Beijing Zhongke Aerospace Exploration Technology Co., Ltd. is the first domestic aerospace enterprise with mixed ownership, and it is also the target enterprise that Oriental Aerospace Port focuses on introducing. Relying on the scientific research strength and resource advantages of the Institute of Mechanics of the Chinese Academy of Sciences and the Aerospace Flight Technology Center of the Chinese Academy of Sciences, China Aerospace Science and Technology has been committed to the research and development and integration of space technology and aerospace vehicles as a platform for the transformation of major national scientific research projects, as well as the transformation and provision of technological achievements. Aerospace launch service. The Lijian-1 rocket project also adds a brand-new name card to the Oriental Space Port, which will surely promote the construction of the Oriental Space Port to take a solid step forward.

Lijian-1 Y18 Carrier Rocket Successfully Rolls Off Factory On July 31, the Lijian-1 Y18 carrier rocket successfully completed its final assembly and testing at the CAS Aerospace Industrialization Base and passed the factory acceptance review. It is scheduled to launch nine satellites in one launch from the Dongfeng Commercial Aerospace Innovation Test Zone in the near future.
On July 31, the Long March 1-1 Y18 carrier rocket successfully completed its final assembly and testing at the CAS Space Industrialization Base and passed the factory review. It is scheduled to carry out a “one rocket, nine satellites” launch mission in the Dongfeng Commercial Space Innovation Test Zone in the near future .

From April to July this year , the Lijian-1 rocket maintained a stable pace of “launching every month,” and a routine, high- density launch operation pattern has been fully established. Following the successful launch of five satellites with one rocket by the Lijian-1 Y15 carrier rocket on July 24, the Lijian-1 Y18 carrier rocket rolled off the production line just one week later, further accelerating the batch production and delivery process . Relying on a pulsed production system and reliable technical solutions, the model continues to strengthen its batch delivery capabilities, continuously improve its scheduled launch support system, and solidify its foundation for large-scale commercial spaceflight capacity .

To date, the Lijian-1 carrier rocket has launched 15 times, successfully sending 110 satellites into space with a total payload mass exceeding 16 tons. It is the only domestically produced commercial rocket model to have launched more than 100 satellites.

The LiJian-1 Y18 carrier rocket has completed final assembly and testing and passed factory acceptance. It is scheduled to carry out a “one rocket, nine satellites” launch mission in the Dongfeng Commercial Aerospace Innovation Test Zone in the near future. This will be the 16th flight mission of this type of rocket.

Developed by CAS Space Technology, this rocket employs a four-stage solid rocket motor tandem configuration. It is 30 meters long, has a liftoff mass of 135 tons, and a payload capacity of 1.5 tons to a 500-kilometer sun-synchronous orbit. The first-stage engine boasts the largest propellant load and thrust among domestically operated large solid rocket motors, with a liftoff thrust exceeding 200 tons, enabling rapid launch from both land and sea.

To date, the Lijian-1 series rockets have completed 15 launches, successfully sending 110 satellites into space, with a total payload mass exceeding 16 tons. It is the only domestically produced commercial rocket model to have launched over 100 satellites. From April to July this year, the rocket maintained a high-density launch schedule, with launches every month. Following the successful launch of five satellites with the Y15 rocket on July 24th, the Y18 rocket rolled off the production line just one week later, significantly improving its mass production and delivery capabilities

I. Current Status of the Y18 Rocket
- Factory Delivery and Review : On July 31, 2026, the Lijian-1 Y18 carrier rocket successfully completed its final assembly and testing at the Zhongke Aerospace Guangzhou Nansha Industrialization Base and passed the factory delivery review.1
- Launch plan : A “one rocket, nine satellites” launch mission is planned to be carried out in the Dongfeng Commercial Aerospace Innovation Test Zone in the near future.1
- Pace Comparison : Following the successful launch of five satellites with a single rocket on July 24, the Y18 rocket was successfully delivered just one week later, significantly accelerating the batch production and delivery speed
II. Cumulative Achievements and Milestones

- Total launches : To date, the Lijian-1 rocket has launched 15 times, successfully sending 110 satellites into space, with a total payload mass of over 16 tons.
- The only civilian-commercial rocket to have launched over 100 satellites : The Lijian-1 is the only civilian-commercial rocket model in China to have launched over 100 satellites in total.5
- Market position : With its mature multi-satellite launch configuration and precise separation technology, the Lijian-1 rocket holds the record for the highest number of multi-satellite launches by a commercial rocket (26 satellites in one launch), and has the highest market share.
III. The Regularized Pattern of “Launches Every Month”
- High-frequency rhythm : From April to July 2026, the Lijian-1 rocket will maintain a stable rhythm of “launching every month”, and a normalized high-density launch operation pattern will be fully formed.5
- Production capacity support : Zhongke Aerospace adopts a pulsed, rhythmic production mode, shortening the final assembly and testing cycle to 1 month, and has the capacity to produce more than 10 rockets per year, with a subsequent goal of producing 30 rockets per year.
- Launch site efficiency : Relying on the dedicated workstations in the Dongfeng Commercial Aerospace Innovation Test Zone, the launch site test and launch cycle has been reduced to 10 days, achieving truly “flight-like” operation.
