United States Space Command (aka: SPACECOM) is a unified combatant command of the Department of Defense, responsible for military operations in outer space.
The majority of forces for U.S. Space Command are organized, trained, equipped by the U.S. Space Force.
The Space Force’s service component to Space Command is Space Operations Command, providing the majority of space forces.
Recently, Red Stone Arsenal, Huntsville, Alabama, was selected to host SPACECOM headquarters.
The Department of the Air Force anticipates making a final decision for the location of U.S. Space Command Headquarters in Spring 2023, pending the results from the required environmental impact analysis.
Colorado Springs, Colorado, remains the provisional headquarters until the permanent location is ready to support the mission.
In November 2020, the service selected six candidate locations to host the military’s 11th unified combatant command. The bases included Redstone; Kirtland Air Force Base, New Mexico; Offutt Air Force Base, Nebraska; Patrick Air Force Base, Florida; Peterson Air Force Base, Colorado; and Port San Antonio at Kelly Field, Texas.
Redstone is the service’s preferred location. In a separate release, the Air Force said that the other locations remain reasonable alternatives until an environmental impact analysis on Redstone is complete. The final decision is expected in 2023, according to the release.
The location is expected to host roughly 1,400 personnel, spokeswoman Ann Stefanek said at the time.
SPACECOM was reactivated in August 2019, before the establishment of the Space Force, the military’s sixth branch, that December.
SPACECOM is responsible for military operations related to space, while the Space Force organizes and trains space personnel. Like the other military branches, the Space Force has its headquarters at the Pentagon.
The command is temporarily housed at Peterson AFB in Colorado Springs, which is also home to a robust, space-focused infrastructure with the nearby Schriever Air Force Base and Cheyenne Mountain Air Force Station. Colorado Springs will remain the “provisional location” until facilities at Redstone are ready, the Air Force said.
Costs for new construction to support SPACECOM are estimated at nearly $1 billion dollars.
Huntsville, Alabama is already home to the Missile Defense Agency, Army Space and Missile Command, Army Aviation and Missile Command, the Defense Intelligence Agency/Missile and Space Intelligence Center — has been adding even more military and federal entities.
