Replacing Strike Eagles with F-15EX is an option for USAF
The U.S. Air Force may replace its 218 F-15Es with F-15EXs, which could expand the new program to over 400 aircraft, according to service documents justifying the sole-source contract to Boeing.

In its F-15EX Justification and Approval (J&A) document, which was dated March 2018 but only published this month, the flying branch said while the F-15EX acquisition program is “initially” intended to refresh the aging F-15C/D, a decision to similarly replace the F-15E Strike Eagle fleet with the EX “has not been made, but remains an option.”
The documents also disclosed that Boeing will most likely build 144 F-15EX fighters to replace the 234 F-15C/Ds that are currently in USAF service. It also quoted the F-15 system program office as saying the EX will enjoy “90-95 percent commonality” with the F-15QA that Qatar has ordered. Deliveries of the F-15QA will commence soon.
It further justified the purchase by stating that it takes approximately “six months or less to transition from the F-15C/D to the F-15EX.” And transitioning from “F-15s to the F-35 (or any other airframe) will take approximately 18 months for an Active-duty squadron and 36 months for an Air National Guard squadron.”
