The launch, originally scheduled for Tuesday, has been pushed back to Wednesday. The window opens at 4:06 p.m.
The launch is the second of 10 Tranche 1 missions. The mission sends satellites into low-Earth orbit to provide a global high-speed data network for military use.
The launch is set to liftoff from Vandenberg's Space Launch Complex 4 East.
The first-stage booster supporting the mission has been used six previous times. Following stage separation, it’s set to land on a droneship in the Pacific Ocean. No sonic boom is expected to be heard locally.
A live webcast on SpaceX’s X account and website will begin about 10 minutes before liftoff.
