(UsualDosage) "Area 51" is a nickname for a military base located in Nevada. Situated at its center, near Groom Lake, is a large military airfield and one of the most secretive places in the world. The base's primary purpose is to support development and testing of experimental aircraft and weapons systems.
Other names used for the facility include "Dreamland," "Paradise Ranch," "Home Base," "Watertown Strip," "Groom Lake," and most recently "Homey Airport." The area is part of the Nellis Military Operations Area, and military pilots refer to the forbidden airspace around it (R-4808N) as The Box. The intense secrecy surrounding the base, the very existence of which the U.S. government barely acknowledges, has led it to become the frequent subject of conspiracy theories and UFO folklore.
