Quick Summary

The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals for the Mechanisms for Amplification of fusion Reaction Rates in Solids (MARRS) program. This Broad Agency Announcement (BAA) seeks revolutionary advances in amplifying nuclear fusion reaction rates in solids at or near room temperature. The goal is to achieve a predictive understanding of fusion rate amplification for potential future applications like small-scale power generation or non-destructive analysis. Proposals are due March 12, 2026, at 4:00 p.m. ET.

Scope of Work

Proposals should investigate mechanisms for amplifying fusion rates in solids, utilizing theoretical analysis, modeling and simulations (M&S), and experiments. Key areas of focus include materials, fuel loading techniques, and excitation methods. Proposers must incorporate State-of-the-Art (SOA) particle detection technologies and data acquisition systems, present well-defined hypotheses with quantitative rate estimates, and demonstrate multidisciplinary capabilities.

Contract Details

DARPA anticipates making multiple awards, which may include Procurement Contracts, Cooperative Agreements, or Other Transaction Agreements for Research. The anticipated period of performance is 36 months, with a target start date of September 1, 2026. While all responsible sources (U.S. and non-U.S. entities) are eligible, there is no specific set-aside. Historically Black Colleges and Universities, Small Businesses, Small Disadvantaged Businesses, and Minority Institutions are encouraged to submit. Procurement Contracts may require CMMC Level 1 compliance.

Submission & Deadlines

  • Proposal Abstract Due: January 26, 2026, 4:00 p.m. ET
  • Question Submittal Closed: February 23, 2026, 4:00 p.m. ET
  • Full Proposal Due: March 12, 2026, 4:00 p.m. ET

Evaluation Factors

Proposals will be evaluated based on: Overall Scientific and Technical Merit, Potential Contribution and Relevance to the DARPA Mission, Cost and Schedule Realism, and the Proposer's Capabilities or Related Experience.

Key Submission Requirements

Bidders must adhere to specific templates and instructions provided in attachments:

  • Abstract Submission: Mandatory templates in Attachment B (Instructions) and Attachment A (Summary Slide).
  • Technical & Management Volume: Mandatory template in Attachment D, with a page limit of 20 pages.
  • Cost Volume: Mandatory template in Attachment E, requiring the use of the editable Excel spreadsheet (Attachment F) for detailed cost breakdowns. Proposers for Cooperative Agreements should use the SF424 (R&R) Budget form via Grants.gov.
  • Contractual Terms: Review model agreements for Other Transactions (Attachment G) and Cooperative Agreements (Attachment H) for insights into terms, intellectual property, and reporting. An Associate Contractor Agreement (Attachment I) outlines collaboration requirements.
