AI Contract Overview
The Defense Threat Reduction Agency (DTRA) has issued a five-year Broad Agency Announcement (BAA) running from 2022 through 2026 under solicitation number HDTRA122S0002, designed as a continuous vehicle for releasing targeted technology topics as they become available. This BAA seeks proposals for research and development projects at Technology Readiness Levels (TRL) 3 to 6, with the expectation that successful efforts will reach TRL 4 to 6 by project completion, including attention to Manufacturing Readiness Levels (MRL) for applicable technologies. The initiative supports DTRA’s mission to advance defense capabilities against chemical and biological threats by identifying innovative science and technology solutions that can be transitioned into joint acquisition programs. Topics are released in sequential calls, each with specific deadlines for questions and proposals; recent updates include Topic Call 7 with a proposal deadline of September 2, 2026 at 2:00 PM EDT and a question submission deadline of July 22, 2026, following prior calls with their own respective deadlines through 2024 and 2023. The BAA remains open throughout its five-year term, allowing ongoing submissions under newly released topics. Proposals must align with DTRA’s Chemical and Biological Defense (CBD) program objectives, which respond to evolving military threats, operational needs, and national defense strategies. The agency supports both intramural and extramural research to maintain cutting-edge capabilities. Amendments have been periodically issued to revise sections of the BAA, including updates to sections 4.8.2.3.1, 4.8.2.3.8, and 9.0, as well as the addition of section 4.8.2.3.17, and revisions to Attachments 6 and 7. Questions and answers for multiple topic calls have been published to clarify requirements and ensure transparency. All proposals must be submitted electronically through the SAM.gov portal, with inquiries directed to the official DTRA RD-CB BAA mailbox. The office is located at Fort Belvoir, Virginia, and the opportunity is categorized under NAICS code 5417, targeting research and development services in the physical, engineering, and life sciences.

The purpose of this BAA is to serve as a five-year (60-month) open continuous vehicle through which topics will be released as individual calls as they become available during the BAA open period. This BAA will remain open for five years from the date of release.
The scope of this BAA is limited to projects that meet Technology Readiness Level (TRL) definitions in the TRL range of 3-6 (see ATTACHMENT 1 for TRL definitions). Upon completion of the proposed development efforts, solutions should strive to meet a TRL in the range of 4-6. Proposals that address technologies at TRL 4 or greater should also be aware of the Manufacturing Readiness Level (MRL) considerations.
The DTRA RD-CB mission was established by the Department of Defense (DoD) to provide state-of-the-art defense capabilities to allow military forces of the United States to operate and to successfully complete their missions in chemical and biological warfare environments. The scope of mission efforts and the priorities assigned to specific projects are influenced by changes in military and civilian Chemical and Biological Defense (CBD) science and technology, advanced developments, operational requirements, military threat assessments, and national defense strategies. To keep pace with defense capability requirements, the CBD Program (CBDP), as part of its mission, routinely promulgates chemical and biological research. The comprehensive research program encompasses both intramural and extramural sources, and the role of each is vital to the fulfillment of the CBDP objectives.
DTRA is seeking optimum approaches to meet technology objectives with a goal to identify and select science and technology projects that can be transitioned to joint acquisition programs.
