Under Secretary of Defense for Acquisition and Sustainment

The Office is the principal staff element for the Department of Defense for acquisitions, advanced technology, and logistics. As the Department's chief administrative officer, the Under Secretary oversees installation management, military construction, occupational health management, utilities and energy management; business management modernization, document services, and nuclear, chemical, and biological defense programs.

The Military Retirement Reform Act of 1986 created the position of Under Secretary of Defense for Acquisition (USD(A)), which was implemented with the issuance of Department of Defense Directive 5134.1 in February 1987. As part of this act, the position of Under Secretary of Defense for Research and Engineering (USD(R&E)) was redesignated as the Director of Defense Research and Engineering (DDR&E), a lower-ranking position which reported to the new USD(A).

The title of USD(A) was changed to Under Secretary of Defense for Acquisition and Technology (USD(A&T)) by the National Defense Authorization Act for Fiscal Year 1994, and the position was later redesignated as the Under Secretary of Defense for Acquisition, Technology, and Logistics (USD(AT&L)) by the National Defense Authorization Act for Fiscal Year 2000. The USD(AT&L) served as the principal assistant to the Secretary of Defense for research and development, production, procurement, logistics, and military construction.[2]

The National Defense Authorization Act for Fiscal Year 2017 removed the position of USD(AT&L), and in its place it created the position of USD(R&E) once again, as well as the new position of USD(A&S). These changes took effect on 1 February 2018. As part of the reorganization, the Assistant Secretary of Defense for Logistics and Materiel Readiness (ASD(L&MR)) and Assistant Secretary of Defense for Energy, Installations, and Environment (ASD(EI&E)) positions were combined into a new Assistant Secretary of Defense for Sustainment.[1][3]

As of the July 2018 reorganization, officials reporting to the USD(A&S) include:[4]
