Russian military surveillance satellite. Planning began in mid-1967 for military systems to enter service through 1975. Reconnaissance, photo (film return type) satellite built by TsSKB for GRU, Russia. Launched 1968 - 1974. Used Zenit bus.

AKA: 11F691;4KM;Rotor. Status: Operational 1968. First Launch: 1968-10-31. Last Launch: 1974-07-25. Number: 61 . Gross mass: 6,300 kg (13,800 lb).

These included this improved model of Zenit-4 high resolution reconnaissance satellite, accepted into service in 1971. The photo system Ftor-6 replaced the Ftor-4 of the Zenit-4. The Zenit-4M was the first of the series equipped with a restartable engine which allowed adjustment of the orbit during the mission. High resolution, maneuverable; Typical orbital profile: inclination 65 degrees with altitude of 203-290 km; maneuvers to 178-312 km altitude. Also inclinations of 51.6 degrees; 72.8 degrees; 81.3 degrees. Designed duration: 13 days. Transmission frequencies observed in West: 19.150 PCM telemetry or 19.300 Morse-code.
