Isn’t the corrosion due to some ‘green tech’ primer?
I’m not sure, but speaking as a former carrier sailor, I can tell you that saltwater corrosion is a constant menace and plays merry hob on just about any kind of sensitive electronic gear. It has to be fought constantly. Practically everything electronic built for shipboard duty has to be “hardened” against it.
I just shudder to think of what they would have to do to make the F-22 carrier compatible, but it wouldn’t be cheap.
