An operational test launch of an unarmed Minuteman III intercontinental ballistic missile (ICBM) is scheduled to occur on May 21, 2025 from the North Vandenberg Space Force Base in California.
NORTH AMERICA — On May 21, 2025, an operational test launch of an unarmed Minuteman III intercontinental ballistic missile (ICBM) is scheduled to occur between 07:01 and 12:01 UTC from the North Vandenberg Space Force Base in California.
This test, overseen by the Air Force Global Strike Command (AFGSC), aims to demonstrate the readiness of U.S. nuclear forces and provide confidence in the lethality and effectiveness of the nation’s nuclear deterrent.
According to Space Launch Delta 30, the launch is routine, scheduled years in advance, and part of a series of over 300 similar tests conducted to validate the safety, security, and reliability of the ICBM system.
Historical Context
The Minuteman III ICBM, introduced in the 1970s, forms a key component of the U.S. nuclear triad, alongside submarine-launched ballistic missiles and strategic bombers. Regular testing ensures its continued effectiveness, addressing potential issues with the aging system and providing data for modernization efforts, such as the Sentinel program.
A previous test on February 19, 2025, at 09:00 UTC from Vandenberg Space Force Base saw the reentry vehicle travel approximately 4,200 miles (6,759 kilometers) to the Ronald Reagan Ballistic Missile Defense Test Site at Kwajalein Atoll.
These routine launches underscore the U.S. commitment to maintaining a credible nuclear deterrent amid evolving global threats.
