The first Mi-26 Halo prototype flew in December 1977 and was first displayed at the Paris Air Show in 1981. In 1982, Russian squadrons received their first Halos, which were not fully operational until 1983. In 1986, India was the first country to purchase a Halo. Since then Halos have been sold to nearly twenty countries.
The production Ka-25BSh Hormone-A was of near identical size and appearance, but was fitted with operational equipment and uprated GTD-3F turboshaft engines
With more than double the power of the Ka-25 Hormone, the Ka-27 is a considerably heavier helicopter with a larger fuselage, but nevertheless offers increased performance with much-improved avionics and more modern flight-control system.
The main mission of the Ka-31 is a long-range detection airborne and naval threats. This helicopter can track targets over much larger horizon than ship’s radars. It makes it an important completion for naval task force, whose ships are too small to operate carrier-borne early warning aircraft.
