U.S. Air Force Senior Airman Christopher Lewis, 1st Maintenance Group weapons standardization lead crew member, prepares an AIM-9X missile to be loaded onto an F-22 Raptor, at Joint Base Langley-Eustis, Va., April 19, 2017. Compared to the older AIM-9M, the AIM-9X maneuvers easier, picks up heat signatures better and is a safer weapon overall. (U.S. Air Force photo/Airman 1st Class Amanda Dole)
