The Department of Defense, specifically the U.S. Army Contracting Command – Rock Island, is conducting a market survey to identify sources for the production of 40mm ammunition, with requirements spanning from fiscal years 2027 to 2032. The procurement includes various types of 40mm cartridges, such as the M385A1 Practice Cartridge and several High Explosive Dual Purpose Cartridges, with estimated annual production needs ranging from 30,000 to 5 million rounds. This ammunition is critical for military operations and must comply with U.S. Government Technical Data Packages, with production potentially limited to U.S. and Canadian entities. Interested manufacturers are encouraged to submit their capabilities and background information electronically by May 5, 2025, to the designated contact, Allison Howell, at allison.n.howell2.civ@army.mil, as this market survey is intended for informational purposes only and does not constitute a Request for Proposal.
