An F-16 Fighting Falcon from the 422nd Test and Evaluation Squadron, Nellis Air Force Base, Nev., maneuvers into position to refuel off the tail of a KC-135 Stratotanker assigned to the 344th Air Refueling Squadron, McConnell Air Force Base, Kan., during a Red Flag 15-3 training sortie over the Nevada Test and Training Range, July 24, 2015. Aerial refueling extends an aircraft’s mission longevity, allowing strike packages to reach great distances in pursuing targets and enabling them to stay in the fight when needed.
