MOSCOW, January 24. /TASS/. The crews of Caspian Flotilla ships employed the latest sonars to detect hostile underwater drones in the areas of the ships’ naval bases, the press office of Russia’s Southern Military District reported on Friday.

"The Flotilla’s minesweepers dropped robotized deep-water submersibles, after which the ships’ crews and sonar-operating teams were given the command for their search and detection," the press office said in a statement.

The sailors employed the sonar systems to search for underwater objects and determine their characteristics at ranges of over 200 meters with the minimal margin error in coordinates.

The sonar equipment allows the Flotilla’s forces to get comprehensive information on the underwater situation in the Caspian Sea and in the areas of the ships’ naval bases.
