The Space Development Agency (SDA) is a directorate of the United States Department of Defense's office of the under secretary of defense for research and engineering (OUSD (R&E)) which supports space development in the interests of U.S. national security. By design, the functions for acquisition and sustainment (A&S) are the responsibility of another under secretary of defense; this separation of function decouples the technology development of a working prototype system, even the systems as complicated as those taken on by the SDA, from overcomplication induced by the processes of the DoD.
The SDA was created in 2019 to implement the National Defense Space Architecture (NDSA). The SDA plans to transfer to the United States Space Force around October 2022, although details are still uncertain.
The satellite constellations are in near-polarlow earth orbit. Hundreds of satellites are expected by the end of the 2020s. "Would you be able to take out some of these satellites? Probably. Would you be able to take out all of these satellites? Probably not, before you are going to have a really bad day."—Derek Tournear: min -2:10 before the end of the video clip
