The AN / SQQ-89 is a modern submarine hunting system for surface ships. It is produced by Lockheed Martin .

description

With the SQQ-89, a comprehensive sensor fusion was carried out for the first time in the field of submarine hunting. It combines the data of the bow sonar , the tow sonar as well as the diving sonars and sonoboys of various anti- submarine helicopters in order to then provide a fire control solution for the weapon systems on board. Since the system is used on a large number of ships, there is a correspondingly large variety of variants.
