TECHNICAL DEFINITION

The Proliferated Warfighter Space Architecture (PWSA) is a U.S. Space Force and Space Development Agency (SDA) initiative deploying a resilient, distributed constellation of interconnected satellites in low-Earth orbit (LEO). This architecture provides global persistent missile tracking, tactical data links, and other critical warfighter capabilities, enhancing survivability against counter-space threats through proliferation and distribution.

BACKGROUND

The Space Development Agency (SDA) is a United States Space Force direct-reporting unit tasked with deploying disruptive space technology. One of the technologies being worked on is space-based missile tracking using large global satellite constellations made up of industry-procured low-cost satellites. The SDA has been managed by the United States Space Force since October 2022. By February 2024 the SDA had 38 satellites on orbit. SDA intends to have at least 1,000 satellites in low Earth orbit by 2026.
