Falcon 9 SDA Tranche 1 Tracking Layer C

This is the first of five missions by the Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA). While the Transport Layer is the data backbone that ensures continuous tactical data relay, the Tracking Layer will provide global indications, warning, tracking, and targeting of advanced missile threats, including hypersonic missile systems.

A SpaceX Falcon 9 rocket will launch the SDA Tranche 1 Tracking Layer C mission in Q4 2026.
