Launch Successful

Tranche 1 Transport Layer A 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. This launch carries 21 satellites manufactured by Northrop Grumman.

Official outcome: Launch successful

Our final pre-flight call was GO at 85% confidence, T-2d 0h - and it was right.

✓ Call matched the outcome

Scoring rule: a launch that reached flight means the countdown proceeded, so a GO or HOLDING call is right and a SCRUB call is a false alarm. Only the last call made before T-0 counts.
