SpaceX successfully launched the USSF-385 mission on September 26, 2026, from Vandenberg Space Force Base in California. The classified payload was developed for the United States Space Force as part of ongoing national security space operations. While mission specifics remain restricted, analysts suggest the mission likely deployed a batch of classified low Earth orbit satellites based on SpaceX's Starshield satellite bus, a hardened variant designed for government applications. This assessment is supported by rocket stage drop zone locations matching those from previous Starlink deployment missions.

The Falcon 9 Block 5 launch vehicle lifted off from Space Launch Complex 4 East at 14:00 UTC on Saturday morning Pacific time. Vandenberg Space Force Base, located on California's central coast, serves as SpaceX's primary launch facility for polar and sun-synchronous orbit missions. The Block 5 variant represents the current production standard for Falcon 9, featuring enhanced reliability, reusability, and performance improvements over earlier iterations.

The launch proceeded without incident, successfully placing its classified payload into orbit. The mission represents continued expansion of the Space Force's military satellite constellation and demonstrates SpaceX's role as the primary launch provider for classified national security missions. Booster recovery operations were conducted following standard procedures, supporting SpaceX's reusability objectives.
