It is my belief that we need to rely less on unreliable coatings for aircraft survivability and rely more on speed. The big down side for the defense contractors is in order to design aircraft that are fast once again, they would have to stop designing aircraft by committee and go back to using actual, identifiable and accountable aircraft designers. They won't do that because aircraft designers are too high profile, and thus are a threat to the nonsense system by which the government procures aircraft.

You have to look no further than Pierre Sprey to see that I'm right about this. Look at all the trouble the one remaining aircraft designer has given the military industrial complex over the years. Now imagine if there were people like him currently designing our aircraft. I can tell you for certain, they would not go along with these 20-30 year development cycles. That's nearly an entire career spent on one airplane!

Oh, I forgot to mention that the Raptors are rusting. The chemical mixtures aren't standing still as the various chemicals react with each other and moisture from the environment. They've replaced the stealthy "gap-filler" used in the F-22, because the old brand was eating into the frame. And the lack of drainage has caused the ejection seat rods to corrode.

So the problems could be caused by the unique chemical brew in each Raptor, or by some sort of mold that was carried from aircraft to aircraft on the boots of the ground crews.

The current thinking on the F-22 is that the problems may be caused by a combination of faults in the OBOGS, chemicals in the stealth coatings (that need to be reapplied frequently), chemicals used in the structure of the aircraft, and the way that the aircraft is flown (The pilots are subjected to sudden high-Gs while breathing high oxygen fractions at low pressure.)

The F-35 uses a slightly different environment system (with a brand new OBOGS setup), has the stealth baked in instead of slathered on, has a structure built of even more advanced materials than the F-22 (with unknown health hazards), and does not fly as high or fast as the F-22. (It flies a lot more like other jet fighters.)

So it is unlikely that the same mystery cause will afflict the F-35, but things that were safe before have had additional variables applied to them.
