The next space launch, retrieved from our Launch Library 2 API, is Falcon 9 Block 5 | SDA Tranche 1 Transport Layer E. It is scheduled to be launched by SpaceX from Space Launch Complex 4E, Vandenberg SFB, CA, USA at 2026-07-16 20:22:00 UTC. Until then, this pad will have been used for 282 out of 898 launches from this location. The launch status is currently Go 🟩 . The mission type is Government/Top Secret and the payload will be injected into a Polar Orbit (PO).

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.
