The Director, Science & Technology (S&T) champions the DoD S&T enterprise to maintain oversight and awareness of research and development throughout the Department in areas of basic research, human systems, platforms and weapons technologies, and C5ISR and electronic warfare.

The Director, S&T also serves as the lead for the DoD Communities of Interest (COIs) under Defense Science and Technology Reliance 21. The mission of Reliance 21 is to ensure integrated and coordinated strategic planning for the DoD S&T program. Through the collaborative efforts of COIs and guided by the S&T Executive Committee, Reliance 21 continuously aligns our S&T investments to support the warfighter priorities and capability gaps across the military departments, the joint staff, and defense agencies.

The Director, S&T serves as the Deputy for the US-UK Science and Technology (S&T) Defense Review, also known as the US-UK S&T Stocktake, which 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.

Platforms and Weapons Technology

The Platforms and Weapons Technologies (P&WT) office leads the effort to champion and shape investment in critical enabling technologies for kinetic and directed energy weapons, operational energy, materials and Aerospace Technologies research, and both manned and unmanned systems technologies across the domains of air, land, sea, and space. P&WT Directorates collaborate with the science and technology community to identify science and technology priorities and gaps that enable innovative research and development efforts that meet future force critical warfighting capabilities.


C5ISREW serves as the DoD Science and Technology (S&T) proponent for all Command, Control, Computers, Communications, Cyber, Intelligence, Surveillance, Reconnaissance, and Electromagnetic Warfare (C5ISREW) portfolio technical areas, including: artificial intelligence/machine learning; autonomy & advanced computing; cyber technologies; electromagnetic warfare & countermeasures; nuclear command, control & communications; positioning, navigation & timing; sensors; and software-embedded systems & data analytics.

C5ISREW provides management oversight, policy guidance, technical expertise, and coordination for the S&T programs in the Military Services, Defense Agencies, and COCOMS to ensure the technology base adequately satisfies defense needs. C5ISREW also serves as the DoD focal point for fostering DoD-wide, interagency and international collaboration; leveraging and maturing capabilities; identifying S&T gaps; advocating for S&T investment; and increasing transition opportunities.

Basic research leads to new knowledge. It provides scientific capital. It creates the fund from which the practical applications of knowledge must be drawn. New products and new processes do not appear full-grown. They are founded on new principles and new conceptions, which in turn are painstakingly developed by research in the purest realms of science.

Human Systems

Explore the Human Systems Directorate

In the Human Systems Directorate, we believe that DoD technologies are developed to extend the capabilities of the human, enhance the capabilities of the human, sustain the human, or repair the human.


Explore the HFE TAG site

The major goal of the HFE TAG is to provide a mechanism for the timely exchange of technical information in the development and application of human factors engineering by enhancing the coordination among Government agencies involved in HFE technology research, development, and application. The HFE TAG also assists, as required, in the preparation and coordination of tri-service documents, and sponsors in-depth technical interaction, which aids in identifying HFE technical issues and technology gaps.
