  The TH-12 (Chinese: 天火-12; pinyin: Tiānhuǒ-12, lit. Sky Fire 12) is an oxidizer-rich gas-generator cycle rocket engine burning LOX and kerosene under development by Space Pioneer. The TH-12 utilizes 3D printing and has the highest target thrust among all commercial rocket engines in China. The engine features deep throttling for reusability, re-ignition, thrust vectoring, and multi-mode starters.
