This opportunity is for the acquisition of 7 units of a specific part (NSN 6K-8145-011428789-VH) with delivery FOB origin. The part requires engineering source approval from the design control activity, as it is flight critical and only previously approved sources have been solicited. Any new source must qualify through Government-approved procedures, and the time required for approval typically prevents delaying the award. If you are not an approved source, you must submit detailed technical data as outlined in the NAVSUP WSS Source Approval Information Brochures with your proposal. Offers lacking the required source approval data will not be considered for award.
