Special US sonar reveals all Russian and Chinese submarines

According to the US Defense Advanced Research Projects Agency (DARPA), this special type of sonar is called Scalable (MS3). This system is designed to be able to search, detect, filter out passive threats, locate and track targets without human control.

More specifically, MS3 can also accurately distinguish different types of enemy submarines. MS3 enables anti-submarine warfare (ASW) and underwater operations in both active and passive search modes, torpedo detection and warning, and collision avoidance with small objects.

Data from the MS3 multi-function sonar can be transmitted to a command and control center, providing a comprehensive view of part of its anti-submarine warfare mission.

Currently, MS3 is being integrated into the Sea Hunter unmanned ship - a ship with very high stealth capabilities, helping the ship operate effectively in shallow seas, Gulfs or areas with many coral reefs, which are often ideal shelters for small diesel-electric submarines.

Not only that, this type of sonar can also easily detect nuclear-powered submarines in deep sea areas. This vehicle can return to port after 3 months of continuous operation at sea to refuel and repair necessary parts.

To control and monitor the Sea Hunter, a ship command station allows the operator to monitor all activities of the unmanned vessel from multiple channels.

DARPA further revealed that this submarine hunter is not equipped with weapons, it is only designed to find and track stealth submarines and eliminate them as a threat.

However, despite the impressive claims about the special American MS3 sonar, Russia claims to have a way to counter this system once it is put into service by the US.

According to the statement of the head of the Defense Research and Development Bureau SPbGMTU Igor Kozhemyakin, the underwater robot "Black Sea Shadow" has just been successfully tested by the manufacturer and the Russian Navy in the Baltic Sea.

“We have successfully tested the ‘Black Sea Shadow’ in the Baltic Sea. The new hybrid device is capable of overcoming ocean currents thanks to its propellers. At the same time, tracking this submersible is almost impossible. It moves almost without making any noise,” said Kozhemyakin.

According to him, in the tests, the robot worked both in closed water areas as well as in the open sea in areas with ocean currents. The length of the device is 3m, diameter is 31cm, weight is 150kg, maximum speed is 2 miles/h, payload is 15kg.

This type of underwater robot can create signals similar to the activities of a submarine to deceive the enemy. In the mission of deceiving the enemy, the "acoustic decoy" of this robot can create sound waves similar to the propellers of Russian surface ships and submarines to "deceive" the probes on torpedoes and sonar of enemy submarines.

Once submerged and activated, the system will automatically transform into a false target that attracts torpedoes and enemy submarines. According to plans, the Russian Pacific Fleet will be the first unit to be equipped with this special weapon.

In its mission to deceive the enemy, the robot has an operating time of 5 minutes, just enough time for Russian submarines and warships to dodge a torpedo or escape from an enemy submarine.

With this new generation of robots, the Russian Navy's combat capabilities have increased significantly while enemies are disoriented when trying to locate and launch an attack on Russian submarines.

The special thing about this Russian underground robot being tested is that in addition to creating fake signals to deceive the enemy, when needed, this robot can perform reconnaissance missions with much longer operating time without making any noise.

According to Russian military expert Mikhail Barabanov, when put into operation, this robot, together with Paket-NK, will create a perfect shield for Russian submarines and warships against enemy search and destroy efforts.
