When was the first minesweeper built in the world?

The world's first batch of minesweepers were built by Russia in 1909, with a displacement of 150 tons and a speed of 12 knots. They were equipped with a small cutting minesweeper, a 75mm gun and two machine guns to deal with tethered mines (there were no induction mines at that time).

"Mine hunting" is a relatively new way of mine clearance. The biggest difference from mine clearance is that it has the ability to detect mines, find mines by various means, calibrate their precise positions and complete identification, and then divers or remote-controlled vehicles place explosives near the mines and detonate them one by one.

Therefore, the success of mine hunting operation has nothing to do with the detonation mode or timing/timing conditions of mines, as long as the mines detected by mine hunting ships can be hunted; However, depending on mine-sweeping operations to clean the waterway may be affected by the types of mines. Even if it is cleaned repeatedly, there is no guarantee that there will be mines that have escaped the net.

In order to find small mines and complete accurate positioning, mine hunting ships have sophisticated navigation and positioning systems, high-resolution mine detectors and other equipment.

In addition, another major technical feature of the mine-hunting boat is the well-equipped remote-controlled mine-hunting car, which is equipped with high-precision sonar, underwater searchlights and television cameras to find mines and complete identification operations. In addition, it can also carry anti-personnel mine explosives, put them near mines, and then detonate them remotely to destroy mines.

The new generation of mines often adopt technologies such as intelligence, timing, timing and sensitivity adjustment, which will hinder mine-clearing operations, but will not affect the success or failure of mine-clearing operations. As long as it is discovered, it will be destroyed.

In addition, mine hunting ships usually use remote control vehicles for long-distance mine clearance, and the ship itself can detonate mines hundreds of meters away, with high safety; The traditional minesweeper needs to drag the minesweeper in person to sail in the minefield. Whether accidentally touching or detonating a mine at close range, the probability of affecting itself is much greater.

Because the mine hunting ship has all kinds of accurate submarine landform detection and positioning equipment, it can also support the work of searching for sediments, submarine exploration and laying submarine cables. However, the biggest disadvantage of mine hunting is that each mine can only handle blasting separately, so its mine-sweeping operation speed is slower than mine-sweeping.
