MK-103 Minesweeping System
The MK-103 Mechanical Minesweeping System is a diverted wire sweep used for clearing moored mines. The sweep consists of a tow wire, one to four sweep wires, a lead float, a depressor (to maintain sweep depth), otters (to divert sweep wires to port and/or starboard), Mk17 Mod 1 cutters, and various connectors and floats. The submerged sweep wires are towed at a preselected depth, flair out and guide mooring cables or chains into the jaws of the cutters. An explosive charge then drives a chisel through the mooring cable allowing the bouyant mine to rise. The free mines float to the surface where they are neutralized by trained personnel. The Mk-103 can be transferred from helicopter to helicopter, ship to helicopter, and vice versa.
