Official Description

The United States Space Force, through the Space Development Agency (SDA), is responsible for orchestrating the development and fielding of the Department of Defense’s Proliferated Warfighter Space Architecture (PWSA)—a resilient, threat-driven constellation of sensing and data transport satellites in Low Earth Orbit (LEO). Built on a spiral development model, PWSA is deployed in two-year tranches, requiring a flexible and adaptive approach to Test and Evaluation (T&E) that aligns with rapid acq...
