This system is installed in MCM class ships. It consists of a straight tail magnetic sweep (M Mk 5A) combined with the A Mk 4(v) and/or A Mk 6(b) acoustic sweeps. Earlier versions of these components were all used by the US Navy WWII sweepers. The system can be configured several ways including diverting the magnetic cable and/or the acoustic devices by using components of the AN/SLQ-38 mechanical sweep gear.
The AN/SLQ-37 sweep system counters magnetic, passive acoustic and combination magnetic/passive acoustic mines by causing he mines to actuate on ship-like magnetic acoustic pulsed emissions emitted by the sweep.
