SpaceX Falcon 9 launched the classified USSF-385 mission from Space Launch Complex 4E (SLC-4E), Vandenberg Space Force Base on Saturday (Sept. 26), at 1400 UTC, marking the sixth and final Falcon 9 launch from the West Coast base in September.
The first-stage booster, B1100 successfully landed on the autonomous droneship 'Of Course I Still Love You' in the Pacific Ocean about 8.5 minutes after liftoff as planned. B1100 completed its 10th flight, having previously launched the NROL-95 mission and eight Starlink missions. The Falcon 9 has now flown 108 times in 2026. The vast majority of these missions — 75% of them — Starlink broadband constellation, which currently consists of more than 11,000 satellites in low Earth orbit.
The payload details remain classified, and SpaceX terminated its live webcast shortly after the first-stage booster landed, omitting views of the upper-stage flight and payload deployment as requested by the military customer.
USSF-385 is understood to be the third in a series deploying satellites based on SpaceX’s Starshield, a government-focused variant of the Starlink constellation designed for resilient low-Earth-orbit communications and sensing which aims to provide the U.S. military with a proliferated fleet of hundreds of spacecraft, making the network too large for adversaries to blind with anti-satellite weapons.
The mission caps a rapid deployment pace, representing the fourth national security launch from SLC-4E in just 43 days. This follows USSF-366 (Aug. 15), USSF-153 (Sept 10), and USSF-259 (Sept 17).
Vandenberg has become SpaceX’s primary site for Falcon 9 flights as operations at Cape Canaveral shift toward Starship.
