Space Delta 3 (DEL 3) is a United States Space Force unit responsible for preparing forces for executing combat-ready space electromagnetic warfare operations to dominate the space domain. It is headquartered Peterson Space Force Base.[3][4][2][5]

Activated on 24 July 2020, it replaced the former 21st Space Wing's 721st Operations Group upon establishment.[6] The 721st Operations Group was activated on 10 October 2019 partly by realigning units from the former 21st Operations Group to focus securing the electromagnetic spectrum for national security space operations.[7]
