The U.S. Air Force Global Strike Command carried out a test launch of an unarmed Minuteman III intercontinental ballistic missile (ICBM) from Vandenberg Space Force Base, California, on 5 November 2025. The launch, designated GT 254, was conducted to evaluate the operational readiness, reliability and accuracy of the system.
The launch sequence was initiated by personnel from the 625th Strategic Operations Squadron using the Airborne Launch Control System aboard a U.S. Navy E-6B Mercury aircraft. The procedure demonstrated the system’s function as an alternative command and control method for the ICBM force.
“GT 254 is not just a launch – it is a comprehensive assessment to verify and validate the ICBM system’s ability to perform its critical mission,” said Lt. Col. Karrie Wray, commander of the 576th Flight Test Squadron. “The data collected during the test is invaluable in ensuring the continued reliability and accuracy of the ICBM weapon system.”
The operation was overseen by the 377th Test and Evaluation Group, which is responsible for all dedicated ICBM testing within the Air Force. Col. Dustin Harmon, who commands the group, stated that the activity confirmed the system’s functionality across different operational conditions. “This test validated the reliability, adaptability and modularity of the weapon system,” he said. “Through this comprehensive assessment, conducted by a dedicated team of AFGSC Airmen, we ensure the highest standards of integrity and reliability for the Nation’s ICBM system.”
The unarmed reentry vehicle traveled approximately 4,200 miles to the Ronald Reagan Ballistic Missile Defense Test Site at Kwajalein Atoll in the Republic of the Marshall Islands. Data from radars and optical tracking systems will be used in further analysis.
Personnel from all three missile wings under Air Force Global Strike Command took part in preparing and supporting the operation. The 90th Missile Wing at F.E. Warren Air Force Base provided maintenance support throughout the test cycle.
Gen. S.L. Davis, commander of Air Force Global Strike Command, noted that the test takes place as the Air Force transitions to the incoming Sentinel ICBM system. “As we modernize to the Sentinel weapon system, we must continue to maintain the readiness of the existing Minuteman III fleet. GT 254 helps fulfill that commitment, ensuring its continued accuracy and reliability,” he said.
