The satellites are expected to be deployed into low Earth orbit about an hour after liftoff.
The Falcon 9's first stage was previously launched on an Iridium mission last October and was recovered.
The payload is the fifth set of 10 new satellites launched for Iridium, which is replacing its entire global satellite network.
