This opportunity is for the acquisition of a single unit of NSN 6K-8145-012751500-V2, a flight-critical part requiring Government source approval prior to award. Only previously approved sources have been solicited, as the part relies on unique design, engineering, and manufacturing knowledge not economically available to the Government. New sources must submit detailed technical data per the NAVSUP WSS Source Approval Brochure with their proposal, as the approval process cannot delay the award. Delivery is FOB Origin, and the performance location is not specified. No budget amount or submission timeline is provided.
