This opportunity is for the acquisition of 3 units of a specific part (NSN 7R-5845-016590089-CB) that requires engineering source approval from the government due to its flight-critical nature and limited technical data. Delivery is FOB origin, and only previously approved sources have been solicited, as the government intends to negotiate with a single source under FAR 6.302-1. New sources must submit qualification data as detailed in the NAVSUP WSS Source Approval Brochure, but award cannot be delayed for approval processing. All responsible sources may submit capability statements or proposals for consideration, with proposals due within 45 days of the synopsis publication. No specific budget amount or performance location is specified in the description.
