Purpose: In preparation for the great security threats surrounding the Korean Peninsula, it is urgent to estab-lish defense space capabilities to acquire prior information and secure precise response capabilities. It is also urgently necessary to establish a military utilization plan for the Korean-style independent navigation satellite, which is reflected in the mid-to-long-term national space development plan. Method: This study used the following research method. First, I predicted the importance of space in defense and the aspect of space war. In addition, it analyzed the trend of strengthening the defense space of countries around the world and derived implications for strengthening Korea s defense space. Based on this, the revision of the law and the improvement of the system were proposed to strengthen Korea s defense space. Results: Revision of Laws and Regulations for Strengthening National Defense Space. The amendment of the Space Development Promotion Act should be made as soon as possible. It is to establish a legal basis for the military to pursue space development on its own. The first option is to enact a law to strengthen the defense space force(special law). The second plan is to revise the current Space Development Promotion Act , add and strengthen security-related clauses. Korea s Defense Space Strategy Development Direction is to strengthen co-operation with advanced countries including the United States for space security, effectively responding to space threats and space risks, and strengthening civil-military space cooperation. Conclusion: While first pushing for the enactment of a special law through the legislation of lawmakers, it will be appropriate to insert and revise provisions related to defense space in the current laws(such as the Space Development Promotion Act, the Defense Business Act, the Armed Forces Organization Act, the Aerospace Indus-try Promotion Act, etc.). It is necessary to give the defense minister full authority on issues related to defense space, and on the other hand, it is reasonable to carry out legislative activities in a way that does not go against the cause of peaceful use of the international community. In addition, efforts should be made to expand sys-tems and organizations to strengthen the defense space and train experts.
