The Department of Defense, specifically the U.S. Army Contracting Command-New Jersey, is conducting a market survey to identify potential sources capable of manufacturing base bleed propellant grains for the M1128 HE Artillery projectile program. The objective is to assess the ability of interested parties to produce 5,000 to 10,000 base bleed grain assembly units per month, which are critical for enhancing the range of conventional artillery systems compatible with platforms like the M777A2 and M109A7. Interested vendors must demonstrate their production capabilities, provide a rough order of magnitude cost estimate, and confirm their ability to meet stringent storage and quality assurance requirements. Responses to this Sources Sought notice are due by April 22, 2025, and should be directed to the primary contact, Ms. Mary O'Connell, at mary.p.oconnell3.civ@army.mil.
