The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of three units of the CONNECTION MODULE C, identified by NSN 7R-5935-145651780-H1. 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 the technical data for this part is not sufficiently available for open competition. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to do so will result in disqualification from the award process. For further inquiries, potential bidders can contact Raymond J. Kent at (215) 697-2557 or via email at RAYMOND.KENT1@NAVY.MIL.
