The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 12 units of the Mounting Base, Electric (NSN 7R-5975-016098939-P8, REF NR 822-1211-001). 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 and manufacturing knowledge are not readily available to the Government. Interested parties must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with the primary contact for inquiries being Shannon R. Menickella at (215) 697-2198 or via email at SHANNON.R.MCNEILL.CIV@US.NAVY.MIL.
