Abstract: The Long March 11 launch vehicle (LM-11) is the only solid launch vehicle within China’s new-generation launch vehicle series, enabling a full spectrum of Chinese launch vehicles. Compared with other China’s LM series launch vehicles, it has the shortest launch preparation time. With the characteristics of appropriate launch capability, quick response, easy-to-use, flexible operation, universal interface and strong task adaptability, LM-11 can better meet the launch requirements for various small networking satellite, replacement and for emergency use. After four successful launches, LM-11 has become the main Chinese launch vehicle oriented to the international small satellite commercial launch market.
