I also wonder about the strategic implications of this kind of complexity. If you lose an F-22, how many months does it take to make a new one? This isn't like WWII where new planes were rolling off a converted automobile assembly line every hour. If it takes many months to build one, could America ever find itself in a situation where it has more planes in the factories than it has in the fight? Surely someone in the Pentagon has considered this. I just wonder what the plan is.
