FactoryRegistry lists 1,683 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced sonar search, detection, tracking, and communication systems and equipment guidance, including ASM (sonar telephone, depth finding, hydrophones mapping, sonobuoys, etc.), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
