Problem
Access to space remains expensive and constrained by limited availability of reliable, domestically produced liquid rocket engines, especially for commercial launch services that require a range of thrust levels.
Solution
Spacecircling develops and manufactures a family of liquid-fueled rocket engines covering thrust classes from 25 kN to 1 000 kN, providing the full propulsion spectrum needed for commercial launch vehicles. The engines feature high specific impulse (up to 325 s in vacuum) and wide throttling capability (40 %–105 % of rated thrust) to enable flexible mission profiles and efficient stage integration. By establishing production and test facilities in Shaanxi and Sichuan, the company pursues scale‑up and process automation to reduce per‑engine cost. These engines are offered as turnkey propulsion solutions, allowing launch providers to source domestically produced, performance‑validated hardware without relying on foreign suppliers.
Target Audience
Primary customers are commercial launch service companies, satellite manufacturers, and emerging space startups that require reliable, cost‑effective liquid propulsion for small to medium launch vehicles.
