From USNI news:
Korea Submarine Update
On Wednesday,
South Korean President Lee Jae Myung said the
Republic of Korea Navy wants to build its planned fleet of nuclear-powered attack boats at home rather than in the U.S.
Speaking to foreign reporters in Seoul, Lee affirmed comments last month from
Defense Minister Ahn Gyu-back that the RoK Navy wanted to build the nuclear attack boats in Korea instead of the Korean-owned
Hanwha Philly Shipyard.
Furthermore, Lee said that Seoul is specifically interested in U.S. help to acquire nuclear fuel for its fleet.
“We’re not asking for construction or tech transfer. Just approval for fuel supply,” he said.
In late October,
President Donald Trump said Korean nuclear-powered attack boats would be built at Philly Shipyard, but since the announcement, Korean officials have gently suggested it would make more sense to build the submarines in Korea.
Lee does need Trump’s approval to acquire fuel to power the new class of attack boats.
The 2015 Atomic Energy Peaceful Uses Agreement restricts the amount of nuclear fuel South Korea can enrich and would need U.S. permission to produce the fuel it would need for the new boats.
As USNI News reported last month, South Korea has been trying for decades to develop a nuclear-powered submarine force to counter North Korea’s emerging fleet of conventional submarines armed with nuclear ballistic missile. The RoK Navy wants attack boats that can patrol beyond the limitations of a diesel-electric propulsion system.
“Underwater operations with the fleet of diesel-electric submarines are restricted to detecting and countering the North’s SLBM [submarine-launched ballistic missile] threat,” then-
President Moon Jae-in said in 2018. “On the other hand, nuclear-powered submarines will help conduct patrols for much longer periods to thwart North Korean SLBM attacks.”
Now Seoul and Washington are figuring out where the fuel will be enriched amid concerns the fuel could be used to develop a South Korean nuclear weapon.
“Some in the U.S. government seem to be a bit cautious,” Lee told reporters. “We make our position clear: We have no intention of arming ourselves with nuclear weapons. It’s realistically impossible.”
