The RD-58 (manufacturer designation 11D58) is a rocket engine, developed in the 1960s by OKB-1, now RKK Energia. The project was managed by Mikhail Melnikov The engine was initially created to power the Block D stage of the Soviet Union's abortive N-1 rocket.[1] Derivatives of this stage are now used as upper stages on some Proton and Zenit rockets.[2] An alternative version of the RD-58 chamber, featuring a shorter nozzle, was used as the N-1's roll-control engine.

The Buran spacecraft used two descendants of the RD-58 as its main engines.

The RD-58 uses LOX as the oxidizer and kerosene as fuel. It features a single gimbaled chamber, radial centrifugal pumps with auxiliary booster pumps, and an oxygen-rich gas generator. Recent modifications include a lightweight carbon-composite nozzle extender.
