The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of nine units of the AFT AIRCRAFT PANEL ASSY, identified by NSN 1R-1680-015663332-V2 and reference number 901-031-464-149. Due to the flight-critical nature of this item and the lack of adequate technical data for competitive solicitation, only sources previously approved by the Government will be considered for this contract. 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 understanding that the Government may proceed with award based on Fleet support needs if necessary.
