A re-engined Super Hornet (like the F-14D) w/ more thrust & lower fuel burn could likely launch in basic engine w/out a/b and thereby gain about 15 minutes more combat radius - which would be huge. I assume the airframe design pretty much limits it to the 1.6 mach it already has.
All the AF's F-15's could all greatly benefit from the AESA radar already going into all the Super Hornets. A big question, to me, is how the AF justifies the 336 F-15C's it already has. They are single-mission a/c without a mission in Iraq & Afghanistan. If I were managing the AF, I'd shit-can them & load-up on all the F-15E's I could afford or buy all the Block 60 F-16's Congress would allow. The Israeli F-16I's are great examples of what you can do w/ the Falcon if you apply brains to the mission.
JMHO, of course.
Don't look now, but USAF introduced AESA first as a retrofit to the F-15C squadrons at Elmendorf along with AIM-9X/JHMCS and Link 16 (Nov 03 IOC).
