The RD-0255 is a propulsion module composed of an RD-0256 main engine and a RD-0257 vernier engine. Both are liquid rocket engine, burning UDMH in N2O4. The RD-0256 main engine operates in the oxidizer rich staged combustion cycle, while the vernier RD-0257 uses the simpler gas generator cycle. It was used on the R-36MUTTKh (GRAU:15A18) and R-36M2 (GRAU:15A18M). Subsequently, it has been in the Dnepr second stage and as of 2016 it is still in active service.

Il a ensuite équipé le deuxième étage de la fusée Dnepr et en 2016 il est toujours en service actif. Le RD-0255 est une version améliorée du module de propulsion RD-0228 (indice GRAU : 15D84), lui-même composé d'un moteur principal RD-0229 (indice GRAU : 15D84) et d'un moteur vernier RD-0230 (indice GRAU : 15D79). Le RD-0228 a été développé entre 1967 et 1974 pour le deuxième étage de la première génération du missile balistique intercontinental R-36M (indice GRAU : 15D83), mais il a été remplacé sur les versions ultérieures par le RD-0256. La première utilisation du RD-0228 fut le 21 janvier 1973. Avec les accords START I et START II, le RD-0228 a été retiré et son successeur, le RD-0256 est utilisé uniquement sur la fusée Dnepr, issu de la reconversion du missile.

The RD-0256 is an improved version of the RD-0228 (GRAU: 15D84), itself composed of an RD-0229 (GRAU: 15D84) main engine and a RD-0230 (GRAU: 15D79) vernier engine. The RD-0228 was developed between 1967 and 1974 for the first generation of R-36M (GRAU: 15D83) ICBM second stage, but was replaced on subsequent iterations by the RD-0256. The RD-0228 debut was on January 21, 1973. With the START I and START II the RD-0228 was retired and its successor, the RD-0256, only continued as the Dnepr.

O RD-0228 foi desenvolvido entre 1967 e 1974 para a primeira geração do segundo estágio do ICBM R-36M (15D83), mas foi substituído durante a evolução do projeto pelo RD-0256. O RD-0228 estreou em 21 de Janeiro de 1973. Com o advento dos tratados START I e START II o RD-0228 foi descontinuado e seu sucessor, o RD-0256, só continuou com o foguete lançador Dnepr. (pt)
