Which organization is responsible for the Sustainment Management System?

The Sustainment Management System (SMS) is primarily overseen by the Air Force Civil Engineer Center (AFCEC) within its Operations branch, which is designated by the "CO" in AFCEC/CO. This organization is responsible for developing and managing sustainment systems that help maintain the operational readiness of Air Force installations. They ensure that resources are wisely allocated and that systems are in place for the continuous support of Air Force missions.

While other organizations have roles in overall sustainment and operational management, AFCEC specifically focuses on the engineering and construction aspects, including the technical and functional support provided by the SMS. The HQ AFIMSC, while involved in various sustainment management issues, does not directly control the Sustainment Management System. Similarly, AFIMSC Detachments at MAJCOMs and AFCENT play significant roles in logistics and operations, but their functions are different from the specific oversight of the SMS managed by AFCEC. Therefore, AFCEC/CO is the correct choice regarding responsibility for the Sustainment Management System.
