Purpose: The study aims to examine the strategies and trends of military space power in neighboring countries and derive implications for ROK’s building space Power. This article tackles both conceptual and empirical dimensions of this topic through a series of four linked questions: (1)What is Sun Tzu s Strategy and how does it relate to space; (2)What is neighboring state s space strategy surrounding the Korean Peninsula?; (3)What kind of implications can we draw from the neighboring countries space strategy?; (4)What are policy alternatives for the ROK to build space power? Method: For better analysis By using the Sun Tzu s five fundamental factors(do[道] the way, cheon[天] seasons, chi[地] terrain, cheng[將] leadership, and beub[法] management), a factor that predicts the success or failure of a strategic plan, this study attempted to draw implications and policy alternatives for the ROK by looking at the cases of military space force construction in neighboring countries. Sun Tzu introduces this as the docheonchichengbeub . Results: The policy options for the ROK military by applying Sun Tzu s Osa(五事) as follows. First, In terms of Do(道), the Moon Jae-in government has a strong will to build a foundation for strengthening space power under the responsible defense policy for the early return of wartime operational control. Currently, Korea s space power remains insignificant compared to neighboring countries. Efforts should be made to lay the foundation for the creation of an advanced space force by sharing such a vision with the leader. Second, the construction of space power in the U.S., China, Russia, and Japan surrounding the Korean Peninsula is gradually intensified as the factors of Cheon(天) and Chi(地). Therefore, there is a need for South Korea to create a road map for the construction of space power and implement positive space power building policies. Third, as a factor of Cheng(將), the Korean military has many problems to be improved in terms of organization, institutional maintenance, education, and technology development for space power. Fourth, to develop military space power in terms of the establishment of a policy base, laws and systems supporting space development shall be reorganized, and at the same time, the con-cept of space strategy and operational doctrine shall be developed, a defensive deterrent alliance strat-egy suitable for mid-sized countries, and a space power construction plan has to be established to util-ize space power centered on the Joint Chiefs of Staff. Conclusion: It is required to strengthen the agility of operations by increasing the linkage between unmanned systems and satellites for the enhancement of public values such as saving lives in the emer-gency. Hence, it is suggested that the launch of a small satellite that are equipped with a high-performance optical camera has to be carried out earlier than scheduled. To respond to North Korea s ballistic missile threats, it is requested to expand high-resolution military reconnaissance satellite as-sets which are equipped with early warning capabilities.
