Lisätään listaan vielä koneen max 7G kyky, rakenteellinen ylipaino ja erityisesti rungon ongelmat.Huomautettakoon, että en vaadi varauksettomasti B-mallin hankintaa, mutta en näe siinä mitään valtavia teknisiä heikkouksia verrattuna A-malliin..
"The JPO suspended durability testing for the F-35B after completion of the second lifetime of testing in February 2017; the test article had so many repairs it was no longer representative of the production aircraft. The program has not yet procured another durability test article for the F-35B to begin the third lifetime of testing. The effect of the failures observed and repairs required during the first two lifetimes of testing on the service life certification of the F-35B aircraft is still to be determined. The service life for all three variants is planned to be 8,000 hours, however the F-35B service life may be less than that, even with extensive modifications to strengthen the aircraft already produced.
