You'll find out as soon as American bombers start getting shot from the sky by enemy 5th Generation fighter planes.The U.S. has had Air Superiority because we paid for it in cold hard cash.
Air Superiority is not Guaranteed to U.S. I would Rather pay for it in cash than in the blood of our Air or Ground Forces who come under attack from those enemy Air Craft once they win Air Superiority.
Decades, not 'soon'.
Meanwhile first enlistment Americans will die for not having more basic weapons tailored to the war we have been fighting and will fight. The MRAPs for example. Having the Army use helicopters for CAS when safer fixed wings could take some burdens. We have and already pay in blood.
Regarding our bombers getting shot down by 5th generation enemy fighter planes, is the major threat to our bombers the fighter planes or is it missles launched either from the ground or other planes, and if from other planes I’m picturing the planes being sufficiently far away from the bombers that dogfighting abilities aren’t important.
Stealthiness may be the only advantage of a “new generation” fighter over older ones, and maybe that’s an extremely important advantage. Perhaps it is because a lot of our new military flying machines are stealthy. But improved missle guidance systems and unmanned aircraft seem like the big game changers.
