Airman Chris Hilton, left front, and Airman 1st Class Dominik Roeglin, right front, 362nd Training Squadron F-15 crew chief apprentice course students, open an F-15's nose at Sheppard Air Force Base, Texas, August 1, 2018. The radar used in the F-15 Fighting Falcon's at Sheppard are an A model. Older versions that are static, non-moving pieces. There are still some F-15s in service that use these A model radars, but everything is slowly progressing towards the fancier radars. (U.S. Air Force photo by Airman 1st Class Pedro Tenorio)
