About this agency
The Defense Threat Reduction Agency (DTRA), a Defense Department sub-agency under the Under Secretary of Defense for Acquisition and Sustainment, designs and executes DoD programs to counter weapons of mass destruction, reduce nuclear threats, and conduct applied research and development supporting U.S. and allied warfighters — procuring across R&D, software integration, robotics, cyber analytics, and specialized equipment through both full and competitive acquisitions.
DTRA has awarded 26,353 federal contracts totaling $34.4 billion in combined potential value since 1978, with $32.47 billion obligated against that ceiling. Contract activity over the last five years averaged 214 awards in 2022, 238 in 2023, 223 in 2024, 197 in 2025, and 94 year-to-date in 2026. The most recent recorded award closed on September 8, 2026. Across the portfolio history, 4,496 distinct prime contractors have been awarded. Contract competition is highly fragmented: the top five primes by award count hold 11 percent of recent awards, while the top five by potential value hold 7 percent. Applied Research Associates, Inc. leads both rankings with 50 awards and $1.22 billion in combined potential value over the last five years. Booz Allen Hamilton Inc., Leidos, Inc., Teksynap Corporation, and Valiant Global Defense Services Inc. round out the by-value top five. Eighty-nine percent of awards carry no set-aside designation; 8 percent are small-business set-asides (primarily unrestricted small-business awards), 1 percent are competitive or sole-source 8(a), and the remaining 2 percent are split among SDVOSB, HUBZone, WOSB, and allied categories.
Recent contract opportunities reflect DTRA's technical remit: a notice of intent to sole-source a Custom Integrated Robotic System to Rocky Mountain Unmanned Systems (solicitation PWS-RD-TS-TSE, due October 22, 2026) requiring R&D design, integration, and delivery of a prototype capable of autonomous navigation and 3D hazardous-atmosphere mapping; a sole-source notice for Mobile Cyber Analytic Toolkits to NextCom LLC (HDTRA126Q0043, due September 23, 2026); a request for information on CBRN-capability operational user trials scheduled for March 2027 (SCOUT27, RFI due October 9, 2026); and a small-business set-aside for archival display cases (HDTRA126Q0028, due September 3, 2026).
DTRA has awarded 925 federal grants totaling $1.36 billion in federal dollars obligated since 2006, with activity declining over the last five years: 42 awards in 2022, 20 in 2023, 20 in 2024, 8 in 2025, and 7 year-to-date in 2026. The most recent grant award closed on June 1, 2026. Among 258 distinct recipients, grant funding is fragmented: the top five by award count hold 25 percent of recent awards, while the top five by federal dollars hold 6 percent. The World Health Organization (7 awards, $16.5 million federal obligated) and Food And Agriculture Organization Of The United Nations (6 awards, $29.8 million federal obligated) lead by award count; FAO leads by federal dollars. Grants are predominantly Project Grants (94 percent of awards), with Block Grants (4 percent) and Cooperative Agreements (2 percent) representing smaller shares.
