This opportunity is for the acquisition of 27 units of a specific part (NSN 7R-1270-015469311-QF) with delivery FOB Origin. The part requires engineering source approval from the design control activity, as it is flight critical and only previously approved sources have been solicited. New sources must submit detailed qualification information as outlined in the NAVSUP WSS Source Approval Brochure, and proposals failing to provide this data will not be considered. The government intends to solicit and negotiate with only one source under FAR 6.302-1, but all responsible sources may submit proposals. Proposals will be considered if received within 45 days of the synopsis publication.
