The Kamov Ka-15 (NATO reporting name Hen[2]) was a Soviet two-seat utility helicopter with coaxial rotors, which first flew on 14 April 1952 at the hands of test pilot D. K.

In 1950, after evaluating the single-seat Kamov Ka-10, Soviet Naval Aviation developed a requirement for a larger and more capable two-seat helicopter with an enclosed cabin, but keeping the coaxial rotor layout of the Ka-10.

A 255 hp (190 kW) Ivchenko AI-14V radial engine was mounted behind the cockpit, and drove the three-bladed coaxial rotors.

[5][6][7] The Ka-15 entered service with Soviet Naval Aviation in about 1955, carrying out reconnaissance flights from icebreakers as well as liaison and training duties.

Roles included crop spraying, (with Kamov claiming that the Ka-15 was more efficient than the competing Mil Mi-1), patrolling power lines and pipelines, carrying airmail, and air ambulance.
