The Kamov Ka-137 previously designated MBVK-137 is an unmanned multipurpose helicopter designed for many roles including reconnaissance patrol police and ecology emergency and data transmitting. Three versions of the Ka-137 were made — one ship-based one automobile-based and another carried by the Ka-32 helicopter. The aircraft uses a piston engine driving a coaxial-rotor system and features a tailess sphere-shaped fuselage with four-leg leaf-spring landing gear.
