SINGAPORE — South Korea has unveiled an initial roadmap for the development of nuclear-powered submarines, with plans to introduce the first such vessel in the mid-2030s, according to its defense minister.
Ahn Gyu-back told reporters at the announcement of the roadmap today at the South Korean naval base at Jinhae in the south of the country that it was planning to “launch the first nuclear-powered submarine in the mid-2030s, and push ahead with development to enter operational service in the latter half of the 2030s or later.”
Meanwhile the US ally’s Ministry of National Defense (MND) published today what it called the “Basic Plan for the Development of Nuclear Submarines for the Republic of Korea” outlining the key aspects of the program.
The program, which has been designated the “Jang Bogo N Project,” will be developed and constructed domestically using indigenous technologies, including nuclear reactors and the future boats’ energy conversion system.
Calling it a “national strategy project,” the plan further noted that nuclear submarines possess dramatically enhanced operational capabilities compared to diesel-electric submarines, including improved underwater endurance and mobility.
“[They] will play a core role in responding to threats, such as North Korea’s submarine-launched nuclear and missile threats,” it added.
The plan also attempted to allay nuclear non-proliferation and safety concerns, reaffirming South Korea’s pledge to neither seek nor develop nuclear weapons. It would implement nuclear non-proliferation obligations when acquiring low-enriched uranium from the United States, and establish a system of safeguards together with the International Atomic Energy Agency Agency, per the program’s plan.
South Korea has sought to acquire nuclear-powered submarines for over three decades, and only secured approval from US President Donald Trump for US nuclear propulsion technology in October.
The country has also been pursuing nuclear-powered commercial ships in recent years, having secured certification for a nuclear-powered liquefied natural gas carrier and the use of Small Modular Reactors for ship propulsion.
South Korea’s MND expects the program to create more than 40,000 jobs in South Korea’s shipbuilding, nuclear and defense industries, with the submarines expected to be in service for 30 years.
