Command Priorities

USTRANSCOM command priorities are as follows:

  1. Ready Now and in the Future
  2. Empower a Competitive and Resilient Warfighting Team
  3. Drive Cyber Domain Mission Assurance
  4. Create Decision Advantage


USTRANSCOM is comprised of three Component Commands:

  • The Military Surface Deployment and Distribution Command (SDDC) is a unique Army command that delivers world-class, origin-to-destination distribution solutions. Whenever and wherever soldiers, sailors, airmen, Marines and Coast Guardsmen are deployed, SDDC is involved in planning and executing the surface delivery of their equipment and supplies. SDDC is the Army Service Component Command (ASCC) of the USTRANSCOM Command and is a major subordinate command to Army Materiel Command (AMC). This relationship links USTRANSCOM's Joint Deployment and Distribution Enterprise (JDDE) and AMC's Materiel Enterprise. The command also partners with the commercial transportation industry as the coordinating link between DoD surface transportation requirements and the capability industry provides.
  • Military Sealift Command (MSC) operates approximately 125 non-combatant, civilian-crewed ships that replenish U.S. Navy ships, conduct specialized missions, strategically preposition combat cargo at sea around the world and move military cargo and supplies used by deployed U.S. forces and coalition partners. 
  • The Air Mobility Command (AMC) provides the capability to deploy U.S. armed forces anywhere in the world within hours and help sustain them in a conflict. AMC also supports presidential and senior leader airlift. Air Refuelers are the backbone of Global Reach, increasing coalition and U.S. aircraft’s range mid-air. Aeromedical evacuation ensures the wounded warriors get the care they deserve and today have sustained the survival rate of 97 percent. In addition to enabling the force to respond to an enemy attack and sustain operations, Rapid Global Mobility brings humanitarian supplies and assistance to those in need who may live in austere locations.  AMC’s four core mission areas – Airlift, Air Refueling, Air Mobility Support and Aeromedical Evacuation. AMC also provides support to the nuclear enterprise.

In addition to the three component commands, USTRANSCOM also has two subordinate commands:

  • The Joint Enabling Capabilities Command (JECC) provides mission-tailored, joint capability packages to combatant commanders in order to facilitate the rapid establishment of Joint Force Headquarters (JFHQ), fulfill Global Response Force (GRF) execution and bridge joint operational requirements.
  • The Joint Transportation Reserve Unit (JTRU) augments the USTRANSOM in providing air, land and sea transportation for the DoD, both in times of peace and war.
