Energia was a super-heavy lift launch vehicle. It was designed by NPO Energia of the Soviet Union for a variety of payloads including the Buran spacecraft. Control system main developer enterprise was the Khartron NPO "Electropribor". The Energia used four strap-on boosters each powered by a four-chamber RD-170 engine burning kerosene/LOX, and a central core stage with four single-chamber RD-0120 (11D122) engines fueled by liquid hydrogen/LOX.

The launch vehicle had two functionally different operational variants: Energia-Polyus, the initial test configuration, in which the Polyus system was used as a final stage to put the payload into orbit, and Energia-Buran, in which the Buran-class orbiters were the payload and the source of the orbit insertion impulse.

Production of Energia rockets ended with the fall of the Soviet Union and the end of the Buran shuttle project.
