EGLIN AIR FORCE BASE, Fla. - A new F-15EX on March 11 flew from Boeing’s facility in St. Louis to Eglin Air Force Base alongside two older models, the F-15C jet fighter that it will replace, and F-15E jet fighter-bomber. The new warplane will join a testing and evaluation squadron at Eglin. Eglin is home to the 53rd and 96th Test Wings, both of which already operate the F-15 series of fighters. The two wings will complete the F-15EX’s developmental and operational testing simultaneously. The first F-15EX, known as EX1, will go to the 96th Test Wing’s 40th Flight Test Fighter Squadron. The second F-15EX, EX2, will go to the 53rd Wing’s 85th Test and Evaluation Squadron. (Source: Military and Aerospace Electronics, 03/31/21) Previous
