Desert Rock Airport — Mercury, United States

DRA identifies Desert Rock Airport, located near Mercury, Nevada, within the boundaries of the former Nevada Test Site, now known as the Nevada National Security Site. Historically, the airfield supported nuclear weapons testing operations conducted by the U.S. government during the Cold War era, ferrying personnel and equipment to the remote desert testing grounds. Today DRA continues to serve limited government and contractor operations related to the site's ongoing research and security functions rather than any form of public or commercial aviation. Access to the surrounding area remains restricted, and the airport's use reflects its unique history as infrastructure built for one of the most sensitive government programs in American history.
