Space Force

The mission of the United States Space Force (USSF) is to:

• Secure national interests: Protect American interests in space, and the space capabilities that support the Joint Force.
• Provide freedom of operation: Ensure the United States can operate freely in space.
• Conduct space operations: Carry out space operations.
• Build and protect military space assets: Develop offensive capabilities and protect the military's space assets.
• Keep space secure: Maintain a stable and accessible space for military space power and innovation.

The USSF was established on December 20, 2019, and is the sixth military branch of the U.S. Armed Forces. The members of the Space Force are called Guardians, a term that comes from the motto of Air Force Space Command, the organization that eventually became the USSF.

The USSF's statutory responsibilities are outlined in 10 U.S.C. § 9081. The Space Force's symbol is the delta, which honors the heritage of the U.S. Air Force and Space Command.
