This opportunity is for the acquisition of two units of a specific part (NSN 7R-1270-016071330-CB) that requires engineering source approval from the design control activity due to its flight-critical nature. Only previously approved sources have been solicited, and new sources must submit detailed qualification information as outlined in the NAVSUP WSS Source Approval Brochure to be considered. Delivery is FOB Origin, and the part is subject to sole-source procurement under FAR 6.302-1, though all responsible sources may express interest. Proposals from non-approved sources must include all required technical data; failure to do so will result in disqualification. No specific budget amount or performance location is mentioned in the description.
