This paper deals with the characteristics of the developments of liquid rocket engines in Russia. In 1960s the efforts to achieve the maximum pressure in combustion chamber and specific impulse by applying the closed cycle for liquid rocket engines were made. Lately the decreasing the cost for experimental improvement and expanding international cooperation have been in progress.

This paper treats with the history and current trends in the developments of liquid-propellant rocket engine in Russia and Ukraine which are among world leaders in the technology of liquid rocket engine(LRE). In 1960s formerly the Soviet Union accepted the closed cycle engine for increasing the pressure in the combustion chamber and specific impulse to the maximum. However, since financially difficult times after 1990, they have decreased the cost for the development of new rocket engines. It was achieved by using existing units for new developed engines and minimizing the total number of engines and tests through the reasonable planning in the process for the experimental improvement of LRE. In addition, nowadays international cooperation in supplying LRE for commercial rocket and development of next generation LRE, such as 3 components engines and mathane engines, are proceeding.
