The Department of Defense, specifically the Air Force Nuclear Weapons Center, is conducting market research to identify potential sources for an impact scoring system to support the Sentinel Program. This system is required to accurately determine the time and position of reentry vehicle impacts, whether at the ocean surface or in the case of an air burst termination, and must have a Technology Readiness Level (TRL) between 6 and 9, indicating it should be mature with minimal need for further development. The information gathered will assist in planning and does not constitute a solicitation for proposals; interested parties are encouraged to request the Statement of Objectives and the Requested Information Form to submit their responses.
