US launches unarmed ballistic missile from Vandenberg Space Force Base

"The Minuteman III, or LGM-30G, was first deployed in 1970 and is scheduled to be phased out by 2030 and replaced with the upcoming LGM-35A Sentinel ICBM(opens in new tab) currently under development."

An important note near the end of the report. 1970 shows the missile tested is now some 52 years old.
