description Kamov Ka-27 Overview
The Kamov Ka-27 is a Soviet naval helicopter developed for operation from warships and introduced as a successor to the Ka-25. Its two coaxial, contra-rotating main rotors eliminate the need for a tail rotor, giving it a compact footprint suited to shipboard decks and hangars. The principal Ka-27PL variant performs anti-submarine warfare, while related versions have been adapted for search and rescue, transport, and airborne early warning duties.
help Kamov Ka-27 FAQ
Why does the Kamov Ka-27 not need a tail rotor?
The Ka-27 uses two coaxial, contra-rotating main rotors mounted on the same axis. Their opposing rotation cancels torque, removing the need for a separate tail rotor.
What helicopter did the Kamov Ka-27 replace?
The Ka-27 was developed as a successor to the Kamov Ka-25. Both were Soviet naval helicopters, but the Ka-27 provided a newer platform for ship-based anti-submarine and related missions.
Which Ka-27 variant is used for search and rescue?
The Ka-27PS is the search-and-rescue and transport-oriented variant of the family. The related Ka-29 is an armed transport version, while the Ka-31 is associated with airborne early-warning duties.
Why is the Ka-27's rotor layout useful on ships?
The coaxial rotor system gives the helicopter a compact footprint because it has no long tail rotor and tail boom. That is useful when operating from warship decks and storing the aircraft in confined hangars.
