The Long March 6C （LM-6C） launch vehicle is a single-core，two-stage liquid oxygen/kerosene launch vehicle within the modified Long March 6 （LM-6）launch vehicle series，and is engineered to achieve a 2-ton payload capacity in the Sun-synchronous orbit （SSO）.As a cornerstone of the new generation of Long March launch vehicles，the LM-6C launch vehicle has been refined with technological and developmental process innovations to shorten the development cycle，enhance the flight reliability and mission adaptability，simply the launch site operations，and heighten the cost-effectiveness and performance capability.It has broken through many key technologies such as the overall configuration optimization of two-stage tailless rocket，the 2.9 diameter foam sandwich common bottom，the highly reliable pressurization technology with strong mission adaptability，and the adaptive augmentation control.In this paper，an overview of the development background and history，characteristics，and technical innovations of the LM-6C launch vehicle is carried out，and the course for its future development pathways is charted.
