The Under Secretary is appointed from civilian life by the President with the consent of the Senate to serve at the pleasure of the President.

The mission of the OUSD(A&S) is Enable the Delivery and Sustainment of Secure and Resilient Capabilities to the Warfighter and International Partners Quickly and Cost Effectively.^[1]

The Office of the Under Secretary of Defense for Acquisition and Sustainment (OUSD(A&S)) is focused on forming an acquisition system that moves at the speed of relevance, and to do that, has been shaped into an organization that provides a defense-wide adaptive acquisition framework from need identification to disposal. Using data-driven analysis linked with the National Defense Strategy, OUSD(A&S) scales to enable new product and process development and supports a culture of innovation, critical thinking, and creative compliance. There are multiple organizations that fall under OUSD(A&S) that also work towards this goal.^[1]

The Office of the Assistant Secretary of Defense for Acquisition (OASD(A)) ^[2] delivers capability at the point of need through a Defense Acquisition System that is flexible, tailorable, and enables speed. ASD(A) is focused on moving defense acquisition away from being expensive, slow, and burdensome by reducing timelines, lowering costs, and improving quality while rapidly introducing new technology to enhance capability.

The Office of the Assistant Secretary of Defense for Sustainment (OASD(Sustainment)) ^[3] works with logistics and materiel readiness in the Department of Defense (DoD) and is the principal logistics official within the senior management of the DoD. In this capacity, the ASD(S) prescribes policies and procedures for the conduct of logistics, maintenance, materiel readiness, strategic mobility, and sustainment support in the DoD, to include, supply, maintenance, and transportation.

The Office of the Assistant Secretary of Defense for Nuclear, Chemical & Biological Defense Programs (OASD(CNB)) ^[4] leads DoD efforts in preparing for, deterring, and mitigating current and future weapons of mass destruction (WMD) threats. They aim to sustain and modernize the U.S. nuclear deterrent; develop capabilities to detect, protect against and respond to WMD threats; ensure DoD compliance with nuclear, chemical, and biological treaties and agreements; continue to work with allies and partners to strengthen our collective countering weapons of mass destruction (CWMD) capabilities; and advance the United States nonproliferation goals.

The Industrial Policy ^[5] office supports the Under Secretary of Defense for Acquisition and Sustainment by providing detailed analyses and in-depth understanding of the increasingly global, commercial, and financially complex industrial supply chain essential to our national defense.

The Executive Director for Special Access Program Central Office ^[6] facilitates and maintains MOAs and memorandums of understanding for foreign involvement with DoD SAPs and coordinates with appropriate oversight authorities.

International Cooperation (IC) ^[7] Office is to strengthen key international partnerships through cooperative Acquisition & Sustainment initiatives to improve interoperability and sharpen the warfighter’s technological edge. IC prioritizes enabling a lethal, secure, and networked constellation of allies and partners.

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.^[8]

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.^[9][10]
