This opportunity is for the acquisition of a single unit of a flight-critical part (NSN 1R-1680-015416640-V2) that requires Government source approval prior to award, as only previously approved sources have been solicited. The part requires engineering source approval from the design control activity, and the approved source(s) retain essential technical data and manufacturing knowledge that is not economically available to the Government. Delivery is FOB Origin, and the Government intends to solicit and negotiate with only one source under the authority of FAR 6.302-1. If you are not an approved source, you must submit all data required by the NAVSUP WSS Source Approval Brochure with your proposal, as offers failing to do so will not be considered. No specific budget amount or performance location is mentioned in the description.
