China 921 rocket (new generation manned spacecraft)

The code name of China's manned space project is Project 921. The 921 rocket project comes from office 921. The name of the "Long March XX" is mainly because the rocket has not yet been officially named, but in fact it is the result of higher-level rocket technology progress. Some analysts say that the emergence of the 921 rocket was stimulated by the heavy falcon rocket, which has proved to be relevant. Both use the CBC configuration. The first-class rocket of the Falcon rocket shares 27 engines, while the 921 rocket uses 21 engines. Its near-Earth orbit carrying capacity is 70 tons, and its ground-month transfer orbit carrying capacity is 27.5 tons, which is far more powerful than Long March 5. The landed and uplift aircraft of China's manned lunar landing project will not exceed 25 tons in quality, and 921 rockets are enough to complete the task.
