The Government requires 5 each of NSN 7R-5865-017175454-E8, reference 309K658G06, delivered FOB origin. The item is flight critical and/or lacks adequate technical data for full and open competition, so Government source approval is required before award and only previously approved sources have been solicited. New sources must submit the NAVSUP WSS Source Approval Brochure information with their offer, or document prior submission of the required data; offers missing required data will not be considered. The Government intends to solicit and negotiate with only one source under FAR 6.302-1, though responsible sources may identify interest and capability or submit proposals/quotations/capability statements; this is not a request for competitive proposals. No drawings are available for this request.
