Zenit-4M
Credit: © Mark Wade
Russian military surveillance satellite. 61 launches, 1968.10.31 (Cosmos 251) to 1974.07.25 (Cosmos 667). Planning began in mid-1967 for military systems to enter service through 1975.

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.

AKA: 11F691; Rotor.
Gross mass: 6,300 kg (13,800 lb).
First Launch: 1968.10.31.
Last Launch: 1974.07.25.
Number: 61 .

  • Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...

Associated Launch Vehicles
  • Soyuz Russian orbital launch vehicle. The world's first ICBM became the most often used and most reliable launch vehicle in history. The original core+four strap-on booster missile had a small third stage added to produce the Vostok launch vehicle, with a payload of 5 metric tons. Addition of a larger third stage produced the Voskhod/Soyuz vehicle, with a payload over 6 metric tons. Using this with a fourth stage, the resulting Molniya booster placed communications satellites and early lunar and planetary probes in higher energy trajectories. By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers entered service in the new millenium, and a new launch pad at Kourou was to be inaugurated in 2009. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...
  • Voskhod 11A57 Russian orbital launch vehicle. The 11A57 took the large third stage originally developed for the 8K78 interplanetary probe projects and applied it to increasing R-7 low earth orbit performance. It was primarily designed to launch the Zenit-4 reconnaisance satellite, but was also used for the Voskhod manned flights and later for a variety of other Zenit series versions. More...

Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur. More...
  • Plesetsk Plesetsk was the Soviet Union's northern cosmodrome, used for polar orbit launches of mainly military satellites, and was at one time the busiest launch centre in the world. The collapse of the Soviet Union put the main launch site of Baikonur in Kazakh territory. It now seems that once the Proton rocket is retired, Baikonur will be abandoned and Plesetsk will be Russia's primary launch centre. Upgrades to existing launch facilities will allow advanced versions of the Soyuz rocket and the new Angara launch vehicle to be launched from Plesetsk. Plesetsk's major drawback was the lower net payload in geosynchronous orbit from a northern latitude launch site. However Russia is planning to remove the disadvantage by looping geosynchronous satellites around the moon, using lunar gravity to make the necessary orbital plane change. More...
