The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 22 units of the NSN 7R-2840-000811987-FQ, identified as CASE AND NOZZLE ASS. 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 typically cannot be processed in time to meet government needs. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and offers lacking the required data will not be considered. For further inquiries, potential bidders can contact Sophia J. Noel at (215) 697-4313 or via email at SOPHIA.NOEL@NAVY.MIL.
