Article Number: 11F691. Code Name: Rotor. Class: Surveillance. Type: Military. Nation: USSR. Manufacturer: TsKB.

Planning began in mid-1967 for military systems to enter service through 1975. These included this improved model of Zenit-4 high resolution reconnaisance 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.


Specification

Total Mass: 6,300 kg.


Zenit-4M Chronology


18 June 1964 USSR five-year military space plan issued.

Ministry of Defence Decree 'On military space programs for 1964-69, including the R spaceplane' was issued. The decree was issued by Defence Ministry Marshal Rodiono Yakovlevich Malinovksiy. Included in this plan were new versions of the automatic Zenit, More-1 (US series) spacecraft, the Spiral spaceplane, the Soyuz-R manned combat spacecraft, and others. Chelomei's Raketoplan spaceplane was cancelled.
