> The F-22 isn't built anymore.

It could be, if necessary, spun back into production. It would be very expensive and take time, at least $50B to produce 200 more and a few years to get restarted, but it's not like it would need to be designed again. We know how to make them. The issue seems to be the concern that future threats will make F-22 a poor match, and that it will compete financially against new programs that may be a better match. But who really knows what the threat will be in 2035? Maybe the F-22 is just right, and if it is and we need more, we'll make more.
