Assistant Secretary of Defense for Research and Engineering

The Assistant Secretary of Defense for Research and Engineering (ASD(R&E)) is a senior official of the United States Department of Defense. The ASD(R&E) and the office s/he heads are charged with the development and oversight of DoD technology strategy for the DoD. The ASD(R&E) reports to the Under Secretary of Defense for Acquisition, Technology and Logistics (USD(AT&L)). The post (or effectively the same post) has at various times had the titles Under Secretary of Defense, Research and Engineering (USDR&E), or Director of Defense Research and Engineering (DDR&E). The latter title has itself historically varied between the rank of Under Secretary and that of Assistant Secretary.

ASD(R&E) is the principal staff advisor for research and engineering matters to the USD(AT&L), and also the Secretary and Deputy Secretary of Defense. In this capacity, ASD(R&E) serves as the Chief Technology Officer (CTO) for the Department of Defense charged with the development and oversight of DoD technology strategy in concert with the Department’s current and future requirements. The goal of ASD(R&E)is to extend the capabilities of current war fighting systems, develop breakthrough capabilities, hedge against an uncertain future through a set of scientific and engineering options and counter strategic surprise. In cooperation with the Deputy Under Secretary of Defense for Acquisition and Technology (DUSD(A&T)), ASD(R&E) also provides advice and assistance in developing policies for rapid technology transition.

As of July 2009, DDR&E introduced four areas of focus in support of the immediate and future needs of the DoD:

The National Security Act of 1947 and its 1949 amendments established the Department of Defense, including the establishment of two statutory boards, a Munitions Board, and a Research and Development Board. In June, 1953, President Eisenhower’s Reorganization Plan No. 6 abolished the boards as such, and created six new Assistant Secretaries of Defense, two of which were predecessors to the current ASD(R&E): ASD (Applications Engineering) and ASD (Research and Development). Some time later, the Applications Engineering position became simply Engineering.

In March 1957, the two related ASDs were combined to become the Assistant Secretary of Defense, Research and Engineering, ASD(R&E). Then, under the DoD Reorganization Act of 1958 (PL 85-599, effective August 6, 1958), the position of ASD(R&E) was abolished and replaced by a new Director of Defense Research and Engineering (DDR&E), with the higher rank of Under Secretary.
