5/27/25, 9:02 AM FY2022-2026 DTRA Chemical / Biological Technologies Broad Agency Announcement
The Defense Threat Reduction Agency is conducting a five-year Broad Agency Announcement for chemical and biological defense research and development spanning Technology Readiness Levels 3–6, with the most recent topic call (Call 7) having a proposal deadline of September 2, 2026 and questions due July 22, 2026. The BAA has no set-aside and remains open through August 20, 2027.
This is a continuous vehicle releasing topics incrementally. Prior topic calls have closed: Call 1 (August 2022), Call 2 (May 2023), Call 3 (October 2023), Call 4 (May 2024), Call 5 (June 2024), and Call 6 (April 2025). Call 7 addresses two distinct technical areas: CBPD-01 (Advanced Triggers for Autonomous Biological Aerosol Collection) and CBPD-02 (Second Wave, focusing on computational detection of genetically engineered pathogens via metagenomic sequencing). Proposed solutions must strive to achieve TRL 4–6 upon completion; proposals addressing TRL 4 or greater must address Manufacturing Readiness Level considerations.
Eligible sources include industrial and commercial concerns, universities, non-profit organizations, and government-sponsored research centers. DTRA reserves the right to select one or multiple contract awards per topic and intends to award a mix of contract types including cost-reimbursement, fixed-price, other transaction agreements, and interagency agreements. Evaluation considers scientific and technical merit, alignment with DoD Chemical and Biological Defense Program priorities, and capability to perform. Awards for Call 7 are estimated for Government Fiscal Year 2027, fourth quarter. No specific budget ceiling is stated; offerors propose budgets independently with contract duration not exceeding 60 months. NAICS code is 5417 (Scientific Research and Development Services); PSC is AC32 (National Defense R&D Services).
