How to watch

When Launch Library 2 lists an official YouTube webcast, T-ZERO embeds it here (click play to load the YouTube player). We do not host video ourselves; the stream stays on YouTube. Launch times often move, so reload this page for the latest schedule. External links below if the player fails.

What to expect from USSF-627

USSF-627 is planned for a Falcon 9 Block 5, flown by SpaceX from Space Launch Complex 4E, Vandenberg SFB, CA, USA.

Launch Library 2 files this under Government/Top Secret, so payload details are often limited and public information can stay thin until after liftoff.

Target orbit: Low Earth Orbit. Low Earth Orbit (LEO) is the region up to roughly 2,000 km above Earth, where crewed spacecraft and many satellites operate.

Rocket and provider in our data

T-ZERO currently lists 49 launches of the Falcon 9 Block 5: 13 completed (all 13 successful); 36 upcoming. This is the 2nd of 4 upcoming Falcon 9 Block 5 launches that have a confirmed date. SpaceX has 54 launches across 3 rockets in our data, about 39% of the 140 launches we list. Space Launch Complex 4E is listed for 34 other launches in our data. T-ZERO keeps roughly the last two months of launches plus everything scheduled ahead, so these figures describe recent activity and are not an all-time record.

Timing

Treat the time above as a target, not a promise: NET means “no earlier than”, and slips of minutes, hours or whole days happen. Launch Library 2 lists a window of 4 hours, 03:03 UTC – 07:03 UTC. The status “Go” means Launch Library 2 treats the current launch time as confirmed by an official or reliable source; it can still slip.
