Kamov is a Russian rotor-winged aircraft manufacturing company that was founded by Nikolai Il'yich Kamov who started building his first rotor-winged aircraft in 1929 together with N. K. Skrzhinskii. Up to the 1940s they created more autogyros including the A-7-3 the only armed one in the world that saw (limited) combat action. Since then the Kamov Design Bureau has specialised in compact helicopters of coaxial rotor design suitable for naval service and high-speed operations.
