I agree, it would be ALOT cheaper & more effective just to upgrade legacy aircraft. The U.S. Air Force now spends a little over $100 billion a year. Just about everything in the U.S. Air Force can maintain air superiority for at least 50 more years without the F35. A good sized fleet of F15's, F16's, F18's, & F22's are enough to go up against just about anything the U.S. Is usually threatened by. Plus if they had to they could re purpose/upgrade the YF23 to be a very capable 6th gen fighter to go up against 5th gen fighters that may be a threat to the U.S.
