The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 40 units of a cooling plate (NSN 7R-2840-012992225-XQ, REF NR 6064T10P01). 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 required for production is not readily available to the Government. The selected supplier will be responsible for ensuring the quality and compliance of the part, with a focus on maintaining the integrity of the design and manufacturing processes. Interested parties must contact Charles F. Horan at (215) 697-1303 or via email at CHARLES.F.HORAN@NAVY.MIL, and proposals must be submitted within 45 days of the notice publication, with specific documentation required for those not already approved as sources.
