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 an axial piston pump (NSN 4320-01-118-4428, Part No. 145HS140-10) supporting the CHINOOK weapon system. The applicable NAICS code is 333996 with a 1,250-employee size standard, and all business categories—including 8(a), small, small disadvantaged, SDVOSB, HUBZone, and women-owned small business—are invited to identify themselves. Because the Government does not own and cannot obtain the necessary data rights and reverse engineering is uneconomical, the acquisition is proceeding under FAR 6.302-1(a)(1) with a limited number of responsible sources; contractors must meet prequalification requirements and are encouraged to pursue source approval through AvMC’s public website. The contractor would be responsible for recurring and nonrecurring engineering to become qualified plus all manufacturing/production aspects, including supply chain management, logistics, forecasting, long-lead procurement, obsolescence, and final delivery.
