About this launch

OneWeb 21 is a launch of the Falcon 9 Block 5 rocket operated by SpaceX. No launch date has been set yet. Launch Library 2 currently lists it as no earlier than November 2026, so the date and time shown on this page are placeholders until a real date is announced. The launch site is Space Launch Complex 4E, Vandenberg SFB, CA, USA. The target orbit is Polar Orbit. Mission type: Communications. Launch Library 2 lists the current status as “To Be Determined”.

Mission description

A batch of 32 satellites for the OneWeb satellite constellation, which is intended to provide global Internet broadband service for individual consumers. The constellation is planned to have around 648 microsatellites (of which 60 are spares), around 150 kg each, operating in Ku-band from low Earth orbit.

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.

No per-launch YouTube stream is listed yet. Try the provider’s channel, which often carries the webcast when it starts:

What to expect from OneWeb 21

This mission, OneWeb 21, uses a Falcon 9 Block 5 operated by SpaceX and lifts off from Space Launch Complex 4E, Vandenberg SFB, CA, USA.

Communications missions usually deliver satellites for broadband, broadcast or relay services.

Target orbit: Polar Orbit. A polar orbit passes over or near both poles, so over time the spacecraft sees the whole surface of Earth.

Rocket and provider in our data

Falcon 9 Block 5 has 49 launches in T-ZERO’s data: 13 completed (all 13 successful), and 36 upcoming. 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

There is no firm date yet. The entry reads NET November 2026, where NET means “no earlier than”; until a day is announced, treat that as a rough target only. Its status is “TBD”: no launch date has been determined yet.
