F-35 design problems: list of high priority modifications………..

Gepubliceerd door JSFNieuws.nl om 18:38 onder Aanschaf JSF, Ontwikkeling JSF

Do you want to know the plain truth about the F-35 Joint Strike Fighter?
Don’t you like believing F-35 crtitcal journalists?
Do you prefer optimistic US generals?
Or the industry public relations machine?
Or do you like the honey-sweet words of the politicians, with their own agenda?

Read from the REAL world, a summary of the inconvenient truth about the F35 Joint Strike Fighter design problems. An official US Department of Defense document (5 Mb download, see page 215-230) is telling you the real story in an overview of about 230 high-priority modifications………… How many pages is the list of low-priority (design) problems?
And what about Initial Operational Capability (IOC) in 2016? And the taxpayers in Australia, The Netherlands, Norway, Italy, UK, are they paying the modifications of their AirForces F-35s?

Planned Modification costs US Air Force onl during FY2014-Fy2019:
- Modification of in-service F-35A CTOL aircraft USAF: US$ 1.389.368 million (1.39 billion)
Total delivered F-35As USAF about 100 units, this means modification costs amount US$ 13 million/aircraft.

The list in the orginal US DOD document:


This effort (MN-F3516) funds retrofits due to concurrency changes to correct deficiencies discovered after DD-250 of the last aircraft in a given Low Rate Initial Production (LRIP) lot. This includes modifications required to extend aircraft service life currently limited by low-life parts, and relieve capability limitations driven by concurrency of production with development. The concurrency funding line will procure the highest priority modifications from the Tri-Service Modification Prioritization List, as soon as they become supportable from an engineering, production, and installation standpoint. The list is vetted by the Services and Partners every 6 months to ensure the list accurately reflects existing requirements as well as emerging issues. Per-kit costs will vary for each modification being implemented, and in some cases will also vary for aircraft from different LRIP lots to implement an individual modification. For FY16, the highest priority modifications will directly support USAF IOC, Block 3i, and tactics development. The following modifications will be the highest priorities for accomplishment throughout the F-35A CTOL fleet using funds from this Budget Activity.

One Response to “F-35 design problems: list of high priority modifications………..”

    1. Dit betreft een lijst met 230 high priority modifications. Low priority modifications zijn nog niet eens genoemd. En de JSF bevindt zich nog steeds in de SDD fase en wie weet hoeveel lijken er nog meer uit de kast komen naarmate de SDD fase vordert. Het was toch allemaal slechts afvinken van computer berekeningen en simulaties. Amehoela, maar dat weten we al vele jaren net zoals zoveel andere foute uitgangspunten en aannames.
    Nu is mijn technische kennis van statistiek en kansberekening op mijn leeftijd inmiddels tanende, maar als ik simpelweg uitga van 4 LRIP versies x 230 tekortkomingen dan kom je op zijn minst uit op 920 correctie mogelijkheden, maar het aantal combinaties is vele malen groter. Wie kan dat nog met pen en papier of desnoods computer bijhouden, want ALIS werkt nog voor geen meter en niemand heeft meer het overzicht.

    2. Kan/wil iemand mij uitleggen waarom onlangs onze 2 Klu testkisten van Eglin Florida zijn overgevlogen naar Edwards in Californiƫ? Ja, om deel te nemen aan de OT&E phase zo werd gezegd. Maar die fase is vooralsnog op zijn vroegst pas voorzien begin 2016 en met onze LRIP 2 en3 versie kun je nauwelijks iets meer testen dan na opstarten van A naar B te vliegen of een lokaal sightseeing tripje te maken. Of vaart de KLu in deze een eigen magic koers?
