(KEYT) – An unarmed, intercontinental ballistic missile test is scheduled from Vandenberg SFB between 12:01 a.m. and 6:01 a.m. Pacific Time on Wednesday, May 20. The routine test, designated GT 256, of the Minuteman III is to ensure its operational availability and was scheduled years in advance shared Air Force Global Strike Command in a press release. The Minuteman III intercontinental ballistic missile (ICBM) weapon system has been in service in the United State's nuclear arsenal since the late 1970s and is one of hundreds of Minuteman III missiles that make up the nation's ground-based nuclear deterrence infrastructure as part of a trio of launch platforms that, "underwrites every U.S. military operation on the globe—it is the backstop and foundation of our national defense and that of our allies," detailed the U.S. Air Force's Nuclear Weapons Center.
