What is the SDA Tranche 1 Transport Layer A mission?

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.

How is this verdict calculated?

The launch starts at 100 points and loses points for sustained wind, gusts, cloud cover, chance of precipitation and thunderstorm energy at Vandenberg SFB, CA, USA at the launch hour. 75–100 is GO, 50–74 is CAUTION, below 50 is NO-GO. This is an independent, indicative assessment, not the provider's official launch commit criteria.
