AFGSC Confirms Minuteman III ICBM Reliability with Successful Test Launch

On November 5, 2025, the Air Force Global Strike Command (AFGSC) successfully launched an unarmed Minuteman III intercontinental ballistic missile (ICBM) from Vandenberg Space Force Base in California. This pivotal test, known as GT 254, aimed to assess the reliability, operational readiness, and accuracy of the Minuteman III system, which is essential for national defense.

Details of the Test Launch

The launch was executed by a dedicated team from the 625th Strategic Operations Squadron using the Airborne Launch Control System (ALCS) from a U.S. Navy E-6B Mercury aircraft. This process aimed to validate the ALCS’s effectiveness as a backup command system within the ICBM force. Lt. Col. Karrie Wray, commander of the 576th Flight Test Squadron, remarked that the test was crucial for verifying the system’s mission performance.

Significance of the Launch

Validated reliability and adaptability of the Minuteman III system.
Provided invaluable data for consistent operational performance.
Conducted under stringent safety protocols to ensure safety and integrity.

Col. Dustin Harmon, commander of the 377th Test and Evaluation Group, emphasized the importance of maintaining high standards of reliability for the ICBM system. The 377th Test and Evaluation Group is the sole organization in the Air Force dedicated to ICBM tests, managing the meticulous planning and execution of test launches.

Data Collection and Analysis

Following the launch, the missile’s reentry vehicle traveled approximately 4,200 miles to the Ronald Reagan Ballistic Missile Defense Test Site located at the Kwajalein Atoll, Republic of the Marshall Islands. Advanced sensors at the site, including radars and telemetry, collected essential performance data during the flight’s terminal phase. This data is crucial for the ongoing research, development, and evaluation of U.S. defense systems.

Collaborative Efforts

The test launch involved Airmen from all three AFGSC missile wings, alongside maintainers from the 90th Missile Wing stationed at F.E. Warren Air Force Base in Wyoming. This teamwork highlighted the dedication and expertise necessary to operate and maintain the critical Minuteman III weapon system.

Future of the Minuteman III

As the U.S. Air Force transitions to the LGM-35A Sentinel weapon system, ensuring the readiness of the existing Minuteman III fleet is paramount. Gen. S.L. Davis, AFGSC commander, reiterated the importance of maintaining this fleet’s reliability, emphasizing that the GT 254 test was essential in fulfilling this commitment.
