max kamov 27 helix russian - KAMOV 27 HELIX A RUSSIAN HELICOPTER by De Espona

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.
