Charges are usually used against influence and/or bottom mines but for moored mines
the 'fish' can carry a chain cutting charge such as the Rheinmetall DM59, 69, 119 and 129 used in Pap, Pluto and Pinguin or SEI CM 102 to cut the mine's mooring allowing it to be destroyed by gunfire on the surface.
Moored mines are buoyant cases held in place by anchors.
Moored mines cut loose by mechanical sweeping must then be neutralized (as by gunfire or explosive charges) or rendered safe for subsequent analysis.
In 1991, it took the US-led allies 51 days, from March 1 to April 20, to clear 1,157 moored mines
laid by the Iraqis off Kuwait--three of which hit two US warships.
The US Navy's AWS-2 Ramics (Rapid Area Mine Clearance System) is being developed to arm the Sikorsky MH-60S, tasked with protecting surface vessels against floating and near-surface moored mines
. These will first have been detected by other sensors, and then reacquired by the Northrop Grumman AWS-1 Almds (Airborne Laser Mine-Detection System) on the MH-60S.
The RMS missions are to detect, classify locate and identify bottom and moored mines
in shallow and deep waters.
During the late 1980s, Iran relied exclusively on vintage design moored mines
acquired from North Korea but based on Soviet designs.
A critical design review is planned for the AN/AQS-20 Airborne Mine Hunting Sonar, a helicopter-towed, high-speed reconnaissance mine hunter that can detect, locate and classify unburied, bottom, close-tethered and moored mines
in both shallow and deep water.
The MH-53E tows MK-103 mechanical minesweeping gear designed to remove moored mines, an MK-105 minesweeping sled and a side-scan sonar ASQ-14 that is used in murky, swallow coastal waters for detecting, locating and identifying mines.
It is designed to explode unburied or moored mines that may be located in areas deemed too difficult and therefore, unsafe to deal with by any other methods.
