What a joke you have a very good oneI got the answers. J-20 can spank USAF like flies. ;enjoy:
Yes there are report that's USAF already test flying 6th gen jetAre u sure?
This just a report not 100% accurate may be it will retire or may be not ? who knowsBut we don't retired J-20? Your logic failed...
B-52 and A-10 are exceptions to the trend. Most of A-10 peers have been long retiredIt's still a hard maybe on retirement. The US has historically had a hard time retiring even vintage aircrafts. Take the A-10 for example, they've been trying to retire that aircraft for literally decades, but have no far failed to do so. Same with the F-16 and F-15.
