The RD-58 (manufacturer designation 11D58) was a rocket engine, developed in the 1960s by OKB-1, now RKK Energia. The project was managed by Mikhail Melnikov, and it was based on the previous S1.5400 which was the first stage combustion engine in the world.[1] The engine was initially created to power the Block D stage of the Soviet Union's abortive N-1 rocket.[5] Derivatives of this stage are now used as upper stages on some Proton and Zenit rockets.[6] 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 preburner. Recent modifications include a lightweight carbon-composite nozzle extender.

The current version of the engine is the RD-58M (manufacturer designation 11D58M), which has slightly reduced thrust, but increased isp. An even newer version is under development and is known as the RD-58MF (manufacturer designation 11D58MF). It will reduce thrust to 49.03 kilonewtons (11,020 lbf) to keep the same length but increase expansion ratio to 500:1. This will enable it to gain 20s of isp (to an expected 572s). It will eventually fly on the Blok DM-03.[7] This new version of the engine will be built in the Krasnoyarsk Machine-Building Plant.[8][9]
