Isn’t that the one that we cant make more of w/o starting from scratch because Obama had the tooling/dies/blueprints etc. all destroyed?
The basic F-22 design is 1970s and 1980s technology and the YF-22 first flew in 1990.
So much has changed that it's better to start with a clean sheet design.
If fact, the biggest limitation of the F-35 and the one that designers are struggling with is that the current hardware and form factor of the F-35 airframe is having a hard time keeping up with the vision of what a 2040s F-35 objective system development path is going to look like.
The F-22 is a great airplane but is after it's current suite of upgrades it's likley end of it's cost effective retrofitable development potential.
