A Case Study of AI DEFENSE Applications in Major Northeast Asian States and Strategies for Building a ROK’s AI-based National Defense System

Purpose: The sequential combination of AI algorithms, or problem-solving commands, can increase aware-ness of battlefield situations. This article intends to analyze the efficiency of AI and to discuss the implications of Northeast Asian neighboring countries application of AI in military affairs. It also explores the ROK s strate-gies for an AI-based defense system. Method: For better analysis, as a part of case studies, this article reviews the U.S, China, Japan, and Russia s AI application to the national defense, and tries to draw out implications to the ROK s construction of an AI-based defense system. “The military utilization areas of AI are surveillance and reconnaissance(ISR), military, cyber operations, information operations, command and control, semi-autonomous and autonomous vehicles, and autonomous weapons systems” Results: IF we draw out suggestions from neighboring countries are as follows, first, mid-to-long-term AI power acquisition plans should be prepared. Second, AI-based intelligent surveillance, command control, infor-mation, firepower, maneuvering, and protection capabilities must be reinforced. Third, we need to expand our ability to support operations based on AI. Fourth, the development of large-capacity tactical network technolo-gy is necessary for the effective operation of the AI combat system. Conclusion: This article concluded that the ROK s AI autonomous combat system capability should be streng-thened to achieve battlefield superiority. Bracing for the threat from neighboring powers in the changing security environment of Northeast Asia, the ROK should also use AI as a driving force for future military innovation cherishing AI ethics. It needs to improve the ability to utilize AI by strengthening the competitiveness of technology through the cooperation of the pri-vate-government-military circles cooperation.
