The U.S. Army announced on Thursday the establishment of its newest branch, the Space Operations Branch, to formalize career paths for space professionals and strengthen integration of space capabilities into land operations.
The final frontier, now an Army branch.
We're proud to announce the new U.S. Army Space Operations Branch, solidifying our role as leaders in the space domain and ensuring our Soldiers have the advantage from the ground to the stars.

The branch consolidates Functional Area 40 (FA40) Space Operations Officers with the new enlisted Military Occupational Specialty (MOS) 40D Tactical Space Operations Specialist. It supports the Army’s multidomain operations concept by delivering space-based effects directly to tactical units while enabling counterspace capabilities, per the announcement.
Why the Army Created the Branch
The Army is the largest user of space capabilities in the joint force, relying on them for positioning, navigation, timing (PNT), satellite communications, intelligence, surveillance, reconnaissance, missile warning, and environmental monitoring. Growing threats from adversaries seeking to disrupt or deny these capabilities drove the need for dedicated expertise.
Prior to the branch, enlisted personnel supporting space missions came on temporary assignments from branches such as Air Defense Artillery, Signal, and Military Intelligence, then returned after about three years. This created gaps in specialized knowledge. The new structure builds a permanent career path and a dedicated noncommissioned officer corps.
“The Army is the largest user of space capabilities in the joint force, and space integration is absolutely critical to multidomain operations at every echelon,” said Lt. Gen. John Rafferty, commanding general, U.S. Army Space and Missile Defense Command (USASMDC). “Establishing the Space Operations Branch is an important step in the Army’s continuous transformation. It provides the Army with the professional structure to deliver space-based effects directly to our Soldiers and units at the tactical edge enabling commanders to fight and win in a contested, multidomain environment.”
Objectives and Capabilities
The Space Operations Branch focuses on two pillars: integration of friendly joint and coalition space capabilities and interdiction of adversary space capabilities in support of land forces. This includes counter-SATCOM, counter-surveillance and reconnaissance, and navigation warfare.
Space professionals advise commanders on space effects across warfighting functions, plan integration into military decision-making processes, and operate in contested environments. The branch supports multidomain task forces and theater strike effects groups.
It relieves pressure on other branches by allowing the redistribution of personnel while ensuring space formations have experienced soldiers. The Army forecasts an initial need for about 1,000 40D billets, potentially growing to 1,500 by 2032.
How Enlisted Soldiers Can Get Involved
Effective October 1, 2026, the Army will establish MOS 40D Tactical Space Operations Specialist for enlisted soldiers in grades E-4 through E-9 across the active duty, National Guard, and Reserve components. Applications for the initial selection board run from January 1 to April 30, 2026. Selected soldiers attend formal training at the U.S. Army Space and Missile Defense School in Colorado Springs, Colorado.
“Army space Soldiers must be on the ground to provide effects to the warfighter and operate in deep enemy and extended deep areas,” said Command Sgt. Maj. John Foley, USASMDC command sergeant major. “That is the distinct difference that only Soldiers can do for our Army.”
Soldiers must qualify for a Top Secret clearance. Details, including assignment locations and MILPER Message 26-028, are available on the Army Space Knowledge Management SharePoint site.
Officers continue to pursue the FA40 designation through existing processes, with training also at the Space and Missile Defense School.
Future Impacts
The branch professionalizes space expertise at all echelons, from tactical units to joint and interagency roles. It enables closer integration of space effects with cyber, electronic warfare, and fires in multidomain operations. By building retained talent, the Army aims to maintain an advantage in a domain where adversaries actively contest U.S. access.
Collaboration with NASA
The branch maintains ties to civil space efforts. FA40C Army Astronauts are detailed to NASA for human spaceflight programs under existing memoranda of understanding. The USASMDC manages the Army NASA Detachment at Johnson Space Center in Houston, where space operations officers provide expertise to NASA missions while gaining insights applicable to military needs.
Training and Structure
Training leverages existing pipelines at the Space and Missile Defense School. The branch operates under USASMDC oversight, with billets across operating and generating force positions, including support to U.S. Space Command and other joint entities.
Gen. Christopher LaNeve, U.S. Army Vice Chief of Staff, noted the professional focus, stating, “Land power requires warfighting expertise in all domains. What makes me proud is that our Army is not just building a capability, we’re growing professionals at every echelon.”
