The effort is structured in two phases, with Phase I lasting 12 months and focusing on synthesis capabilities. Research limited to inorganic materials or incremental improvements to existing state-of-the-art practices is specifically excluded. Awards will be issued as Other Transaction for Prototype Agreements, with payments processed through the Wide Area Workflow system based on a schedule of milestones. Proposals are due by December 18, 2026, via the Broad Agency Announcement Tool and must include technical, management, and pricing volumes. Eligibility is restricted to U.S. organizations, and all performers must comply with CMMC Level 2 self-certification and NIST SP 800-171 standards for safeguarding Controlled Unclassified Information. Evaluation will be based on technical approach, relevance to the DARPA mission, budget realism, and the capability to transition the technology to military or commercial sectors.

The 2014 Quadrennial Defense Review established innovation as a central line of effort in the national defense strategy of the United States. The decisive military advantage of the United States over its adversaries and peer competitors is steadily eroding. Consequently, under 10 U.S.C. 3458, Contracting Officers may acquire innovative commercial items, technologies, or services using a competitive procedure called a Commercial Solutions Opening (CSO). Under a CSO, the Department of Defense may competitively select proposals received in response to a general solicitation, similar to a broad agency announcement, based on a review of proposals by scientific, technological, or other subject-matter expert peers. Use of a CSO in accordance with Defense Federal Acquisition Regulation Supplement Subpart 212.70 is considered to be a competitive procedure for the purposes of 10 U.S.C. 221 and Federal Acquisition Regulation (FAR) 6.102. Finally, Contracting Officers shall treat items, technologies, and services acquired using a CSO as commercial products and commercial services. Contracts or agreements under this authority shall be fixed-price, including fixed-price incentive fee contracts.
