The U.S. Navy is testing a new unmanned mine-detection system that uses flying metal detectors to search for underwater mines. The system, called the Mine Hunting Unmanned Surface Vessel (MHUSV), is designed to detect and classify mines using a variety of sensors, including metal detectors, side-scan sonar, and magnetometers.

The MHUSV is a small, autonomous boat that can be operated remotely from a distance of up to several kilometers. The boat is equipped with a variety of sensors that are used to detect and classify mines. The metal detectors are used to detect the presence of metal objects, while the side-scan sonar and magnetometers are used to create images of the underwater environment.

The MHUSV is also equipped with a variety of countermeasures that can be used to neutralize mines. These countermeasures include a water jet that can be used to disrupt the fuzing mechanism of a mine, and a shaped charge that can be used to destroy a mine.

The MHUSV is currently undergoing testing by the Navy. The system is expected to be deployed in the fleet in the near future.

Here are some additional details about the MHUSV:

* The MHUSV is approximately 11 meters long and 3 meters wide.

* The MHUSV weighs approximately 4,500 kilograms.

* The MHUSV has a range of approximately 100 kilometers.

* The MHUSV can operate in water depths of up to 100 meters.

* The MHUSV is equipped with a variety of sensors, including metal detectors, side-scan sonar, and magnetometers.

* The MHUSV is also equipped with a variety of countermeasures, including a water jet and a shaped charge.

The MHUSV is a promising new technology that has the potential to significantly improve the Navy's ability to detect and neutralize mines. The system is expected to be deployed in the fleet in the near future, and it will play a vital role in keeping the Navy's ships and sailors safe from mines.
