The United States Space Force (USSF) is the space warfare service branch of the U.S. Armed Forces, and is one of the eight U.S. uniformed services. The sixth and youngest branch of the U.S. Armed Forces, it was the first branch of the military established since the formation of the independent U.S. Air Force in 1947. The direct antecedent of the Space Force, Air Force Space Command, was formed on 1 September 1982 with responsibility for space warfare operations. The National Defense Authorization Act for 2020 redesignated Air Force Space Command as the U.S. Space Force, and established it as an independent branch of the U.S. Armed Forces on 20 December 2019.

The U.S. Space Force is organized as a military service branch within the Department of the Air Force, one of the three military departments within the Department of Defense. The Space Force, through the Department of the Air Force, is headed by the Secretary of the Air Force, who reports to the Secretary of Defense, and is appointed by the president with Senate confirmation. In terms of personnel count, it is the smallest U.S. armed service within the U.S. Department of Defense.
The most senior Space Force officer is the Chief of Space Operations, unless a Space Force officer also serves as either the chairman or vice chairman of the Joint Chiefs of Staff. The Chief of Space Operations exercises supervision over the Space Force's units and serves as one of the Joint Chiefs of Staff. Certain Space Force components will be assigned, as directed by the Secretary of Defense and Secretary of the Air Force, to unified combatant commands. Combatant commanders will be delegated operational authority of the forces assigned to them, while the Secretary of the Air Force and the Chief of Space Operations will retain administrative authority over their members.
