AN/AQS-20 Minehunting System
The AN/AQS-20 mine hunting sonar systems will be employed for deeper mine threats. The "Q-20", as it is commonly called, is an underwater towed body containing a high resolution, side-looking, multibeam sonar system used for minehunting along the ocean bottom. This rapidly-deployable system provides real-time sonar images to operators in the aircraft to locate, classify, mark and record mine-like objects and underwater terrain features. The AQS-20 has an active, stabilized underwater vehicle, equipped with advanced multiple-beam side-looking sonar. The MH-53E Sea Dragon helicopter tows the underwater body by a small-diameter electromechanical cable. On board the helicopter, an operator can view the underwater image and identify objects on a video monitor while recording the data on S-VHS digital tapes for post mission analysis. Operators actually fly the device underwater, actively controlling the depth or altitude of the device in the water column. Once located, the exact coordinates of mine-like objects can be used by Explosive Ordinance Disposal (EOD) personnel to reacquire and neutralize the mine.
