RFI for Next Generation Hypersonic Cruise Missiles

The Defense Advanced Research Projects Agency (DARPA) Tactical Technology Office has issued Request for Information DARPA-SN-26-93 to gather industry input for the development of a Next Generation Hypersonic Cruise Missile (NGHCM). This RFI is intended to refine technical requirements, validate programmatic assumptions, and inform a future competitive acquisition strategy. The agency is seeking revolutionary concepts and technologies that significantly improve missile performance in areas such as range, speed, and altitude, while prioritizing affordability and manufacturability. The effort focuses on three primary areas: Trade Space Exploration and Concept Development (FA1), Critical Technology Evaluation (FA3), and Innovative Test and Evaluation Technologies (FA4). Responses are due by October 6, 2026, and must be submitted in English, not exceeding fifteen single-sided pages. Submissions should include a technical description addressing the focus areas, a bibliography, and an optional graphic overview slide. Strict security protocols are in place, requiring compliance with DoDI 5200.48 and NIST SP 800-171 for Controlled Unclassified Information (CUI), with specific guidance provided in Attachment 3 for classified submissions. All documents must be clearly labeled with the special notice number, respondent organization, and response title. This is an informational request and does not constitute a formal solicitation for proposals; therefore, no reimbursement will be provided for response costs.
