According to Wikipedia: "The Molniya-M (Meaning "lightning"), designation 8K78M, was a Russian (previously Soviet) carrier rocket derived from the R-7 Semyorka ICBM. Chiefly designed to correct design deficiencies in the third stage of the 8K78 booster, it was first launched in 1964 and had replaced its predecessor, Molniya, by the end of 1965. During 1967, the improved core stage and strap-ons from the Soyuz 11A57 were adopted and made standard on all R-7 based vehicles. It made 297 launches and experienced 21 failures, the last of which occurred on 21 June 2005 when a third stage malfunction prevented its payload, a Molniya-3K communications satellite from reaching orbit. The final flight of a Molniya-M was conducted on 30 September 2010. It will be replaced by the Soyuz-2/Fregat."
