Mission brief

What is happening

SpaceX is launching USSF-627 on a Falcon 9 Block 5 from Space Launch Complex 4E at Vandenberg SFB, CA, USA. It is a classified government mission heading to Low Earth Orbit. The first stage, B1103, is flying for the 7th time, and will attempt a droneship at sea.

Why it matters

Details of classified national security payloads are withheld, so the mission profile is usually only partly published and coverage often ends early.
