1st Space Brigade

The 1st Space Brigade is a United States Army unit. Assigned to the United States Army Space and Missile Defense Command, it is responsible for providing space combat power support to Army units. Activated in 2005 as a TOE unit after being provisionally active since 2003, it is headquartered at Colorado Springs, Colorado.

The 1st Space Brigade (Provisional) was activated in May 2003, with the 1st Space Battalion, the 1st Satellite Control Battalion (later to become the 53rd Signal Battalion), and the 193rd Space Battalion (Colorado Army National Guard). On 20 October 2007 the provisional 193rd Space Battalion became a permanent-status unit, the 117th Space Battalion.

Since 2019, five missile defense batteries have been assigned to 1st Space Brigade including two in Japan and one each in Israel, Turkey, and Qatar.

The mission of 1st Space Brigade is to "conduct continuous, global space support, space control and space force enhancement operations in support of U.S. Strategic Command and Supported Combatant Commanders enabling the delivery of decisive combat power."

Structure
The brigade also has five missile defense batteries equipped with AN/TPY-2 forward-based radar conducting ballistic missile tracking operations in support of theater and homeland defense. The forward-based radar may also be used to conduct space surveillance and data collection. In 2023, the brigade also operated Site 512, a United States Department of Defence radar facility in Negev, Israel.

The 117th Space Battalion, Colorado Army National Guard has a training, readiness, and oversight (TRO) relationship with the 1st Space Brigade but is not actually part of it, as of 2021.
