The Kamov Ka-27 (NATO reporting name 'Helix') is a military helicopter 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.

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 helicopters it has coaxial rotors, removing the need for a tail rotor. Ka-32 variants, e.g. the Klimov-powered Ka-32A11BC, have been certified for commercial operations throughout the world, notably in Canada and Europe.

A Russian Navy Ka-27 helicopter from the Russian Udaloy-class destroyer RS Severomorsk (DDG 619) conducted interoperability deck landing training on board USS Mount Whitney on 22 July 2010.

Ka-32A11BC multipurpose helicopters have been successfully operated in Portugal for over five years. In 2006, KAMOV JSC won the tender for the supply of Ka-32A11BC firefighting helicopters, to replace Aérospatiale SA-330 Pumas, which have very high operating costs.

The Ka-32A11BC features a high power-to-weight ratio and ease of handling, owing to its coaxial rotor design. The rotors' diameters are not restricted by the presence of a tail rotor and associated tail boom; this facilitates maneuvering near obstacles and helps assure exceptional accuracy when hovering in heavy smoke and dust conditions. The Ka-32A11BC may be equipped with the Bambi Bucket suspended fire-fighting system of up to five tons capacity. The service life has been extended to up to 32 000 flight hours.
