Ukrainian earth resources radar satellite. 9 launches, 1986.07.28 (Cosmos 1766) to 2004.12.24 (Sich-1M). Third generation Soviet oceanographic research satellite, equipped with a side-looking radar, radiometer, and multi-spectral scanner.

Oceanographic research satellite, developed by KB-3 at NPO Yuzhnoye in the Ukraine, Vladimir Iosifovich Dranvoskiy, Chief Designer. The Okean oceanographic research satellite, later called Sich-1 by the Ukrainians, weighed 1950 kg, of which 505 kg was scientific instruments. Development was authorized on 5 May 1977 as one of the third generation of Soviet space systems. It was equipped with:

  • SUOS pointing, orientation, and stabilization system including:
    • Korall-A6 radio-command command-programming-trajectory system
    • BR-91Ts radiotelemetry system
    • STR thermoregulation system

  • Tsiklon The R-36 ICBM was the largest ever built and the bogeyman of the Pentagon throughout the Cold War. Dubbed the 'city buster', the 308 silos built were constantly held up by the US Air Force as an awesome threat that justified a new round of American missile or anti-missile systems. On the other hand, the Americans were never motivated to build and deploy corresponding numbers of their equivalent, the liquid propellant Titan 2. Derivatives of the R-36 included the R-36-O orbital bombing system, the Tsiklon-2 and -3 medium orbital launch vehicles, and the replacement R-36M missiles. With the collapse of the Soviet Union, the design and manufacturing facility ended up in independent Ukraine. Accordingly the missile was finally retired in the 1990's, conveniently in accordance with arms reduction agreements with the Americans. More...

  • Tsiklon-3 Ukrainian orbital launch vehicle. The Tsyklon 3 was developed in 1970-1977 as a part of a program to reduce the number of Soviet booster types. The first two stages were derived from the 8K68 version of the R-36 ICBM, while the restartable third stage was derived from that of the R-36-O. Compared to the Tsyklon 2, the launch vehicle increased payload to 4 metric tons, provided for completely automated launch operations, and had increased orbital injection accuracy. More...

Associated Launch Sites
  • 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...
  • Plesetsk LC32/1 Tsiklon launch complex. Construction of this highly-automated launch complex for the Tsiklon-3 launch vehicle started in 1970. The complex was designed by the Transmash Design bureau led by Chief Designer V N Solovyev. The complex consisted of two pads. The vehicle was assembled and integrated with its payload in the assembly building. It was then delivered to the launch pad by railway in a horizontal position. A launch pad erector placed the rocket into vertical position. No service tower was needed for the storable-propellant booster. More...
