Perils of the Deep: The Dangers of Submarine Proliferation in the Seas of East Asia

Abstract Greater numbers of submarines are being acquired in the Asia-Pacific. This development poses challenges in the region for preventive diplomacy, maritime confidence building, and ensuring the safety of submarine operations. However, countries are extremely sensitive about submarine operations and meeting these challenges will be difficult. The article discusses technological developments with submarines and antisubmarine warfare and the implications for regional naval operations. It identifies the risks associated with increased numbers of submarines, particularly in the narrow seas of East Asia, and recommends measures that might mitigate the adverse consequences of submarine proliferation, including enhancing submarine safety. It concludes that there is a pressing need to start discussion of these measures in regional forums.
