The Space Development Agency (SDA) is a United States Space Force direct-reporting unit tasked with deploying disruptive space technology. A primary focus is space-based missile defense 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. The agency was established by Mike Griffin in 2019 with his appointment to Under Secretary of Defense (R&E) by President Donald Trump. Griffin had long advocated for low Earth orbit constellations to eliminate U.S. vulnerability to ballistic missiles with his work on space-based interceptors for the Strategic Defense Initiative and Brilliant Pebbles in the 1980s. However these programs dissolved in the 1990s due to excess cost and political disagreement. Later, the United States and other countries developed hypersonic weapons, which Griffin argued were thermally dimmer and could only be reliably tracked by low-flying satellites with infrared sensors, creating a need to resurrect such programs. In addition to hypersonic weapons, the memorandum establishing the SDA also calls for a new space architecture "not bound by legacy methods or culture" that provides unifying command and control through a cross-domain artificial intelligence-enabled network.
