The Department of War and U.S. Space Force conducted an operational test launch of an unarmed Minuteman III intercontinental ballistic missile from Vandenberg Space Force Base, California, in the early hours of November 5. The launch took place at 1:35 a.m. Pacific Time and was designated GT 254, according to the announcement. The Department of War said the test was carried out to evaluate the reliability, operational readiness, and accuracy of the Minuteman III system, which remains a central element of the United States’ nuclear deterrence structure. The unarmed missile’s reentry vehicle traveled approximately 4,200 miles to the U.S. Army Space and Missile Defense Command’s Ronald Reagan Ballistic Missile Defense Test Site at Kwajalein Atoll in the Republic of the Marshall Islands. The launch was initiated by Airmen from Air Force Global Strike Command’s 625th Strategic Operations Squadron using the Airborne Launch Control System from aboard a U.S. Navy E-6B Mercury aircraft. The use of the airborne system demonstrated the availability of a backup command and control capability for the ICBM force. “GT 254 is not just a launch – it's 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 Western Test Range at Vandenberg serves as the testing ground for launches of this type. The Department of War noted that these activities are carried out routinely and are not connected to any ongoing geopolitical events. The Reagan Test Site collected data using high-fidelity radar, optical sensors, and telemetry during the terminal phase of the flight. “This test validated the reliability, adaptability, and modularity of the weapon system,” said Col. Dustin Harmon, 377th Test and Evaluation Group commander. “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.” Personnel from all three missile wings under Air Force Global Strike Command took part, with maintenance support provided by the 90th Missile Wing at F.E. Warren Air Force Base in Wyoming. The 377th Test and Evaluation Group oversaw planning and execution. The Minuteman III, first fielded in the 1970s, is being maintained while the U.S. transitions to the new LGM-35A Sentinel ICBM. Until the Sentinel enters full operational service, continued validation tests ensure that the legacy system remains viable. "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,” said Gen. S.L. Davis, commander of Air Force Global Strike Command. The Department of War also stated publicly: “Under @POTUS & @SECWAR, we have PEACE THROUGH STRENGTH.”
