The U.S. Army is seeking sources to manufacture and repair PATRIOT Cooler Liquid Electron Tube (CLET) Pumps for both domestic and Foreign Military Sales, specifically for part numbers 11463449-2 and 11463449-3, or comparable alternatives that meet fit, form, and function. Responses are due 35 days after the RFI release, with a two-week window to request the Technical Data Package (TDP) and an additional two weeks to respond after receiving it. No specific budget amount is mentioned, and the performance location is not specified, though the contracting activity is at Redstone Arsenal, Alabama. The government may conduct a pre-award survey and require product acceptance, configuration audits, and qualification testing to minimize program risk. This is a market research effort only, not a solicitation, and no contract award will result directly from this RFI.
