This opportunity is for the acquisition of 3 units of a specific part (NSN 7R-1680-016176844-QF) with delivery FOB Origin. The part requires engineering source approval, as it is flight critical and only previously approved sources have been solicited. New sources must submit detailed technical data per 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. No budget amount or performance location is specified.
