Beijing-based aerospace firm CAS Space announced the completion of its Liqing-2 liquid oxygen kerosene rocket engine, a milestone in China’s rapidly growing commercial space sector. The 110-tonne thrust engine, designed for the Lijian series rockets, features advanced pin injection technology to optimize performance in gas generators and thrust chambers.
Developed in just under two years, the engine’s thrust can adjust between 50% and 100% capacity, hitting a maximum ground thrust of 110 tonnes. CAS Space confirmed that the Liqing-2 underwent rigorous testing, including a liquid flow trial, before its 2025 delivery.
The Lijian-1 rockets, which use the Liqing engines, have already launched 57 satellites across five missions, positioning China as a key player in cost-effective space infrastructure. Founded by the Chinese Academy of Sciences’ Institute of Mechanics, CAS Space aims to accelerate satellite deployment and commercial space innovation.
This advancement aligns with China’s broader push to expand its ‘New Space Economy,’ blending state-backed research with private-sector agility. Analysts say the Liqing-2 could lower launch costs for startups and governments alike, fostering new opportunities in Earth observation and global connectivity projects.
