Many Soviet children used to dream about becoming cosmonauts. Or to be somehow related to cosmonautics. But today it's seldom like this. Nevertheless different new projects are still being worked on and people are simply unaware of them. Here is one of such
projects. RD-861K rocket engine has been developed based on RD-861 which was used for early modifications of the carrier rocket "Cyclone". Fire tests have been conducted since 2007. The engine is planned to be used for the third stage of "Cyclone-4".
