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 a lubricating oil tank (NSN 7R-2835-016745668-CL, REF NR 23086193). This procurement is critical as the item is flight critical, and the government does not own the rights to the data necessary for purchasing or repairing this part from additional sources, making it uneconomical to reverse engineer. Interested vendors must be approved sources and are required to submit specific documentation as outlined in the NAVSUP WSS Source Approval Information Brochures; failure to provide the necessary data will result in disqualification from the award process. For further inquiries, interested parties can contact Sophia J. Noel at (215) 697-4313 or via email at SOPHIA.NOEL@NAVY.MIL.
