The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 8 units of a flight-critical cooler, identified by NSN 0Q-2840-016666864-B8. The procurement requires that only approved sources may submit proposals, as the Government does not possess sufficient data to purchase this item from other than the current sources, necessitating Government source approval prior to contract award. This item is crucial for operational readiness, and interested vendors must provide detailed technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures to be considered for the award. For inquiries, potential bidders can contact Charles F. Horan at (215) 697-1303 or via email at CHARLES.F.HORAN4.CIV@US.NAVY.MIL.
