Arnold Engineering Development Complex

Arnold Engineering Development Complex is the largest complex of flight simulation test facilities in the nation. The complex was dedicated in June 1951 by President Harry Truman and named after five-star General of the Air Force Henry “Hap” Arnold, visionary leader of the Army Air Forces in World War II and the only airman to hold five-star rank. This complex has a replacement value of $11.8 billion for the 43 test cells presently located at Arnold Air Force Base, Tenn., and the complex’s two remote operating locations – the Hypervelocity Tunnel 9 in White Oak, Md., and the National Full-Scale Aerodynamics Complex located on NASA’s Ames Research Center at Moffett Field, Calif. The Tunnel 9 test facilities simulate flight from subsonic to hypersonic speeds at altitudes from sea level to space while NFAC provides a critical capability for aeronautics research, particularly rotorcraft research.
