The Tsyklon-3 also known as Tsiklon-3 GRAU index 11K68 was a Soviet and subsequently Ukrainian orbital carrier rocket. A derivative of the R-36 ICBM and a member of the Tsyklon family it made its maiden flight on 24 June 1977 and was retired on 30 January 2009. The Ukrainian-built Tsyklon rockets were retired in favour of future all-Russian carrier rockets such as the Angara and because they were fuelled by toxic hypergolic propellants.
