TheTsyklon-2(Ukrainian:Циклон-2,lit.'Cyclone-2'), also known asTsiklon-2andTsyklon-M(known asSL-11by the United StatesDoD),GRAUindex 11K69, was aSoviet,laterUkrainian,orbitalcarrier rocketused from the 1960s to the late 2000s. The rocket had 106 launches, one suborbital and 105 orbital, with only one failure and 92 consecutive successful launches, from 27 December 1973 with the launch of Kosmos 626 to 25 June 2006 with the final flight of the Tsyklon-2, which makes this launcher most reliable within rocket launched more than 100 times.

History[edit]

A derivative of theR-36ICBM,and a member of theTsyklonfamily, the Tsyklon-2 made its maiden flight on 6 August 1969, and conducted 106 flights, the last one occurring on 24 June 2006. It was the most reliable Soviet/Russian carrier rocket ever used, and launched more than 100 times having failed only once, and the second most reliable carrier rocket overall, behind theAtlas IIthat was launched only 63 times.[2]Along with otherR-36family memberTsyklon-3,the Tsyklon-2 was retired in favor of new-generation and all-Russian carrier rockets, such as theAngaraand Soyuz-2.

Description[edit]

Like the Tsyklon-3, the Tsyklon-2 was derived from the R-36ScarpICBM. However, it did not have a third stage, like the Tsyklon-3 did, also it was slightly shorter and had a lower weight mass when fueled.[3]
