Laser Line Scan System (LLSS)
The Laser Line Scan System (LLSS) is an underwater towed body containing a solid state laser system used for minehunting along the ocean bottom. Currently under development, this rapidly-deployable system provides real-time two-dimensional images to operators in the aircraft to locate, classify, mark and record mine-like objects and underwater terrain features. The LLSS has an active, stabilized underwater vehicle. 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.
