I think he was referring to restarting the F-22 production line.
I heard that was near impossible, because the tooling was destroyed.
The tooling exists and was carefully packed away. The problem is the stuff that wasn't F-22 specific, and we can't make anymore, because the company that makes them doesn't anymore. Or doesn't even exist.
It's old enough the mid-life upgrade (MLU) program is happening for it.
