    Has the OBOGS on the navy F-18 and trainer been resolved by now?

    It seems to be a recurring issue.. F-22 and now F-35..

    The F-22 issue was a valve on the vest and not the OBOGS unit itself. No on the USN OBOGS issue, they are still having problems.

    This just in:

    The hypoxia incident appears to be isolated to Luke AFB and will not affect the F-35A’s appearance at the Paris air show, Lockheed spokesman says. The aircraft pair for the show will fly from Hill AFB, Utah and their test pilots have not experienced issues, says Lockheed.

    Air Force will likely lift F-35A grounding at Luke AFB on Saturday


    he Air Force has temporarily canceled flight operations at Luke Air Force Base, AZ, after five incidents of pilots experiencing "hypoxia-like symptoms." (UPDATED)

    "According to base officials, since May 2, five F-35A pilots assigned to Luke Air Force Base have reported physiological incidents while flying," the service said in a June 9 statement. "In each case, the aircraft's backup oxygen system operated as designed and the pilot followed the correct procedures, landing the aircraft safely."

    The grounding is currently limited to Luke AFB, and Air Force spokesman Mark Graff confirmed June 9 to Inside Defense the jets will likely begin flying again June 10.

    "This temporary cancellation is limited to today," Graff said.

    Graff said because the five incidents have only occurred with pilots from one base over a short period, the service has not put any limitations on flying operations, to include envelope restrictions, at any other locations.

    "Flying operations continue as normal for other F-35As and F-35 bases," Graff said.

    The service also did not confirm whether the issue impacts the B and C models, operated by the Marine Corps and Navy. The F-35 joint program office has established a formal action team of engineers, maintainers and aeromedical specialists to investigate the issue and will share the information with international partners, the release states.

    A Lockheed Martin spokesman said the company "stands ready to help in any way possible to address this issue," but deferred further comment to the Air Force. F-35 joint program office spokesman Joe DellaVedova said the enterprise takes a "comprehensive approach" to tracking reports of physiological issues and is working jointly with a number of F-35 stakeholders to understand the cause of the incidents at Luke AFB.

    Pilots experience symptoms of hypoxia when they have less oxygen than typically needed at certain altitudes. The Air Force had widespread incidents of hypoxia on the F-22 and, more recently, the Navy has grounded its T-45C training squadrons due to reports of "physiological events."

    Brig. Gen. Brook Leonard, commander of the grounded 56th Fighter Wing at Luke AFB, said the wing is "taking the necessary steps to find the root cause of these incidents."

    "Wing officials will educate U.S. and international pilots today on the situation and increase their awareness of hypoxia symptoms," according to the Air Force statement. "Pilots will also be briefed on all the incidents that have occurred and the successful actions taken by the pilots to safely recover their aircraft."

    Air Force Chief of Staff Gen. David Goldfein said during a June 6 hearing, before the grounding was announced, the service is working with the Navy as it addresses hypoxia issues and is "just beginning to look at the F-35 through the same lens."

    Would hypoxia effects be worse for pilots flying with an F-35 type helmet than it would with a conventional type helmet?

    Block 4 Follow On Modernization FY18 funding request totals $799 Million [ US Services $587 Million, International Program Partners - $212 Million].
    This builds upon the roughly $260 Million requested by the DOD for block 4 in FY16 and 17.

    About hypoxia, for once, i'll not jump on it. Every aircraft has its youth problem. As far as it is (really) fixed for FRP...

    [QUOTE]This is what happened in the Netherlands and I am pretty sure they will do the same in Belgium.
    If Belgium has the same ambition (and why not) F-35 will come out on top of that, even if it means you can only have 30 or so[QUOTE]

    Wow cheaper than Rafale F3R (not to talk about F4)

    Many aircraft continue to face issues and groundings even after they have achieved FOC, and are decades into service. We have fresh examples of that. Anyhow, not all problems are neccesarily with a system and not all system problems are necessarily design problems. Wait and see where this goes. Too early at the moment to draw a conclusion or figure out the root cause.

    This is an aviation forum, not some stupid political board. Trump mentioned a couple of the Pentagon's largest procurement programs in an address to the Coast Guard... big deal.

    Orbital ATK's ER solution features a number of design changes to the existing AARGM configuration and leverages what Mike Stuart, Orbital ATK's director of missiles strategy, business development and marketing, characterises as "higher technical readiness level (TRL) subcomponents with reduced risk, to accelerate the timeline to the US Navy customer".

    "From our design concept perspective, we took a look at the threats, we took a look at, most importantly, the ranges that we thought were going to be needed, and then we wanted to bring in technology associated with achieving those goals, that were higher TRL," Stuart told Jane's .

    The Orbital ATK design introduces an aft actuator control system with the mid-body wings on the legacy AARGM removed. This not only enables a form fit capability internal to the F-35 but also improves manoeuvrability and reduces drag, Stuart said. The company has introduced side-body strakes that deliver lift during the missile's flight.

    To assist the required range increment, the existing mid-body control section componentry is repackaged to deliver additional space for propulsion, while the airframe is tapered up from aft of the seeker section to deliver an approximate 10% increase in diameter, with consequent additional volume for propulsion.

    Stuart said the company is evaluating multiple sources for the aft actuator solution and also for the new rocket motor design that, Jane's understands, is expected to deliver an engagement speed that is double that of the current AARGM. "Our assessment is that there are propulsion options out there that are high TRL and can quickly transition into a production scenario to meet the USN's timelines," he said.

    While the propulsion type has yet to be decided, a ramjet solution has not been discounted. "The current Orbital ATK design concept is not a ramjet, but it certainly doesn't remove that potential. However, it will be the USN and its requirements office that make the final decision on where they want to go with propulsion," he said.


    'Increased Survivability' is built into the AARGM ER requirement, although Stuart declined to comment on the specifics of the Orbital ATK solution, noting only that "speed is in the equation. We're going double the range in about the same amount of time, and you have to increase speed to achieve that; so speed in and of itself is an improvement to survivability. There are other aspects of our design solution that improve survivability, but these are not releasable".

    I would like to buy that cameraman a lens cloth.

    Also... a nice performance. Paris is in for a treat.

    UPDATES
    WASHINGTON — F-35 flight operations at Luke Air Force Base, Arizona, will continue to be suspended as analysts investigate five incidents where pilots suffered hypoxia-like symptoms, a spokeswoman for the base said Monday.

    Since May 2, five 56th Fighter Wing pilots have reported symptoms of oxygen deprivation while flying the U.S. Air Force version of the joint strike fighter, including two incidents that occurred last week. In all cases, the backup oxygen systems kicked in and pilots were able to safely land the plane, but training has ground to a halt to allow a team from the F-35 Joint Program Office, or JPO, to study the events.

    Maj. Rebecca Heyse, spokeswoman for the 56th Fighter Wing, said a JPO team of engineers, maintainers and aeromedical specialists arrived on base Sunday and are currently narrowing down potential causes for the incidents. The hope is to identify the root cause over the next couple days, but no date has been set as this time for a tentative resumption of operations, she told Defense News.

    "The 56th Fighter Wing will continue their pause in local F-35A flying to coordinate analysis and communication between pilots, maintainers, medical professionals and a team of military and industry experts,” she said in a statement. “This coordination will include technical analysis of the physiological incidents to date and discussions on possible risk mitigation options to enable a return to flying operations.

    “Updates will be provided as our teams work together toward safely returning to building the future of airpower through trained F-35A pilots. The safety of our airmen is paramount and we will take as much time as necessary to ensure their safety."

    In the meantime, Heyse said the 56th Fighter Wing is continuing a variety of pilot education measures, including an all-call meeting with the JPO team to discuss the events. Cancellation of flight operations affects 49 pilots and 55 aircraft total.

    At this point, little is known about the incidents themselves, including whether the On-Board Oxygen Generating System failed in any of the cases. All five events occurred with different jets from multiple squadrons and production batches, Heyse confirmed. However, because only pilots from Luke AFB have developed hypoxia-like symptoms, the service continues to believe it remains a localized problem.

    Brig. Gen. Brook Leonard, commander of the 56th Fighter Wing, will make the final call on when to resume flight operations.

    Pentagon sends Congress legislative proposals; seeks new F-35 authority


    The Pentagon has submitted a package of legislative proposals to Congress, one of which seeks authority to enter into one or more economic order quantity contracts in fiscal year 2018 for the F-35 Joint Strike Fighter.

    The EOQ authority would apply to F-35 material and equipment for use in procurement contracts to be awarded between FY-19 and FY-20 and may not exceed $661 million.

    The request for EOQ authority is not unexpected as the Defense Department telegraphed this move when it awarded $1.37 billion to contractor Lockheed Martin on April 28 for F-35 long-lead materials to support a block buy for foreign military sales customers and international partner aircraft. At the time, a spokesman told Inside the Air Force it was the first contracting action to support a block buy and EOQ strategy.

    As previously reported by ITAF, the funds are slated to be used for low-rate initial production lots 12, 13 and 14, though the EOQ authority would have to be granted separately for each lot.

    Lt. Gen. Christopher Bogdan, the former F-35 program executive officer, told the House Armed Services tactical air and land subcommittee in February the block buy EOQ strategy would cover as many as 445 jets in lots 12, 13 and 14.

    Though the U.S. military plans to forgo a block-buy agreement for those lots, international partners and FMS customers will benefit from the agreement, he said.

    The United States will instead participate in a separate EOQ contract for each lot with an expected savings of approximately $2 billion.

    How on earth is it possible to publish something like this in June 2017!?

    Even reprinted in Scientific American: https://www.scientificamerican.com/a...trike-fighter/


    Incredible!

    It is easy to write trash if all you want to do is stir outrage and generate clicks. From the author's profile:

    Dr. Michael P. Hughes joined the Francis Marion faculty in 2003. He teaches corporate finance, financial markets, real estate finance, and investments. His research is focused in the areas of market microstructure, financial markets, fixed income securities, government and defense finance, options and derivatives, investments, international finance, central banking, and financial econometrics. Dr. Hughes' research has appeared in the Journal of Economics and Business, Quarterly Review of Economics and Finance, Journal of Economics and Finance, International Advances in Economic Research, Journal of Business Case Studies, Journal of Case Research in Business and Economics, and Journal of Business Cases and Applications, and Strategic Management Cases.

    Prior to his joining the ranks of academia, Dr. Hughes served over 21-years in the U.S. Air Force. During that time he spent over 14-years in nuclear treaty monitoring and related activities, while the initial 7-years were in the aircraft maintenance and engineering (propulsion) arena with F-4 and F-15 aircraft.
    So basically his qualifications are that roughly 30 years ago he performed maintenance on fighter engines.

    I was visiting a customer in Gonesse yesterday and I saw parts of the F35 demo.

    I thought the US were invading again but I realized it was the salon du Bourget.

    A read an article recently that described that the F-35 project is a failure!! I have briefed the article here - What Happened to F-35 Project from Lockheed Martin?
    Um why don't you actually read up on the program before trying to write about it? I stopped reading after this passage:

    With nearly US$ 1.5 trillion already spent, it has gone on to become one of the most expensive defense program in the world before it is phased out in 2070.
    Obviously someone who has no clue what's going on with the F-35 program and just reading clickbait.

    Nothing, as I have not seen it it in first person and have not the technical competence nor the experience to judge it from a simple video.

    Wait till the actual flight display? I don't expect anything to wow the average forum airshow pundits. Other than, it's there, it's actually a fighter, and there will more than a few twits with stopwatches trying to infer turn rate via demonstration.

    Sans, sarcasm. Having watched a few of the practice runs, the F-35 impresses in pitch rate so far, have not seen full roll rate. Never been a fan of the low speed maneuvering in air shows common now. The ripping past the crowd an pulling vertical was more exciting in person back in the day.
