Or maybe
Boeing-Saab T7-A Redhawks? Do a deal with Saab to build them here instead of Gripens and get our full F-35 order?
Same advanced jet trainer as the USAF. Boeing aims to sell over 2,700 Redhawks globally so should be enough orders to keep the line going. Uses the same GE F404 engine as our Hornets so less training delta for our techs.
They are also looking at an F-7 armed version which could be used to supplement the F-35's in a Hi-Lo missile/drone defence mix:
