South Korea: Nuclear-powered subs enter race with Pyongyang

With the US eager to redefine the terms of its alliances in Asia, President Donald Trump last week publicly endorsed the idea of South Korea building and operating nuclear-powered submarines, adding that the first vessel will be made in the US.

"South Korea will be building its Nuclear Powered Submarine in the Philadelphia Shipyards," Trump wrote on his Truth Social platform.

Seoul was quick to praise this decision — South Korean Defense Minister Ahn Gyu-back told a parliamentary meeting on the same day that a nuclear-powered submarine would have "huge" military significance. South Korea currently operates conventional submarines, which run on a combination of diesel and electric power. But nuclear-powered vessels would offer improved speed and endurance to counter North Korea's capabilities, according to Ahn.
