United States Space Command (USSPACECOM orSPACECOM) is aunified combatant command of theUnited States Department of Defense, responsible for military operations inouter space, specifically all operations 100 kilometers (62 miles) and greater above meansea level. U.S. Space Command is responsible for the operational employment of space forces that are provided by the uniformed services of theDepartment of Defense.[6]
Space Command was originally created in September 1985 to provide joint command and control for all military forces in outer space and coordinate with the other combatant commands. SPACECOM was disestablished in 2002, and its responsibilities and forces were merged intoUnited States Strategic Command.[7] It was reestablished on 29 August 2019, with a reemphasized focus on space as a warfighting domain.
TheU.S. Space Force is the military service responsible for organizing, training, and equipping the majority of forces for U.S. Space Command, which also includes a smaller number of forces from each of the other branches of theU.S. Armed Forces.
U.S. Space Command, working with allies and partners, plans, executes, and integrates military spacepower into multi-domain global operations in order to deter aggression, defend national interests, and when necessary, defeat threats.[8]
U.S. Space Command has four "space truths" that provide the foundation for its vision and operations:[9]
Early military space activities were predominantly focused on research and development, rather than operations, and split across the Air Force, Army, and Navy. In 1959, AdmiralArleigh Burke proposed the creation of the Defense Astronautical Agency to control all military space programs. This proposal was supported by the Army and Navy, but opposed by the Air Force.[10]
Arguing that space defense was an extension of air defense, the Joint Chiefs of Staff ultimately agreed with the Air Force, putting operational control of space defense forces under the unifiedContinental Air Defense Command and multinationalNorth American Air Defense Command in 1960. In 1975, Continental Air Defense Command was inactivated and replaced withAerospace Defense Command (ADCOM), a specified command led by the Air Force. In 1981, North American Air Defense Command changed its name to North American Aerospace Defense Command to better reflect its role in both air and space defense.[10]

The Reagan Administration'sStrategic Defense Initiative brought a new focus on space. In 1983, GeneralJames V. Hartinger, the commander ofAerospace Defense Command andAir Force Space Command, proposed movement towards a unified space command. The Air Force supported a unified command, which would be dominated by the aerospace service, however, the Army, Navy, and Marine Corps were satisfied with the current arrangement. However, the White House supported the Air Force's position that a unified command should be created, and on 20 November 1984, PresidentRonald Reagan approved its establishment. U.S. Space Command's missions would include integrating tactical warning and space operations, including control of space, direction of space support activities, and planning for ballistic missile defense. U.S. Space Command would also replace Aerospace Defense Command as the supporting U.S. command to North American Aerospace Defense Command, sharing the same commander.[12]
On 23 September 1985, U.S. Space Command was activated as a functional combatant command atPeterson Air Force Base, Colorado Springs and Aerospace Defense Command was inactivated on 19 December 1986. In February 1988, U.S. Space Command was assigned the ballistic missile defense mission in preparation for assuming operational command of the Strategic Defense Initiative. However, the end of the Cold War significantly reduced the investment in SDI.[12]
In 1991, the Joint Chiefs of Staff debated establishing U.S. Strategic Command assume responsibility for nuclear deterrence, missile defense, and space. U.S. Space Command would have been made a sub-unified command under the U.S. Strategic Command. However, the decisive role played by U.S. Space Command in thePersian Gulf War prevented its absorption into U.S. Strategic Command, providing tactical missile warning, GPS, and other space data to forces in theater.[12]
In 1997, GeneralHowell M. Estes III proposed designating space as a geographic area of responsibility, transitioning U.S. Space Command from a functional to a geographic command. This effort was opposed by theJoint Staff, theState Department, and theNational Security Council and did not occur. However, there was growing discussion about giving U.S. Space Command the mission for information support and renaming it to United States Space and Information Command. While U.S. Space Command was not renamed, it did assume responsibility for information, or cyberspace, operations.[12]
Following theSeptember 11 attacks, there was a growing focus on homeland defense and counter-terrorism at the expense of space. The Defense Department was intent on establishingUnited States Northern Command, merging U.S. Space Command and U.S. Strategic Command in 2002. On 1 October 2002, the first U.S. Space Command was shut down.[13]
On 1 October 2002, as U.S. Space Command inactivated, a newU.S. Strategic Command atOffutt Air Force Base, Nebraska, stood up. Within STRATCOM, the responsibilities for space operations were initially managed by theJoint Functional Component Command for Space and Global Strike, led by the commander of the Air Force'sEighth Air Force.[14] However, in 2006, space regained its own functional component under U.S. Strategic Command, under the command of theFourteenth Air Force commanded.[13]
Following the inactivation of U.S. Space Command in 2002, Russia and China began developing sophisticated on-orbit capabilities and an array of counter-space weapons. In particular, China conducted the2007 Chinese anti-satellite missile test, destroying itsFengyun spacecraft, which, according toNASA, created 2,841 high-velocity debris items, a larger amount of dangerousspace junk than any other space event in history.[15][16] In 2008, U.S. Strategic Command conductedOperation Burnt Frost to destroy a non-functioningNational Reconnaissance Office satellite, before its toxic hydrazine tank could reenter and cause potential harm to human safety, with aRIM-161 Standard Missile 3 launched from theUSS Lake Erie.[17][18]
This construct lasted until 2017, when the commander of Air Force Space Command became the Joint Force Space Component Commander, replacing it.[13]

The2019 National Defense Authorization Act, which was signed into law in 2018, directed the re-establishment[19] of U.S. Space Command as a sub-unified combatant command underU.S. Strategic Command; however, in December 2018, theTrump administration directed that U.S. Space Command instead be a newly established, full unified combatant command, with full responsibilities for space.[20][21]
On 26 March 2019,U.S. Air Force GeneralJohn Raymond[22] was nominated to be the commander of the second establishment of USSPACECOM, pendingSenate approval.[19][23] In 2019 theDepartment of the Air Force released the list of finalists for the location of Headquarters Space Command:Cheyenne Mountain Air Force Station,Schriever Air Force Base,Peterson Air Force Base,Buckley Air Force Base,Vandenberg Air Force Base, andRedstone Arsenal.[24] U.S. Space Command was officially reestablished as a geographic combatant command on 29 August 2019, during a ceremony at theWhite House.[25][26] The formerJoint Force Space Component Commander was dissolved and folded into Space Command. Following the creation of theUnited States Space Force in December 2019, theDepartment of the Air Force widened its search for a location of Space Command's permanent headquarters.[27]

USSPACECOM has two subordinate commands: Combined Force Space Component Command (CFSCC), and Joint Task Force Space Defense (JTF-SD).[28] CFSCC plans, integrates, conducts, and assesses global space operations in order to deliver combat relevant space capabilities to Combatant Commanders, Coalition partners, the Joint Force, and the Nation. JTF-SD conducts, in unified action with mission partners, space superiority operations to deter aggression, defend U.S. and allied interests, and defeat adversaries throughout thecontinuum of conflict.[2][28]
In August 2020, In the meeting of the National Space Council, acting Director of National Intelligence announced ''in case of an attack on the U.S. satellites the operational control of intelligence community assets will be in the ambit of the military'', resulting in theNational Reconnaissance Office being operationally subordinated to the commander of U.S. Space Command in matters of space defense.[29]

On 24 August 2021, two years after its establishment, U.S. Space Command announced that it had reachedinitial operating capability.[30] Achievingfull operating capability, according to Lieutenant GeneralJohn E. Shaw, deputy commander of U.S. Space Command, is dependent on the selection of the combatant command's permanent headquarters.[31]
U.S. Space Command is planning to reorganize its subordinate commands, possibly reactivating theJoint Force Space Component Command (JFSCC), the precursor organization of the combatant command. JFSSC is planned to be the combatant command's "primary warfighting command," formed by combining CFSCC and JTF–SD. Space Force Lieutenant GeneralStephen Whiting, commander of SpOC, is planned to lead the new organization.[32]
In 2023, U.S. Space Command regained its responsibility for missile defense from U.S. Strategic Command and will be taking over theJoint Functional Component Command for Integrated Missile Defense.[33]
In January 2021, it was announced thatRedstone Arsenal in Huntsville, Alabama was the preferred final location for U.S. Space Command. The other locations in contention wereKirtland Air Force Base,Offutt Air Force Base,Joint Base San Antonio, its interim location atPeterson Space Force Base, andPatrick Space Force Base.[34] DespitePeterson Space Force Base in Colorado being both the original and interim location of Space Command headquarters, Redstone Arsenal was selected, reportedly due to political pressure directly from then-president Donald Trump.[35] A formal review from theDepartment of Defense Inspector General was initiated to ensure the process that selected Huntsville as the preferred location was impartial and factually sound. FormerSecretary of Defense Lloyd Austin came out with his public support and backed the Department of the Air Force's decision process which resulted in the selection of Redstone Arsenal.[36] In May 2022, the review found that the selection of Redstone Arsenal as the permanent site was reasonable and justified.[37][38] In July 2023, the move to Huntsville was cancelled. GeneralJames H. Dickinson, USA, Commander of the U.S. Space Command, argued that moving the headquarters to Alabama from its current location in Colorado Springs would hurt military readiness. Republicans have accused the Biden administration of acting due to a partisan standoff over the Pentagon's abortion access policies at the time.[39]
Relocation discussions intensified in early 2025, with the change in administrations. U.S. Rep.Mike Rogers (R-Ala.), who chairs the House Armed Services Committee, predicted an announcement by the end of April, but no such statement was issued. On 2 May 2025, two sources told a Huntsville television station that a decision had been reached to move USSPACECOM to Redstone Arsenal and -- barring a reversal -- the announcement would follow confirmation of a new Secretary of the Air Force.[40] On 2 Sep 2025, PresidentDonald Trumpannounced in the Oval Office that the headquarters will be moved to Huntsville, Alabama.[41]

Previous, now-deactivated functional components included theCombined Force Space Component Command atVandenberg Space Force Base, California, and theJoint Task Force–Space Defense atSchriever Space Force Base, Colorado. Both were disestablished with the creation of U.S. Space Forces – Space to take on SpOC's Space Force responsibilities.[49]
United States Space Command is theunified combatant command for all military space operations, while theUnited States Space Force is the military service responsible for organizing, training, and equipping the majority of forces for U.S. Space Command. Space Command's Space Force service component isSpace Operations Command, providing the majority of space forces.[50] U.S. Space Command also consists of smaller amounts of forces from theUnited States Army,United States Marine Corps,United States Navy, andUnited States Air Force. This mirrors the relationship between the Space Force's predecessor,Air Force Space Command, and U.S. Space Command (and between 2002 and 2019,United States Strategic Command).[51]
Shield: Thebald eagle, a traditional symbol of American strength and vigilance, carries an olive branch in his right talon, symbolizing the worldwide goal of peaceful operations in space. In his left talon is a cluster of thirteen arrows with the silver delta as arrowheads, indicative of the strength and power necessary to protect our citizens and allies. Thedelta symbol is historically associated with space and represents change and innovation, and the cluster of deltoids thrusting upward into space signifies our ever growing aspirations in space beyond earth’s orbit. The blue globe with silver land masses, as viewed from space, signifies the origin and control point for all space assets and represents the global operations of the command in mission areas such as surveillance, navigation, communications and missile warning. The silver and white Polaris signifies our constant presence and vigilance in space now and in the future. Encompassing the globe are two white elliptical orbits representing the unity of U.S. Space Command with our joint and combined partners, and which intersect over the United States, the terrestrial heart of the command. An arc of four silver stars above the eagle symbolizes the four-star combatant commander of U.S. Space Command. The black background represents the infinity of space.
Seal: The coat of arms as blazoned in full color on a black disk, bearing the night sky, enclosed by a silver border, and inscribed "UNITED STATES" above and "SPACE COMMAND" below, all silver.
Black and gold together symbolize the United States Army. Black signifies the vast infinity of space and gold denotes high standards for excellence. The demi-globe represents the earth as seen from space and symbolizes the global operations of the command. The crossed orbital rings denote the unity of United States Space Command (USSPACECOM) with joint and combined partners. The rings intersect over the United States, identifying the terrestrial heart of the command. The gold pheon represents the combat power of Army Space. Four stars represent the four-star combatant commander of USSPACECOM. The Polaris star signifies constant presence and vigilance in space now and into the future.[52]
