The first in a series of new U.S. military satellites is now set for liftoff from the Central Coast.
SpaceX will launch the Space Development Agency's Tranche 1 mission from Vandenberg Space Force Base at 7:12 a.m. Wednesday. The Falcon 9 rocket will boost 21 small satellites into orbit.
They're expected to be part of a network of more than 150 satellites providing military tactical communications and early warnings about missiles being fired. Some test satellites have already been launched, but these are expected to be the first operational versions.
The reusable first stage booster is set to land on a barge off the West Coast.
