To track the American nuclear submarine of the Virginia type, the sailors of the frigate Marshal Shaposhnikov used the sonar station "Polinom". The foreign submarine was identified by the sonar track and felt the impact of the anti-submarine system on the hull.
According to TASS, during the incident on February 12, a US nuclear submarine approached the Russian coast closer than 12 nautical miles, thereby violating the state border in the Kuril Islands area. The purpose of the submarine could be to spy on the Pacific Fleet ships conducting exercises.
Having discovered the submarine, the frigate Marshal Shaposhnikov activated the warning depth bombing installations and the sonar station "Polinom". By the way, the underwater gas with a circular view allows you to detect torpedoes, underwater mines and submarines at a maximum range of up to 50 kilometers.
"The ship's acoustics did not release someone else's boat from the sonar support and continuously acted on it, studying its evasion tactics until it broke away," the news agency reports.
Military experts note that the submarine should have been the first to hear the Russian anti-submarine ship, but allowed its approach and did not immediately go to evade it. Only after detection, the submarine used a motion simulator to escape from Russian territorial waters.
It should be noted that nuclear submarines of the Virginia type, with a displacement of 7800 tons, are considered the lowest-noise submarines in the United States. The speed is up to 32 knots or 59 kilometers per hour. The crew is 132 people. The submarine's arsenal includes 12 vertical launchers or two revolver-type launchers for Tomahawk cruise missiles, as well as four vehicles for Harpoon anti-ship missiles or Mk 48 torpedoes.
