ULA Vulcan-Centaur, USSF-106, August 12, 2025

As Space Coast skies faded into night, United Launch Alliance launched their Vulcan-Centaur rocket from Space Launch Complex-41 at 7:59 PM Eastern Time, carrying the classified USSF-106 mission for the U.S. Space Force. The evening launch, near the end of the one-hour window, was a successful return for the vehicle after its near-catastrophic solid rocket failure in its last launch in October, 2024.

This was Vulcan-Centaur’s first operational mission and the first national security payload to utilize its services, a milestone ULA has been working toward since 2014. ULA has faced scrutiny over Vulcan, with military officials calling for more reliability and accountability as the company shifts gears to its new fleet. There are no more Delta-family launches left, and a dwindling number of Atlas-V launches, most of which are planned for Amazon’s Kuiper Project as well as the Boeing Starliner program.
