This opportunity is for the acquisition of a single unit of a flight-critical part (NSN 1R-9999-LLHPGG898-V2) that requires Government source approval prior to award, with delivery FOB Origin. Only previously approved sources are being solicited, as the part requires unique engineering knowledge and data rights held by the current source that are not economically available to the Government. New sources must submit detailed qualification information per the NAVSUP WSS Source Approval Brochure, and failure to provide all required data will result in the offer not being considered. The Government intends to negotiate with only one source under FAR 6.302-1, but all responsible parties may submit proposals for consideration. No specific budget amount or performance location is mentioned in the description.
