The Russian Navy has begun flight tests and warfare trials of its modified Kamov Ka-27M anti-submarine helicopter from large destroyers. “The modernized Ka-27M (NATO codename Helix) is completing deck landings on a ship as well as trials of its main systems," fleet's spokesman, Captain Vadim Serga said on Monday. The Ka-27M has already undertaken deck landing trials on a stationary destroyer at a berth on the Kola Peninsula, he added. "The new machine has not only had modern avionics systems installed, but also updated special missions systems," he said. In addition, it has a new radar giving 360 degree coverage and a greater search radius and simultaneous tracking of dozens of targets. "The modernized Ka-27M has also had its service life extended by another 10 to 15 years," Serga added. It is fitted with a dipping sonar system as well as sonobuoys, and can be armed with depth charges and torpedos.
