The Tsyklon was a Soviet/Ukrainian-designed expendable launch system, primarily used to put Cosmos satellites into low Earth orbit. It is based on the R-36 intercontinental ballistic missile designed by Mikhail Yangel and made eight launches, with seven successes, and one failure. All of its launches were conducted from LC-90 at the Baikonur Cosmodrome. It is sometimes designated Tsyklon-2A, not to be confused with the later Tsyklon-2 rocket. It was introduced in 1967 and was derived from the R-36 ICBM (NATO designation of SS-9, Scarp). It was retired in 1969.
It made its maiden flight on 27 October 1967.
Tsyklon was designed by the Yuzhnoe Design Bureau and manufactured by Yuzhmash (both in Dnipropetrovsk, Ukraine). A derivative, the Tsyklon-3 is still in service as of February 2008.
