Kosmos 136 was launched by a Vostok-2 rocket, serial number N15001-09,[6] flying from Site 41/1 at the Plesetsk Cosmodrome. The launch took place at 12:00:01 GMT on 19 December 1966,[7] 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.[1]
Kosmos 136 was operated in a low Earth orbit, at an epoch of 19 December 1966, it had a perigee of 188 kilometres (117 mi), an apogee of 280 kilometres (170 mi), an inclination of 64.6°, and an orbital period of 89.4 minutes.[3] 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.[2]
