This opportunity is for the procurement of 6 units of a flight-critical part (NSN 0Q-2990-014638955-CL) with delivery FOB Origin. The government lacks the technical data to purchase or repair this part from additional sources and has determined it is uneconomical to acquire the data or reverse engineer the item. Only previously approved sources have been solicited, and new sources must submit detailed information per the NAVSUP WSS Source Approval Brochure to be considered. The government intends to solicit and negotiate with only one source under FAR 6.302-1, but all responsible parties may submit capability statements. Proposals will be considered if received within 45 days of this synopsis's publication.
