The '''Tonopah Test Range''' (TTR, also designated as '''Area 52''') is a highly classified, restricted military installation of the [[United States Department of Defense]], and [[United States Department of Energy]]  ([[Stockpile stewardship|nuclear stockpile stewardship]]) located about {{convert|30|mi|km}} southeast of [[Tonopah, Nevada]].  It is part of the northern fringe of the [[Nevada Test and Training Range|Nellis Range]], measuring {{convert|625|sqmi|abbr=on}}.  Tonopah Test Range is located about {{convert|70|mi|km}} northwest of [[Groom 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 generally 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.<ref name="sandia2003" />  The airspace comprises restricted area R-4809 of the [[Nevada Test and Training Range]] and is often used for military training.
