The Department of Defense, specifically the Naval Surface Warfare Center (NSWC) Crane Division, is seeking information from industry sources regarding the development of a detonator that incorporates a high voltage switch/spark gap and an exploding foil initiator (EFI). The objective is to identify vendors capable of manufacturing EFI detonator components that meet stringent environmental, electrical, and performance specifications, ensuring reliability and cost-effectiveness in production. This initiative is crucial for advancing military capabilities in munitions technology. Interested parties must submit their responses by July 3, 2025, at 4:00 P.M. EDT, and can direct inquiries to Derek S. Perry at derek.s.perry2.civ@us.navy.mil. Please note that no funding is currently available for this effort, and responses will be used solely for market research purposes.
