"The Energia-Buran project includes the launch system, which is still viable. At least it can be brought back to life. It also includes the "A" rocket units, used in the Zenit carrier rocket, and also engines made today. We proposed using oxygen-kerosene engines instead of the hydrogen central part, and make the first and second stages of five units," he said. "Concerning the carrying capacity, it's difficult to speculate, but it could be up to 70 tonnes, which is sufficient to circle the Moon," Lopota said." "If ambitions and political will are there, this project could be accomplished in a few years without falling behind our American colleagues," [Energia President and General Designer Vitaly] Lopota added.
"The Energia-Buran project was suspended in the 1990s, when five rocket frames at various degrees of readiness were available at the Baikonur cosmodrome and at the Energia corporation assembly premises. They were destroyed. The RD-170 rocket engine, developed for the Energia project, has been upgraded and is used in Zenit Russian-Ukrainian carrier rockets as RD-171, and in American Atlas 5 launch systems as RD-180."
