From the Overview: "In the Department of Homeland Security (DHS), the Directorate of Science and Technology (S&T) has primary responsibility for establishing, administering, and coordinating research and development (R&D) activities. The Countering Weapons of Mass Destruction Office (CWMDO) is responsible for R&D relating to detection of nuclear and radiological threats. Several other DHS components, such as the Coast Guard, also fund R&D and R&D-related activities associated with their missions. The Common Appropriations Structure that DHS introduced in its FY2017 budget includes an account titled Research and Development in seven different DHS components. Issues for DHS R&D in the 116th Congress may include coordination, organization, and impact."
