Steven F. Udvar-Hazy Center

The Steven F. Udvar-Hazy Center is an annex of the Smithsonian Institution's National Air and Space Museum located at Dulles International Airport in Chantilly, Virginia, which houses much of the museum's collection of aircraft, spacecraft, and rockets, which are too large to be displayed at the main facility on the National Mall. The large hangar contains some of the most iconic artifacts in aviation history, including the Space Shuttle Discovery, the Enola Gay, and the Boeing 367-80, as well as examples of the SR-71 Blackbird and Concorde.
