The Department of Defense, specifically the U.S. Army Contracting Command in New Jersey, is seeking information from small arms munitions manufacturers regarding their capabilities to produce high pressure cartridge cases compatible with small caliber ammunition ranging from 5.56mm to .50 caliber. The request for information (RFI) aims to identify contractors who can design and manufacture these cartridge cases at a production rate exceeding one million units per year while meeting stringent performance specifications related to chamber pressure under various temperature conditions. This initiative is critical for ensuring the reliability and safety of ammunition used in military operations. Interested parties must submit their responses electronically in MS Word or PDF format to Nicole L. Mayol at nicole.l.mayol.civ@army.mil by 5:00 PM on May 29, 2025, as this RFI is part of the preliminary market research and does not constitute a formal solicitation.
