The Kamov Ka-27 (NATO reporting name 'Helix') is a military helicopter developed for the Soviet Navy and currently in service in Russia, Ukraine, Vietnam, South Korea, China and India. The Ka-28 is a downgraded export version, while the Ka-32 is designed for civilian use.

Design and development

The helicopter was developed for ferrying and anti-submarine warfare. Design work began in 1970 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 helicopters it has a co-axial rotor, removing the need for a tail rotor.
