Air Force Successfully Test Launches Minuteman III Armed with Multiple Reentry Vehicles

Key Takeaways

The Air Force’s Global Strike Command conducted an operational test launch of an unarmed Minuteman III missile with two test reentry vehicles.
The scheduled test, which took place at Vandenberg Space Force Base, was part of a long-term evaluation program to ensure missile reliability.
The Air Force is advancing the LGM-35A Sentinel program while also exploring ways to extend the Minuteman III’s service life to 2050.

Test Launch Details

The Air Force Global Strike Command (AFGSC) successfully conducted an operational test launch of an unarmed Minuteman III intercontinental ballistic missile (ICBM) on Tuesday at 11:01 p.m. PST. This launch, designated GT 255, was executed from Vandenberg Space Force Base in California and was planned years in advance, not as a reaction to recent global events.

The test involved two reentry vehicles designed to improve effectiveness against defended targets. These vehicles traveled thousands of miles, ultimately reaching a designated target at Kwajalein Atoll in the Marshall Islands.

Lt. Col. Karrie Wray, commander of the 576th Flight Test Squadron, highlighted the significance of the test, stating, “GT 255 allowed us to assess the performance of individual components of the missile system.” Continuing evaluations like this one contribute to enhancing the overall performance and readiness of the entire ICBM fleet, which is crucial for the land-based component of the nation’s nuclear triad.

Importance of Testing

Gen. S.L. Davis, the commander of AFGSC, emphasized the critical nature of such tests, mentioning, “It is essential to test all aspects of our ICBM force, including our ability to deliver multiple, independently targeted payloads with absolute precision.” The GT 255 test was instrumental in validating the synchronization of the weapon system, from launch to reentry vehicle deployment, ensuring precise execution.

During the launch, engineers and specialists from the 377th Test and Evaluation Group meticulously collected performance data regarding the missile’s accuracy and reliability. This information is shared with the Defense Department, the Department of Energy, and U.S. Strategic Command for force development evaluations. Col. Dustin Harmon, commander of the 377th Group, remarked that these test launches serve as vital verification methods for U.S. capabilities, confirming that the systems remain ready and reliable.

Support and Future Developments

The preparation for the launch required months of meticulous planning and coordination. Maintenance efforts were supported by personnel from the 91st Missile Wing at Minot Air Force Base in North Dakota, while operators from all three missile wings contributed to executing the launch.

Gen. Davis also noted the importance of the gathered data, emphasizing, “The data we gather ensures our long-range strike capabilities are not just theoretical, but a proven, reliable, and lethal force, ready to defend the nation at a moment’s notice.”

Looking ahead, the Air Force is advancing the LGM-35A Sentinel program as the next generation of land-based nuclear deterrents. Due to delays in this program, there are ongoing evaluations to ensure that the Minuteman III can remain operational through 2050, extending its service life by more than a decade beyond its intended timeline.
