An unarmed Minuteman III intercontinental ballistic missile (ICBM) accelerates toward a test range near Guam, March 27, 2015, after launching from Vandenberg Air Force Base, Calif. The ICBM was the second fired for testing and evaluation purposes in the course of a week, with both Malmstrom and F. E. Warren AFBs sending crews and randomly selected missiles to Vandenberg AFB.
