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 bearing support, identified by NSN 7R-2840-011314730-TN and reference number 6042T24G01. This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data necessary for full and open competition is not adequately available. Interested parties must provide detailed documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and proposals must be submitted within 45 days of the notice publication, with contact Charles F. Horan available at (215) 697-1303 or via email at CHARLES.F.HORAN@NAVY.MIL for further inquiries.
