The Navy's Avenger class Mine Countermeasure Ship (MCM) Guardian (MCM 5) was cut up and removed from the coral reefs near the Philippine islands after running aground last January.

I was part of the commissioning crew of Avenger (MCM-1) and served from 1987 to 1990.

can you please tell us more about it? like... do we have a very few minesweeper ships? is it very important? how effective is it? or any interesting facts. I don't know much about this minesweeper ship.

From the US Navy Fact File

In the early 1980s, the U.S. Navy began development of a new mine countermeasures (MCM) force, which included two new classes of ships and minesweeping helicopters. The vital importance of a state-of-the-art mine countermeasures force was strongly underscored in the Persian Gulf during the eight years of the Iran-Iraq war, and in Operations Desert Shield and Desert Storm in 1990 and 1991 when the Avenger (MCM 1) and Guardian (MCM 5) ships conducted MCM operations.

Avenger class ships are designed as mine sweepers/hunter-killers capable of finding, classifying and destroying moored and bottom mines. The last three MCM ships were purchased in 1990, bringing the total to 14 fully deployable, oceangoing Avenger class ships.

These ships use sonar and video systems, cable cutters and a mine detonating device that can be released and detonated by remote control. They are also capable of conventional sweeping measures. The ships are of fiberglass sheathed, wooden hull construction.

MCM's are capable of cruising any ocean. There are smaller class ships, more like "boats", the MSC which is only for coastal waters and rivers.

In 1986 I volunteered to join the Avenger which was under construction in WI. I already had a background of 4 years as a mine warfare inspector in Charleston, SC so I was a shoe-in for the job. My time was up to go to shore duty 6 months prior to the Avenger heading for the Gulf War.
 
cable cutter??? what for? what's a cable doing in ocean? is it for prop-fouling?
 
There are a few short Youtube videos on MCM's. Normally I don't recommend wiki, but this is ok. I have a large picture like shown on my wall. The explosion is the second one set off during shock trials in Key West, FL. We had dead fish on the deck.

Many 3rd world countries use the old style mines such as a contact mine. It floats so a long chain is attached to a large concrete block on the bottom of the ocean. The mine is placed just below the surface to make it hard to see. If your ship hits it and it blows up, you're screwed.

MCM's have a remote controlled submarine that has a camera, and two claws (cutters). When the sub goes to the chain, it snips the chain, the mine comes to the surface. Sharpshooters then blow it up.

There are bottom mines that wait until a ship sails over it and it detonates. The sub also carries a small 'bomb' that can be placed next to the mine, back away, and the charge is detonated from the ship.

There is also smart mines that wait on the bottom for up to a year, waiting for a preprogrammed signal that may only detect enemy ships or submarines, but not ships or subs from the country that placed it there. It turns itself on and goes after the target (like a torpedo). Only a few countries can afford those.

All the equipment on the stern is towed behind the ship at preset depths and can blow up numerous mines at a time.

MCM's are built of wood, fiberglass and stainless steel (all non-magnetic). Even the engines are low-magnetic.

I am only giving everyone the non-classified version. MCM's also have a 3-D side-scan sonar that lowers through the bottom of the ship via a long cable, to "see" mines, etc. The large cable reel can be seen just below the bridge.

These ships were needed because the last ones (MSO's) were built in the 1950's and used up until a number of MCM's were built.
