The main problem with the F-22 is that restarting production will cost $10 billion all on its own. Then each jet would be $200 million. [1] The F-15 is still produced in various configurations for our allies so any change/upgrade is going to be much cheaper.

F-22 is the greatest plane in the US arsenal. It's unhackable (because the IBM mainframe powering it is so old, it would be difficult for the chinese or russians to attempt to do so). And -nothing- can currently beat it in a 1v1.

The issue, however, is we can barely keep 50% of the already existing raptors operational. https://www.thedrive.com/the-war-zone/28659/air-force-admits...

The raptor is, unfortunately, not the future due to costs and maintenance (tho the f-35 is having the same maintenance issues with the stealth coating. Hopefully it's not as bad.)
