Trump says South Korea has approval to build nuclear-powered submarine
The submarine will be built in a Philadelphia shipyard, where South Korean firms have increased investment, Trump wrote on social media
Highlights:
- South Korea also seeks US permission for nuclear fuel reprocessing
- US only shared nuclear sub tech with UK in 1950s
- Experts question necessity of South Korea's nuclear sub acquisition
US President Donald Trump said on Thursday he has given South Korea approval to build a nuclear-powered submarine, a dramatic move that would admit Seoul to a small club of nations possessing such vessels.
The submarine will be built in a Philadelphia shipyard, where South Korean firms have increased investment, Trump wrote on social media.

The US president, who has been meeting with South Korean President Lee Jae Myung and other regional leaders during his visit, also said Seoul had agreed to buy vast quantities of US oil and gas.
Trump and Lee finalized details of a fraught trade deal at a summit in South Korea on Wednesday.
Lee had also been seeking US permission for South Korea to reprocess nuclear fuel.
NUCLEAR RESTRICTIONS EASING?
Seoul is barred from reprocessing without US consent, under a pact between the countries.
"I have given them approval to build a Nuclear Powered Submarine, rather than the old fashioned, and far less nimble, diesel powered Submarines that they have now," Trump wrote on his Truth Social platform on Thursday.
South Korea's Industry Ministry said its officials had not been involved in any detailed discussions about building the submarines in Philadelphia.
While South Korea has a sophisticated shipbuilding industry, Trump did not spell out where the propulsion technology would come from for a nuclear-powered submarine, which only a handful of countries currently possess.
The US has been working with Australia and Britain on a project for Australia to acquire nuclear-powered submarines involving technology transfers from the United States. The US has so far only shared that technology with Britain, back in the 1950s.
Lee said when he met Trump on Wednesday that allowing South Korea to build several nuclear-powered submarines equipped with conventional weapons would significantly reduce the burden on the US military.
He also asked for Trump's support to make substantial progress on South Korea being allowed to reprocess spent nuclear fuel, or on uranium enrichment, something currently not allowed under the nuclear agreement between the two countries, even though South Korea possesses nuclear reactors to generate power.
APPROVAL RAISES QUESTIONS
Lee's predecessors had wanted to build nuclear-powered submarines, but the US had opposed this idea for decades.Daryl Kimball, executive director of the Washington-based Arms Control Association, said the issue of South Korea acquiring such submarines "raises all sorts of questions."
"As with the AUKUS deal, (South Korea) is probably looking for nuclear propulsion services suitable for subs, including the fuel, from the US," he said.
Kimball said such submarines usually involved the use of highly-enriched uranium and would "require a very complex new regime of safeguards" by the International Atomic Energy Agency, which has a key role in implementing the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).
"It remains technically and militarily unnecessary for South Korea to acquire the technology to extract weapons-usable plutonium from spent fuel or to acquire uranium enrichment capabilities, which can also be used to produce nuclear weapons," he said.
"If the United States seeks to prevent the proliferation of nuclear weapons worldwide, the Trump administration should resist such overtures from allies as strongly as it works to deny adversary access to these dual-use technologies."
Jenny Town, who heads 38 North, a Korea-focused research group in Washington, said it was inevitable that South Korean demands for US cooperation on nuclear issues would grow, given recent allegations about Russian technical cooperation to help nuclear-armed North Korea make progress towards acquiring nuclear-powered submarines.
Kim Dong-yup, a North Korea studies professor at Kyungnam University, said the Lee-Trump summit had formalized a "transaction scheme of security guarantees and economic contributions" for maintaining the extended deterrence and alliance in exchange for South Korea's increased defense spending and nuclear-powered subs and US investments.
"In the end, this South Korea-US summit can be summarized in one word: the commercialization of the alliance and the commodification of peace," he said. "The problem is that the balance of that deal was to maximize American interests rather than the autonomy of the Korean Peninsula."
