A Minuteman III missile launched Tuesday night from Vandenberg Air Force Base.
Air Force Global Strike Command tells KSBY the unarmed intercontinental ballistic missile lifted off at 11:01 p.m., which was the start of the six-hour launch window.
A base spokesperson says these test launches provide instrumental data for future projects.
The base says the tests, which occur about four times a year, are not related to any real-world events.
