Air Force Global Strike Command conducted a test launch of an unarmed Minuteman III intercontinental ballistic missile from Vandenberg Space Force Base, California, on May 20 at 12:01 a.m. Pacific Time. The launch, designated GT 256, was a routine test scheduled years in advance and was not conducted in response to world events.

The Air Force said the launch served as a comprehensive operational test of both the Minuteman III weapon system and the personnel responsible for maintaining it. The event took place in a highly controlled testing environment intended to assess operational readiness across the ICBM enterprise.

“Our ability to conduct these rigorous, realistic tests is foundational to our national security,” said Gen. S.L. Davis, commander of Air Force Global Strike Command. “This launch verifies the health and readiness of our ICBM force, confirming the capability of every component of the ICBM enterprise, from our operators to the weapon system itself, to execute the mission.”

Engineers tracked the missile’s flight path to evaluate propulsion, guidance and reentry system performance under extreme physical stress. The Air Force said the data supports a full assessment of the missile’s end-to-end operational profile.

 

 

“This launch allows us to authenticate the complete performance profile of the Minuteman III,” said Lt. Col. Karrie Wray, commander of the 576th Flight Test Squadron. “It confirms the precision of the system, ensuring the reentry vehicle can be delivered to its target with pinpoint accuracy.”

The test also provided data to government agencies responsible for sustainment, engineering and lifecycle analysis. The information is distributed to the Department of War, the Department of Energy and U.S. Strategic Command.

“These operational tests are the most visible and vital way we verify the readiness of our systems,” said Col. Dustin Harmon, commander of the 377th Test and Evaluation Group. “More importantly, they are a direct reflection of the unmatched skill and dedication of the Airmen in our missile community who ensure this critical mission is a success every single day.”

Maintenance and operations crews supported the launch as a high-fidelity rehearsal of daily procedures. The Air Force said the test allowed crews to validate training against operational execution.

 

 

“A test launch is the culmination of immense preparation,” Davis said. “The dedication of every Airman here is clear, and their actions contribute directly to our current and future warfighting capability. We have been and will continue to be ‘Always Ready.”

As the Air Force prepares to transition to the LGM-35A Sentinel, the service said continued operational testing helps ensure the land-based leg of the nuclear triad remains safe, reliable and effective. The Minuteman III will remain in service until its successor is fully deployed.
