The F-15EX is now called Eagle II
The USAF plans to buy at least 144 F-15EXs to replace the F-15C/D fleet. Lt. Gen. Mike Loh, Air National Guard director, stated that either F-15EXs or F-35As would replace the F-15C/D fleet.
The F-15EX includes a series of upgrades compared to the older F-15C Eagle and F-15E Strike Eagle models, including the Eagle Passive/Active Warning and Survivability System electronic warfare system, a digital cockpit, the more advanced ADCP-II mission computer from Honeywell, and fly-by-wire flight controls.
The F-15EX made its first flight on February 2nd at Lambert International Airport in St. Louis, Missouri. On March 10th, Boeing delivered the first aircraft to the Air Force, which is currently putting the plane through operational tests at Eglin Air Base.
