The Air Force Research Laboratory (AFRL) is seeking information on technologies and platforms for high-cadence, recoverable hypersonic reentry experiments, with a focus on payloads that can withstand speeds above 7.5 km/s, acceleration loads exceeding 50 g’s, and thermal loads of at least 2000° C. The goal is to advance science and technology for hypersonic reentry vehicles, including guidance, navigation, avionics, thermal protection systems, and autonomous landing capabilities. AFRL is interested in technologies at TRL 4-5 ready for prototype experimentation, as well as already-developed reentry vehicles available for flight opportunities in the near term (less than 12 months). No specific budget amounts or performance location are mentioned in the description. This is a request for information only, with no end date for submissions, and does not commit the government to any contract.
