Space Development Agency

The Space Development Agency (SDA) is a United States Space Forcedirect-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.

The Space Development Agency's network of military satellites is called the Proliferated Warfighter Space Architecture. It is highlighted by White House executive order as a key element of the future Golden Dome (missile defense system).
