South Korea to develop nuclear-powered submarines to counter North Korea's threat

South Korea announced on Tuesday its plan to develop nuclear-powered submarines to counter North Korea’s missile and submarine-based nuclear threats.

In its statement, South Korea’s Ministry of Defence said the first nuclear-powered submarine is expected to be launched in the mid-2030s and operational by the end of the decade.

The statement marks South Korea’s first official announcement of the project since President Lee Jae-myung sought approval from US President Donald Trump during last October’s summit for nuclear submarine fuel supply.

“Nuclear-powered submarines have far superior operational capabilities compared to conventional diesel-electric submarines, including longer underwater endurance and higher manoeuvrability,” the statement said.

It also noted that the submarines would play a crucial role in countering North Korea’s threats.

During a previous cabinet meeting, Lee said South Korea must accelerate the adoption of artificial intelligence and drone technology while continuing the development of nuclear-powered submarines as a key strategic defence asset for the future.

The Ministry of Defence emphasised that South Korea will not develop nuclear weapons.

It also stated that South Korea will continue to meet its nuclear non-proliferation obligations during the procurement and management of low-enriched uranium for propulsion systems through close consultation with the US.
