Kamov Ka-20

From Wikipedia, the free encyclopedia

The Kamov Ka-20 (NATO reporting name Harp) was a Soviet twin-engine antisubmarine helicopter prototype. Twin turbine engines mounted above the fuselage drive two contra-rotating, three-blade rotors, typical of Kamov designs. For its anti-submarine mission, it utilizes a large radome fitted under the nose. In 1958, Kamov was awarded a contract for an anti-submarine helicopter. The resulting production Ka-25 bore only minor differences from the prototype Ka-20.

The Ka-20 first became known to the West from the 1961 Tushino Aviation Day display.
