Arnold Air Force Base (ICAO: KAYX, FAA LID: AYX) is a United States Air Force base located in Coffee and Franklin counties, Tennessee, adjacent to the city of Tullahoma. It is named for General Henry "Hap" Arnold, the father of the U.S. Air Force.

There is no longer an active airfield on the base, as the airfield was decommissioned in 2009. Army aviation assets (helicopters) continue to utilize Arnold as part of missions supporting Fort Campbell, Kentucky or the Tennessee Army National Guard.

The base is home to the Arnold Engineering Development Complex (AEDC), the most advanced and largest complex of flight simulation test facilities in the world. The center operates 58 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges and other specialized units. AEDC is an Air Force Test Center organization.

The commander of Arnold Engineering Development Center is Rodney F. Todaro. Mark A. Mehalic is the Executive Director, and Edward M. "Ed" Kraft is the chief technologist.

Camp Forrest, located in Tullahoma, Tennessee, was constructed as one of the Army’s largest training bases during the World War II period between 1941 and 1946. The camp, named after American Civil War cavalryman General Nathan Bedford Forrest, was originally named Camp Peay. Camp Peay was named after 1920’s Tennessee Governor Austin Peay and built east of Tullahoma, Tenn. as a National Guard Camp in 1926. Camp Peay covered 1,040 acres (4.2 km²). Camp Forrest covered 85,000 acres (340 km²) located just beyond the old Camp Peay.
