Transferring to Space Force

Regular Army: Active Duty

Benefit Fact Sheet


The U.S. Space Force (USSF) is the newest branch of the Armed Forces, established on December 20, 2019 with enactment of the Fiscal Year 2020 National Defense Authorization Act. The USSF is a military service that organizes, trains, and equips Service members in order to protect U.S. and allied interests in space and to provide space capabilities to the joint force. USSF responsibilities include developing military space professionals, acquiring military space systems, maturing the military doctrine for space power, and organizing space forces to present to our Combatant Commands.  

Air Force Space Command (AFSPC) was redesignated as the USSF as an initial step in establishing the USSF. Military members that were assigned to AFSPC have now been assigned to the USSF. The Department of Defense (DoD) vision is to consolidate space missions from across the Armed Forces into the USSF, as appropriate and consistent with law. 

The Interservice Transfer program allows qualified individuals from other Uniformed Services to apply for transfer to active duty in the United States Space Force.

The FY23 Interservice Transfer program has closed. 


Regular component Active Duty Officers and Enlisted personnel (Colonels and below) serving in the United States Air Force, Army, Navy and Marine Corps may be eligible.

The Space Force does not have a warrant officer rank structure. Warrant officers may contact a Space Force Recruiter through for OTS information and application procedures.

Benefit Highlights

The Interservice Transfer program (IST) allows qualified individuals from other Uniformed Services to apply for transfer to active duty in the United States Space Force to fill select career fields. All eligible personnel may apply for a transfer. However, some sister service career fields are more desirable for transfer as their training and experience directly correlate with Space Force mission and skill sets. The Specialty Code Crosswalk provides a list of Space Force career field specialty codes and comparable sister service specialty codes.

Interservice transfer requires individuals be discharged from their current enlistment or commission and be enlisted or appointed in the Space Force. Selected applicants are transferred to the Space Force in the grade they currently hold and accrued leave can be carried over as well.

Those selected for IST incur an Active Duty Service Commitment of 4 years.
