This opportunity is for the acquisition of 8 units of a specific part (NSN 7R-5821-014178763-FX) that requires engineering source approval due to its flight-critical nature. Only previously approved sources have been solicited, and the time required to approve a new source is too long to delay the award. If you are not an approved source, you must submit detailed technical data as outlined in the NAVSUP WSS Source Approval Brochure with your proposal. The government intends to solicit and negotiate with only one source under FAR 6.302-1, but all responsible sources may submit proposals. Delivery is FOB Origin, and performance location is not specified.
