Makes sense it applies to all types, although you could make a case the F-22 is special given is high supercruise capabilities. There has to be some operational limit, and it's likely ram coatings dictate max speed. I certainly don't get the feeling it's the engines. Either RAM coatings or the canopy, take your pick. Maybe both..
Whatever the limits are, they're far higher vs. any 4th or 4++ whatever jet. Only the PAK FA and J-20 may be in the same ballpark, but not until such time as a suitable engine gets them there. From what it sounds like, that's going to be 5-10 years, at least. And you can bet F-22 upgrades will keep it ahead of the game. One of those might be better/higher speed threshold RAM (aren't we already hearing about that?) or a new canopy - if the latter is a limiting factor...
