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.

Derivatives

Meteor-3 weather observation satellite (Plesetsk, Aug. 15, 1991)|leftTwo rockets were derived from the Tsyklon: the Tsyklon-2 and Tsyklon-3, known respectively as the SL-11 and SL-14 by the US DoD. The two stage Tsyklon-2 was first launched August 6, 1969, from the Baikonur Cosmodrome in Kazakhstan, while the Tsyklon-3, which features a restartable third stage, first launched on June 24, 1977 from the Plesetsk Cosmodrome.

On December 27, 2000, A Tsyklon-3 failed in its attempt to carry six Russian satellites into orbit, plummeting to the earth. An electrical failure in the rocket's third stage was the suspected cause.
