The Liqing-2, a first-stage engine for the Lijian series rockets, features a 110-tonne thrust capacity utilizing pin injection technology in both its gas generator and thrust chamber. CAS Space noted that the engine's thrust ratio can be adjusted between 50 to 100 percent, with a maximum ground thrust of 110 tons.
The development of the Liqing-2 engine was approved in the second quarter of 2023, with production commencing in the first quarter of 2024. By early 2025, the engine had successfully undergone a full-scale liquid flow test, assembly, and final delivery assessment.
The Lijian-1 series rockets, a key component of China's commercial space sector, have so far launched 57 satellites across five successful missions.
CAS Space, a commercial spaceflight enterprise, was founded by the Institute of Mechanics under the Chinese Academy of Sciences.
