An unarmed Minuteman III intercontinental ballistic missile accelerates toward a test range near Guam March 27 after launching from Vandenberg Air Force Base. The ICBM was the second fired for testing and evaluation purposes in the course of a week, with both Malmstrom and F.E. Warren Air Force Base sending crews and randomly selected missiles to Vandenberg AFB to launch the missiles in conjunction with the 30th Space Wing and 576th Flight Test Squadron, which oversee the launch facilities and operational tests, respectively.
