Abstract With the rapid development of deepsea technology and equipment, the intensification of deepsea resource competition, the lag of deepsea military control mechanisms, and the need for comprehensive management of the ocean and potential sea battles, major military powers are accelerating the construction of deepsea combat systems, attempting to turn most of the deepsea areas from a public domain state into a new onedimensional battlefield, in order to seek control over deepsea areas, which will accelerate the development of militarization in the global deepsea region. The acceleration of militarization in global deepsea region will in turn promote a leap in deepsea technology, thereby driving the improvement of national ocean military strength and comprehensive national strength, and expanding the space for national development. At the same time, this acceleration will intensify the deepsea arms race, violating the basic principles and spirit of international ocean peaceful utilization, and greatly increasing the risk of major powers’ war. However, due to the significant investment in the development of deepsea militarization, the potential risks from widespread application of artificial intelligence technology and the harsh geographical and fragile ecological environment of the deepsea will also pose constraints and challenges to the accelerated development of deepsea militarization.
