Tonopah Test Range Tonopah Test Range (TTR), is a restricted military installation located about 30 mi southeast of Tonopah, Nevada. It is part of the northern fringe of the Nellis Range, measuring 625 sqmi . Tonopah Test Range is located about 70 mi northwest of Groom Dry Lake, the home of the Area 51 facility. Like the Groom Lake facility, Tonopah is a site of interest to conspiracy theorists, mostly for its use of experimental and classified aircraft. As such, it is not the focus of alien enthusiasts, unlike its neighbor. It is currently used for nuclear weapons stockpile reliability testing, research and development of fusing and firing systems, and testing nuclear weapon delivery systems. The airspace comprises restricted area R-4809 of the Nevada Test and Training Range and is often used for military training.
