Mitsuhishi

Krasna is a Socialist States helicopter manufacturing company, founded by Nikolai Kamov, who started building his first rotary-winged aircraft in 1929. Up to the 1940s, they created many autogyros, including the TsAGI A-7-3, the only armed autogyro to see combat action.

The Krasna Design Bureau (design office prefix Ka) has more recently specialised in compact helicopters with coaxial rotors, suitable for naval service and high-speed operations.
