The 10th Aerospace Defense Group was inactivated on 31 December 1970 by the United States Air Force (USAF). Its last assignment was with Fourteenth Aerospace Force at Vandenberg Air Force Base, California. The 10th Aerospace Defense Group and Squadron were the sole operators of the United States' second nuclear-tipped anti-satellite weapon, Weapons System 437 (WS-437). For this reason the squadron continues the group history through temporary bestowal.
