SpaceX to launch 21 satellites for US military's internet tomorrow
On October 15, 2025, SpaceX's Falcon 9 will blast off from California, carrying 21 satellites for the US Space Development Agency.
This launch is all about building a faster, more secure military communications network in low Earth orbit—think of it as giving the military's internet a major upgrade.
Lockheed Martin is building these satellites
This is the second batch for the Tranche 1 Transport Layer (T1TL), following another launch just last month.
Lockheed Martin built these satellites, joining earlier ones from York Space Systems; Northrop Grumman will also provide 42 satellites in future launches, for a total of 126 in this new constellation.
Watch the launch live online
The rocket booster (B1093) flying tonight has already been to space six times before—including five Starlink missions and the last T1TL launch.
After takeoff, it'll aim to land on SpaceX's drone ship "Of Course I Still Love You" out at sea (always fun to watch).
Details like satellite deployment timing are being kept under wraps by the Space Development Agency.
T1TL is part of a bigger project
T1TL is part of a bigger project called the Proliferated Warfighter Space Architecture—basically, seven layers of tech that get updated every two years to stay ahead.
If you're into space or tech, you can catch the whole thing live on SpaceX's site or X account and see how these launches are quietly shaping the future of global security.
