How South Korea's nuclear submarine plans could reshape the underwater balance near the first island chain
According to the South China Morning Post, South Korea's plan to develop nuclear-powered submarines by the mid-2030s marks a strategic milestone for the network of US-allied underwater capabilities.

According to the South China Morning Post, South Korea's Ministry of Defence this week unveiled the basic plan for its nuclear-powered submarine programme, providing the first detailed framework since US President Donald Trump granted initial approval. The report says Seoul aims to deliver its first nuclear-powered submarine by the mid-2030s. Citing analysts, the dispatch describes the plan as a strategic milestone for the network of advanced underwater capabilities near the first island chain.
As framed in the SCMP analyst-attributed account, the possible deterrence effects of the programme may be interpreted differently in Beijing and Pyongyang. Statements from Chinese Foreign Ministry spokesperson Mao Ning have maintained the long-standing concern over regional arms-race dynamics; Pyongyang has not issued a direct statement on the programme.
In the coming period, Seoul's budget envelope, technology-transfer arrangements with the United States and the positions of regional partners such as Japan and the Philippines will be key themes shaping the trajectory of the programme. This article is not investment advice.
