The US Defense Department leaders will initiate the changes that they can perform without congressional approval for the New US Space Force. President Trump has ordered the creation of a new branch of the military. The US Marines were half-way between the army and the Navy. The Marines were carved out of the army. The Space Force will mostly be taken from the Air Force but will include other existing space satellites and other space-related assets from other military branches.

The Pentagon will take three of the four components of the new Space Force:
* a new combatant command for space,
* a new joint agency to buy satellites for the military
* a new warfighting community that draws space operators from all service branches.

These changes are what can be done before congressional approval.

Creating services and support functions (financial management and facilities construction) will require congressional funding and authorization.

Air Force Space Command (AFSPC) is a major command of the United States Air Force, with its headquarters at Peterson Air Force Base, Colorado. AFSPC supports U.S. military operations worldwide through the use of many different types of satellite, launch and cyber operations.

More than 38,000 people perform AFSPC missions at 88 locations worldwide.
