The Arnold Engineering Development Complex (AEDC), Arnold Engineering Development Center before July 2012, is an Air Force Material Command facility under the control of the Air Force Test Center (AFTC). Headquartered at Arnold Air Force Base, Tennessee, the Complex also operates from geographically separated units at Ames Research Center, Mountain View and Edwards AFB, California; Peterson AFB, Colorado; Eglin AFB, Florida; the Federal Research Center at White Oak, Maryland; Holloman AFB, Kirtland AFB, and White Sands Missile Range, New Mexico; Wright-Patterson AFB, Ohio, and Hill AFB, Utah. AEDC operates more than 68 test facilities, including, but not limited to, aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, environmental chambers, arc heaters, ballistic ranges, sled tracks, centrifuges, and other specialized test units.

AEDC conducts developmental testing and evaluation for the Nation through modeling, simulation, ground, and flight testing. Testing will evaluate aircraft, missile, and space systems/subsystems at the flight conditions they will experience during a mission. The complex aims to be the nation's best value ground test and analysis source for aerospace and defense systems.
