Vandenberg Air Force Base plans to launch an unarmed Minuteman III Intercontinental ballistic missile in the early morning hours Wednesday.
The launch window is open from 12:01 a.m. to 6:01 a.m. Wednesday.
Air Force Global Strike Command says the launch is a test to determine the weapon system's effectiveness, readiness, and accuracy.
The most recent Minuteman III launch from Vandenberg Air Force Base was in the beginning of September.
