Falcon 9 Block 5 | SDA Tranche 1 Transport Layer D — visibility, launch time & where to look
Tranche 1 Transport Layer D is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites. The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance.

Where to look
A rocket lifts off below the horizon for distant viewers, then climbs into view as it gains altitude and flies downrange. Closer to the pad you'll see it within seconds; a few hundred miles away it can take three to six minutes to rise over the horizon. Find an open view in the direction shown for your city and start watching at liftoff.
Before you go
- Launch times change — scrubs and delays are common. Re-check the day of.
- Clear skies matter. Low cloud near the pad or along the trajectory can hide the rocket.
- Twilight launches are the most dramatic; daytime launches are the hardest to see at distance.
- Trajectory and timing here are estimates from a representative ascent profile.
