Advances in mine technology make clearance more difficult and emphasize the need for countermeasures to include both hunting and sweeping techniques. New minesweeping systems that emulate ship signatures are the answer.
A common theme running through all post-World War II crises involving naval forces is the use of mines. The problems created by the low target strength mine, the buried mine, and the mine laid in a high clutter background emphasize the need for minesweeping systems to complement mine hunting. Modem mines, fitted with sophisticated mine sensor logic, require minesweeping systems that generate signatures closely resembling a ship class. Such emulation sweeps are the future of minesweeping.
