This opportunity is for a single unit of NSN 7R-1730-014618330-QE, with delivery on an FOB origin basis. The item is flight-critical and lacks adequate technical data, so government source approval is required prior to award; only previously approved sources have been solicited. Any new source must submit all required technical data per the NAVSUP WSS Source Approval Brochure, or its offer will not be considered. The Government intends to award to a single source under FAR 6.302-1, but all responsible sources may express interest and submit capability statements. Award will only be made to offerors, products, or manufacturers that meet qualification requirements at the time of award.
