'LowObservable' also said: "...The Thermion coating reflects one of the two LH-related heating questions, which was the effect of F-35 exhaust on non-skid surfaces. The other was the long-term effect (if any) of heat and blast in terms of thermal/mechanical fatigue."
I had thought this THERMION topic was covered here already. I'll have to check. Anyway IF - as said by many by now - that the F-35B thermal/exhaust footprint is equivalent to the AV-8B then where is the problem? THERMION is a new non skid coating that is slated to be used by all USN flat decks eventually because of all things it is more hard wearing than the current non-skid. But hey the F-35B is going to melt all around it I know.
