Two F-15E Strike Eagles maneuver to bomb a ground target during a training flight April 20 over Alaska. The F-15Es are assigned to the 90th Fighter Squadron at Elmendorf Air Force Base, Alaska, which traces its history back to August 1917. An array of avionics and electronics systems gives the F-15E the capability to fight at low altitude, day or night, and in all weather. The F-15E at Elmendorf AFB will soon be replaced by the F-22 Raptor. (U.S. Air Force photo/Tech. Sgt. Keith Brown)
