Russian vessels practise anti-submarine warfare in seas off Asia.

Warships from the Russian Pacific Fleet are conducting anti-submarine exercises in waters off the country’s far eastern coast. The exercises involve three corvette warships tasked with locating and destroying a mock enemy submarine with the assistance of helicopters in the Sea of Japan. The fleet also engaged in other anti-aircraft and anti-submarine defense drills. The final stage of the exercises will involve “ship-based counter-sabotage support units with practical counter-sabotage grenade-launching.” The exercises are the second in less than three weeks that the Russia navy has performed in the same waters. In late March, Russian missile boats fired cruise missiles at a mock target in the Sea of Japan.
