SEOUL — North Korea will build a third 5,000-tonne destroyer by October 2025, state media said, after launching two similar warships this year. Workers at Nampho Shipyard pledged to complete the new “Choe Hyon-class Destroyer No. 3” to bolster naval power and defend maritime sovereignty. Leader Kim Jong Un, who oversaw earlier launches, has vowed to strengthen the navy, with Seoul suggesting Russian help in exchange for troops in Ukraine. Meanwhile, South Korea’s new president Lee Jae-myung has eased cross-border tensions by halting propaganda broadcasts, with Pyongyang following suit.
