The U.S. Space Development Agency (SDA) is a U.S. Space Force direct-reporting unit focused on the rapid deployment of space-based capabilities to the joint warfighter. It aims to achieve this through the development, fielding, and operation of the Proliferated Warfighter Space Architecture, a threat-driven constellation of small satellites in low Earth orbit. SDA's key focus areas include military data and communications connectivity, missile tracking, and development of a resilient space architecture, working with partners like Lockheed Martin, SpaceX, and York Space Systems. Their work supports terrestrial missions and enhances warfighter lethality, maneuverability, and survivability.
