Maybe this is not military thinking, but what happen to the old saying if it’s not broken don’t fix it. I’m all for the latest and greatest if it’s needed, but who are we trying to stay a head of? The Russians can’t pay its pilots let alone put new aircraft in the air, China can’t fart without the US intelligence services knowing about it. By and far the US is a head of the game not only with aircraft in service but pilots as well. Do we need this aircraft? Can we live without it? We did not have this aircraft in Desert Strom and the Iraqi AF was bomb back to the Stone Age, I know this only set them back about three weeks and loss’s hit the allied side as well but the loss’s where due to blindly fired AAA, that’s what cause the shooting down of the F117 years ago. Sounds to me like we are putting all our eggs in one basket.
