Structure of the United States Space Force

The structure of the United States Space Force consists of four main bodies: the Office of the Secretary of the Air Force, the Space Staff, the field commands, and the space deltas.
The Space Force is organized as one of two coequal military service branches within the Department of the Air Force, with the other service being the United States Air Force. Both services are overseen by the secretary of the Air Force, who has overall responsibility for organizing, training, and equipping the Space Force and Air Force.
The military head of the Space Force is the chief of space operations (CSO), who is an officer in the grade of general.
Space Staff.
The Space Staff is the headquarters of the U.S. Space Force. Like the U.S. Air Force's Air Staff that is under the Department of the Air Force, it is overseen Office of the Secretary of the Air Force. It is responsible for developing doctrine, guidance, and plans in performing the Space Force's functions, cooperating with the Air Staff on support issues. It composes of the military service's most senior leaders: the chief of space operations, the vice chief of space operations, and the chief master sergeant of the Space Force. Like the other services, there is a director of staff who oversees the synchronization of policies and plans of the headquarters staff and three deputy chiefs of space operations.
The Space Staff was designed to be lean. Compared to the Air Force's nine headquarters directorates, the Space Force merged nine functional areas into three directorates. Additionally, each of the three deputy chiefs of space operations has unofficial positional titles akin to that of corporate organizations: chief human capital officer, chief operations officer, and chief strategy and resourcing officer. The chief human capital officer is held senior civilian official, while both the chief operations officer and chief strategy and resourcing officer positions are filled by two lieutenant generals. Also, a chief technology and innovation officer position is currently filled by Major General Kimberly Crider who is also the mobilization assistant to the chief of space operations.
Field organization.
The Space Force field organizations consist of three different echelons of command: field commands, deltas, and squadrons. Field commands align with specific mission focuses and are led by officers in the grade of lieutenant general or major general. Deltas are organized around a specific function, such as operations, installation support, and training, and are led by an officer in the grade of colonel. Squadrons are focused on specific tactics and are led by an officer in the grade of lieutenant colonel.

Field commands.
The Space Force's three field commands will be Space Operations Command (SpOC), Space Systems Command (SSC), and Space Training and Readiness Command (STARCOM). Space Operations Command will be the primary force provider of space forces and capabilities and commanded by an officer in the grade of lieutenant general (Stephen N. Whiting). SpOC was activated at Peterson Air Force Base in the summer of 2020. The current Space Operations Command, formerly 14th Air Force, has been renamed Space Operations Command West. Space Systems Command will be responsible for developing, acquiring, and fielding space systems, as well as launch, developmental testing, on-orbit checkout, and sustainment and maintenance of space systems. It will also run Space Force science and technology activities. Led by an officer in the grade of lieutenant general, SSC will be formed from the Space and Missile Systems Center, Commercial Satellite Communications Office, and other space systems programs offices transferred into the Space Force. Space Training and Readiness Command will train and educate space professionals, and develop combat-ready space forces. While STARCOM will be led by an officer in the grade of major general, it will not be activated until 2021. In the interim, a Space Training and Readiness Delta will be established in July at Peterson AFB.
On 20 December 2019, Air Force Space Command's principal components were 14th Air Force (Air Forces Strategic) and the Space and Missile Systems Center. At the same time as the creation of the Space Force 14th Air Force was redesignated as Space Operations Command.
Planned transfers.
On 12 March 2019, the Space Development Agency (SDA), a new space-focused development agency, additional to the Space and Missile Systems Center and the Space Rapid Capabilities Office, was established. It was established under the authority of the under secretary of defense for research and engineering. As of January 2020, the SDA is planned to become part of the U.S. Space Force in October 2022.
In early April 2020, a list of twenty-three units to be transferred from the Air Force to the Space Force was publicly reported. Those units included the 17th Test Squadron, Peterson Air Force Base, Colorado; 18th Intelligence Squadron, Wright-Patterson AFB, OH; the 25th Space Range Squadron, Schriever AFB, CO; the 328th Weapons Squadron, Nellis AFB, NV; the 527th Space Aggressor Squadron, Schriever AFB, CO; the 7th Intelligence Squadron, 659th Intelligence, Surveillance and Reconnaissance Group, 70th ISR Wing, Ft. Meade, Maryland*; Sixteenth Air Force/Advanced Programs*, Schriever AFB, Colorado; the 32nd Intelligence Squadron, Ft. Meade, Maryland*; the 566th Intelligence Squadron, Buckley AFB, Colorado*; the 544th Intelligence, Surveillance and Reconnaissance Group, Group Staff & Detachment 5, Peterson AFB, Colorado; D the 533d Training Squadron, 381st Training Group, Vandenberg AFB, CA (initial training); the Air Force Research Laboratory (AFRL) Research Lab Mission Execution, Wright-Patterson AFB, Ohio*; the AFRL Space Vehicles Directorate, Kirtland AFB, New Mexico*; the AFRL Rocket Propulsion Division, Edwards AFB, CA; the AFRL Electro-Optical Division, Maui, Hawaii & Kirtland AFB, New Mexico*; the AFRL Sensors Directorate, Wright-Patterson AFB, Ohio*; the Counter-Space Analysis Squadron and the Space Analysis Squadron, collectively half of the Space and Missiles Analysis Group, National Air and Space Intelligence Center, both at Wright-Patterson AFB; the Air Force Operational Test and Evaluation Center Detachment 4, Peterson AFB, CO; and the Air Force Safety Center – Space Safety Division, Kirtland AFB, New Mexico. 
Detachment 1, USAF Warfare Center, Schriever AFB, Colorado; Operating Location A, 705th Combat Training Squadron, Schriever AFB, Colorado (ultimately part of the 505th Command and Control Wing), and the National Security Space Institute, Peterson AFB, CO National Security Space Institute, a place for space education became eventually part of the STAR Delta.
