Tsyklon

The Tsyklon (Циклон, "Cyclone", also known as Tsiklon), GRAU index 11K67, 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). Control system was designed at NPO "Electropribor" (Kharkiv, Ukraine). The last flown derivative, the Tsyklon-3 was retired in January 2009, however another derivative, the Tsyklon-4, is still under development.
