ICBM test launch confirms system reliability

Vandenberg Space Force Base, Calif. — The Air Force launched an unarmed Minuteman III intercontinental ballistic missile just after midnight Monday, a routine test that service officials said was scheduled years in advance and not tied to current events.

Designated GT 256, the launch from Vandenberg Space Force Base at 12:01 a.m. Pacific Time served as a comprehensive operational check of both the aging missile system and the airmen who operate and maintain it, according to Air Force Global Strike Command.

“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 to assess propulsion, guidance and reentry performance under high stress, the command said.

“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.”

Data from end-to-end ICBM tests are shared across government agencies to inform sustainment and lifecycle decisions, the Air Force said. The release referenced the Department of Energy and U.S. Strategic Command among recipients, and also mentioned the “Department of War,” a term the U.S. government no longer uses.

“These operational tests are the most visible and vital way we verify the readiness of our systems,” said Col. Dustin Harmon, 377th Test and Evaluation Group commander. “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.”

Aircrews and maintainers conduct the event as a high-fidelity rehearsal of daily procedures, using it to validate training against real-world execution, the command said.

“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.”

The Minuteman III, first fielded in the 1970s, forms the land-based leg of the U.S. nuclear triad. The Air Force is developing its replacement, the LGM-35A Sentinel, and says ongoing tests will ensure the current missile force remains safe, secure and effective until the new system is fully deployed.
