Lijian 1 "Yao-1 launch vehicle.
At noon on July 27, 2022, the "Lijian-1" Yao-1 solid launch vehicle 1 arrow and 6 satellites were successfully launched at the Jiuquan Satellite Launch Center, putting the satellite into sun-synchronous orbit (SSO), and "Lijian-1" became the first medium-sized solid launch vehicle successfully launched in China.

At noon on June 7, 2023, the "Lijian-1" Yao-2 carrier rocket carrying 26 satellites was successfully launched at the Jiuquan Satellite Launch Center, putting the satellite into a sun-synchronous orbit. This mission "Lijian No. 1" set a new record for China's multi-satellite launch at that time. After a lapse of 5 months, "Lijian No. 1" is about to play again.
On December 11, Zhongke Aerospace held the "Lijian No. 1" Yao-3 rocket departure ceremony at the Zhongke Aerospace Flight Science and Technology Industrialization Base. "Lijian No. 1" Yao-3 rocket is one of the first batch of rockets produced in Nansha, Guangzhou, which has completed all the work before leaving the factory according to the process, and the product functions and performance indicators have met the requirements of the flight mission, and successfully passed the factory review. According to the plan, in January 2024, the "Lijian-1" Yao-3 rocket will carry out the "one arrow and five satellites" launch mission at the Jiuquan Satellite Launch Center to put the satellite into sun-synchronous orbit. The launch coincided with the lowest temperature of the year, and it will be the first launch of the "Lijian No. 1" rocket in a low-temperature environment.

The "Lijian-1" rocket was developed by the Institute of Mechanics of the Chinese Academy of Sciences and participated in the development of the Zhongke Aerospace Company, and is a four-stage solid launch vehicle. The total length of the arrow is about 30 meters, and the maximum diameter of the core stage is 265 meters, with a take-off mass of about 135 tons, a take-off thrust of 200 tons, and a low earth orbit (LEO) capacity of 200 kilometers at an altitude of 200 kilometers and an inclination angle of 40 degrees is 2 tons, 148%, altitude 500 km sun-synchronous orbit (SSO) capacity 15 tons, 111%。"Lijian No. 1" is one of the most efficient solid rockets in use in China, one of the reasons is the use of lightweight materials, such as its first stage using T700 carbon fiber material shell, and the fourth stage using high-performance fiber composite materials spherical heterogeneous solid engine.

"Lijian No. 1" is one of the solid launch vehicles with the largest take-off and strongest capacity in use in China, and its take-off magnitude and capacity are similar to those of the "Jielong-3" rocket. The comprehensive performance of "Lijian 1" has reached the world's leading level of solid launch vehicles.
The "Lijian-1" rocket is mainly used for single and multi-satellite launches of small and medium-sized spacecraft in sun-synchronous orbit and low-earth orbit, as well as the launch of hypersonic vehicles in near-space space. On the basis of the previous two consecutive wins, in 2024, "Lijian 1" will show its strength, and it is planned to achieve 6 rockets leaving the factory and perform at least 4 launch missions throughout the year.
In the future, in the face of the launch needs of medium and low orbit satellite constellations such as rapid networking, the units of "Lijian No. 1" have already been laid out in advance. Located in Nansha, Guangzhou, the Zhongke Aerospace Flight Science and Technology Industrialization Base is a world-class serialized rocket production base built by Zhongke Aerospace, which is mainly used to carry out the production, testing, testing and testing of serialized solid and liquid rockets, with an annual production capacity of 30 rockets.
