The United States Space Force (USSF)

The United States Space Force (USSF) is the space service branch of the United States Armed Forces and part of the civilian-led Department of the Air Force, which is led by the Secretary of the Air Force. The military head of the U.S. Space Force is the chief of space operations, who is assisted by the vice chief of space operations and senior enlisted advisor of the Space Force. It achieved independence on 20 December 2019 from the U.S. Air Force, but directly traces its history through Air Force Space Command to 1 September 1982, with even earlier history traced to the Western Development Division established on 1 July 1954.

The U.S. Space Force is composed of the Regular Space Force, not yet having organized a reserve component outside of the Air Force. The Space Force is organized into three field commands.

The Space Force's field commands are:

· Space Operations Command: Conducts space, cyber, and intelligence operations as primary service component to United States Space Command.

· Space Systems Command: Conducts research, development, acquisitions, and sustainment of Space Force systems.

· Space Training and Readiness Command: Conducts training, education, and doctrine development.

The Space Force's field structure is broken into several subdivisions under its field commands:

 
Delta / Garrison: Consists of two or more squadrons, or attached Air Force mission support and medical groups for garrisons and wings and a Space Force operations group for wings as well, commanded by a brigadier general or colonel. Deltas are responsible for executing a specific mission, while garrisons are responsible for installations support and management. Space Force wings are a legacy organizational structure inherited from the Air Force that manage a singular base and mission under one organization and are being phased out in favor of deltas and garrisons.
 
Squadron: Consist of two or more flights commanded by a lieutenant colonel.
  
Flight / Crew: Consists of individual guardians commanded by a captain, first lieutenant, or second lieutenant.
