2026-186 Falcon 9 Block 5 (USSF-366, R-1)
Vandenberg Space Force Base | 2026 Aug 16, 01:50 UTC | USA 620 (Starshield 0204) 2026-186A 100333 |
in space
|
One of a cluster of twenty three US government satellites carried on this launch, reportedly forming a communications network to support the remote sensing satellites in the Starshield constellation. Design is related the Starlink satellites. Released from launch vehicle about 60 minutes after lift off. The orbit listed is based on limited data released by Space-Track on August 28 but precise orbit is classified 'secret'.
All satellites were injected into similar orbits. |

2026-214 Falcon 9 Block 5 (USSF 259, TH-1)
Vandenberg Space Force Base | 2026 Sep 17, 01:07 UTC | |
in space
|
One of a cluster of seventeen US government satellites carried on this launch. Probably part of the government/military multi-purpose "Proliferated Warfighter Space Architecture" constellation. These satellites may be tasked with tracking objects flying within the Earth's atmosphere. Design is probably related to the Starlink satellites. Released from launch vehicle about 60 minutes after lift off. Orbit is based on limited information released by Space-Track.
All satellites were injected into similar orbits. |
