Defense Microelectronics
The Office of Research, Technology, and Laboratories (RT&L) fosters innovation, unparalleled technical expertise, and technological dominance for the Department of Defense through leading-edge S&T research programs, stewardship of laboratories and research institutions, development of a superior S&T workforce, engagement with other government agencies, industry and academia, and cooperation with international allies and partners.
The Office of Science and Technology (S&T) Program Protection promotes enduring warfighter and technological dominance enabled through superior mission systems resilient to exploitation; a competitive, assured national security innovation base; and preservation of technology advancements and practices.
Defense Microelectronics drives rapid modernization of defense systems through access to advanced microelectronics technologies by establishment of: secure design, assembly, packaging, and test capabilities; full lifecycle confidentiality, and integrity; sustainable sources of mission essential technologies; and an invigorated domestic ecosystem to rapidly and securely mature emerging advanced technology.
DTIC collects, disseminates, and analyzes scientific and technical (S&T) information to rapidly and reliably deliver the knowledge base that propels the development of warfighter capabilities. DTIC manages DoD's sole centralized S&T repository of 4.6M+ documents from across the Services and agencies; provides verified users access to unclassified, controlled and classified S&T information; and via the DoD Information Analysis Centers, solves technology challenges through rapid, flexible and low-cost research services.
The Joint Reserve Directorate (JRD) enhances OSD operations and decision-making by providing expertise on emerging and innovative concepts, technologies, strategies, and practices not traditionally available to research and engineering leaders and DoD.
The mission of the Defense Science and Technology Reliance 21 Initiative is to ensure integrated and coordinated strategic planning for the Department of Defense S&T program. Through the collaborative efforts of Communities of Interest and guided by the S&T Executive Committee (S&T ExCom), Reliance 21 continuously aligns our S&T investments to support the warfighter priorities and capability gaps, which the Department can only accomplish through the coordinated efforts of the Office of the Secretary of Defense, the Joint Staff, the Military Departments, and Defense Agencies.
The Technical Cooperation Program (TTCP) is a five-nation, defense innovation network that harnesses science and technology in support of the national defense and security of Australia, Canada, New Zealand, the United Kingdom, and the United States. The US Principal and Deputy within TTCP are provided by DDR&E(R&T).

US-UK Stocktake
The US-UK Science and Technology (S&T) Defense Review, also known as the US-UK S&T Stocktake, strategically directs and balances short- and long-term S&T priorities, responds to emerging threats and opportunities, and ensures that collaborative activities complement those done in wider multilateral engagements. The US Principal and Deputy to the US-UK S&T Stocktake are provided by DDR&E(R&T).
