This Sources Sought Synopsis is for market research only, and no solicitation is currently available. The Defense Logistics Agency at Redstone Arsenal, Alabama, is seeking qualified manufacturing/supply sources for a CYLINDER ASSEMBLY,A, NSN 1650-01-263-7856, Part Number 7-318000011-5, in support of the A-BJ weapon system. The applicable NAICS code is 336413 with a 1,250-employee size standard, and all business categories—including 8(a), small, small disadvantaged, SDVOSB, HUBZone, and women-owned concerns—are invited. Because the Government does not own or hold rights to the required data and reverse engineering is uneconomical, the acquisition is currently being pursued under FAR 6.302-1 with a limited number of responsible sources. Contractors must meet prequalification/source-approval requirements and be capable of recurring and nonrecurring engineering plus all manufacturing/production aspects, including supply chain management, logistics, forecasting, long-lead procurement, obsolescence issues, and final delivery.
