Tranche 1 Transport Layer E 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 York Space Systems.

The Falcon 9 1st stage carries 2 customer payload from Besxar Space Industries for testing their Fabships pilot reusable semiconductor wafers manufacturing pods in launch and re-entry environments.
Low Earth Orbit B1090 - Flight Proven ( ) A Shortfall of GravitasSXM-11 is the 12th high-powered, digital, audio radio satellite built by Lanteris Space (ex-Maxar, Space System/Loral) for SiriusXM. The SXM-11 satellite will be based on the proven IM-1300 (ex-LS-1300)-class platform and built at the company’s manufacturing facility in Palo Alto, California. SXM-11 has a large, mesh, unfurlable reflector almost 10 meters in diameter that allows SiriusXM programming to reach its radios, including those in moving vehicles.
