14.

«Η μείωση κόστος είναι σημαντική για την επιτυχία του προγράμματος. Είμαι ενθουσιασμένος που JPO F-35 και Lockheed Martin κατέληξαν σε συμφωνία για αυτήν την σύμβαση ορόσημο των τριών παρτίδων. Η συμφωνία αυτή επιτυγχάνει μείωση κόστους κατά μέσο όρο  12,7 τοις εκατό και στις τρεις εκδόσεις και μας πηγαίνει κάτω από τα $80 εκατ. για ένα F-35A της Αεροπορίας των ΗΠΑ της παρτίδας 13 – μια παρτίδα νωρίτερα από το προγραμματισμένο», δήλωσε ο Ερικ Φικ, Αντιπτέραρχος της Αεροπορίας των ΗΠΑ, εκτελεστικός διευθυντής προγράμματος F-35. «Η εν λόγω συμφωνία των $34 δισεκατομμυρίων είναι ένα πραγματικά ιστορικό ορόσημο για το εγχείρημα του F-35».

Η συμφωνία περιλαμβάνει 291 αεροσκάφη  για τους Κλάδους  των Ενόπλων Δυνάμεων των ΗΠΑ, 127 για τους διεθνείς εταίρους του F-35 και 60 για τους πελάτες FMS.

    «Εξαιρετική» απόφαση να αγοραστούν σχεδόν 1000 F-35 πριν καν ολοκληρωθούν οι ΑΡΧΙΚΕΣ επιχειρησιακές δοκιμές και αξιολόγηση (ΙΟΤ&Ε), με την χαώδη και διάσπαρτη γραμμή παραγωγής να μην μπορεί να ανταποκριθεί στην ζήτηση σε ανταλλακτικά για τον ήδη υπάρχοντα στόλο (backlog με 4300 ελλείψεις τον Αύγουστο), και με την διαμόρφωση Block 4 να έρχεται κάπου στα μέσα της επόμενης δεκαετίας με σκοπό α) να λύσει τεχνικά προβλήματα που δεν θα λυθούν στα block 3x β) να αναβαθμίσει κύρια υποσυστήματα του F-35 που μόνο «υπερσύγχρονα» δεν είναι μετά από 20 χρόνια (πχ. οθόνες, επεξεργαστές, EOTS, ALIS κ.α) και γ) να προσθέσει «εξωτικές» δυνατότητες όπως μεταφορά εξωτερικών ή σύμμορφων δεξαμενών καυσίμου, μεταφορά των Small Diameter Bombs (SDB) κ.α. 😀

    Όχι ότι με ενδιαφέρει η διατήρηση της ισχύος των ΗΠΑ, κάθε άλλο. Μάλιστα θεωρώ εξαιρετικά ταιριαστό αυτό που θα τους συμβεί με το F-35 μόλις τελειώσουν κάποια στιγμή τα ψέματα, και στοκάρω ποπ-κορν για το θέαμα. Γιαυτό και εύχομαι ολόψυχα καλές πωλήσεις στην Lockheed όταν πρόκειται για την USAF, το USN και τους US Marines.

    Αυτά 60 F-35 για πελάτες με χρηματοδότηση FMS με φοβίζουν. Φανταστείτε την ΠΑ να πετάει F-35 block 3x με κόστος $44.000 ανά ώρα πτήσης, εν μέσω ελλείψεων στην παραγωγή των πανάκριβων ανταλλακτικών, αεροσκάφη «πρώιμα» τα οποία θα πρέπει και να αναβαθμίσει σε block 4 για τις «πλήρεις δυνατότητες». Π.χ το USN έχει αναφέρει ανεπαρκείς/προβληματικές επιδόσεις στην έρευνα αέρος-επιφανείας στο ραντάρ του F-35 block 3x. Πότε αυτά θα λυθούν σύμφωνα με την LM; Στην έκδοση block 4. Και πάει λέγοντας.

    Γενικά μια αγορά F-35 των block 3x από την τόσο «εύπορη» χώρα μας θα αναδείξει στον υπερθετικό όλα τα «δυνατά» μας σημεία όσο αφορά τον γνωστό «προγραμματισμό» και την «προνοητικότητα» με την οποία διαχειριζόμαστε θέματα υποστήριξης, ανταλλακτικών και αναβαθμίσεων των μέσων της ΠΑ, Με άλλα λόγια, όλεθρος.

    Οι ίδιοι αμερικάνοι πολίτες που συνήθως είναι υπερήφανοι για τα προϊόντα που παράγουν οι εγχώριες εταιρίες, δεν έχουν πειστεί, η δεν μπορούν να ζεσταθούν για το αεροσκάφος/πρόγραμμα η να πιστέψουν ότι θα αποδόσει αυτά που έχουν συμφωνηθεί. Ίσως επειδή έχουν υπόψην τους προηγούμενες περιπτώσεις, με την εν λόγο εταιρία(που δεν το έχει με τα μαχητικά), εκτός απο εκείνους που έχουν οικονομικό συμφέρον απο αυτό το πρόγραμμα(για αυτό και επιμένουν προφανώς να παρατηρούν το ποτήρι μισό γεμάτο).

    The F-35 Stealth Fighter Still Isn’t Ready for High-Tech Combat: Report
    At least that’s what Dan Grazier claimed, citing 2018 data from the U.S. Defense Department’s Director of Operational Test and Evaluation. Grazier, a former Marine Corps officer, is an analyst with the Washington, D.C. Project on Government Oversight.

    March 20, 2019

    At least that’s what Dan Grazier claimed, citing 2018 data from the U.S. Defense Department’s Director of Operational Test and Evaluation. Grazier, a former Marine Corps officer, is an analyst with the Washington, D.C. Project on Government Oversight.

    Decades after its development began, 13 years after its first flight and four years after it first became operational, Lockheed Martin’s F-35 stealth fighter still isn’t ready for high-tech combat.

    At least that’s what Dan Grazier claimed, citing 2018 data from the U.S. Defense Department’s Director of Operational Test and Evaluation. Grazier, a former Marine Corps officer, is an analyst with the Washington, D.C. Project on Government Oversight.

    «The information that is provided by DOT&E shows that the F-35 is still in trouble in these vital areas,» Grazier wrote.

    Little or no improvement in the key availability, reliability and flying-hour metrics over the last several years means too few F-35s will likely be ready for combat when they are most needed, now or for the foreseeable future.

    During durability testing, the Marine and Navy F-35s have suffered so many cracks and received so many repairs and modifications that the test planes can’t complete their 8,000-hour life-expectancy tests. The Marine version’s airframe life could be so short that today’s F-35Bs might end up in the boneyard as early as 2026, 44 years before the program’s planned 2070 sunset.

    Despite years of patches and upgrades, the F-35’s most combat-crucial computer systems continue to malfunction, including the Autonomic Logistics Information System maintenance and parts ordering network; and the data links that display, combine and exchange target and threat information among fighters and intelligence sources.

    The program has not provided the resources necessary to build, test and validate the onboard mission-data files that control mission accomplishment and survival.

    As in previous years, cybersecurity testing shows that many previously confirmed F-35 vulnerabilities have not been fixed, meaning that enemy hackers could potentially shut down the ALIS network, steal secret data from the network and onboard computers and perhaps prevent the F-35 from flying or from accomplishing its missions.

    The all-important and much-delayed F-35 Initial Operational Test and Evaluation report—assessing whether the plane is combat-suitable and ready for full-scale production—may well not only be late (perhaps well into 2020), but may also be based on testing that is considerably less combat-realistic than planned.

    This is both because test personnel are forced to make do with incompletely developed, deficiency-laden planes, and the F-35 program has for years failed to fund adequate test-range hardware and realistic multi-aircraft, multi-threat simulation facilities.

    The F-35 joint program office all but dismissed the government report. “All of the issues mentioned are well known to the JPO, the U.S. services, our international partners and allies and our industry team and are being aggressively addressed,” the office stated.

    “The F-35 enterprise achieved numerous critical milestones during 2018 which have set a solid foundation for the program to complete Initial Operational Test and Evaluation and move into full rate production as planned in late 2019.”

    But Grazier isn’t alone in pointing out lingering problems with the F-35 program, which aims to replace most of the U.S. military’s roughly 3,000 fighters and attack planes with as many as 2,300 F-35s at a long-term cost of around $1 trillion.

    Acting defense secretary Patrick Shanahan, a former Boeing executive, reportedly described the F-35 program as «f—ed up.» Lockheed Martin «doesn’t know how to run a program,» Shanahan reportedly added.

    The U.S. Air Force in its 2020 budget request is proposing to buy the first up 144 upgraded F-15EX fighters from Boeing, potentially ending a nearly two-decade streak of only buying fighters that are stealthy and made by Lockheed.

    While the F-15 lacks radar-evading features, it is cheaper to operate than an F-35 is and can carry hypersonic weapons that are too big for an F-35 to handle and which require a fighter to reach speeds that are outside of an F-35’s performance envelope.

    Inside America’s Dysfunctional Trillion-Dollar Fighter-Jet Program
    By Valerie Insinna
    Aug. 21, 2019

    On the morning of June 23, 2014, an F-35 burst into flames just moments before its pilot was set to take off on a routine training mission. He heard a loud bang and felt the engine slow as warning indicators began flashing “fire” and other alerts signaled that systems in the plane were shutting down. Witnesses at Eglin Air Force Base near Pensacola, Fla., reported seeing the pilot escape from the cockpit and run away from the fighter jet, which was engulfed in thick plumes of black smoke. It was the first major mishap involving a F-35 Joint Strike Fighter, and it couldn’t have happened at a worse time.

    In less than a month, the F-35, America’s high-profile next-generation fighter jet, was poised to make its international debut in Britain at Farnborough Airshow, the second-largest event of its kind in the world. Officials from the Pentagon and the aircraft’s manufacturer, Lockheed Martin, had eagerly anticipated the opportunity to show off a working, flying F-35 after a decade of delays and spiraling cost overruns.

    The F-35 initiative is the Defense Department’s most expensive weapons program ever, expected to cost taxpayers more than $1 trillion over its 60-year lifespan. It’s also the United States military’s most ambitious international partnership, with eight other nations investing in the aircraft’s development. Its advocates promised that the jet would be a game-changing force in the future of war — so much was riding on its success that a program cancellation was not an option. And yet for years it seemed as if the F-35 might never make it beyond its development phase.

    Christopher Bogdan, the Air Force lieutenant general in charge of the program at the time of the fire, received a call about the incident within the hour. His first reaction was relief that it had been detected before takeoff, a stroke of good fortune that allowed the pilot to escape uninjured. “If that engine problem would have occurred 30 seconds, 60 seconds, two minutes later, that airplane would have been airborne,” Bogdan said in a recent interview. “Heaven knows what could have happened then.”

    An investigation of the incident determined that a fan blade in the jet’s engine had overheated from friction and cracked, throwing off fragments of metal that punched through the fuselage, severed hydraulic and fuel lines and ignited a spray of jet fuel. Officials couldn’t guarantee that other F-35s wouldn’t have the same problem, and they didn’t want to risk a potentially catastrophic fire during a trans-Atlantic flight. The F-35 never made it to Farnborough that year, and the public-relations coup that Pentagon and Lockheed officials had hoped for turned into another round of ammunition for the plane’s critics.

    It was one more bad news story for a controversial program that had been dogged by bad news.

    Slowly, though, the program and its reputation have improved over the ensuing five years. Lockheed has now delivered more than 400 planes to American and foreign militaries, and the unit cost per aircraft has dropped significantly. In 2018, the F-35 completed its first combat operation for the Marine Corps in Afghanistan. The Air Force used it for airstrikes in Iraq about six months later. Later this year or in early 2020, the F-35 will go into full-rate production, with Lockheed expected to churn out 130 to 160 or more planes per year, a huge step up from the 91 planes delivered in 2018. That production milestone will be a symbolic turning point for the program, evidence that major problems that plagued the Joint Strike Fighter in the past are now history.

    Yet even as the program plows forward, unresolved technical issues have continued to emerge. In June, my colleagues and I at Defense News reported that the plane still faced at least 13 severe technical deficiencies during operational testing, including spikes in cabin pressure, some rare instances of structural damage at supersonic speeds and unpredictability while conducting extreme maneuvers — all problems that could affect the pilot’s safety or jeopardize a mission’s success. At the same time, the F-35s already delivered to squadrons have introduced new complications: On military bases around the United States, the high cost of operating the aircraft, a shortage of spare parts and a challenging new approach to updating the jet’s crucial software code have program officials and military leaders urgently looking for solutions. Still, they assure the public that nothing will prevent the program from moving forward. It’s a stance that breaks with the advice of the Government Accountability Office, which advised that all serious problems should be resolved before transitioning to full-rate production.

    With the critical problems that once dominated both headlines and congressional hearings seemingly resolved, the F-35 may not be the high-profile problem child it once was. But the Pentagon’s efforts to play down new complications raise questions about whether America’s most controversial warplane is actually ready to move into its next phase and what kind of new problems might surface in that transition.

    The Joint Strike Fighter program was conceived in the 1990s as the most ambitious aircraft development effort in the Defense Department’s history. One company would oversee design and production of three different versions of an aircraft that could be operated by the United States Air Force, Navy and Marine Corps as well as America’s allies, who would help offset the development costs. The project would result in a technologically superior plane that would be manufactured in such large quantities that the jets would cost no more than the older planes it would replace.

    The jet was to replace a wide variety of the American military’s combat aircraft, including the Air Force’s F-16 Fighting Falcon and A-10 Thunderbolt II, the Marine Corps’s AV-8B Harrier and the F/A-18 Hornet operated by the Navy and Marine Corps. All of the services’ requirements for new fighter jets were combined into one program, which would be awarded to a single contractor. Like the Air Force’s F-22, this new fighter jet needed to be stealthy and able to fly at supersonic speeds. To meet the needs of the Marine Corps, it needed to land vertically on ships, while the Navy version would need larger wings and different landing gear so it could take off from and land on aircraft carriers.

    “If you were to go back to the year 2000 and somebody said, ‘I can build an airplane that is stealthy and has vertical takeoff and landing capabilities and can go supersonic,’ most people in the industry would have said that’s impossible,” said Tom Burbage, Lockheed’s general manager for the program from 2000 to 2013. “The technology to bring all of that together into a single platform was beyond the reach of industry at that time.”

    Lockheed Martin thought otherwise. In 2001, the defense company’s model — then called the X-35 — won against Boeing’s X-32 after both companies demonstrated working prototypes of a stealth fighter capable of hovering and vertical landings.

    There soon turned out to be an essential flaw in the grand plan for a single plane that could do everything. Design specifications demanded by one branch of the military would adversely impact the F-35’s performance in another area. “It turns out when you combine the requirements of the three services, what you end up with is the F-35, which is an aircraft that is in many ways suboptimal for what each of the services really want,” said Todd Harrison, an aerospace expert with the Center for Strategic and International Studies. “It is much more expensive than originally envisioned, and the three versions of the plane actually don’t have that much in common.”

    But early in the program, Lockheed Martin began construction with glowing optimism. The company decided to build the Air Force’s F-35A first because it was considered the simplest model, then move on to the difficulties of the F-35B short-takeoff and vertical-landing version and then the F-35C, which can land on an aircraft carrier — a decision that turned out to be a mistake. Once Lockheed’s engineers proceeded with the more demanding design of the F-35B, they found that their initial weight estimates were no longer accurate and the B model was on track to be 3,000 pounds too heavy to meet specifications. The company was forced to begin an extensive redesign project that added an 18-month delay to the program.

    Later, serious problems resulted from starting production while the aircraft was still under development, a process the Pentagon calls concurrency. The strategy was meant to allow the services to begin flying their F-35s sooner. Instead, F-35s started rolling off the production line with unresolved technical problems, forcing the Pentagon to continually retrofit even newly built jets.

    In 2010, the ballooning costs — which put the cost per plane more than 89 percent over the baseline estimate — triggered a breach of the Nunn-McCurdy Act, a law that forces the Pentagon and Congress to evaluate whether to cancel a troubled program. But because the F-35 was intended to replace so many legacy fighter jets, military leaders essentially had no choice but to keep going.

    One factor that kept sending the F-35 program off course was the level of control Lockheed exerted over the program. The company produces not only the F-35 itself but also the training gear for pilots and maintainence technicians, the aircraft’s logistics system and its support equipment, like carts and rigs. Lockheed also manages the supply chain and is responsible for much of the maintenance for the plane. This gave Lockheed significant power over almost every part of the F-35 enterprise. “I had a sense, after my first 90 days, that the government was not in charge of the program,” said Bogdan, who assumed oversight as the program’s executive officer in December 2012. It seemed “that all of the major decisions, whether they be technical, whether they be schedule, whether they be contractual, were really all being made by Lockheed Martin, and the program office was just kind of watching.”

    Bogdan particularly worried that Lockheed had too much control of the government’s test flights. The company was allowed to manage the test program and had the power, for example, to defer more challenging tests until later. In past programs, the government had controlled testing and had aimed to find any difficult, high-priority problems early, so they could be addressed as soon as possible. Bogdan also argued that the Pentagon’s program office was not transparent enough in letting the military services know how their money was being spent. Because Lockheed was not required to report its financials in detail, the program office itself did not have a clear picture of exactly how much an F-35 truly cost and how the money was being used.

    Costs and complications were spiraling. Someone needed to intervene before the Defense Department lost control entirely, Bogdan thought. In September 2012, when he was the program’s second-in-command, he took to the lectern at the Air Force’s largest conference and said something that had not been publicly acknowledged before: The relationship with Lockheed was the worst arrangement he had ever seen between the Pentagon and a defense contractor. The audience was shocked. At military conferences and trade shows, Defense Department officials and their contractors typically boast about their collaborative efforts. Instead, Bogdan publicly shamed the defense behemoth, criticizing the lagging production time and skyrocketing costs.

    At that point, there was a lot to rebuke. The Pentagon had restricted the F-35 from flying near thunderstorms after flight tests revealed that its lightning-protection system was deficient. That became easy fodder for skeptics, given the plane’s designation as the F-35 Lightning II. The jet’s cutting-edge helmet display, which melds imagery from the F-35’s multiple cameras and sensors into a single picture, didn’t work properly, with pilots experiencing a jittery, delayed video feed. And the jet’s software development had lagged behind schedule, leaving pilots stuck with an interim version that allowed only for basic training. When Bogdan was promoted to the top post as the program’s executive officer, a rule change empowered him to stay on past the previous two-year limit, and he let Lockheed know that he wasn’t going anywhere until the F-35’s major difficulties were behind it. The Pentagon and the contractor got to work on correcting the jet’s technical issues, one by one.

    Within a year, Bogdan was saying publicly that the relationship with Lockheed was improving and that the contractor was making progress in addressing the F-35’s problems, albeit more slowly than he would have liked. The program office and Lockheed had figured out some ways to cut the cost of manufacturing the fighter. More flight testing was happening. The lightning-protection system was redesigned in 2014, and the F-35 can now fly in bad weather. A series of hardware and software changes to the helmet have solved the image-quality problems.

    Still, as problems were fixed, new ones surfaced. In 2015, the program office found that the plane’s ejection seat could cause serious neck injuries to lightweight pilots, prompting the Air Force to ban pilots under 136 pounds from flight operations until a fix was implemented in 2016. Perhaps most damning was a 2015 report by War Is Boring, a well-read military blog, citing a document by an Air Force test pilot that asserted that the F-35 could not defeat the 1970s-era F-16 in aerial combat. If that was true, the staggeringly expensive high-tech jet was already obsolete before it would ever take to the skies in wartime. It emerged that the assessment was provisional and incomplete. The pilot had based his judgment on a single day’s mock aerial battle between an F-16 and an F-35 that temporarily had limited maneuverability and restricted performance because it had an early version of its software package. Nevertheless, the characterization of the F-35 as an overpriced but mediocre dogfighter has haunted it ever since.

    Though the F-35’s bad reputation among the public has persisted, the military has grown increasingly confident in the jet’s capabilities as problems have been eliminated and additional weapons and software have made the aircraft more capable in a fight. As more pilots log more flight time, they have raved about the F-35’s performance and technological advances.

    The Marine Corps, which began normal flying operations with the jet in 2015, became the first military branch to fly the F-35 in combat when it used the jets for airstrikes in Afghanistan last year. Both the Air Force and Navy are also now operating their own F-35s. In 2017, during the F-35A’s first outing in Red Flag, the Air Force’s largest training exercise for aerial warfare, the jet killed 20 aircraft for each F-35 shot down in simulated combat. In April, Air Force pilots took that training and put it into practice for the first time, using the F-35 in an airstrike against ISIS in Iraq.

    Pressure from Congress also helped shape the F-35 into a more successful program. In 2016, Senator John McCain of Arizona labeled the program a “scandal and a tragedy with respect to cost, schedule and performance.” Recognizing that it was nearly impossible to cancel the program, McCain nevertheless aimed to hold it accountable for its repeated setbacks. He moved forward with a carrot-and-stick approach, approving additional funding for the F-35 as chairman of the Senate Armed Services Committee while at the same time regularly grilling Defense Department officials during congressional hearings.

    Since McCain’s death last August, no other lawmaker has exacted that level of scrutiny. That’s by design, said Dan Grazier of the Project on Government Oversight, a watchdog organization that has repeatedly criticized the aircraft. “It’s no accident that there are more than 1,500 suppliers for the F-35 program, and they’re spread out to almost every state,” he said. “That means that there’s basically a veto-proof constituency bloc on Capitol Hill for the F-35 program, so it becomes very difficult for members of Congress to really criticize this program.” Legislators looking to relieve pressure on the program — and argue for increasing the number of aircraft purchased annually — have been able to point to measurable progress in the F-35’s performance and management. But that leniency comes at the expense of taxpayers’ dollars, say critics like Grazier, who want to see lawmakers do more to push for cost savings.

    Within the last few years, the Defense Department has corrected hundreds of Category 1 deficiencies, the label the Pentagon gives to serious technical problems including ones that could affect safety or mission effectiveness, and many of the F-35’s most visible problems have been resolved. However, as recently as June, at least 13 Category 1 deficiencies were still on the books. “Each is well understood, already resolved or on a near-term path to resolution,” Lockheed said in a statement. Vice Adm. Mat Winter, who led the Pentagon’s F-35 program office until July, maintained that the 13 deficiencies were not ones so serious that they could cause loss of life or aircraft. The department has a plan to fix all but two of the issues — the two have occurred only once during flight tests and are considered anomalous — and according to Winter, the problems will not affect the Pentagon’s plan to move to full-rate production.

    The F-35 was in the news again in July when the White House decided to expel Turkey from the program when that contentious ally refused to give up its plan to simultaneously acquire an advanced air defense system from Russia. That new partnership with Moscow presented a risk that technological secrets from F-35s in Turkey could make their way to Russia.

    The program’s international reach, meanwhile, is only becoming bigger. Ten international partners and customers have committed to buying the jet, and eight of them have received their first F-35s. Israel was the first country to use the fighter in combat, announcing in May 2018 that it had used the F-35 in two separate airstrikes on undisclosed targets in the Middle East.

    The cost of the plane continues to decrease as the growth in sales reduces the unit cost per jet, with the price of a conventional F-35A — the variant purchased by most international customers — falling to $89.2 million in 2018. Back in 2006, the first batch cost $241.2 million per plane. In June, Lockheed and the Pentagon announced a handshake deal that would see the price of the F-35A drop to the long-awaited level of $80 million, about equal to older planes like the F/A-18 Super Hornet. “This is going to be the first fighter jet produced in the thousands for a very long time,” said Richard Aboulafia, an aerospace analyst with the Teal Group. “None of this is stoppable. It will be remembered, as the smoke clears, as something that worked far better than critics thought it would, but something you’d never, ever want to do again.”

    Hill Air Force Base in Utah, home to the Air Force’s first operational F-35s, is tasked with preparing pilots for combat and has some of the highest availability rates among all installations that fly the aircraft — a key measure that the service uses to track the proportion of aircraft that are operational and ready to fly. But long turnaround times for some maintenance tasks has meant that about 30 percent of the squadron’s aircraft are grounded at any given time. At some bases that fly the older models, the availability rate is far lower: Sometimes more than 60 percent of their F-35s are not operable. In 2017 and 2018, only about half of the F-35 fleet was available to fly at a given time, with the rest down for maintenance.

    A major cause of F-35s sitting idle on the ground is a shortage of replacement parts. Lockheed and Defense Department officials have blamed each other for the problem, and there probably is plenty of fault to go around. The planes require a dizzying number of components sourced from different suppliers, and replacement parts are not getting to the flight line when they are needed. For instance, F-35s have encountered problems with the canopy, the glass enclosure that protects the cockpit, and jets can sometimes wait for a year to receive the necessary repair.

    Lockheed has begun fronting its own money to buy spare parts in advance, with the expectation that the Defense Department will repay the company later. It’s also trying to roll all of the F-35’s needs together, so that its suppliers can deliver parts for both new aircraft and old. Winter is skeptical that Lockheed’s actions will fix the problem. “Lockheed Martin’s assertion that this will all be done in two years or so was the same thing that was said two years ago,” he said. “It’s always two years to success, every time we talk.” But Lockheed is only partly responsible for the shortage of parts. An April 2019 investigation by the Government Accountability Office found that the Pentagon had a repair backlog of about 4,300 parts, wasn’t managing its inventory properly and often lacked data on the cost and current location of its F-35 components.

    Again, it’s a problem that could be compounded by the move to full-rate production. As Lockheed is responsible for building a much larger number of jets and prioritizes delivering those new aircraft to its customers, the F-35s already in operation will face even stiffer competition for spare parts.

    Slow and complicated maintenance is not a minor problem. As is generally the case for most weapons systems, maintenance is expected to make up more than 70 percent of the F-35 program’s total cost over the projected lifetime of the program. And managing these costs only grows more critical as more F-35s come online.

    An important measure of the cost, sustainability and value of the new jet is its total operating cost. In 2018, flying an F-35A cost about $44,000 per hour on average — about double the cost of operating the Navy’s Boeing F/A-18E/F Super Hornet. Some of the military’s top officials, including Gen. Dave Goldfein, the Air Force’s chief of staff, and former Air Force Secretary Heather Wilson, have complained that it is too expensive to fly and maintain the F-35, raising the possibility that the service may have to buy fewer of them if costs don’t shrink.

    In 2018, Goldfein called the F-35 “a computer that happens to fly” — a popular characterization among F-35 advocates, highlighting the plane’s ability to collect and analyze data in order to knock out enemy planes and missiles. But as China develops its own stealth fighters and pumps government money into research on supercomputing and artificial intelligence, the Pentagon is wondering how it can continue to give F-35 technology a competitive edge against America’s adversaries.

    One solution favored by Winter during his recent tenure was so-called agile software development. His vision for “continuous capability development and delivery” resembles DevOps, a popular method in the private sector for quickly testing and evaluating features for new products. Coders generate software upgrades or patches in a matter of days or weeks, pass them along to users to test and then push out the update more widely if the changes are successful. That speed would be a major improvement on the months, or in some cases a year or more, that it can take defense contractors to deliver a software patch right now.

    Winter also made it a priority to push for drastic streamlining in the process for testing new software in the F-35. Under the existing procedures, the Pentagon can require test flights for more than 300 different factors or functions when a new software load is installed. Winter worked to cut that down to a single validation flight, to test just the software and the systems it affects, rather than retesting the performance of the whole aircraft. A trial program staffed with a team of Air Force and Lockheed coders proved that the method works and doesn’t put pilots at risk, and Winter’s rapid software development strategy is now being implemented. But moving to an agile software approach for the F-35 presents a huge challenge for the sluggish and bureaucratic military acquisition system, and there’s no blueprint for how to integrate it alongside the traditional processes for developing and testing hardware.

    As with all stories involving the tangled web that is the Pentagon bureaucracy, it’s tempting to try to look for a hidden root behind all the problems — greedy corporate executives, corrupt generals, the military-industrial complex itself. But those closest to the F-35 program, the engineers, software developers and midlevel managers, express the same things over and over. Frustration that the tremendous scope of the program keeps them from being able to do more to fix it; and a wounded sense of pride for the impressive technological advances they have achieved, but that often seem lost in the intractable tangle of complications and setbacks.

    Over the next few months, the program will move through grueling evaluations overseen by the Pentagon’s independent weapons tester. These tests are meant to shake out any last bugs before full-rate production starts. In June, Winter said that none of the remaining problems are serious enough to delay full production. But even after the testing ends, there will inevitably be issues in need of fixes.

    In some ways, that’s a feature of today’s changing battlefield. There will always be new threats to face, new upgrades to develop, new technical problems to solve. Defense Department officials continue to assert that the adaptiveness of the F-35 makes it the best option to stand up to such uncertainties. Which is a good thing if true, given that it’s the only option. Because even if the F-35 doesn’t manage to become the unbeatable plane the Pentagon dreamed of, it has become the unkillable program.

      gunslinger πραγματικά νομίζεις ότι διαβάζει κανείς τα σεντόνια clopy paste που ανεβάζεις;

      είπαμε: έχεις πέσει έξω σε όλες τις προβλέψεις

      πες μας καλύτερα τι να παίξουμε στο στοίχημα και άσε τις αεροπορικές αναλύσεις

      έχεις βαλθεί να βγάλεις το Φ35 ελαττωματικό. Εσυ ξέρεις, η αμερικανική αεροπορία/ναυτικό/πεζοναύτες/δυτικές αεροπορίες δεν ξέρουν και απλά αποφάσισαν να πετάξουν 30 δις έτσι

      όπως σου είπα, πες μας εάν θα φέρει η αεκαρα διπλό και άσε τις αμυντικές αναλύσεις

        Προφανώς δεν έγινε έτσι απλά, αλλά αφού δεν διάβασες τα παραπάνω(επειδή σε ενοχλούν) γράφεις ότι να’ναι και το ρίχνεις στα αθλητικά πετάγοντας την μπάλα στην εξέδρα.

        Όσες φορές παραθέτω(οι και άλλοι σχολιαστές) αναφορές από ΗΠΑ που επισημάνουν σοβαρά προβλήματα στο πρόγραμμα, η όταν γράφω ο ίδιος για το θέμα, παρατηρώ ιδιαίτερη αναστάτωση και υστερικές αντιδράσεις από εσένα.

        Εάν ήταν όλα εντάξει στο θέμα(όπως υποστηρίζεις συνέχεια, δεν θα σε έπιανε υστερία με την παραμικρή αρνητική αναφορά για το συγκεκριμένο πρόγραμμα(ας μην το παραδέχεσαι ότι είσαι φανατικός fanboy που γουστάρει παραμύθι).

        Ιδέα μου είναι, η υπάρχει περίπτωση να σας έχουν στα κλουβιά και σας αμολάνε για κατήχηση, όταν ζορίζουν τα πράγματα στα επικοινωνιακά και δεν περνάει η γραμμή μάρκετινγκ της εταιρίας;

        “όταν ζορίζουν τα πράγματα στα επικοινωνιακά και δεν περνάει η γραμμή μάρκετινγκ της εταιρίας;”

        σε περίπτωση που δεν το παρατήρησες η αμερικανική κυβέρνηση αποφάσισε να δώσει 34 δις για το Φ35

        εάν αυτό εσυ το εκλαμβάνεις ως ζόρισμα τότε πες μας τι είναι επιτυχία για εσένα, ένα διαγαλαξιακό συμβόλαιο;

        τι θα κάνει η αεκαρα πες μου και άσε τα περί του Φ35
