OVERVIEW: The Ka-27 (NATO reporting name 'Helix') is a developed for the Soviet Navy, and currently in service in various countries including Russia, Ukraine, Vietnam, People's Republic of China, Republic of Korea (South Korea), and India. Variants include the Ka-29 assault transport, the Ka-28 downgraded export version, and the Ka-32 for civilian use.

DETAILS: The helicopter was developed for ferrying and anti-submarine warfare. Design work began in 1969 and the first prototype flew in 1973. It was intended to replace the decade-old Kamov Ka-25, and is similar in appearance to its predecessor due to the requirements of fitting in the same hangar space. Like other Kamov military it has coaxial rotors, removing the need for a .
