This opportunity is for the acquisition of 6 units of a specific part (NSN 7R-5985-015461193-QE) that requires engineering source approval due to its flight-critical nature and limited technical data. Delivery is FOB Origin, and only previously approved sources have been solicited, as the part requires unique design capability and data rights held by the qualified source(s). New sources must submit detailed qualification information as outlined in the NAVSUP WSS Source Approval Brochure, and failure to provide all required data will result in the offer not being considered. The government intends to solicit and negotiate with only one source under FAR 6.302-1, but all responsible sources may submit proposals or capability statements. No specific budget amount or performance location is mentioned in the description.
