packaged in a single towed body tethered to the ship through a cable providing power and data transmission, with the cable length variable via an electric winch. A hole in the ship extending from the sonar maintenance room (SMR) to the hull allows movement of the towed body in different configurations for maintenance, stowage at sea, and minehunting operations. The towed body can be configured for minehunting by either locking to the bottom of the ship's hull for shallow water operations, or by extending and retracting the tow cable to allow for variable depth sonar (VDS) operations. VDS operations are necessary in deep water due to refraction of the sonar from the various temperature layers present in the ocean; with the sonar positioned in the same thermal layer as the suspected mines the error induced by refraction is minimized. The detect and classify sonar subsystems are independently monitored and controlled by two operators at independent panels working together to find and characterize underwater objects as mine or non-mine like objects.
68:
The classify sonar has a lower range, but higher frequency and higher resolution to allow the classification of a target as mine-like or non mine-like. Once a target is located by the detect operator, they will hand off the position to the classify operator where they will analyze the characteristics

degrees of selectable coverage via electronic switching of sonar stave arrays circling the towed body. The newest AN/SQQ-32(V)4 upgrade contracted in 2011 includes a high frequency wide band (HFWB) modification that greatly improves shallow-water minehunting capabilities in high clutter environments.

The detect system is a low frequency, low resolution, high range sonar designed to provide a general location of possible mine-like objects. It provides much greater range than the classify sonar system but provides little resolution and detail of the objects it detects. It provides the operator 180

Raytheon and Thales Underwater Systems (formerly Thomson Marconi Sonar) for the United States Navy. It includes two separate active sonar systems to detect and classify mine-like objects on the surface, in the volume, or on the bottom of the sea. The sonar systems are

The AN/SQQ-32(V)4 system upgrade was designed and tested by Naval
