Bomber and fighter aircraft training wrapping up in Utah
Munitions sit on the aircraft ramp at Hill Air Force Base, Utah, May 3, 2016, waiting to be loaded onto F-15 Strike Eagle aircraft from Seymour Johnson AFB, N.C. The F-15s, along with other fighter and bomber aircraft, participated in the U.S. Air Force air-to-ground weapons evaluation known as Combat Hammer. Combat Hammer, which runs until May 14, tests and validates the performance of crews, pilots and their technology while deploying precision-guided munitions. (U.S. Air Force photo by R. Nial Bradshaw)
