SpaceX Falcon 9 Successfully Launches USSF-153

A Falcon 9 rocket thundered off the California coast Thursday morning as SpaceX successfully carried out the USSF-153 mission for the United States Space Force, lifting off from Space Launch Complex 4E at Vandenberg Space Force Base on the Central Coast.

The launch took place no earlier than 8:42 AM Pacific time on September 10, 2026, with the available window stretching through 11:37 AM. The mission marked another classified chapter in the growing partnership between SpaceX and the Space Force, with the Falcon 9 Block 5 vehicle delivering its payload to low Earth orbit.

Details surrounding the USSF-153 payload remain classified, as is typical with Space Force missions of this nature. However, analysts have noted intriguing clues in the mission profile. The drop zones designated for the rocket's stages align precisely with those used during previous Starlink Group 15 launches, leading observers to speculate that the payload could be a batch of classified satellites built on SpaceX's Starshield satellite bus. Starshield is a government-focused derivative of SpaceX's commercial Starlink technology, designed to meet the demanding requirements of national security space operations. While SpaceX and the Space Force have not confirmed the nature of the payload, the orbital parameters and stage recovery corridors have fueled well-informed speculation within the spaceflight community.

The Falcon 9 performed as expected throughout the flight, and the classified payload was successfully delivered to low Earth orbit. Vandenberg Space Force Base, perched along the rugged coastline of California's Central Coast, once again served as the backdrop for a mission quietly advancing the nation's presence in space. The base has become one of the most active launch sites in the country, handling a steady cadence of both commercial and national security missions throughout the year.
