Rocket Launch: Falcon 9 Block 5 — SDA Tranche 1 Transport Layer F

Tranche 1 Transport Layer F 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. Launching from Space Launch Complex 4E, Vandenberg SFB, CA, USA. Launch times shift often — check back for updates. Visible from much of Lompoc; popular viewing spots include Ocean Ave west of town and Surf Beach (when open).
