High Mach Gas Turbine (HMGT) Technologies Special Notice

DARPA's Aerospace Projects Office (APO) is hosting an Industry Day on September 17, 2025, to inform potential proposers about the High Mach Gas Turbine (HMGT) Technologies program. This initiative, part of DARPA's Next Generation Responsive Strike (NextRS) Initiative, seeks to advance reusable hypersonic aircraft technologies by developing an advanced gas turbine engine capable of operating at higher Mach numbers. Phase 1, led by DARPA APO in partnership with AFRL and AFLCMC/LP, will focus on conceptual and preliminary design, subsystem/component testing, and developing a technology roadmap. Future phases are expected to lead to a HMGT engine prototype and full-scale testing. Registration, which closes on September 9, 2025, is required and attendance is voluntary. The event will be classified at the SECRET level, requiring security clearance and government-issued photo identification for entry. No electronic devices, recording, or photography will be permitted.

DARPA's Aerospace Projects Office issued a Broad Agency Announcement (BAA) for a High Mach Gas Turbine (HMGT) Engine Design Study. This initiative, part of the Next Generation Responsive Strike (NextRS), seeks to advance reusable hypersonic aircraft technologies. The BAA (HR001125S0016), posted on September 16, 2025, outlines Phase I for conceptual and preliminary HMGT engine design, with an anticipated $10M for Phase IA (6 months) and $30M for Phase IB (9 months). Multiple awards are expected, with abstracts due by October 15, 2025. The project aims to develop a HMGT engine compatible with future hypersonic aircraft, focusing on architecture definition, conceptual design, and technology roadmapping. Evaluation criteria prioritize scientific merit, proposer capabilities, and relevance to DARPA's mission. Classified attachments require specific security protocols.
