2/28/2012 - Barksdale Air Force Base, La. -- The launch of an unarmed operational test Minuteman III intercontinental ballistic missile at Vandenberg AFB, Calif. , has been postponed.
The test launch is delayed in order to replace a test-unique tracking component used only on test missiles. The test-unique tracking component monitors missile location within geographic boundaries of the test range.
This tracking system is used solely in test launches of Minuteman III missiles and does not affect the operational reliability, accuracy or performance of the system.
The launch has not yet been rescheduled.
