The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two units of a flight-critical light assembly, identified by NSN 1R-1680-016099071-P8 and reference number 417A5460-13. This procurement requires Government source approval prior to contract award, as the item is deemed critical for flight operations, and only previously approved sources will be considered for this solicitation. Interested vendors must submit comprehensive technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to provide the required information will result in disqualification from the award process. For further inquiries, interested parties can contact Jessica L. Harpel at (215) 697-2995 or via email at JESSICA.HARPEL@NAVY.MIL.
