SpaceX Launches Tranche 0 Satellites for Space Development Agency.

The Space Development Agency (SDA) has successfully launched the first 10 satellites of Tranche 0 (T0) of the Proliferated Warfighter Space Architecture (PWSA) from Vandenberg Space Force Base, California. The T0 constellation will demonstrate low-latency communication links to support the warfighter with a resilient network of integrated capabilities, including tracking of advanced missile threats, from low-Earth orbit. Once completed, Tranche 0 will include 20 optically-connected data transport satellites and eight optically-connected missile warning/missile tracking satellites equipped with wide-field-of-view sensors.
