The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of three units of the PUMP AUX SCAVAGE AY, identified by NSN 7R-2915-015973485-HP and reference number 23088351. This procurement is critical as the item is flight critical, and the Government does not possess the data or rights necessary to purchase or contract repair from alternative sources, making it uneconomical to reverse engineer. Interested vendors must be approved sources and are required to submit specific documentation along with their proposals, as outlined in the NAVSUP WSS Source Approval Information Brochures. Proposals must be submitted within 45 days of the notice publication, and inquiries can be directed to Alainna M. Pettit at (215) 697-2606 or via email at Alainna.M.Pettit.CIV@us.navy.mil.
