Kamov design bureau was established in late 1940s after successful demonstration of single engine ultra-light Ka-8 type and its improved derivate Ka-10, which was maiden flown on 30th of August 1949. Both were rather experimental types used for exploring of options how to utilize the helicopter and the latter one was adopted by the Soviet naval aviation into the regular service. Due to small dimensions and small footprint given by coaxial rotors Ka-10s were for the first time deployed on Soviet Navy vessels and gave to both Experimental design bureau OKB Kamov and Soviet Navy valuable expertise with maritime helicopter operation. In total four helicopters were test flown by the naval aviators with following order for ten serial ships. However, due to uncovered cockpit both types were really limited in its operational use and it just gave the background for further helicopter design for Kamov.
