The crews of Ka-27 naval helicopters of the air force and air defense army of the Northern fleet worked in the Barents sea landing on the deck of a large anti-submarine ship "Severomorsk".

The large anti-submarine ship "Severomorsk" entered the training grounds of the Northern fleet on the eve of the day of naval aviation of the Russian Navy, which is celebrated at July 17.

During the flight shift, 4 crews of Ka-27 shipboard helicopters made 26 landings on the helipad of a large anti-submarine ship on the move.

In addition, helicopter pilots conducted overflights of the "Severomorsk" large antisubmarine ship (LAS) in order to check its radio equipment, air defense systems, communications and aviation control systems.

The flights followed the established route over the waters of the Northern fleet's sea ranges in the Barents sea. During training flights, helicopter crews also practiced tactical techniques using radar and sonar detection of submarines.
