Duke Field — Crestview, United States

EGI is Duke Field, a U.S. Air Force auxiliary airfield located near Crestview, Florida, part of the larger Eglin Air Force Base complex. Duke Field supports Air Force Reserve units, including special operations and combat aviation training, taking advantage of the extensive restricted airspace and testing ranges associated with Eglin. The field has historically hosted various reserve wings conducting airlift and special mission training. Unlike the main Eglin runway, EGI functions as a satellite field handling specific training and support missions rather than the bulk of installation operations. It is not open to civilian air traffic. The base's presence reflects the broader concentration of military aviation infrastructure across the Florida Panhandle's Eglin reservation.
