Here's what we know about the Air Force's new F-15EX
US Air Force/Samuel King Jr A month after its first flight, the Air Force's first F-15EX arrived at Eglin Air Force Base, escorted by an F-15C and F-15E. The F-15EX is seen as a cost-effective and expedient solution to refresh the F‑15C/D fleet and to augment the F-15E fleet. The first F-15EX arrived at Eglin Air Force Base (Florida), escorted by its two older siblings, the F-15C Eagle and the F-15E Strike Eagle, on March 11, 2021, a day after the US Air Force officially accepted the aircraft at Boeing's St. Louis facility.
