YF-102R
YF-102R is a reusable open-cycle liquid-oxygen/kerosene liquid-rocket engine developed for the Long March 12B first stage. China Aerospace Science and Technology Corporation describes multiple starts, deep throttling, a high-flow pintle injector, and pump-after gimbal; nine YF-102R engines operate in parallel on the first stage, while the related YF-102RV serves the second stage. This exact propulsion record does not infer unsupported thrust or specific-impulse figures.
