The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 10 units of the Slide Assembly, identified by NSN 7R-1720-010187536-EY. This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only previously approved sources may submit proposals, as new source approvals cannot be processed in time for the contract award. Interested parties must provide detailed technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, and offers that do not meet these requirements will not be considered. For further inquiries, potential bidders can contact Kimberly Flores at (215) 697-6549 or via email at Kimberly.Flores@navy.mil.
