Probably a little late, and
Im not sure if anyone mentioned before, but keep in mind that over half of USAF 15E's have 220, not 229.
And ill tell you right now from a maintenance standpoint, the 229 sucks. Pilots love them, we hate them.
The Strike Eagle has the same wings as far as I know, I want to say that I put a C-Model wing on my jet a few years back after a pylon related incident.
The Landing gear and Cockpit/Avionics are two of the biggest differences. CFT's can be removed in a matter of minutes as long as they have no gas. 2 bolts, 8 cannon plugs and 3 panels. 2 bolts. pretty scarey
I cant speak as to how much the airframe is beefed up, that is more sheetmetal shop than crew chiefs, but excluding CFT hardpoints, all the other hardpoints are the same as light greys
