Area 51 got its name from its location on a grid map. The U.S. Geological Survey designated the area as "Area 51" because it simply corresponds to its location on a grid in the Nevada Test and Training Range. It was not officially acknowledged until the CIA publicly acknowledged its existence in 2013.

They take their name from Area 51, a military base in the desert of southern Nevada.
No one revealed Area 51.
They have a few. One is near area 51 and another is between Phoneix and Tucson.
Since the government and military claim there is nothing there and nothing is being hidden I doubt they will tell us the real name. So for now it will have to be known as Area 51.
