There likely is something there, although it was pulled out and sent to Wyoming temporarily when Area 51 first got a lot of publicity in the late 80s
and early 90s.... But then the military (in violation of federal law) made the largest federal land grab in history, totally cutting Area 51 off from
outside observers, and they moved all the sensitive stuff back to it.
There are of course other similar facilities. The underground facility at Dulce is the main R&D facility, as well as Pine Gap in Australia. This is
another one about 100 miles from the HAARP installation in Alaska as well.
