Design and Development
Developed from the earlier Ka-15 to meet a 1958 Soviet Navy requirement for a heavy shipborne helicopter. The Ka-20 had a similar twin contra-rotating, three-blade rotors of the earlier Ka-15 design and was powered by two 670 kW turboshaft engines. The Ka-20 was built to demonstrate the feasibility of mounting the turbo-shaft engines above the cabin and it had no mission equipment or corrosion protection although it was fitted with a nose mounted radome.
The Ka-20 first became known outside of the Soviet Union at the 1961 Tushino Aviation Day display where a Ka-20 was demonstrated fitted with dummy missiles on the cabin sides. The design was developed as the Ka-25 anti-submarine helicopter.

Famous quotes containing the words design and/or development:
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
