Launch context

Generated from source records

USSF-627: Falcon 9 Block 5, operated by SpaceX. Pad: Space Launch Complex 4E, Vandenberg SFB, CA, USA. Mission type: Government/Top Secret; target orbit: Low Earth Orbit. Window opens: Tue 10 Nov 2026, 03:03 UTC. Go confirms the listed plan, not liftoff. 2 schedule moves recorded; last detected 3 Nov 2026. Vehicle: 283/283 resolved orbital outcomes succeeded (100%) in our records since 4 Jan 2025. Pad: 132 orbital attempts in our records since 10 Jan 2025.

What these records cover

Partial coverage of stored records, not lifetime or worldwide totals. Counts use known orbital attempts with a source date at or before this snapshot and a status confirming liftoff or an outcome. Scheduled, upstream-missing, suborbital and unknown-orbit records are excluded. Source dates are NET estimates, not verified actual liftoff times.

The vehicle percentage is Success / (Success + Failure + Partial Failure). In Flight and Payload Deployed count as attempts but are excluded from that denominator. Figures describe the stored record at this snapshot, not the vehicle's flight number or a prediction of this launch's outcome.

Launch Library 2 record checked . Recorded timing does not establish actual liftoff; plans can change.
