About this moment

Falcon 9 Block 5: SDA Tranche 1 Transport Layer D is expected Q4 2026. The exact day has not been announced yet.

SpaceX is preparing to launch SDA Tranche 1 Transport Layer D on a Falcon 9 Block 5 from Vandenberg SFB, CA, USA. 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. Launch is expected in Q4 2026 and no firm date has been announced yet.

The source has announced a date range. An exact day has not been confirmed.
