The development project for the Korea Space Launch Vehicle-II(KSLV-II) began in March 2010 and carried out its first launch on October 21, 2021, followed by second launch on June 21, 2022. The KSLV-II project was divided into three stages for the entire development period, and configuration manegement was applied from the second stage in this paper. Prior to the application of configuration management, a design change processing process was developed in the Integrated Data Management System(IDMS) as a pre-requisite. Various design changes were processed through configuration control and controlled change management processes after the design was confirmed for each stage of the KSLV-II. As a result of applying configuration management in the development process of the KSLV-II, there were almost no discrepancies between the hardware developed by the research and development department and the 3D model shape handled in the system, which greatly contributed to the assembly and progress of the project.
