RFI for Next Generation Hypersonic Cruise Missiles

The Defense Advanced Research Projects Agency (DARPA) Tactical Technology Office is issuing a Request for Information (RFI) to gather industry input for a next‑generation hypersonic cruise missile (NGHCM). The RFI seeks concepts and technology assessments in three focus areas: system‑level trade‑space exploration and digital‑engineering‑enabled concept development; high‑risk, high‑reward critical technology evaluation (e.g., air‑breathing propulsion, high‑energy fuels, advanced materials, thermal management); and innovative test‑and‑evaluation methods to accelerate ground and flight testing. Respondents may address one, two, or all three areas, providing a maximum 15‑page technical description, cover sheet, optional graphic slide, and bibliography. Submissions are electronic, unclassified to DARPA‑SN‑26‑[email protected], with any CUI or classified portions handled per DoDI 5200.48 and NIST SP 800‑171 requirements. No funding or award is indicated; this RFI is purely informational to shape a future competitive solicitation. • Focus Area 1 – Trade‑space exploration, DFMA, digital thread, accelerated schedule. • Focus Area 3 – Critical subsystem technologies (propulsion, fuels, materials, power). • Focus Area 4 – Novel ground/flight test instrumentation, autonomous telemetry, data‑assimilation, range‑safety concepts. • Submission limit = 15 single‑sided pages; deadline = Nov 6 2026 5 PM ET. • Open to all capable sources (industry, academia, labs, non‑traditional contractors).
