The Purpose of the EX is to get foreign export dollars.
We are just buying some to replace old F-15C’s that break in half, so we don’t waste F22 hours intercepting Bear Bombers.
The power behind Biden will use the Military to control US citizens , Fighter Jets will not be needed
F-15 carries substantially more weapons payload than the F-35 and plays a differet role so comparing one against the other is unrealistic since they will be working in tandem. F-35 is the unseen quarterback directing F-15’s to targets after stealth wild weasel take out Sams. BTW, the F-15 is still one of the fastest fighters in the world. Yes, metal fatigue of the airframes/wings will be an issue but they will be x-rayed before being refitted. I see this as a stop gap measure until F-35 directed drones become available.
You see how many missiles they can put on that thing! Something like 22~24. An F22 using its sensors can data link targeting data to those Eagles.
The airframe,tools and maintenance processes for it are well known. New avionics suite is all the pilots will really need to come up to speed on.
