Watch live coverage as SpaceX launches a Falcon 9 rocket from California carrying a classified payload for the U.S. Space Force. Liftoff from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base is scheduled for Thursday, Sept. 10, during a launch window that opens at 8:37 a.m. PDT (11:37 a.m. EDT / 1537 UTC).

The first-stage booster, serial number B1081, launching for a 27th time, will land on the drone ship 'Of Course I Still Love You' nearly 8.5 minutes into the flight.

The USSF-153 mission will take a south-easterly trajectory upon departure from Vandenberg. 

Live commentary from Spaceflight Now's Will Robinson-Smith will be provided starting about 30 minutes prior to launch.

Tranche 1 Transport Layer A is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites.

The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance.

This launch carries 21 satellites manufactured by Northrop Grumman.
