In desicions such as this, i put a lot of faith in the opinions of the pilots who fly the state-of-the-art machines. It would appear that they think the F-22 is a worthy part of our defense system.
With the multitude of systems at hand, the F-22 is, IMHO, a step in the right direction, and a valuable addition to our arsenal.
I could accept that it could fill a needed slot that no one is allowing anything better to fill.
As I said above, fine--field a few wings of such.
But let us not pretend that it's the latest--even the latest already fielded.
