SpaceX has conducted several classified U.S. Space Force missions from Vandenberg Space Force Base in September and October 2026. On September 9, SpaceX scheduled the USSF-153 mission using a Falcon 9 rocket. The mission involved a classified payload, and the company planned to end its live webcast after the first-stage booster landing to protect sensitive information. The booster, B1081, was slated to land on the droneship ‘Of Course I Still Love You’. On September 25, SpaceX successfully launched the USSF-385 mission from Space Launch Complex 4E. As with previous national security deployments, SpaceX terminated its public webcast shortly after the first-stage booster, B1100, landed on the droneship ‘Of Course I Still Love You’ in the Pacific Ocean. This mission marked the third national security launch conducted by the company from Vandenberg in a 16-day period, following the USSF-153 and USSF-259 missions. Details regarding the USSF-385 payload, its destination, and its intended activities remain classified. On October 4, SpaceX scheduled the Tranche 1 Transport Layer A (T1TL-A) mission to launch 21 data transport satellites for the U.S. Space Force’s Space Development Agency (SDA). Departing from Space Launch Complex 4 East at Vandenberg, these These satellites are part of the Proliferated Warfighter Space Architecture (PWSA), a distributed constellation designed for orbital observation, missile tracking, and secure communications. The mission is part of the National Security Space Launch (NSSL) Phase 2 contract, with the first-stage booster, B1103, expected to land at Landing Zone 4. On October 5, SpaceX scrubbed After the T1TL-A mission after was scrubbed on October 5 when the countdown was halted at approximately T−58 seconds. seconds, SpaceX successfully launched the 21 Northrop Grumman-built satellites on October 10. This mission is successful launch delivered the fourth orbital plane for the transport layer. The T1TL satellites are designed to provide resilient, high-volume, and low-latency tactical communications, including Link 16 data links. The SDA expects the initial warfighting capabilities of nine planned the Tranche 1 launches intended constellation to build a distributed network of spacecraft. SpaceX is currently targeting a rescheduled launch for October 8 or 9. be realized in 2027.
