This requirement is for 55 each of NSN 7R-1680-015337193-V2, TDP version 001, delivered FOB origin. The part requires engineering source approval by the design control activity and is flight critical and/or lacks technical data sufficient for full and open competition, so only previously approved sources have been solicited. New sources must qualify under the design control activity’s approved procedures and submit the information required by the applicable NAVSUP WSS Source Approval Information Brochure with their offer. Offers that fail to provide all required source-approval data, or documentation of prior complete submission, will not be considered for award. If a source approval request cannot be processed in time or approval requirements prevent timely fulfillment, award may proceed based on Fleet support needs.
