The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 9 units of a duct adapter, NSN 7R-1660-016936352-P8, with reference number 708704-1. This procurement is critical as the item is flight critical, and the necessary data for competitive acquisition is not available, necessitating Government source approval prior to contract award. Interested vendors must provide detailed technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, as offers lacking this information will not be considered. Proposals must be submitted within 45 days of the notice, and interested parties can contact Jessica L. Harpel at (215) 697-2995 or via email at JESSICA.HARPEL@NAVY.MIL for further details.
