A team of Air Force Global Strike Command Airmen from the 90th Missile Wing at F.E. Warren Air Force Base, Wyo., launched an unarmed Minuteman III intercontinental ballistic missile equipped with a test reentry vehicle from Vandenberg Air Force Base, Calif., Oct. 21, 2015. The ICBM's reentry vehicle, which contained a telemetry package used for operational testing, traveled approximately 4,200 miles to the Kwajalein Atoll in the Marshall Islands. Test launches verify the accuracy and reliability of the ICBM weapon system, providing valuable data to ensure a continued safe, secure and effective nuclear deterrent.
