The United States Army Space and Missile Defense Command (USASMDC) is an Army Service Component Command (ASCC) of the United States Army. The command was established in 1997.The current USASMDC commander is Lieutenant General Daniel L. Karbler with Senior Enlisted Advisor Command Sergeant Major Finis A. Dodson.

The Army Space Command (ARSPACE) stood up in April 1988 as a field operating agency of the Deputy Chief of Staff (of the Army) for Operations and Plans. As the Army component of U.S. Space Command, ARSPACE was to provide the Army perspective in planning for Department of Defense space support and ensure the integration of Army requirements into joint planning for space support and "conduct planning for DoD space operations in support of Army strategic, operational and tactical missions."

A relatively small organization, it was soon put to the test. The new command was instrumental in bringing space assets to U.S. Army forces during Operation Desert Storm. Following the war, new operational missions, such as the Army Space Support Teams and the Joint Tactical Ground Stations, became key elements of the Army space program.

Organizationally however, ARSPACE remained a command, a Tables of Distribution and Allowances, or TDA, organization with offices and directorates according to mission, rather than an Army operational Table of Organization and Equipment unit. This changed on 1 May 1995. On that date, ARSPACE's Military Satellite Communications Directorate or MILSATCOM Directorate became the 1st Satellite Control, or SATCON, Battalion—the first Army battalion with an operational mission tied to space systems and capabilities.
