a special device on minesweepers and helicopters that is used for the detection and destruction of mines (see). There are ship, motorboat, airplane, and coastal sweeps; sweeps adapted for river use are called river sweeps. Depending on their design and how they are used, sweeps are classified as single-ship, double-ship, surface, deep-water and bottom sweeps.
Sweeps are subdivided into two categories, depending on whether they make contact with the mines. Contact sweeps are intended for the destruction of moored contact mines; they may tow or mark the mines or cut the mooring lines. Noncontact or influence sweeps are designed to destroy bottom mines. They generate a magnetic, electromagnetic, or hydrodynamic field when moved, thus simulating the motion of a ship and actuating the mine fuzes.
What does it mean when you dream about sweeping?
