RD-0120 (rocket engine)
From Wikipedia, the free encyclopedia
The Soviet RD-0120 (also designated 11D122) was the Energia Core rocket engine, fueled by LH2/LOX, roughly equivalent to the Space Shuttle main engine. These were attached to the Energia Core rather than the orbiter, so were not recoverable after a flight.
