DOD has started the process of merging the office responsible for energy and installations with the office responsible for logistics and materiel readiness following the Senate’s confirmation earlier this month of Robert McMahon for the newly created position of assistant secretary of defense (ASD) for sustainment. McMahon, who had been ASD for logistics and materiel readiness, was sworn into his new post Oct. 17. At this point, the department is still carrying out the merger and it has not established a firm date for the office of the ASD for sustainment to be formally established, spokesman Lt. Col. Michael Andrews told On Base. It’s not clear how long the office of the ASD for energy, installations and environment office will remain in place.

The creation of the sustainment office is one of the organizational changes triggered by the Feb. 1 split of DOD’s undersecretary for acquisition, technology and logistics office into two smaller organizations. The new sustainment office will maintain four of the five deputy ASD posts that report to the ASD for energy, installations and environment, but it eliminates the top ASD position from the organization chart, according to a memo issued this summer.
