YF-102RV is the high-altitude open-cycle liquid-oxygen/kerosene derivative of YF-102 for the Long March 12B second stage. China Aerospace Science and Technology Corporation describes one YF-102RV operating in the second stage, inheriting the core YF-102 technology while adapting the engine for near-vacuum operation with pump-front gimbal and a large-area-ratio nozzle. This exact propulsion record does not infer unsupported thrust or specific-impulse figures.
