The Molniya-M (meaning "lightning"), GRAU designation 8K78M, was a Soviet Union (later Russian) launch vehicle derived from the R-7 Semyorka Intercontinental ballistic missile (ICBM).
The 8K78M was first launched in 1964; however, the existing stock of 8K78s had not been used up yet and they continued to fly until 1967. 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. There were no failures of 8K78Ms caused by the core and strap-ons, and after 1968, all failures were caused by the Blok L stage until 2005 when one of the last boosters flown suffered a Blok I engine failure.
The final flight of a Molniya-M lofted an Oko early warning satellite from Plesetsk on 30 September 2010 despite some apprehension that the launch vehicle, manufactured in 2005, had exceeded its storage life. It was replaced by the Soyuz-2/Fregat.
