A Zenit-2 spacecraft, Kosmos 136 was the forty-fourth of eighty-one such satellites to be launched and had a mass of 4730 kg. In addition to its reconnaissance mission, the satellite was also used for scientific research.

Kosmos 136 was launched by a Vostok-2 rocket, serial number N15001-09, flying from Site 41/1 at the Plesetsk Cosmodrome. The launch took place at 12:00:01 GMT on 19 December 1966, and following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1966-115A and the Satellite Catalog Number 02624.

Kosmos 136 was operated in a low Earth orbit, at an epoch of 19 December 1966, it had a perigee of 188 km, an apogee of 280 km, an inclination of 64.6°, and an orbital period of 89.4 minutes. After eight days in orbit, Kosmos 136 was deorbited, with its return capsule descending under parachute, landing at 06:00 GMT on 27 December 1966, and recovered by Soviet force.
