A derivative of the R-36 ICBM, and a member of the Tsyklon family, it made its maiden flight on 6 August 1969, and after 106 launches, made its final flight on 24 June 2006. At the time of retirement, it was the most reliable active carrier rocket in the world, having failed only once. It is the second most reliable carrier rocket overall, behind the Atlas II. It was retired in favour of future modern and all-Russian carrier rockets, such as the Angara.

Due to the covert nature of its missions, it is hard to be certain that it has been retired, however it has been reported that only one Tsyklon launch remains [http://armstass.su/?page=article&aid=49743&cid=25 APMC - Космические войска обеспечили реальность сроков сдачи в эксплуатацию перспективного РКК "Ангара"] (Russian)] , and that is a Tsyklon-3.
