The Tejon Ranch Radar Cross Section Facility was a radar cross-section (RCS) testing site operated by Northrop Corporation—later Northrop Grumman—from the 1980s to 2011 in Antelope Valley, California, United States. Located at the southern edge of the Tehachapi Mountains, it was one of the few private outdoor ranges in the country designed to help develop stealth technology for military aircraft, including the B-2 Spirit stealth bomber.

Northrop Grumman closed the site after plans were approved to build nearby photovoltaic power stations that were said to interfere with radar testing. https://en.wikipedia.org/wiki/Tejon_Ranch_Radar_Cross_Section_Facility Background Nicknamed "America's Aerospace Valley", the Antelope Valley in Southern California has long served as a hub for the development of advanced, and often classified, aerospace systems.
