The Russian Kamov OKB (design bureau) has also built a tactical UAV, the Kamov "Ka-137". Kamov has produced a number of different manned helicopter designs since the 1940s, focusing on the "coaxial" rotor configuration, with twin rotors spinning in opposite directions on the same shaft.

Kamov flew Russia's first unmanned helicopter, the Ka-37, in 1993, after developing the UAV with their own funds. The "Ka-37" looked like a scaled-down version of a Kamov manned helicopter, with the coaxial rotor configuration and a tailboom with fins. The Ka-37 was apparently sold in some numbers for agricultural applications, and led to an improved "Ka-37S" prototype in 1996 that featured a new engine.

The Ka-137 is a next-generation follow-on to the Ka-37, and has been substantially redesigned. The Ka-137 is an endearingly toylike machine, somewhat in a class with the Canadair CL-227, with a ball-shaped body, four landing legs, and a coaxial rotor system powered by a 49 kW (65 horsepower) piston engine. It can carry a TV imaging system, and can be operated using a truck-based support and control system. The Ka-137 is currently in use with Russian border guards and possibly Russian coast guard patrol boats.
