Vandenberg Air Force Base plans to test launch an unarmed Minuteman III intercontinental ballistic missile Wednesday morning.
The launch is scheduled for April 25 between 3:26 a.m. and 9:36 a.m.
The Air Force says the purpose of the launch is to test the system, procedures and Airmen involved in all phases of the program.
Air Force officials say there are usually four such tests per year. The last Minuteman III test launch occurred on Aug. 2, 2017. A launch that was scheduled for Feb. 2018 was postponed.
