This is a market research notice from the Defense Logistics Agency at Redstone Arsenal, Alabama, seeking potential manufacturers for a specific lubricating cooler part (NSN 2935-01-112-2978) for the CHINOOK weapon system. The Government does not own the technical data for this part, making reverse engineering uneconomical, so it is currently procured under an exception allowing for a limited number of sources. The agency is interested in identifying all qualified businesses, including various small business classifications, that possess the ability to produce this item. Interested contractors must meet prequalification requirements and will be responsible for all engineering, manufacturing, and supply chain costs associated with becoming an approved source. This notice is for planning purposes only and does not constitute a formal solicitation or commitment to contract.
